I.Performance
The
pure rotation is Obtained through the differenlial rolling speeds of
the left and right guide pulleys.The clutching power and accuracy of
the pulIey 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.
------Adodtion of PC control
------DigitaI display of the infnite speed and frequency variation of
the left andriht guide pulleys
------Automatic compensation and rectifcation 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-T5801-92
