Buy OD Grinding Services Manufacturer & Custom Precision Parts

Yes. Custom precision carbide parts represent over 70% of our production volume. Submit your 2D drawings (DWG, DXF, PDF) and 3D CAD models (STEP, IGES). Our metallurgical engineering team verifies dimensional tolerances, recommends optimal tungsten carbide grades, and reviews sintering shrink ratios within 8 business hours.

Our CNC cylindrical and centerless OD grinding machines achieve standard ISO h6 tolerances on solid round rods and stepping mandrels. On specialized high-precision orders, we reliably hold diameters to ±0.001 mm (h5 tolerance), circularity <0.0008 mm, and surface finishes down to Ra 0.05 µm through diamond micro-lapping.

Standard tungsten carbide utilizes cobalt (Co) as a metallic binder, which possesses ferromagnetic properties. In applications near electromagnetic logging sensors or magnetic recording media, cobalt induces magnetic distortion. Nickel (Ni) binders provide a completely non-magnetic matrix with superior chemical resistance against acids and salt spray, making it the premier choice for downhole drilling and chemical pump seals.

Conventional vacuum sintering frequently leaves microscopic voids and gas pockets within the sintered structure. Sinter-HIP applies 60 to 100 bar of high-pressure argon gas during the liquid-phase sintering state, collapsing internal pores and raising relative density to 99.9%. This drastically increases transverse rupture strength (TRS) and eliminates surface breakout during wire-EDM operations.

Standard sintered blanks or in-stock carbide rods with h6 ground tolerance typically ship within 3 to 5 business days. Custom tooling molds, intricate step-ground mandrels, or special powder pressing dies require 12 to 18 working days, inclusive of tooling preparation, pressure sintering, multi-stage diamond grinding, and CMM metrology inspection.

We actively export wear-resistant parts to more than 20 countries worldwide, with major distribution across the United States, Germany, Canada, Mexico, Australia, Japan, and Italy. All international shipments comply with international maritime packaging rules, include commercial export invoicing, and can be fulfilled on FCA, FOB, CIF, or DDP terms.
