Sharpening Machine Blades
and Mill Knives

Shear Blade SharpeningPrecision Grinding, Inc. is known for sharpening machine blades and mill knives for paper mills, plywood mills, steel companies, machine shops, automotive manufacturers, industrial companies and manufacturing companies of all types across every industry, every day, and we’d like to do business with you.

At times, supporting steel shims may be required to return your shears to the original thickness necessary to fit your machine. We will flame cut or plasma cut shims from plate inventory, laser-cut or otherwise scissor-cut roll stock, machine bolt holes when needed, and grind shims when necessary to OEM machine recommended shear size and specifications.

With the support of experienced grinding department personnel and experienced machine shop machinists, you can count on us when you need any size or style blades ground, reworked and refinished to a near new condition and shipped to you on time.

Common names associated with these mill blades include:

  • Machine Cutters
  • Industrial Shear Blades
  • Hydraulic Shears
  • Industrial Knives
  • Slitters
  • Slitter Blades
  • Choppers
  • Rolling Mill Knives


History of PGI Grinding

Precision Grinding, Inc. opened doors in Birmingham, Alabama in 1971 with four grinding machines. Our original business model targeted shear blade sharpening. We’ve been sharpening machine blades and industrial knives for more than 45 years now, and today we’re one of the most recognized blade sharpening companies in the country.

Today, we operate many of the largest Blanchard & Mattison grinders housed within one company in America. Four of our Mattison grinders are for surface grinding machine blades to ± 0.001″ tolerances. Our largest Mattison surface grinder can handle steel parts up to 31″ h x 37″ x 200″.
