The price of wire cutting, why is the price difference tens of thousands, and what is the difference

Some of the so-called medium silk is fast wire walking, making a little more advanced, with a cabinet.

The cost of the same type of fast filament and medium filament in the world is not worse than 20,000. It's about the cost of doing business, or the business strategy.

This depends on whether you know the goods, the expensive ones are not necessarily good, and the good ones are not necessarily cheap.

Generally, the wire cutting processing fee = cutting circumference * material thickness * unit price. It is not possible to generalize, but also to look at the scale of production. It can also be calculated in terms of cutting area, and the fast wire cutting is about yuan square millimeter.

Wire EDM classification.

1) The wire walking speed of EDM wire cutting is 6 12 m s, and the electrode wire moves at high speed, and the cutting accuracy is poor.

2) Medium wire EDM wire cutting is a new process developed in recent years to realize the function of frequency conversion multiple cutting on the basis of fast wire wire cutting.

3) The wire walking speed of EDM wire cutting is that the electrode wire does low-speed unidirectional movement, and the cutting accuracy is very high.

Suzhou Baoma is the best to use! Stable, long service life, high finish, and the included HF software is super easy to use for variable taper and upper and lower profiles.

Medium wire cutting, also known as medium wire cutting, medium speed wire cutting machine, medium wire cutting machine tool, etc., is a kind of machine tool between slow wire and fast wire cutting, is a new type of machine tool.

When purchasing, you must find a famous brand, the quality is first, the service is reliable, I use the Suzhou Sanguang brand in the wire cutting is very good, the speed is fast, the cutting effect is good.

It's better to use really hard to say. If the pure technology is still Suzhou Sanguang, Suzhou Sante, Suzhou Baoshige, Kunshan Rui are good, after all, the materials and the best will not be bad. If it is said that the machine tool at about 10W has universal applicability in terms of cost performance and positioning, you will not regret buying it under normal circumstances.

Suzhou Sanguang wire cutting programming system is super garbage, it is recommended that you think twice when buying.

The wire is all junk goods, and there is no precision and finish.

The common model of wire cutting is to add multiple cutting functions on the basis of traditional fast wire cutting, reduce the running speed of molybdenum wire or install a gem wire guide, with these several functions, the accuracy and surface luminosity of the cutting workpiece are improved compared with fast wire wire cutting in the early stage (first two months) of wire cutting; However, with the passage of time, the processing effect of medium wire cutting gradually weakened, so that later, many customers purchased medium wire cutting were used as fast wire cutting.

1. The multiple cutting function of the medium wire makes the loss of molybdenum wire increase after processing the workpiece of the same area, which will affect the accuracy and luminosity of the workpiece, and most of the medium wire on the market is continuing to use the pulse power supply of the original fast wire cutting, and the pulse power supply is not suitable for the characteristics of multiple cutting of the medium wire at all.

2. The middle wire reduces the running speed of the molybdenum wire, and also reduces the jitter during the processing of the molybdenum wire, which is helpful to improve the accuracy and surface gloss of the workpiece, but the stability of the front guide wheel is really decisive for the jitter of the molybdenum wire. There are many users who blindly believe that reducing the wire speed, many times of small current tool repair will definitely bring high gloss, but it has been proved that once the service life of the guide wheel is over, the surface luminosity of the workpiece processed by the medium wire after many cuts is not as good as the surface of the workpiece cut by the fast wire cutting of the newly installed guide wheel.

3. The installation of gem wire guide wire cutting in the wire cutting is mainly based on the guide structure of the slow wire and the perforator, a common point of the slow wire and the perforator is that the travel speed of the electrode wire and the electrode is very slow, but the first cutting wire speed of the wire cutting is 40-60 times that of the slow wire, which produces high-speed friction and high temperature, which also makes the gem wire guide on the slow wire and the perforator not suitable for the requirements of the wire, and is quickly damaged and affects the processing effect.

Wire cutting belongs to EDM, and the wire cutting equipment is generally composed of pulse power supply, automatic control system, machine bed and working fluid circulation filtration system. The pulse power supply provides discharge energy for EDM; The automatic control system maintains an appropriate clearance distance between the electrode and the workpiece (usually a few microns to hundreds of microns) to prevent abnormal conditions such as short circuits and arc burns. The machine tool provides support for the machining process, and maintains a certain accuracy of the relative movement of the electrode and the workpiece, the working fluid helps to pulse discharge, and plays a role in cooling and interstitial deionization (restoring the charged particles in the channel to neutral particles), and the circulating filtration system ensures the effective discharge of the etching products to prevent too many conductive particles in the working fluid and reduce the dielectric strength.

EDM wire cutting is divided into three types: slow, medium and fast. Among them, the slow wire is the highest precision and finish. Braided wire is one of the worst.

Medium wire is one of the most cost-effective, and it is only one-third of slow wire, which is twice as much as fast wire. Most of the more well-known manufacturers are in Suzhou, such as Suzhou Baoma and so on.

The treatment of the remaining parts of the workpiece in the middle wire cutting and multiple cutting processing.

In the investigation, it is concluded that with the development of new technologies, new materials and new processes in the mold industry around the world, in order to enhance the wear resistance of the mold, people widely use a variety of high-strength, high-hardness and high-toughness mold materials, which is extremely beneficial to improve the service life of the mold, but it causes inconvenience to the technical treatment brought about by the remaining parts of the EDM wire-cut workpiece after processing. To deal with the processing problem of the remaining part of the workpiece, so as to ensure the surface quality and surface accuracy of the remaining part of the workpiece. Especially in the process of dust addition in the production of plastic molds and precision multi-station progressive molds, good dimensional accuracy can be guaranteed, which directly affects the assembly accuracy of the mold, the accuracy of the zero side ridge parts and the service life of the mold.

Due to the high precision requirements of the machining workpiece, if there is a little negligence in the processing process, the workpiece will be scrapped, and it will also have a negative impact on the manufacturing cost and processing cycle of the mold. For small workpieces with high hardness, high precision and high complexity, and the machining surface is non-planar, it is more important to use the method of multiple cutting to deal with the cutting task of the remaining part of the workpiece.
