Grinding Services

The services below are just some of the few services we provide


Type: Thrufeed & Infeed grinding 
Recommended For: Cylindrical parts
Material Type: Ferrous and non-ferrous material

For grinding bar stock, there is almost nothing that matches up to centerless grinding. Using an abrasive material, such as polycrystalline diamond and cubic boron nitride, we can remove material without deformation. We offer high precision Thrufeed and Infeed centerless grinding for workpieces. With Thrufeed centerless grinding, we are able to work with workpieces with consistent roundness in the length of the workpiece. In Infeed centerless grinding, Raymac Grinding can grind cylindrical workpieces with complex shapes and/or tapers to stringent tolerances. Whatever the method, we have over 58 years of experience, and can do the job right and on time!

Honing Services

Improves: Out-Of-Roundness, axial distortion, and taper
Recommended For:
High-performance components
Material Type: Ferrous material, non-ferrous material, and other material types

Honing is accomplished by abrasive stones of suitable grit depending on the workpiece characteristic type.  Raymac Grinding uses the highest quality honing stones for the best accuracy and finish. Finishing is done by rotating the proper honing tool against the work surface. The stock removal process takes out any flaked metal and provides the best possible finish pattern. In addition, honing will remove any out-of-roundness, axial distortion, and taper the workpiece may have.

Thread Rolling

Thread Types: Multiple high-quality steel forming dies
Recommended For: Fastener manufacturing
Production: 1 piece - 200,000 + pieces
Knurling For: Medical field, tool handles, and more

Thread Rolling produces precise and uniform external threads on fasteners by using a cold forging process that reshapes stock from ductile ground blanks, forming high tensile and shear strength external threads on the workpiece. For over 58 years, Raymac Grinding has been accommodating knurling services. We provide the best knurling finish from angled and cross line diamond patterns.
Raymac does thread rolling, for bolts, nuts, and other hardware.

TOLERANCE: +/-.001"
RECOMMENDED FOR: Large castings, large sections of plate stock, large stampings and more.
MATERIAL TYPE: Ferrous material, non-ferrous material some plastics and rubber.

Referred to as rotary surface grinding, Blanchard Grinding removes stock from one side of the material. Rotary surface grinding is best suited for large pieces of material, to a tolerance no less than 0.001". For ferrous materials, Raymac Grinding utilizes magnets and we use alternative holding methods for non-ferrous materials. We also due surface grinding on other materials such as plastics and rubber.
