3MMT4320A SERIES PRECISION NONMAGNETIC CONICAL ROLLER SPHERICAL TAPERED FACE GRINDING MACHINE
I£®
Performance Abstract
The pure rotation is obtained through the differential rolling speeds of the left and right guide pulleys. The clutching power and accuracy of the pulley have assured an excellent precision and roughness of the work pieces. By means of nonmagnetic grinding, the problems relating to the magnetic residue have been properly solved. Rough grinding and precision grinding can be completed in one continuous process of the machine thus enhancing the productivity greatly.
Adoption of PC control
Digital display of the infinite speed and frequency variation of the left and right guide pulleys.
Automatic compensation and rectification of the grinding wheels
Automatic count of work pieces and error display of the machine.
II.Machining Precision
The accuracy of the work pieces meets the Grade II standards of JB-T58001-92
