Precision Turned Parts
Karry Precision manufactures precision turned parts in stainless steel, aluminum, brass, copper, carbon steel, and other machinable metals for prototypes, low-volume orders, and repeat production. Our product range includes stepped shafts, flange covers, connectors, fittings, terminal blocks, flange mounts, and other custom components produced through CNC turning and turn-mill machining.
Parts are manufactured according to customer drawings and specifications, with dimensional inspection, surface-finish control, concentricity verification, material selection, and secondary machining available according to project requirements.
Quality Control for Precision Turned Parts
-
Incoming Material Verification
Material grades and specifications are checked before machining. -
In-Process Dimensional Inspection
Critical diameters, lengths, threads, and other specified dimensions are monitored during production. -
Concentricity & Coaxiality Inspection
Rotational features and mating surfaces are inspected according to drawing requirements. -
Surface Finish Verification
Surface roughness and finishing requirements are checked according to project specifications. -
Final Inspection Before Shipment
Finished turned parts are inspected before packing and delivery. -
Engineering Support
Drawing review and manufacturability feedback are available for custom CNC turned parts.
