Simulation of plunge centerless grinding processes

Nov 21, 2007 · Workpiece out-of-roundness is one of the most important problems in centerless grinding. Besides geometrical and kinematical effects, the dynamical behavior of the machine structure, the grinding and regulating wheel together with the support blade fundamentally influence the process stability and the workpiece accuracy.

Centerless grinding machines JUNKER Group

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.

cDD Dresser Case Study Centerless Grinding with SiC Wheel

Mar 20, 2013 · A Fuel Injection customer recently approached Meister to improve the dressing operation for a centerless plunge-grinding application. The parts were injection needles and the customer was using a green SiC (Silicon Carbide) wheel for the job. They were using a hand-set diamond dressing disk with defined corner radii along with the CNC control of the machine to create the desired profile in the wheel.

Centerless Grinding

In grinding, the wheel follows a simple path. For example, in plunge grinding a shaft, the wheel moves in towards the axis of the part, grinds it, and then moves back out. Since each slice of the wheel repeatedly contacts the same slice of the workpiece, any inaccuracies in the geometric shape of the grinding wheel will be transferred onto the
