Cylindrical Grinding Machine By Shree Vishwakarma Engineering Works

Cylindrical 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.

Coolant
Generous coolant supply is provided with electrical pump fitted on separate tank is of 90 Litrs approx.

Electricals
The
Machine is supplied with all electrical suitable for 400/440 V AC 50
Cycles. The motors are of reputed make. The electrical panel is mounted
on one side of the machine, push button station is located at easy
reach to the operator.
