Perfect CNC Wire Cut Machine Process-China CNC Wire Cut Machine

Process indexes and parameters of CNC wire cut machine process

Main indexes of CNC wire cut machine process

There are five main indexes of CNC wire cut machine process:cutting speed,cutting accuracy,surface roughness and electrode abrasion volume.

Main influencing factors of CNC wire cut machine process

（1）The process of CNC wire cutting machine is affected by processing parameters,which mainly include:peak current,pulse width,pulse interval,wire walking speed and feed speed.

（2）The process performance of CNCC wire cutting machine is affected by wire electrode wire.The diameter and perpendicularity of electrode wire will affect the process performance.

（3）The material of the workpiece and the thickness of the material will also have an impact on the process index of the CNC wire cutting machine.

（4）The working fluid will also have an impact on the process indexes of CNCwire cutting machine:special emulsion is selected for high-speed wire walking,deionized water is selected for low-speed wire walking;At the same time,the concentration of working fluid is affected by cutting speed,thickness,flow,flow direction,machining accuracy and surface roughness.

Part drawing analysis of CNC wire cut machine process

（1）Clear processing requirements;

（2）Analyze the main positioning datum,correctly locate and clamp,and determine the machining coordinate system;

（3）Rationalization of cutting starting point and processing route;

（4）Mark the places where WEDM cannot be used.

Correct clamping of process workpiece of CNC wire cutting machine

It is necessary to find the correct method and common fixture for the correct clamping of process workpiece of NC wire cutting machine

（1）During workpiece clamping,the datum surface shall be clean and free of burrs,the fixture precision shall be high,and the auxiliary fixture that is not easy to deform shall be used

（2）The production of precision and small workpieces adopts special fixtures to produce.

（3）Clamping mode of workpiece:cantilever,support at both ends,bridge support,plate support and compound support

（4）Adjustment method of workpiece:use dial indicator for alignment and scribe line for alignment.

（5）Correction method of electrode wire perpendicularity:use spark correction method with the help of special correction tools.
