Our CNC External Grinding Capabilities

Okuma GU-35S universal CNC external grinding machine — CNC external grinding Michigan at Joint Production Technology

JPT operates advanced CNC external grinding equipment capable of producing precise outside diameters, cylindricity, and surface finish in hardened steel, carbide, and a wide range of engineering materials. Our external grinding services include cylindrical OD grinding, taper grinding, and form grinding.

Why Choose JPT for External Grinding

With over 50 years of precision grinding experience, JPT delivers OD tolerances and surface finishes that meet the most demanding customer specifications. Our engineering team works with customers to optimize grinding cycles and ensure consistent results across both short-run and high-volume production.

JPT external grinding services support automotive and diesel drivetrain components, aerospace structural parts, defense system components, and medical device manufacturing. All ground parts are inspected using our CMM measurement systems to verify dimensional accuracy and compliance.

JPT’s O.D. grinding may be performed by both straight-approach or angle-approach grinding wheels and can be combined with I.D. grinding in one continuous CNC cycle.

JPT’s CNC external grinding Michigan capabilities handle both straight-approach and angle-approach grinding wheels and can combine OD and ID grinding in one continuous CNC cycle. Single setup production to very close tolerances is achieved without handling the part during grinding. Accuracy is verified by a touch probe cycle that measures the OD after grinding.

    The JPT Way

    Most tooling problems aren’t solved by buying off the shelf. They’re solved by understanding the application, the machine, and the process — then engineering the right solution.

    Cutting tools. Fixturing. Complete production solutions. That’s been the JPT way since 1971. No catalogs. No guessing. Just engineering.
