2. SELECTION AND PREPARATION OF RIGHT PLACE
FOR GRINDING OPERATION
The efficiency of the machine and the precision of the ground surface
of the work piece parts depend largely on the operation site of the machine.
So the careful selection of the place is very important.
Make sure the machine will not be placed close to the quenching furnace or
oil bath. Otherwise chemical gases from them can damage the electricals
of the machine. The ideal place for the Mitsui Surface Grinder is
ventilated room, air conditioned to the temperature of 20 degrees centigrade
(68 degrees Fuhrenheit). The concrete floor 1-1/4" thick or more preferably can be
strong enough to bear the weight of machine where the influence
of the vibration causing machine such as presses is negligible.
1. Vibrationless locality
Select in all cases a vibrationless locality and avoid immediate neighborhood of
large machines such as press machines.
Problems or faulty operations, caused due to the wrong location of the machine
placed in between vibration-causing-machines, seem not to be recognized by many
users. Grinders set in such locality can produce chatter marks on the ground
surface, but many users regard this to be caused by the spindle and adjust
it, resulting in the unusable spindle.
Where the circumstances do not allow ideal place, make sure the concrete floor
will be no less than 10" thick (Refer to Fig.1).
2. No fluctuation of temperature
For the best performance the room temperature should be maintained at 20
degrees centigrade (68 degrees Fuhrenheit) all the time.
To o great variation of the temperature can cause the distortion and disturb
precision of the machine, because larger machine parts (frame, slides, grinding
heads. etc.) can not follow the temperature variation as fast as the smaller
parts. It is also important to have the machine not exposed directly to the sun
light.
3. Floor space requirements
Floor space required for each machine is shown in Fig.2, next page.
Note the positions of the leveling saucers for installation of the machine.
