From the analysis of the working principle and working environment of the guide wheel assembly, we can have actual reference value for keeping the wire cutting machine in a good state of machining surface roughness. Let’s start with the structure of the guide wheel assembly. Whether it is a fast wire feeder or a middle wire feeder modified on the basis of the fast wire feeder structure, the guide wheel assembly is divided into two parts: “main pulley assembly” and “auxiliary guide wheel assembly”. Whether it is the main pulley assembly or the auxiliary pulley assembly, it is composed of the following main components: Guide roller sleeve, guide roller, bearing, sleeve, nut

In the metal processing and manufacturing industry, everyone should be familiar with slow wire processing and medium wire processing. They all refer to wire EDM machines, which are widely used in the mold manufacturing industry. So what is the difference between these two processing techniques?

Dear, although the medium wire cutting is not as delicate as the slow wire cutting, it is not as rough as the fast wire cutting. The working environment of wire cutting; wire cutting machine tools are not suitable for working in dirty and high temperature and humid environments (although constant temperature is not required), and there are also high requirements for the power supply environment of the grid. The power supply voltage fluctuation of wire cutting machine tools cannot exceed ±10%. And the three-phase must be balanced and stable, and the power grid that is too bad must be equipped with a voltage regulator; in addition to the normal maintenance of cleanliness and lubrication, the wire cutting machine must also maintain several parts carefully.

The middle wire is also a kind of wire EDM machine. The working principle is to use the continuously moving molybdenum wire (called the electrode wire) as the electrode to perform pulse spark discharge on the workpiece to remove metal and cut into shape. The quality of the processed workpiece is between the two, so it is called the middle wire. To be precise: the middle wire is an upgraded product of the fast wire. It can be understood as: the fast wire that can be cut many times, but its processing and cutting speed is not faster than the fast wire. The wire is slow, but it is higher than the fast wire. Only in the process of multiple cutting, the cutting speed can be reduced to achieve the cutting effect. At this time, the average efficiency is calculated, not the highest efficiency, and the processing quality tends to be slow. Silk. The wire running speed is automatically controlled by the system and can be adjusted as needed.

Taper device is one of the key components and core technologies of CNC wire cutting machine tools. With the wire-feeding machine products The continuous upgrading of tapered cutting accuracy has put forward higher requirements. Therefore, a high-precision taper device is designed, which solves the problems of rigidity, reliability, transmission accuracy and protection from the structural performance. Through application and verification, its geometric accuracy and numerical control motion accuracy have been steadily improved, and it can complete the processing of high-precision taper cutting and multiple cutting.
