Isn't 2 surface grinders overdoing it just a little? ;-)
I noticed you had 2 vises on the Bridgeport table. Is there a reason, or just storing them there?
What me overdo it?
Why two surface grinders? I use the smaller 8” by 18” surface for smaller grinding jobs and form grinding operations. It is a totally manual grinder that has 1/ 2” wide by 7” diameter wheel. Because of its' size, it's handier to use on smaller workpieces. Although it is setup for wet grinding, I never use coolant on this machine.
My larger grinder is fully automatic and has flood coolant that keeps the workpiece from heating up and distorting. And having a 1” wide by 12” diameter wheel, it can remove more stock faster. Has a larger capacity and can grind a 10” by 20” surface flat. While having the capability of running automatically, it frees me up to do other chores around the shop.
Here's a small video clip of the larger grinder running.
The vice under the Bridgeport spindle is clamped to the table and is normally used on that machine. The larger Kearney Trecker vice to its' left is just resting there while I have something else set up the Kearney Trecker.
Here's a small video clip of that vice in use on the Kearney Trecker Rotary Head Mill. I'm cutting a 3.00" outside diameter channel 5/8" wide and taking a depth cut of .040". To a finished depth of 3/ 4". That will take about 20 circular passes. The head takes about 30 seconds to complete its’ circular path. And about ten minutes to complete the channel. The blue hose is used to blow the chips out of the cutter’s path. The mill has an air pump as standard equipment.
