Tightest tolerances and finest surfaces – also contactless if required.
Additional grinding & eroding process
Our additional processes grinding and eroding complement the CNC spectrum of Wefo-Tec. This is how we realize the tightest tolerances and finest surfaces – economically, reliably and documented.
With the surface grinding (pendulum grinding) the grinding wheel oscillates over the workpiece at high speed. This process is ideal for flat surfaces with minimal dimensional, shape and position tolerances.
The eroding – whether wire-cutting or die-sinking – is used when conventional processes reach their limits. Conductive materials such as aluminum, steel, copper or brass are processed contactless and with minimal thermal influence. This ensures virtually free shaping.
Our highly qualified specialists combine many years of experience in handling their machines and materials with integrated CAD/CAM processes. This enables us to fulfill even complex tasks in mechanical engineering, automotive and electrical the highest standards of precision, repeat accuracy and documentation.

Surface grinding
The surface grindingalso known as pendulum, surface or peripheral grinding, is used at Wefo-Tec specifically for the highest surface requirements. The grinding wheel moves back and forth over the workpiece at a high feed rate and removes material during both movements – in synchronous and counter-rotation.
This process produces flat surfaces with the finest surface quality and minimal dimensional, shape and position tolerances. This makes surface grinding ideal for components that require maximum precision and repeat accuracy.

Eroding
The eroding is a high-precision process for machining electrically conductive materials such as aluminum, copper, brass or steel. In this process, the material is electrical discharges (spark erosion) without any mechanical contact.
The big advantage: even complex geometries and tight tolerances can be realized with minimal thermal impact on the surrounding material. This is why we at Wefo-Tec use EDM wherever conventional processes reach their limits.
Whether wire erosion for the finest contours or die-sinking EDM for exact shapes – our modern 4- and 5-axis systems in Markt Erlbach enable precise, economical and documented production for customers in the mechanical engineering, automotive and electrical industries.
Wire erosion & die sinking
The two most common processes in the field of eroding are the wire erosion and die sinking die sinking.
When wire erosion uses an extremely thin electrode in wire form – with a diameter of less than 0.5 mm. This allows even the finest contours to be produced with the highest precision.
When die sinking the electrode reproduces the exact shape of the desired tool and transfers it precisely to the workpiece.
At Wefo-Tec we use modern modern 5-axis machines for wire EDM and for die sinking for die-sinking and high-performance 4-axis machines for die-sinking. This enables us to produce even complex geometries reliably and economically – documented and with repeat accuracy.

Eroding – precise, contactless and accurate
When maximum precision, intricate geometries and tight tolerances are required, eroding comes into play. At Wefo-Tec, you get high-performance eroding – with state-of-the-art technology, a continuous process chain and experienced specialists. We machine conductive materials without contact and with virtually no thermal influence – ideal for complex components in individual or small series production.
Wire EDM & die sinking from a single source
In wire EDM, we use a thin wire electrode with which even the finest contours can be precisely reproduced. A shaped electrode is used for die-sinking EDM processes, which enables ideal results for internal contours and cavities. Both processes offer maximum dimensional accuracy – without mechanical tool contact.
