Up-Grind and tool sharpening service

Tools sharpening can give back to a punch all features as first purchased, but the machine that should be used for regrinding tool is also very important as all our tools (and most of the tool you have in your tool’s inventory) are made of High-Quality Special steel, so you must follows some specific procedures for regrind these tools in a proper way and avoid to damage them.

You must use coolant when grinding, if you do not punch edge would be cracked easily, polishing by hand after grinding is necessary to remove burrs on punch edge that is naturally generated by re-sharpening operation, and always demagnetized the tools before bringing them back to storage.

This machine should be designed specific for punching tool, and it’s mean that should respect some specific criteria for regrind speed, tool coolant and structure.

If we do not sharpen the tools at the right time the performance, already compromised, will get worse and worse without following the increase in radius.
We therefore believe that in order to achieve maximum performance from the tools, we must sharpen when the cutting edge wear radius is about 0.15mm.

Tool life more than doubled when we sharpen them correctly and more often!

A correct sharpening can give the tool back the same characteristics as when we bought it, this is why Rolleri offers a tool sharpening service, to allow everyone to make the most of the potential of their tools.
