CNC Machining

Single-point cutting of rotating bar stock and blanks on CNC lathes — OD/ID turning, facing, boring, grooving and thread cutting for concentric cylindrical features on shafts, pins, bushings and fittings.

Tolerance

Typically IT7–IT9; tighter on request per feature

Materials

Carbon & alloy steel, stainless steel, aluminum, brass, cast iron

Applications

Linkage pins, hydraulic glands, spacers, threaded components

Multi-axis rotary-cutter machining on vertical machining centers — face, end and pocket milling, contouring, drilling and boring of prismatic parts, with positional accuracy held between datum features.

Tolerance

Typically ±0.02–0.05 mm on machined features

Materials

Steel, stainless, aluminum, castings

Applications

Manifolds, housings, mounting plates, fixture bases

Hole-making with twist and carbide drills followed by tapping or single-point threading — internal and external threads to ISO metric 6H/6g, UNC/UNF 2B/2A and NPT/BSPT/BSPP forms, verified by thread gauge.

Applications

Fastening features, ports, fittings

Chipless cold-forming of external threads between hardened dies — plastic deformation work-hardens the flanks and preserves unbroken grain flow, giving higher fatigue strength and finer finish than cut threads.

Applications

High-tensile fasteners, studs, threaded rods

Abrasive-wheel finishing of hardened and precision surfaces — cylindrical grinding between centers, surface grinding on magnetic chucks, and through-feed centerless grinding for high-volume shafts and pins.

Tolerance

To ±0.005 mm typical on ground diameters

Applications

Shafts, pins, seats, wear surfaces

Low-speed abrasive-stone finishing of bores under controlled pressure — corrects size, roundness and cylindricity while imparting the crosshatch texture required for oil retention in hydraulic bores.

Applications

Hydraulic cylinder tubes and bores
