I¡¢Performance
This
machine tool adopls lhe open type batch pan and the batch pan can be
adjusted with frequency conversion.The¡°V¡±locating piece and the round
guide rail adopt hard alloy,resulting in long service life.It also has
an arching to achieve the three¡ªpoint fixwhile griding,thus having improved
the precision of work pieces.The accessories of the feeding support
are alsO provided so as to realize automatic feeding once the accessoriesare
interlinkedwith the hoisting machine£®
-------The speed of the grinding wheel heads can be adjusted
with the frequency converter£®
-------The grnding head feeding can be performed manuallyor hydraulically
inched£®
-------The axle house of the wheel head adopts the¡°V¡±slippage£®A
kingpin is used on the top so as to keep constant stabilized condition
of the abrasion wheel.
-------The main axle of the wheel head adopts high precision
bearings with oil fog Iubrication so as to realize non¡ªstop run without
heating the wheel head and to ensure the precision stability of the
machine tool.
-------The horizontal and vertical adjustment of the wheel head
adopts the three¡ªpoint fix .The value can be read directly from the
indicator£®
-------An osciating¡ªarm trimmer is applied.It is controled by
the straight line cylinder and can be divided into two processes of
fine and coarse trimming£®
-------The hydraulic unit is independent so as to increase the
stability and precision of the machine tool.
