Latest functions of the wire EDM machines

The PEPS wire EDM module is developed in close cooperation with well-known manufacturers of wire EDM machines and is constantly adapted to the latest functions of wire EDM machines in order to meet the increasing demands on wire EDM. Thanks to its extensive functionality, PEPS is the market leader in this area and is recommended by many manufacturers for wire EDM.

PEPS add-on modules for wire EDM

In order to achieve optimisation in all areas of wire EDM, PEPS offers a variety of additional modules. A selection of the most popular additional modules for wire EDM with PEPS can be found here.

The part failure protection automatically creates markings in the cutting plates. During the punching process, these marks prevent the punched part from sticking to the punch and damaging the cutting tool. This significantly increases the service life of cutting tools.

The projection at an angle enables the processing of variable reference heights. Thus, a circumferential cylindrical collar with constant height can be created on the workpiece. The conical area is calculated by PEPS and does not have to be already included in the construction of the 3D model.

PEPS offers the functionality to control additional rotary axes and thus multi-axis machining during wire cutting. Complex workpieces can thus be machined without restriction.

  • Maximum taper angle
  • Maximum accuracy
  • Maximum surface quality
  • Machining of one clamping

Control surface pocket erosion enables the machining of control surfaces without a drop-out part. The programming effort for wire eroding is thus significantly reduced and machining can be carried out unattended.

Partial pocket erosion enables the combination of normal roughing and pocket erosion. It prevents the formation of lost parts during roughing and thus enables unattended and trouble-free operation.

To improve the accuracy of fit between punches and dies, this PEPS macro changes or “manipulates” the radii contained in a geometry.

With partial contour machining, partial areas of a geometry can be machined with different qualities during wire EDM.

The PEPS Turning Steel Module calculates the geometry required for wire EDM of profile turning steels depending on the clamping angle, the frontal clearance angle and the lateral clearance angle on the turning steel.

PEPS zero contour machining is used for the production of industrial diamonds (PCD). Optionally, geometries can be automatically nested. Machining takes place on the specified geometry without radius correction.
