Centerless grinding, Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material ,"Cylindricity control in precision centerless grinding" by ,, A computer simulation method for investigating the form generation mechanism in the centerless grinding process is described In this work, instantaneous change of the apparent depth of cut during grinding was modeled using absolute coordinate systems The result of the simulation was not affected by the coordinate system (the location of the reference circle center and the radius of the ,Precision Thru, Centerless Grinding Centerless grinding is an OD grinding process It differs from other cylindrical processes in that the workpiece is not mechanically constrained On traditional OD machines, the work is held between centers or chucked and rotated against the faster spinning grinding wheel by an external motor usually located in a workheadCenterless Grinding Design Rules, Centerless Grinding Guidelines: The largest diameter of the workpiece should have the ground surface, if possible This allows through-feed grinding The axial length of a centerless-ground workpiece should be at least equal to the diameter Short workpieces are more susceptible to surfaces that deviate from right circular cylindricityCenterless Grinding: Not Magic! | Modern Machine Shop, Dec 15, 2000· Centerless grinding workblade angles range from 0 to 45 degre For most centerless grinding applications, a top blade angle of 30 degrees seems to provide the best results "The basic rule is the steeper the angle of the blade the faster the rounding ,.
