Measures and Controls


The instant in which the grinding wheel comes into contact with the workpiece, is important :

  • To reduce the cycle time
  • To minimize the ‘gap’ time, maximising the feeds of the axis.

The analysis of the contact between grinding wheel-dresser, consents to obtain a perfect profile and optimise the scrap.
The grinding machines may be equipped with measuring systems to:

  • Detect sub-micron contacts (gap control)
  • Monitor constantly the work to prevent collision (anti-crash)
  • Generate feedback signals for adaptive control actions

Grinding Wheel Balancing

Continuously monitors the machine conditions and in in real time compensates eventual grinding wheel umbalance.
Grinding wheel balancing

  • improves the mechanical stability of the grinding machine
  • improves the surface quality of each piece, avoiding risks of facets , roundness errors and defects of roughness
  • allows to increase the peripheral speed of the grinding wheel and the cutting
  • increases the quantity of ground workpieces
  • reduces stress on the spindle bearings

Workpiece setting

The use of a flagging device connected to the PLC control records the position of the workpiece in Z axis (table).

In-process measurement

The use of measuring systems during the working, permits to grind components with high restricted tolerance.
The available methods are :

  • Absolute measurement of diameters,with large ranges
  • Measurement of small and large ranges, with reference master
  • Control of continuous and interrupted surfaces (regular and irregular)
  • Analysis of roundness and shape
  • Measurement of the diameters: external, internal, thickness, taper, shoulder, etc.
  • Automatic compensation of the in-process correction.
