Wire EDM machine tool is a kind of electrical machining, mainly used to process molds. The method is to make a molybdenum wire (wire cutting machine) or copper wire (slow wire cutting machine) through the workpiece, through the wire walking mechanism to make it do continuous movement, at the same time on this molybdenum wire or copper wire through the pulse high voltage, it and the workpiece between the spark discharge, ablation metal, and by the wire cutting liquid to take away the metal chips, and form a hole, and then by the CNC equipment through the stepper motor to make the workpiece do a certain shape of feed movement, so that the hole stroke produced by the discharge continuous incision, so that the processing is carried out until the end of processing. Wire cutting is characterized by the ability to process complex shapes, high machining accuracy, and small machining deformation, which can be applied to processing hardened steel and cemented carbide workpieces, and the machining process is automated.

The better ones in the field of wire walking are several companies such as Suzhou Baoma.

Before processing, prepare the workpiece material, pressing plate, fixture, and other clamping tools. If you need to cut the workpiece with the shape of the inner cavity, the workpiece should be pre-punched with a wire hole, and then follow the following steps: close the power switch of the machine tool and press the machine start button.

It can process any difficult-to-process metal materials and conductive materials, because the removal of materials in processing is achieved by the electrical and thermal action during discharge, and the machinability of materials mainly depends on the conductivity and thermal properties of the materials, such as melting point, boiling point, specific heat capacity, and thermal conductivity.

resistivity, etc. <>

Features: EDM does not touch the processing tool electrode and the workpiece is not in direct contact, but there is a spark discharge gap, this gap is generally in between, sometimes it may reach even larger, the gap is filled with working fluid, and the workpiece is discharged by high-voltage pulse during processing.

It can be "overcome rigidity with softness" because the electric cracking by-spark processing directly uses electrical energy and heat energy to remove metal materials, which has little to do with the strength and hardness of the workpiece material, so it can be used to process hard workpieces with soft tool electrodes to achieve "overcoming rigidity with softness".

Not a concept. EDM machine tools are specifically divided into EDM forming machine tools and EDM wire cutting machine tools. The processing principle of the two is the same, both of which use the current positive and negative electrode contact discharge to produce high temperature to melt the metal, so as to achieve the purpose of cutting.

Wire cutting machine tools are divided into fast wire walking and slow wire walking. As the name suggests, it is distinguished by the speed of the electrode wire movement. Fast walking wire is generally used as an electrode wire for recycling. The processing efficiency is relatively high, and the accuracy is low.

Copper wire is used as the electrode wire, which has low processing efficiency and high precision, and generally needs to be cut 3-4 times. High processing costs. Wire EDM uses electrode wires to reciprocate and cut parts like a saw. The disadvantage is that only parts that are connected up and down can be machined.

In EDM, the EDM process is called wire EDM by using a wire, an electrode (molybdenum wire or copper wire), as well as the relative motion and discharge between the electrode and the workpiece.

Summary. The main production of wire EDM machine tools in China is wire EDM machine tools, which is a kind of machine tool used to cut metal materials, and the cutting function is achieved through wire EDM. It has the advantages of high cutting precision, fast cutting speed, cutting ***, simple operation, etc., and is a very ideal metal cutting machine tool.

China's main production of EDM wire cutting machine tool is EDM wire cutting machine tool, it is a kind of posture and ambush machine tool used to cut metal materials, through EDM wire cutting to achieve cutting work and energy.

Fellow, I really didn't understand, I can be more specific.

China's main production of EDM wire cutting machine tool is a kind of machine tool for metal cutting, it uses EDM wire cutting technology, can achieve high-speed cutting of metal materials. During the use of EDM wire cutting machine tools, some problems may occur, such as low cutting accuracy, slow cutting speed, high cutting noise, etc. The reasons for these problems may be due to the unreasonable structural design of the machine tool, improper setting of cutting parameters, serious tool wear, etc.

To solve these problems, we must first check whether the structural design of the machine tool is reasonable to ensure the accuracy and stability of the machine tool; Secondly, the cutting parameters should be reasonably set according to the performance of the material and the cutting requirements; Finally, it is necessary to regularly check the wear and tear of the tool and replace it with a new one in time. Personal tip: When using the EDM wire EDM machine, pay attention to the structural design, cutting parameter setting and tool wear of the Hunacha machine to ensure the normal use of the machine.

<> steps of wire EDM processingWire EDM processing is a technology to realize the size processing of workpieces. Under certain equipment conditions, the reasonable formulation of processing process route is an important link to ensure the quality of workpiece processing.

The process of EDM wire cutting to process molds or parts can generally be divided into the following steps.

Analysis and review of drawings Analyzing drawings is the first decisive step to ensure the processing quality of the workpiece and the comprehensive technical indicators of the workpiece. Taking the punching die as an example, when digesting the pattern, it is necessary to first pick out the workpiece pattern that cannot or is not easy to be processed by wire cutting with EDM, which is roughly as follows: The surface roughness and dimensional accuracy of the peib are very high, and the workpiece cannot be manually ground after cutting; Workpieces with narrow slits smaller than the diameter of the electrode wire plus discharge gap, or workpieces with rounded corners formed by the discharge gap of the electrode rigid derrick are not allowed at the corners of the graphic; non-conductive materials; Parts with a thickness exceeding the span of the wire frame; The processing length exceeds the effective stroke length of the x,y carriage and the workpiece with high precision requirements.

Under the condition of conforming to the wire cutting processing technology, careful consideration should be given to the surface roughness, dimensional accuracy, workpiece thickness, workpiece material, size, mating clearance and thickness of the stamping part.
