CERATIZIT develops the new MaxiMill HPC 12 milling mill with an international team


With its segment strategy in the business unit end-users of the cutting tooling division, the carbide expert CERATIZIT is particularly successful as the company counts on segment-specific and customer-specific products as well as on tailor-made solutions. In this way the global player in the field of advanced carbide solutions also proves its competence in niche markets. International cooperation within the group plays an important role here. An international team developed a unique milling concept for the automotive industry, namely the aluminium cutter MaxiMill HPC 12.

A complete tooling concept in only six months
The starting point of the project was a meeting at an automotive customer’s in July 2003. CERATIZIT made an offer to the professional production manager to deliver new tools which would meet the increased requirements within only six months. An extremely ambitious deadline chosen by CERATIZIT itself. The CERATIZIT project team had an additional goal: a new flexible tooling concept should be developed which would be suitable for the majority of applications in aluminium milling for the automotive industry.

This development project brought the MaxiMill HPC12 concept into being. The idea was to develop a milling concept where the number of teeth, the form of the cutter body, the coolant, the cutting edge geometry, the rake angles and the cutting materials (CBN, PCD) could be modified.

MaxiMill HPC 12 – the properties
Low cutting forces thanks to positive rake angles
Reduced deformation of the components
Reduced built-up edge
Increased tool life
Tool body made of steel
Precise repeatability during industrial insert change
Very high stability and longer tool life
Options: bimetallic version (steel ring and aluminium core).
High speed – high performance
Reduced work piece heating
Maximum productivity
Optimised design of tool and insert industrial seat
Axial fine adjustment
Short setting time through easy handling
Fine adjustment = 0.1 mm
