Tool inspection and maintenance on CNC grinding machines

Regular inspection and maintenance of tools are decisive for safe work and consistent quality on CNC grinding machines. The most important points:

1. Before starting work: Check all tool components for proper condition. Check the position of the handwheels and levers, check the rapid feed for friction and ensure that the limit switches fulfil their protective function.
2. When starting: When starting each time, make sure that tools and handwheels are in the intended working position. Operate the rapid feed lever gently at first to check the direction and position of movement – never jerkily.
3. Cleaning: Tool holders, brackets, spacer rings, dividing heads, vices and bore holders must be clean. Keep the machine free of dirt and deposits.
4. Before starting: Check that the tools are clamped firmly and the workpieces are held securely. Clamping plates must lie flat; do not choose supports under clamping plates too high or too numerous. Do not misuse spacer rings and check them for parallelism before use.
5. During operation: Always stop the machine for workpiece changes, tool changes, clamping, setting, speed changes and measuring. When changing tool holders, milling cutters or chucks, first stop the drive and relieve the clamping device – avoid accidents and tool damage.

Conclusion: Short, regular checks prevent costly breakdowns and protect your employees. Those who observe the five golden rules of tool care work safely, precisely and economically.
