Precision Grinding, Inc. specializes in flame cutting, Blanchard
machining steel plate products.
Cutting, Grinding, Machining
A bolster plate normally has t-slots or scribed lines running in
parallel the length of the plate. There are many variations
in size, dimension, and functionality for these plates.
Engineers and tool makers custom design bolsters to meet
These plates are normally thicker than 2". We flame cut, then
stress relieve A36 structural plate in order to improve the
grinding and machining processes. Though, often times
specifications suggest a Blanchard ground to ± 0.005" tolerance
thickness and a ± 0.005 - 0.010" parallelism tolerance, relaxing
tolerance levels may save time and money. Of course, critical,
close tolerances can also be achieved. Please, always inform us
of your grinding tolerance needs.
CNC Vertical Machining Centers
Our precision machine shop runs two large CNC Machines. Max
capacity for our Takumi CNC Machine is 31"h x 78" x
122" at 22,000 lbs. Our CNC machinists average over 5 years experience at Precision Grinding. Our resident
are capable of assisting in design engineering, CAD Programming, and full CNC operations. Many of our veteran machinists have been working
with Precision Grinding for over 20 years.
Most of these plates require a high-level of expertise when
it comes to finishing reamed holes, cutting grooves, beveling or chamfering edges, and end milling or face milling. We can also provide a detailed inspection report
