PGI is proud to have one of the largest grinding capacities in the United States.
Steel grinding is a process that moves a grinding wheel or segment in a plane while the wheel contacts the work piece and removes material to create a flat surface. Parts may require surface grinding for several reasons, including:
- Flat surface is required
- Accurate thickness tolerance is needed
- Smooth surface finish is required
- Need to remove material from very hard materials
- Quicker material removal
Grinding is a good application for: table tops, robot risers, jigs and fixtures, bolster plates, die shoes, or any part that requires a close tolerance.

What is Vertical Spindle Grinding (also known as Blanchard Grinding)?
The face of a wheel or segmented wheel is used on the flat surface. Vertical spindle grinding (or Blanchard grinding) is often used for fast material removal, and these machines can also accomplish high-precision work. The work piece is held on a reciprocating table or a rotary-table machine.
What is Horizontal Spindle Grinding?
The periphery (outside diameter) of the wheel is in contact with the work piece, producing the flat surface. Horizontal spindle grinding is used in high-precision work on simple flat surfaces, flat surfaces next to shoulders, and recessed surfaces.
