The Centerless Grinding throughfeed and plunge
Grinding of turned parts is a machining technique that consists of machining mechanical parts to improve their precision and/or surface finish.
Different types of grinding can be used depending on the characteristics and shape of the part to be ground.
SA Lefaillet performs all these types of grinding, and in particular centreless grinding, whether throughfeed or plunge.
Centerless throughfeed and plunge grinding
Centerless grinding is a cylindrical grinding process in which the workpiece is not held between centers, but is placed on a slide and rotated between two grinding wheels whose position remains fixed.
Centerless grinding is referred to as:
- Throughfeed, when the workpiece moves axially between the two grinding wheels.
- Plunging, when there is no axial movement.
Main materials used in centerless grinding
The main materials used in centerless grinding at Lefaillet are the following:
- Rossi machines.
- Traditional Ghiringhelli and CNC machines.
