Introduction of precision machinery parts EDM processing

As we all know, EDM is widely used in the mold and mechanical processing industry. It is specially used to process superhard materials and complex shaped workpieces that cannot be processed by traditional cutting methods. Today, Yize mould will introduce the processing skills of precision machinery parts EDM processing.

A: Shaking mode
1. Swing round, electrode has inner R. generally, shake round (depending on the clearance of electrode diagram R)

2. Generally speaking, in most cases, the spark position of R and C angles of electrodes is swing from 0.01 to 0.02

3. At the same time, h018 = 303 is changed to 403 when the drawing requires corner cleaning

B: Undercutting processing

The z-axis machining is locked in the general program (i.e. h018 = 303 changed to 203) or manual program is used as follows:
1. C004 (processing conditions)
2. G0xyz3.0 (displacement)
3. G01z-20.0 (machining depth)
4. X + 0.5 (side clearance) g02i-0.5 (side clearance, "I" letter I is not number 1)
5、G01XY

6、G0Z3.0 M02

C:Slope machining
The side or bottom surface of the electrode has a slope, no matter which size is increased, the size of an axis associated with it will change. It is necessary to use trigonometric function calculation or CAD drawing to draw it.

D:Measurement method
Generally, the altimeter measurement is preferred. The focus error should be paid attention to in the projection of the display. The dimension can be adjusted only when Z axis of the same height is unchanged. If the z-axis is shaken up and down, it is necessary to find the auxiliary surface with the same height of the measuring surface for proofreading, or find the datum plane to measure again on the measured surface (pay attention to the tolerance).

The above is the processing skills of precision machinery parts EDM processing summarized by Yize. Precision machinery equipment parts processing,choose Dongguan yize mould.Yize mold with years of professional knowledge and unique manufacturing breadth and production depth, provides customers with a wide range of precision machining technical support, including turning, milling, plane, circular, grinding, spark discharge In addition, we can design and assemble complete sets of mechanical components and mold components according to customer requirements.
