China CNC cutting machine transition from extensive to intensive management

China CNC cutting machine transition from extensive to intensive management
Although China's CNC cutting machine start over, but by the downstream machinery processing and other related industries, demand for support, the rapid development of the industry as a whole, the scale is also growing. But

For now, although the strength of many companies has improved, but still in the extensive type of business model. Due to excessive competition, product homogeneity serious, resulting in profits empty

Cramped, but also to the development of many companies fettered.

Price competition in teflon hose the adverse market environment, a large number of domestic manufacturers and brands is not prominent, the lack of technological innovation, heavily dependent on foreign advanced technology, lack of core

Competitiveness. Meanwhile, rising labor costs, coupled with the rise in raw materials also greatly increased the number of corporate cost pressures. From the above phenomena can be predicted, intensive hair

Exhibition mode will certainly be a lot of CNC cutting machine tool enterprises in the future development direction.

Transition from extensive to intensive, low-technology that is changing the content, low management level, low-cost-effective manner, to the high-tech, high capital levels,

High level of management, high economic quality, high cost of operation.

A CNC cutting machine tool industry demand "strength training"

Walking intensive development path, you first need to do is to change their concepts, and establish long-term development of the concept and to develop a viable goals and plans.

Meanwhile, CNC cutting machine tools companies need to come out from the price competition, steering practicing internal strength. "Focuses on the optimization of product structure, product quality improvement, the core technology

Technique mastery and innovation, and the growing influence of corporate brand. Of course, this series of shift requires more capital investment enterprises, which, CNC cutting machine tool enterprises

Industry also needs according to their own circumstances, input-output ratio in the future to make a scientific estimate, so as to selectively invest for a gradual transition.

Second, multiple channels to improve operational efficiency

Intensive management in order to improve efficiency as the ultimate goal, take intensive development path, be sure would like to "low-input, high-yield" business goals, which requires NC

Cutting machine tool companies from many aspects change is undertaken.

On the one hand, companies need to constantly improve enterprise management level, to improve the overall performance management, optimize departmental structure, human resources and avoid waste of time,

While optimizing internal competition mechanism, improve the professional quality of employees.

On the other hand, CNC cutting machine tool enterprises may wish to try high-tech business, to develop computer network engineering, office tools through improved operational efficiency and enhance

.

Third, the development socketless fitting of CNC cutting machine tool enterprises centralization

Strengthen the supply chain upstream and downstream enterprises with close ties to form a strong competitive centralized district of CNC cutting machine, CNC cutting machine for some merchants

And enterprises, enhance their competitiveness and expand market share, has important significance.

Good industrial plan to promote industrial upgrading

CO2 laser cutting machine with fiber laser cutting machine comparison

CO2 laser cutting machine with fiber laser cutting machine comparison
From the modern laser cutting, welding machine applications and the technical requirements of the user point of view, laser cutting, welding is undoubtedly the future direction of development of high power, large format

, High efficiency, a molding, high intelligence.
HGLaser Fali Lai has been committed to high power laser and plasma technology applications. The primary focus here is CO2 and fiber laser cutting machine laser cutting machine processing

The difference:
First, as the mainstream of traditional laser cutting, welding equipment are used CO2 laser, can be stabilized teflon hose within 20mm cutting carbon steel, 10mm stainless steel within, 8mm

The following aluminum alloys. Fiber laser cutting of thin plate 4mm or less obvious advantages, by the impact of solid-state laser wavelength when it is of poor quality in the cutting plate. Laser cutting

Cutting machine is not a panacea, CO2 laser wavelength of 10.6um, solid state lasers such as YAG or fiber laser has a wavelength of 1.06um, the former is more likely to be non-metallic

Absorption can be high quality for cutting wood, acrylic, PP, glass and other non-metallic materials, which are not easily absorbed non-metallic, non-metallic materials, it can not be cut

However, when confronted with two lasers copper, silver, aluminum high reflective materials when they do nothing.
Secondly, because of both the CO2 and fiber laser wavelength difference of one order of magnitude, the former can not be used in optical fiber transmission, optical fiber transmission which can be used, greatly increasing the

The degree of processing flexibility. Early in the fiber laser market before, in order to achieve three-dimensional processing, we use highly sophisticated optical technology through the joint action with the

States combined CO2 laser reflector system will lead to a three-dimensional surface surface to achieve a three-dimensional CO2 laser machining, precision machining of this technology because of the technical limitations of domestic primary

Rests in the hands of very few European and American countries, expensive, high maintenance requirements, the fiber laser market share gradually expanding at the same time has been gradually losing its market.

The fiber laser because it can be transmitted through the fiber, the degree of flexibility than ever before, especially for the automotive industry, because basically about 1mm thin surface

Processing, fiber laser with the same flexible robotic systems, low cost, less point of failure, easy maintenance, fast and doing my part to firmly occupied this city

Field.
Again, the fiber laser photoelectric conversion rate of up to 25%, while the CO2 laser photoelectric conversion rate of only about 10% in electricity consumption, cooling systems and other aspects of supporting light

Advantages of fiber lasers is fairly obvious, if the fiber laser manufacturers some more, and then right price point, and solve the plate cutting process, CO2 laser subjected

Threat will be large. However, socketless fitting the fiber laser as a new laser technology, penetration is far less CO2 laser, its stability and reliability, after-sales service

Convenience market's long-term remains to be seen.
It is worth mentioning that, according to international safety standards, hazard rating of 4 laser, CO2 laser is the least harmful one, while the fiber laser wave length due to the human body by the

So great damage to the eyes, are the most harmful one, for security reasons, fiber laser processing needs fully enclosed environment.
In addition, the fiber laser with a robotic flexible manufacturing systems in the automotive industry and supporting industries, high-status a long time, used to be monopolized by foreign integrators, nearly

Years as the financial crisis and the automotive industry production technology continues to improve, especially in the domestic high-end manufacturers such as laser technology HGLaser Fali Lai in support of national policy

On technology research, many foreign car brands and high-end national brand gleaned crabs, the share of foreign high price arrogant and secretive veil has been lifted, tearing, laborers

Laser Farleylaserlab car users in recent years to provide automotive BIW welding, laser weakening car dashboard, airbag laser welding, car bumpers, car

Doors, columns and other robots in flexible cutting, laser welding car bumpers, car exhaust pipe line welding system, car gearshift sleeve automatic laser cutting equipment, etc., in a

Households live 24 hours a stable and efficient production, allowing users praised the laborers Fali Lai also let foreign integrators shouted, "wolf"!
In summary, laser applications should be directed towards the application of high-power CO2 laser in a more stable, more large-format, faster machine. 2mm below the surface for processing

Fiber laser is an advantage.

hydraulic hose reinforcing material, which has several

Hydraulic hose fittings, currently used and is studying the skeleton data to develop inclusive of cotton, nylon, high-strength steel wire, flax, linen, polyester, glass fibers, asbestos and carbon fiber, rayon and polypropylene, convention, from Select strengthen these categories data, as a decisive factor in voltage grade.

        When dealing with those hose adapters more special fabrics such as polyester and polypropylene, it is necessary very careful to assure precise heat setting level, or when the onset of vulcanized rubber hose should not have deformed.

        In the use of polypropylene, it is necessary to think about curing temperature carefully. Degrees premise, since in many places, this temperature is very close to the softening point of the substrate. When using this type of yarn or fabric, special adhesive system is also required in order to guarantee the hose and components with plenty of well-organized and the Heart of the bonding results.

        Glass fibers and asbestos fibers have been used for steam hose and other heat-resistant hose. Of course, the wire is also used for such use.

        The presentation of a new carbon fiber gum gum category can be used, but the current cost of this new information is high. Therefore, in addition to over the coming years in the space outside the scope does not extend to use; and carbon fiber on which points are worth noting: For tensile strength as compared to the carbon fiber reinforced fiberglass difference information with little or no two who has a high tensile and low density values ​​- equivalent to 25% of steel, however. great benefit of the use of carbon fibers reinforced with such media is high strength steel having a large data five or six times greater than the glass fiber characteristic modulo value, characterized in modulus can be used as a measure of tensile load, which can support the specific component of the beam and not flat clothes, thus. subsequent carbon fiber tends to be used for the reinforcement of metals and ceramics, and not as normal that the pure fiber data: it is Christ in the rubber industry can be very useful in the manufacture of fittings and hydraulic system dynamic sealing,

        Another high-strength, high cost fibers are chemically aromatic amine polyphenol family, a member of the demand is high strength, excellent heat and chemical resistance of places, with it specifically useful. The usefulness of the system include hose: Heavy launch machine (such as persistent heavy-duty engine and diesel engine vehicles convergence refrigeration and heat pipe) and subsea wells seawater for use on equipment-based high-pressure hose and so on.

hydraulic valves - Flow control valves

An adjustment between the spool and the valve orifice area and local resistance it generates flow rate is adjusted to control the velocity of the actuator. Flow control valve use is divided into five kinds. ⑴ throttle: fixed orifice area in tune after the load in a uniform pressure changed little less demanding and motion actuator velocity remained largely stable. ⑵ control valve: pressure changes in load can keep the throttle valve pressure drop is constant. Thus, in the orifice area after it is set, regardless of how the changes in load pressure, control valve can maintain a socketless fitting  constant flow through the throttle valve, so that the movement of the actuator speed and stability. ⑶ shunt valve: no matter the load size, can make the same oil source for the two actuators for the same amount to get equal flow diverter valve or sync valve; been prorated for the proportional flow diverter valve. ⑷ manifold valve: the role of contrast with the diverter valve so that flow manifold valve flow prorated. ⑸ flow diversion valve: china hydraulic hose both shunt valve and manifold valve two functions.

hydraulic valves - directional control valve

Use is divided into one-way valve and valve. Check valve: allows only unidirectional flow in a pipe connected, the reverse is cut off. Valve: change to a different line relationship between the pass ﹑ ﹑ off the spool in the valve body according to the working position of the number of two ﹑ three, etc.; according to the number of channels controlled by a two-way communication ﹑ ﹑ ﹑ Tee Five-way, etc.; tube fitting according spool drive motor sub-manual ﹑ ﹑ ﹑ electric hydraulic, etc.. Figure 2 is a three way valve works. P is the supply port, O is the oil return port, A ﹑ B is a leading actuator output. When the spool is in the neutral position, all ports cut off, the actuator does not move; when the spool is moved to the right position, P-and A-pass, B, and O-pass; when the spool is moved to the left position, P and B Tong, A and O pass. Thus, the actuators can be positive ﹑ reverse movement.
The late 1960s, in the several hydraulic control valve developed on the basis of electro-hydraulic proportional socketless fitting control valve. Its output (pressure ﹑ flow) with the input signal can be continuously changed. Electro-hydraulic proportional control valve according to different functions, accordingly divided into electro-hydraulic proportional pressure control valve ﹑ electro-hydraulic proportional flow control valve and electro-hydraulic proportional directional control valve.

hydraulic valves - Flow control valves

An adjustment between the spool and the valve orifice area and local resistance it generates flow rate is adjusted to control the velocity of the actuator. Flow control valve use is divided into five kinds. ⑴ throttle: fixed orifice area in tune after the load in a uniform pressure changed little less demanding and motion actuator velocity remained largely stable. ⑵ control valve: pressure changes in load can keep the throttle valve pressure drop is constant. Thus, in the orifice area after it is set, regardless of how the changes in load pressure, control valve can maintain a manifold block constant flow through the throttle valve, so that the movement of the actuator speed and stability. ⑶ shunt valve: no matter the load size, can make the same oil source for the two actuators for the same amount to get equal flow diverter valve or sync valve; been prorated for the proportional flow diverter valve. ⑷ manifold valve: the role of contrast with the diverter valve so that flow manifold valve flow prorated. ⑸ flow diversion valve: both shunt valve and manifold valve two functions.

the factors that affect the high-pressure hose assembly

Affect the use of high-pressure hose assembly of many factors, following a brief introduction for everyone:

1, hose size
Hose diameter should be appropriate, too small diameter pipeline will increase the flow rate of the medium, the system heat, reduce efficiency, and will produce excessive pressure on the overall system performance, if the hose with hose clamps fixed or through spacer plates, etc., we should also pay attention to the outside diameter of the hose.

2, the temperature range
Users should be allowed in the hose quality specifications used within a temperature range of hose. If the working environment temperature exceeds this range, it will affect the life of the hose, which will greatly reduce the ability to withstand pressure. Operating ambient temperature is too high or too low, long-term system, we recommend using the hose jacket.

3, the chemical compatibility
If you use special hydraulic banjo fitting medium, users should ensure that their choice of hose assembly hose inner and outer, joints and O-ring compatible with the media.

4, working pressure
Generally refers to dynamic pressure hose hose in continuous maximum allowable working pressure. In accordance with the provisions of the relevant international standards for hydraulic hose safety factor is generally recommended working pressure of the hose is usually a quarter of the minimum burst pressure values.

5, the impact stress and fatigue life
The selection is based on the hydraulic hose system design maximum pressure value determined. As the hydraulic system pressure value is usually dynamic and sometimes impact pressure, impact pressure peak is much higher than the maximum system pressure. However, the system generally have a relief valve, the impact pressure of the hose will not seriously affect the fatigue life. For particularly frequent shock pressure of the hydraulic system, suggested the use of particularly resistant to impact pulsation hose products.

6, the friction
Hose when used usual contact or friction with hard objects, the proposed increase in the external hose spring jacket.

cloth hose specifications fabric hose solution

Cloth conveyor hose is from the inside layer, multi-layer cloth winding layer and the outer cover. Cloth attracts hose is from the inside layer, multi-layer cloth winding layer, spiral steel wire reinforced layer and outer layer.
Fabric hose wall roughness is mainly because there is no pressure molding molds and rubber thermal refining uneven, due to the low temperature extrusion, rubber compound containing recycled plastic is also one of the reasons, so in addition to strengthening the extrusion process operating outside ,
The solution:
Inner and outer layer of glue hose assembly recipe is best to avoid using recycled rubber.

water use grout plugs series

First, use
1, connecting all piping systems, tighten all threaded, connected to the gas source (or hydraulic pump), the grout plug on the orifice (or closed-end steel pipe) pressure test, check connections for leaks, put hole spare.
2, opening the cylinder valve or hydraulic pump, so gradually filling the expansion plug, attention must be greater than the filling pressure of air pressure to 2/3, to a predetermined pressure to grouting.
3, grouting begins, there is a lot to be back to the pulp slurry benefit out of the mouth, and then fractionated slowly pressurized to a predetermined pressure grouting, or easily form a large pressure differential. Grout should always check the gas cylinder valve pressure gauge, such as the reduction should immediately add fill.
4, filling a long time, you hydraulic flanges must check whether the channeling pulp, around the plug back plasma phenomena, if any, should stop filling, release the pressure, loosen the upper and lower inflatable plugs, inflatable plugs is to prevent the consolidation and difficult to remove.
5, the end of the grout, you must first let go of grouting pressure, inflation pressure and then let go, do not let go of the first inflation pressure to prevent grout plug injection, resulting in accidents.
6, after filling, simply plug into the filling tube closed at one end, the inflatable around 0.5Mpa, rinse cycle can be carried out.
7, grout plug after removing the hose into the plasma tube, respectively, back to the slurry pipe connection rinse.
8, together with the porous grout, all piping must be parallel to the line, and not twist and tangle together, hydraulic couplings to prevent a Fasheng security incidents affecting the other hole.
9, after prolonged use, you should plug the bottom apart for cleaning grout, on the butter.
10, drilling discovered over a longer cracks or broken, it may happen channeling pulp, around the plug, return pulp, shall also put an upper end of the trachea to the grout plug, if channeling pulp, around the plug, return pulp, washed with high-pressure gas discharge, can prevent jams.

External lubricants

Lubricant in the plastics processing flowability of the resin to improve the releasability and products to prevent the machine or mold adhesion and internal defects.

General increase in the molding cavity or onto the surface. Common PVC lubricants are fatty acids and their salts, long chain aliphatic hydrocarbons. The mechanism of

action based lubricants can be divided into external PVC lubricant and internal lubricant.
(1) External Lubricant: The lubricant for molding resin compatibility is poor, so commonly used in the molding machine or the mold, it forms a lubricating layer

between the resin, to facilitate resin flow and mold release products such as paraffin.
(2) an intenal lubricant : Lubricant such good compatibility with the resin, often incorporated into the resin, reduce the melt viscosity of the resin, to improve

their mobility. Such as butyl stearate, lead stearate. Stearic acid salts as well a lubricant is effective stabilizers.
