Opinion on Surface Grinder

I am of the opinion that a machine should be left in place. In the case of a surface grinder you are asking a machine to work in tenths of a thousandth. It would seem to me that moving it around would jeopardize its accuracy.

In terms of power feed my grinder is 3 phase and I am using a static phase converter. While I believe a VFD would be a better choice this set up has served me well. Just another opinion.
 
A Surface Grinder is a precision machine tool that requires special attention to a few details. The following assumes the machine is in good condition and capable of grinding to less than .001 inch.

First clean up the machine and lubricate it using proper spindle oil and way lube. Do not dissemble the spindle. Complete any maintenence needed as well as refurb's painting etc. necessary or desired.

1) Make or Buy leveling feet with rubber isolation pads on them.

2) Install feet into the cabinate base and course adjust to a ruler setting.
3) Move the machine to its permanent home, NO CASTERS.
The location needs to consider which way grit will exit the wheel. If your oily lathe or milling machine is down wind, it will soon be covered with abrasive grit that will drastically shorted their life.
4) Place a precision machine level on the chuck and adjust the feet to bring it level. Let the machine set for a few days and repeat leveling now that the rubber has settled under the machine weight. During the second leveling, also note the torque on the wrench required to adjust the leveling feet. It is important to have the feet carrying equal load to prevent rocking.

The rubber isolates vibration that may effect surface finish.

After the leveling is complete accuracy testing may start.

Good luck and enjoy!
