Added CNC Centerless Grinder

We have added more robotics to our floor, to take on even more capacity. We have also added two CNC centerless grinders in that department to stay ahead of the curve with new capabilities. With an office remodel in the works. We hope to have a Quality Lab more than double current size

CNC Thread Grinder

We took delivery of a Drake CNC Precision Thread grinder with robotic loading capabilities, bringing our total to 7 CNC Precision Thread grinders! We intend to continue to lead the market in CNC Precision Thread grinding capabilities and capacity.

Minnesota Grinding announces enhanced thread grinding capabilities!

We continue to invest in new and upgraded machine tools.  Most recently, we have enhanced our thread grinding department yet again with additional software capabilities in the CNC thread grinders.  These upgrades now allow us to convert your .dxf thread profiles directly into machine code.

LARGE flat lapping machine

We added a 2nd LARGE flat lapping machine. This machine has a 96" rotating table and 4-30" heads.

CNC thread grinders

We recently upgraded the controls on one of our CNC thread grinders to bring it up to date with state-of-the-art functionality.  Soon after that we removed the table and had an expert resurface the mating surfaces and true up the entire machine.


Chemicals Safety is a top priority at Minnesota Grinding, and we utilize a non-skid flooring surface in the shop to reduce falls. To keep that floor clean and dry, we have upgraded our floor scrubber to a Tennant model 5700 XP.  This scrubber uses Tennants' ec H2O technology

New capabilities for large diameter bar stock.

Our newest grinder is on-line.  This twin-head centerless grinder is capable of grinding bars up to 6" diameter. We were so impressed by the performance of this machine, we've nicknamed it the "Hogg'in-stock" Capable of rapidly removing material from large bar stock and tube stock
