MODEL 80
INTERNAL CYLINDRICAL GRINDERS

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 Defence 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 choosen 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 .
• Workspindle running in special high precision HG or P4 class bearings.

• Grinding wheelhead 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 premitting separate prograssive 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 choosen by selector switch and can limit switch.
• Programmable logic controller (PLC) alongwith high precision limit switches makes operation more accurate.
• There are many more special accessories like True chuck, Diaphragm Chuck and shoc-centreless chuck ( megnetic )
