Hydraulic Cylindrical & Internal Grinding Machine

Hydraulic Cylindrical & Internal Grinding Machine:



Base & Guide Ways

The
base is made of close grained and heavily ribbed casting for high
rigidity. The hand scraped V-Flat table guide wasy with continuous
lubrication. Longitudinal hand travel of the table is by rack and
pinion Gear box arrangemetn and automatic travel by hydraulic mechanism.



Hydraulic System

It consist of hydraulic Pump, Valves, Livers, Piping etc. and all conveniently housed in the base



Wheel Head

The
wheel head spindle is made of case hardened Nickel chrome alloy steel
grounded and microfinished and runs in adjustable while metal bush
bearings to achieve high accuracy and long life. Drive to the wheel
head is transmitted by two 'V' belts.



Work Head

Workhead
spindle is made of case hardened Nickel chrome alloy steel and runs in
angular contact bearing. The drive to the workhead is uitl for
stationery and live spindle grinding. The workhead can be swivelled for
angular grindings.



Tail Stock

The hardned and grounded tall staock spindle is adjustable and spring loaded.



Internal Grinding Head (Optional)

The
unit with its independent drive motor is hinged on the wheel head and
can be quickly lowered into grinding position easily. The internal
Grinding Spindle runs in two precision matchpair angular contact
bearings. The drive to the spindle is transmitted by Flat belt.
