Product Details

The MODEL 80 possesses high precision, quality and maintenance free design . It accommodated grinding of cylindrical, tapered and blind holes. It can be proved blessing for mass production industries, i.e. Antifriction Bearings, Tractors, Scooters, Automobiles, their spares and Defense etc. The technical characteristics as given below well tell the rest

MODE OF OPERATION

Fully automatic cycle with manual loading and unloading of the component .The grinding cycle is controlled with electro-hydraulic valve sequence . Any one of the following cycles can be chosen by the selector switch and a cam limit switch. The automatic cycle (Interval dressing , pre-dressing and skip dressing cycle) of the machine is as follows.

By setting the counter value at 0004 ,this cycle will be operated 4 times without dressing . More –over any one of the above cycle can be selected to be operated once only with dressing.

* CLEANING OF GRINDING WHEEL AT ONE SIDE (RIGHT TO LEFT)

* * CLEANING OF GRINDING WHEEL BOTH THE SIDES (RIGHT TO LEFT & LEFT TO RIGHT)

DISTINCTIVE FEATURES OF MODEL 80 INTERNAL GRINDER

Highest quality stress relieved castings ensure great rigidity and prolonged accuracy.
Tow tables ( i.e. longitudinal table and feed table) mounted on hardened prisms and prestressed rollers .
Work spindle running in special high precision HG or P4 class bearings.

Grinding wheel head mounted on longitudinal table without cross slide, ensuring maximum rigidity.
Entire machine is lubricated by oil mist .
Variety of belt driven spindle .Changes over of the spindle is easy and less time consuming . Maintenance of this spindle is easy.
( Optional : Oil mist lubrication belt driven spindle {Integral motor construction} )
Extra sensitive feed control permitting separate progressive adjustment of roughing and finishing feed.
Possibility to equip the machine with an electronic sizing device for direct measurement during grinding .
Oversize electrical equipment mounted in a control cabinet and hydraulic power pack separate from the machine eliminating vibration and thermal distortion.
Any one of the cycles can be chosen by selector switch and can limit switch.
Programmable logic controller (PLC) along with high precision limit switches makes operation more accurate.
There are many more special accessories like True chuck, Diaphragm Chuck and shock-centreless chuck ( magnetic )
