Centerless grinding method
9.2.1
Thrufeed method
Grinding is made by passing workpiece through two grinding wheels meanwhile.
Regulating wheel is made to an inlcination fora applying its component of velocity
in cirucumferentical speed. To guide workrpiece to the correct grinding position,
four guide plates are placed in front of and rear of blade. Pay attention on
correction of regulating wheel and thanworpiece in line contatct with regulatin
wheel owing to inclinaton of regulating wheel. Only incline regulatig wheel,
workpiece touches regulating wheel on one point. Hence, regulating must be
corrected to dram-line and its corrected device is placed according to the inclinaton.
This method is only suitable for cylindrical workpiece and few different diameters
of workpiece, such as rod, bar, piston pin, needle, bearing retainer and pipe etc. To
go on rough grinding and finishing at tehsametime, serveral sets of grinding
machines are made to a grindig engineering line. Bar feeder, part feeder, ring
feeder and hopper elevator are available to heighten work efficiency.
