Abstract (en)
[origin: EP2006052A1] The emery wheel grinding machine with adjustable drill bit chuck disclosed herein has an adjustable chuck in which is provided with a T-bushing having an outer flange formed at one end thereof. The outer flange is provided with several pairs of stop traps along its circumference, whereas the number of stop traps are determined according to number of cutter blades to be shaved. Several stop pins are formed on the surface of the outer flange to control the turning angle of the drill bit or the cutter. The T-bushing further has a taper hole in it. When the chuck head which holds the drill bit or the cutter is inserted into the taper hole, the cutter blade can be in contact with the emery wheel with a certain tilted angle thereby allowing the cutter blades of various length and number to be effectively shaved, ground and finished.
