Micro and Small Turned Parts: the Types We Mass Produce
Seven families of precision turned parts, from Ø 0.5 mm to Ø 65 mm. For each type you will find a featured sample, the materials and the typical operations: send your drawing and we reply within 24 hours.

RF connectors and adapters
Coaxial connectors and adapters are among the most requested turned parts: brass bodies with threads, internal seats, knurling and gold or nickel plating.
They are produced in volume on automatic and CNC lathes, with cross holes and milled features made in the same cycle.
- Brass
- Gold / nickel plating
- Knurling
- Threads
Variants: connectors for PCB mounting
Pins, screws and special small parts
Threaded pins, dowels, bushings and special screws with shaped heads, cross holes and grooves. Small repetitive parts, ideal for automatic bar-fed production.
Tight diameter tolerances and dimensional checks on every batch.
- Steel
- Stainless steel
- Brass
- Threading
- Cross holes
Multi-operation turned components
Parts with several operations in one cycle: turning, drilling, milling of flats and seats, threading. Flanges, bushings, bodies and fittings in aluminium and stainless steel.
Fewer handling steps keep cost and lead time under control, even on high volumes.
- Aluminium
- Stainless steel
- Milled features
- Multiple holes
Variants: turned and milled parts in aluminium and stainless steel
Micro parts for optical fiber and automotive
Small pins and terminals turned for optical fiber, automotive applications and instruments. Slender, elongated shapes with miniature seats, knurling and threads.
Optical sorting and dimensional measurement ensure repeatability on large quantities.
- Steel
- Stainless steel
- Brass
- Slender shapes
Micro brass components
Tips, nozzles, plugs, bullet-shaped pieces and small turned brass bodies, with reduced dimensions and a bright finish. Suitable for pneumatic tools, instruments and electronic components.
Brass machines very productively and allows fast cycle times.
- Brass
- Miniature parts
- Bright finish
Shafts, axles and flanges
Precision shafts and axles with flanges, shoulders, holes and threads, up to 1,000 mm long. For office machines, pneumatic tools and precision mechanics.
Centerless grinding is available for tight-tolerance diameters and high surface finish.
- Length up to 1,000 mm
- Centerless grinding
- Holes and shoulders
Variants: turned shafts, axles and flanges with holes and shoulders
Rings, ring nuts and sleeves
Threaded rings, ring nuts with shaped edges, grooved sleeves and perforated discs, typical of optical and instrument applications. Aluminium, also black anodised, and stainless steel.
Milled slots and seats are made in the machine to keep concentricity and repeatability.
- Aluminium
- Black anodising
- Threads
- Slots and seats
Variants: rings, ring nuts and sleeves
Capacity and quality control
The turning department runs 180 single-spindle automatic lathes, supported by CNC sliding-head (Swiss-type) and fixed-head lathes. Centerless grinding and edge knurling are done in-house.
| Parameter | Value |
|---|---|
| Outside diameter | 0.5 – 65 mm |
| Length | 0.5 – 1,000 mm |
| Diameter tolerance | ±0.005 mm |
| Length tolerance | ±0.01 mm |
