AUTOMATIC RECESSING MACHINE
Area of Application
The automatic CMU is designed for the precise and efficient
grinding/polishing of concave and convex shaped parts (watchjewels,
industrial-jewels, lenses for watch glasses and wearing
parts made out of hard materials such as sapphire, ruby,
ceramics, tungsten carbide, ..
Machine Description
The machine has up to three independent production units mounted on the same base. Each of these units is
separately driven and controlled. They are centrally lubricated and supplied with coolant as well as vacuum required
to automatically handle the parts. Each unit’s handling system uses two vacuum nozzles, one for loading and one for
unloading.
An automatic parts measuring system and a tool-setting device checks each individual parts after machining and if
required, adjusts the diamond tools wear (compensation). The diamond tool is a diamond grinding “pin” or “tube”.
The units operate automatically controlled by a cam shaft mechanism. It is a fully automatic process, including a
parts counter – so to speak.
