Centerless grinding machines

JUNKER centerless machines are ideal for grinding large quantities in the shortest possible time. Easy installation and changeover guarantee flexible adjustment to market requirements. The JUPITER production machines impress with their sophisticated overall concept and high level of productivity.

The large feed and matchless workpiece support facilitate high removal rates and therefore high output volumes. During centerless cylindrical grinding, the workpiece is not clamped but lies in the gap between the grinding wheel, regulating wheel and workrest blade. The patented CNC height adjustment of the workrest blade minimizes tooling times, while automatic adjustment of the grinding gap geometry optimizes the grinding process. The inclined bed also guarantees maximum dimensional accuracy.


Centerless grinding machines use external cylindrical grinding in throughfeed grinding, plunge-cut and angular plunge-cut grinding. An application may require corundum, CBN or diamond as an abrasive. The workpieces machined on JUNKER centerless grinding machines range from roller bearing parts (such as rollers, needles, cages and rings) to shafts (gear, turbocharger or rotor shafts) and all engine components, such as camshaft tubes, valves or wrist pins.
