A Production Turning Lathe produces rotational parts by turning the workpiece against a stationary tool, and modern versions add driven tools so milling and cross drilling are completed in the same cycle. The Production Turning Lathe described here is built with a sub-spindle for one-cycle completion and specified for aerospace suppliers. CNC turning with live tooling, steady rests and in-process gauging sits behind the numbers below, which are stated as delivered rather than as a best case.
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, steady rests 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.
- Shafts and spindles.
- Flanges and couplings.
- Pulleys and rollers.
- Bushings and sleeves.
- Hydraulic cylinder components.
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 added without a second operation?
Yes, if the lathe has live tooling and a C-axis. Cross holes, flats, keyways and off-centre threads are then produced in the same clamping, which improves their relationship to the turned datums.
How is roundness held on long shafts?
With a steady rest or a tailstock, correct centre height and a final finishing pass. Between centres, concentricity within 0.02 mm over a metre is a normal expectation.
What is the minimum order quantity?
One piece for prototypes and first article work. Production pricing usually starts at 50 pieces, and repeat orders run on fixtures retained from the first batch at no extra charge.
To discuss production turning lathe requirements, send the model and the drawing with the quantities required. Feedback on manufacturability is given free of charge before any order is placed.
