How Does CNC Turning Work at XC Machining?
CNC turning is a subtractive manufacturing process where a workpiece rotates in a lathe chuck at speeds from 500 to 4,000 RPM while a stationary single-point cutting tool removes material to produce the finished geometry. The cutting tool follows G-code programmed paths generated from your CAD file to achieve dimensional accuracy within ±0.025 mm.
XC Machining performs facing, OD turning, threading (internal and external), knurling, drilling, boring, reaming, grooving, and taper turning on a single CNC setup. Automatic tool changers (ATCs) switch between 8–12 tools in under 3 seconds to minimize cycle time and maintain ±0.025 mm accuracy.
What Are Common Applications for CNC Turned Parts?
CNC turning produces threaded fittings, bushings, couplings, and custom connectors with UNC, UNF, metric, and NPT threading to Class 2A/3A fit. Applications include hydraulic systems, automotive fuel lines, aerospace fluid connectors, and robotic joint assemblies.
XC Machining CNC turns precision shafts, spindles, and axles from 2 mm to 200 mm diameter with concentricity within 0.005 mm TIR and surface finish to Ra 0.4 μm for bearing-fit applications.

What Surface Finishes Are Available for CNC Turned Parts?
Sanding removes tool marks and burrs from CNC turned parts, producing a uniform finish at Ra 1.6–3.2 μm suitable for painted or coated surfaces.
Polishing achieves Ra 0.05–0.4 μm mirror finish on CNC turned stainless steel, brass, and aluminum parts for medical instruments, optical fittings, and decorative hardware.
Brushing creates a directional satin texture at Ra 0.8–1.6 μm on aluminum and stainless steel turned parts, reducing glare for industrial equipment.
Anodizing (Type II standard, Type III hard-coat) forms a 5–80 μm oxide layer on aluminum turned parts with Rockwell hardness up to 70 and custom color options.
Electropolishing smooths out surface irregularities on turned metal parts, improving both the appearance and corrosion resistance, often used for stainless steel components.
Vibratory finishing tumbles CNC turned parts with ceramic or plastic media to deburr edges uniformly, achieving Ra 0.8–1.6 μm across full-batch production quantities.

CNC Turning Frequently Asked Questions
What parts can CNC turning produce?
CNC turning produces cylindrical and rotationally symmetric parts including shafts, rods, pins, bushings, pulleys, spacers, and threaded fasteners. The process creates external/internal threads, precision bores, grooves, tapers, and knurled surfaces on parts from 2 mm to 200 mm diameter in metals and plastics.
Can CNC turning be used for plastic parts?
Yes. XC Machining CNC turns ABS, polycarbonate, PTFE (Teflon), Nylon 6/6, Acetal (Delrin), PEEK, polypropylene, and UHMWPE. Plastic turning requires reduced cutting speeds and sharp, positive-rake tooling to prevent heat deformation. We optimize feeds and speeds per material to maintain ±0.05 mm tolerance on plastic turned parts.
Milling vs Turning
In CNC milling, the cutting tool rotates while the workpiece is clamped stationary — suited for prismatic parts with pockets, slots, and contours. In CNC turning, the workpiece rotates while the tool is stationary — suited for cylindrical parts like shafts, pins, and bushings. XC Machining offers both services.
What is a CNC turning center?
A CNC turning center is a computer-controlled lathe with automatic tool changers (8–12 station turrets), live tooling for milling and drilling, and optional sub-spindles for back-end operations. XC Machining turning centers produce shafts, pins, bushings, threaded parts, and multi-feature components in a single setup with ±0.025 mm accuracy.
