February 2015

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.



June, 2015

Replaced another of our Citizen CNC Swiss lathes with a newer model.

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.  This reduces setup time ($cost$) and allows us to reproduce your thread profiles with exacting precision.


September 2014

We have enhanced our ID grinding capability with the addition of a Heald ID grinder. This machine has a grinding stroke of up to 16" (406mm) and a maximum swing of 24.5" (623mm). We have multiple wheel heads capable of speeds up to 38,000rpm.

June 2012

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.

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

Minnesota Grinding, Inc. was recently featured in several different industry trade journals, including Precision Manufacturing, the Journal of the Minnesota Precision Manufacturing Association (MPMA).

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 that electrically transforms the water to clean without chemicals.  Our floors now dry more quickly and our chemical usage has been drastically reduced.  This has resulted in less hazardous wastes released into the environment, a safer workplace, and lower costs.  Learn more about Tennants' innovative technology here:  http://tennantco.com/am-en/Pages/Equipment.aspx


We recently upgraded the lighting system in our manufacturing area, replacing HID lamps and fixtures with high-bay fluorescent fixtures.  The energy used to light our shop has been reduced to 30% of previous levels resulting in an estimated annual (CO2) reduction of 400,323 lbs.

We have also added occupancy sensors to the lighting fixtures to further reduce the energy used.  Rather than lighting an entire bay, only those areas where work is being performed will be lit, resulting in further energy reductions.  As an added bonus, the new lighting produces less heat and will reduce our A/C costs as well.

In 2011 we added several pieces of equipment to our manufacturing area. 

We expanded our Cylindrical grinding capacity by adding 2 used Studer S40 ID/OD grinders and a new Studer S33 ID/OD grinder.


We also increased our Honing capacity with a new Sunnen ML-4000 Power Stroked honing machine.  A power stroking machine assures consistent stoke length and rates and provides better control of bore size and finish.


We added a remanufactured Cincinnati Monoset Tool & Cutter grinder and hopper feed / vibratory bowl system to our CNC centerless grinder.

In our Quality lab, we installed a new Mitutoyo CMM with profiling and statistical software, with touchprobe or vision inputs.


September 2008
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, this machine will soon become a vital resource to the Twin Cities area!

November 2007

cnc cinn 325-2.jpgOur Centerless grinding department recently acquired a Cincinnati 325-12 CNC machine that is capable of plunge (in-feed) grinding multiple diameters simultaneously.  This machine is on-line and producing excellent results!



October 2007

Our CNC Cylindrical grinding department has increased their capabilities and capacity with a Shigiya CNC ID and OD grinder.

Summer 2007

This summer we expanded our Centerless Grinding Department by adding 6,500 sq. feet to our manufacturing space. The first machine to be placed in the space will be a twin-head heavy-duty Centerless grinder with a total of 150 horsepower. This machine is capable of removing large amounts of material from large rollers or bar stock.
