A 6082-T6 aluminium spacer is turned complete in one cycle, so threads, grooves and cross holes keep their relationship to the turned datums. 6082-T6 aluminium spacer for robotics work is produced here with CNC turning with live tooling, sub-spindle back working and in-process gauging. The sections below describe what is held on the drawing, how the part is made and what arrives with the shipment.
The parts that matter most are the interfaces: bores, sealing faces, threads and mounting patterns. Those are held to ±0.01 mm, verified against the drawing, and recorded before anything is packed.

Manufacturing process
The operation sequence is decided before the first chip is cut: roughing to leave even stock, semi-finishing, then CNC turning with live tooling, sub-spindle back working and in-process gauging as the final operation. That order is what keeps ±0.01 mm stable as the batch runs and the machine warms up.
Material is purchased against a certificate and checked on receipt, so the composition is known before any cutting starts. Work in progress is identified by part number and operation, and the finished parts are deburred, cleaned and protected before they leave the machine area.
Typical applications
Most of the work supplied in this category falls into the following examples.
- Motor and gearbox shafts.
- Pump and valve bushings.
- Sensor mounting collars.
- Hydraulic adaptors and fittings.
- Roller and idler spindles.
Quality control and documentation
Every batch is measured against the drawing with calibrated equipment, and results are recorded against the part number rather than kept on a scrap of paper.
Material certificates to EN 10204 3.1, dimensional reports and first article inspection reports are issued with the shipment where the application requires them. Calibration dates and measurement uncertainty are recorded alongside every result.
Ordering, lead time and packaging
Quotations are returned within one working day of a complete drawing package. Lead time is quoted from drawing approval, not from the date of enquiry.
Frequently asked questions
Can milled features be included?
Yes. Live tooling and a C-axis produce flats, cross holes and keyways in the same cycle, which keeps their relationship to the turned datums rather than adding a second setup tolerance.
What tolerance is normal for turned diameters?
±0.01 mm is routine and ±0.005 mm is achievable on small diameters with a finishing pass and in-process gauging. Concentricity is usually held within 0.02 mm.
What file formats do you need for a quotation?
STEP or IGES for the 3D model and a PDF drawing with tolerances, material and surface finish called out. Native files from SolidWorks, Creo or Inventor are also accepted.
To discuss spacer requirements, send the model and the drawing with the quantities required. Feedback on manufacturability is given free of charge before any order is placed.
