Grinding with High Precision

The regrinding of milling tools and the production of special tools are the business of Metz Metal Cutting Tools. This small, flexible company focuses on quality - in the interests of its customers. 

However, this only applies to the breadth of the product range. Metz sees the company's strengths in the fact that “we deliver quickly, flexibly and in high quality.”

Depending on the tool and customer requirements, the achieved tolerances are in the range of up to ± 1/100 mm. This is not always based on the accuracy required for the cutting process, but on the process, reliability resulting from the use of precise tools.

At Metz, six ISOG 20+ machines with FANUC CNC and software from the Swiss specialist MTS AG are in operation. FANUC’s technology has convinced Metz thanks to short position control cycles and the high resolution of the control system. Qualities that an operator can optimise by experience in the two-dimensional field can only be achieved in simultaneous 5-axis operation, as in tool grinding, by a powerful control system. 

As the machine equipment and user interface are uniform every employee can work on any machine assuring short set-up times and keeping training costs low.

A 3D simulation of the grinding process is indispensable. Metz: "Before we introduce new tool programs, let's take a look at it in 3D." Ideally, the CAD data of any new tool is recorded and adapted. "We do not grind according to a standard program, but actually adapt our work steps to the condition of the tool." This can be done either at a separate programming station or directly at the machine’s CNC. Collision monitoring is essential here.
