Cutter Tools

Just as in our machines, there are more than 20 years of experience going in to our LUTZ cutter tools. We always strive to achieve an optimum of the most disparate requirements. Ideally, cutters should:

• remove as little material from the cap as possible,
• keep the shavings as small as possible in order to insure the blower doesn’t clog
• cleaning the cap geometry free of residues, i.e. flanks and the weld point,
• be adapted to the widest range of weld gun pressures during the milling process.

The points named above are a few of the important criteria. Many more proceed from individual customer requirements. In dialogue with users, we have developed to date more than 650 milling tools, many of them custom-fit to the individual guns and cap geometries. Generally, we distinguish between 3 groups of cutter tools:

• single-blade cutters: Most widely distributed, cost effective, useable to 1.5kN clamping force
• single-blade chip breakers: Designed for uses in which more than 1.5 kN clamping force occurs
• Quattro blade cutter tool: Specially suited for low material removal and for uses in which error tolerance with respect to incorrect positioning is necessary.

The first 2 products mentioned especially are available for machines from other manufacturers. Consequently, the customer does not have to change their entire machine stock in order to have the opportunity to use titanium coated cutting blades in LUTZ cutter tools.
