The CNC Electro-Spark CUT and treatment include a quick mobilization wire treatment and slow wire treatment, which are widely used in the manufacturing industry. What are the conditions for developing the processing efficiency, cutting precision and the surface quality of these two technologies?
The development of the Goal rapid treatment technology
As the name suggests, the treatment of the rapid wire is named after the electrode wire in the cutting process. The fast machining machine is an original power processing machine in my country. It can meet the requirements for the treatment of average and low mold and other manufacture of complex parts, and occupy a considerable amount on the low market.
The biggest advantage of fast machining machine tools is to have a good performance price ratio. Due to its practical aspect and its economy, there is a large market in China. The traditional fast speed treatment uses a cutting process.
In order to improve the quality of the treatment, the manufacturer of the manufacturer of cable treatment tools has referred to the multiple cutting process, which improved the relevant components of the machine tool, and the “machine machine tool Average SO. treatment and improve the quality of the surface.
Currently, the technical indicator of the silk machining machine: the effectiveness of a cut is 180㎜² / min, and the roughness of the surface after a multiple cut is RA ≤ 1.0 μm. / min. These performance indicators seem to be relatively good, but it should be noted that obtaining these indicators requires all connections. The stability of the quality of treatment.
The typical manufacturers of machine tools in production are Suzhou Sanguang, Suzhou Hanqi, Shanghai Special, Beijing Ande, Suzhou Baoma, Suzhou New Spark and a large number of Shanghai.
The status of development of slow cable treatment technology
The accuracy of the precision of the manufacture of molds and requirements for complex surface quality and long lifespan are permanently. It has reached a very high level and is irreplaceable by other treatment technologies.
1. The status of development of the slow treatment technology
(1) Improve the precision of treatment
Several cutting techniques are the fundamental means of improving treatment accuracy and surface quality. Generally, precision is improved by the cut, secondary cut and increased surface quality of more than three times.
Due to the offset of the electrode wire during the corner cutting, the local collapse will be caused. In order to improve local cutting precision, more dynamic corner treatment strategies have been adopted. Such as: automatically modify the treatment speed, automatic water pressure adjustment, control energy treatment, etc.
The high -precision precision treatment circuit adopted by advanced machining machines to slowness is an effective technique for improving the flatness of treatment parts, so that the accuracy of thick parts can be considerably improved; The CNC low speed wire cutting machine can be cut with 0.02 ～ 0.03 ㎜ electrode wire.
In order to ensure high precision treatment, mechanical accuracy, precision of the impulse power and the control accuracy of the servometry of the machine tools (including the control of the mechanical movement, the impulse parameters, the control of the wire system and the work fluid system) have reached a very high level. The water temperature cooling device is used to make the machine’s internal temperature as the water temperature, which reduces the thermal deformation of the machine tool; The performance and precision of high positioning. .
(2) The surface quality is complete
Advanced advanced machining machines adopt an anti-electrolytic pulse power with average voltage to zero, and the damage to the electrolyte has been reduced to a minimum. In addition, due to the improvement of the impulse power, the advanced value, a narrow impulse (microsecond), most of the materials are removed from the gas phase, which removes a large amount of heat. is high, but also considerably improves surface quality. The cutting and treatment of the electro-scarking line with an electrolytic power supply can control the surface deterioration layer less than 2 μm. Abrasion resistance and grinding the harsh cutting cutting blade of the cut are even better than the mechanical grinding treatment.
(3) Improve treatment efficiency
Due to the development of nano-class level power supply technology and detection, control and anti-interference technologies, the treatment of treatment of treatment machines slowly is also improved in continuous. The current maximum processing efficiency of advanced treatment machines with slow wire can reach 500㎜ 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 can reach 500㎜ ² / min. The effectiveness of treatment of larger thickness parts has practical meaning. For the treatment of the thickness change part, the treatment parameters are automatically adjusted by automatically detecting the thickness of the treatment of the treatment container to prevent the cut of the wire and obtain the maximum processing efficiency of the condition.
In addition, automatic automatic quick wire technology launched by advanced slow wire treatment machines, automatic wire wear <15 S improves the efficiency of processing operations; Perform a double double switch treatment. Use thick silk for the first cut. To improve precision, it can save from 30% to 50% of the cutting time.
(4) The development of automation, intelligence and computerization
During the processing process, in order to reduce the intervention of people and ensure that the expected process indicators have been affected, automation, intelligence and computerization of silk processing reached development corresponding.
The complete system of expert process for slow wire processing machines gives complete parameters according to treatment requirements. Not only the number of common electrode wires and corresponding part materials, but also the treatment parameters for special materials such as PCD and PCBN. 度和效率哪一项优先的加工策略来生成各自的规准；放电专家系统应付切割中的随机因素 ， 在切入、切出、截面变化、中心切割、接近边缘切割、大 in the circumstances of the top – the section of the section of the section, during treatment, the adaptive control strategy and The automation control function is used to obtain a stable and effective treatment in continuous silk.
The unspeakable automatic detection function is also very practical. Without pilot operation.
The CNC system of the tool-machine is equipped with a standardized mechanical interface to form an intelligent manufacturing system. .
2. The technical level of the machine-machining machine slowly in each grade
Slow machining machines can be divided into four grades: high, high-end, adjustment and entry. Typical manufacturers of slow-slight mobitation machine tools include GF Swiss treatment patterns (formerly Achichemir), Makino, Japan, Midi Mitsubishi, Japan, Sattick, Japan, Western Japan, Frank, Japan, etc.

These machine tools are also widely used for the treatment of precision stamping mold.
(3) slowly execution of machining machines in the average range
This machine tool is generally produced by Switzerland and the manufacturing factories of Japan in China. Generally, a non-resistant anti-electrolytic power supply is used and has a water treatment and cutting function. The maximum processing efficiency of practical treatment is 150 to 200 ㎜² / min, the best surface roughness is RA <0.4 μm, and the cutting precision can reach ± 0.005㎜. are cut.

This machine tool is generally a Taiwanese machine-tools or a national R&D and production machine. Generally, the more cutting process and repair can stabilize the surface sweetness of approximately RA0.8 μm, and the treatment of treatment of treatment is ± 0.008㎜. son.
In general, compared to rapid mobilization machining machines, treatment machines slowly to transfers have very obvious superiority in the effectiveness of treatment, precision and surface quality. Although the price of slow silk treatment machines is more expensive, with the rapid development of manufacturing, it will be applied more and more in various treatment areas.
