Gear machining with EHWA CBN/diamond grinding and honing tools

A gearbox (or converter element) is a machine element with which movement variables can be changed. The requirements for a gearbox are higher than ever, especially in terms of mechanical load capacity and compact design.

Due to these high requirements, the surfaces and flanks of a gear must be ground particularly precisely and quickly.

For years, EHWA has been supplying the automotive industry with special bindings that work highly efficiently and save you high tool costs.
