Turned Parts We Make
Most of our turning work is high-mix, tight-tolerance hardware that goes straight into an assembly. Typical part families by industry:
- Semiconductor equipment - CF and KF vacuum flanges, rotary vacuum spindles, gas and fluid nozzles, and PEEK insulating bushings for wafer-handling and process-chamber hardware
- Medical devices - 316L and titanium surgical instrument handles, cannulated pins, threaded connectors and autoclavable PPSU components, passivated to ASTM A967
- Optics & photonics - High-concentricity aluminium lens barrels, retaining rings with fine internal threads, and spacer sleeves for multi-element assemblies
- Automotive & EV - Driveshafts, sensor bodies, high-strength fasteners and machined busbar terminals in 17-4 PH, alloy steel, brass and copper
- Oil & gas - Inconel 718 and Duplex 2205 valve stems, downhole mandrels, wear bushings and pressure-retaining adapters for severe-service tools

Standard tolerances apply to metals; engineering plastics are quoted per material. Sharp corners are broken with a chamfer or radius unless the drawing specifies otherwise.
Turning Equipment & Process Controls
- Multi-axis CNC lathes with live tooling - C-axis and Y-axis control with driven tools for cross-drilling, keyway milling, flats and tapping in the same clamping as the turned features.
- Mill-turn centres - Turned and milled features completed in one setup for shafts, spindles and housings that would otherwise move between two machines.
- Automated bar feeders and robot-tended cells - Unattended production runs for bar stock parts, with part catchers and in-cycle tool-wear compensation.
- In-process gauging - Bore gauges, ring and plug gauges and dial indication at the machine; Zeiss CMM and surface roughness testing at final inspection.
- Difficult materials - Rigid tooling and controlled feeds for Inconel 718, 17-4 PH, Duplex stainless and titanium, and sharp polished tooling for PEEK, PTFE and POM.
Materials for CNC Turning
Certified bar and billet stock with mill test certificates and full lot traceability:
Turned Metals & Superalloys
Stainless steels (303, 304, 316L, 17-4 PH), titanium, Inconel 718, Duplex 2205, brass, copper, aluminium, mild steel and alloy steels (4140, 4340).
Turned Engineering Plastics
PEEK, POM (Delrin), PTFE, Nylon, PPSU (Radel), polycarbonate and Ultem PEI for bushings, insulators, seals and fluid-handling parts.
Finishing & Secondary Operations
Turned parts rarely ship as-machined. We manage the finishing chain and machine to the pre-plating dimension so the part meets the drawing after coating:
- Passivation and electropolishing of stainless steel to ASTM A967 for medical and high-purity fluid parts
- Electroless nickel, copper and zinc plating with masked journals and threads
- Anodizing of aluminium barrels and housings, including optical black
- Cylindrical grinding and micro-finishing of bearing journals and seal diameters
See the surface finishing service for process specifications and coating thickness allowances.
Quality Documentation Delivered With Every Lot
Every production lot ships with complete inspection and traceability documentation to satisfy quality audits and supplier qualification files:
First Article Inspection (FAI)
Setup approval measured on Zeiss CMM before a production run is released.
Dimensional inspection report
100% or AQL sampling report against the drawing, per customer inspection plan.
Mill Test Certificate (MTC)
Raw material chemistry and mechanical properties, traceable to the lot.
Certificate of Conformance (CoC)
Issued with every shipment under the ISO 9001:2015 quality system.
Metrology equipment, calibration schedules, and complete inspection workflows are detailed under quality & compliance.

Frequently Asked Questions
What is the difference between CNC turning and mill-turn machining?
CNC turning rotates the workpiece against a stationary tool to produce round features: diameters, faces, grooves and threads. Mill-turn machines add driven tools with C- and Y-axis control, so cross-holes, keyways, flats and off-centre features are cut in the same setup without moving the part to a milling machine. For shafts and housings with both round and prismatic features, mill-turn removes a setup and the datum error that comes with it.
What runout and concentricity can Shine hold on turned parts?
Concentricity and runout are held within 0.010 mm on features turned in a single setup, such as bearing journals, optical lens barrels and precision spindles. Where a part must be reversed, we machine from a datum diameter and verify with dial indication and CMM before release.
Which thread standards can you produce?
ISO metric coarse and fine, UN/UNC/UNF, NPT and BSPP tapered and parallel pipe threads, and custom thread forms from the drawing. Threads are cut or tapped to the specified class and verified with go/no-go gauges. For small bores, Ø1.5–5 mm threads are produced to 3× diameter depth and Ø5 mm and above to 4–6× diameter.
Do you turn engineering plastics as well as metals?
Yes. PEEK, POM (Delrin), PTFE, Nylon, PPSU, polycarbonate and Ultem PEI are turned with sharp polished tooling and controlled feeds to avoid heat build-up and burr formation. Material certificates are supplied for traceable plastic stock the same way as for metals.
How do small-quantity and production turning runs differ?
Prototypes and first articles are set up on multi-axis lathes with CMM inspection. Recurring production moves to bar-fed or dedicated production lathes with First Article Inspection at setup and in-process dimensional checks, released against your delivery schedule.
