Production Machining
Production machining makes medium to high volumes of the same part, from hundreds to many thousands, with consistent quality and cost per piece. It uses optimised CNC programs, dedicated fixtures, bar feeders and in-process checks to keep every batch matching the approved sample.
What it is
Once a part is approved, the process is fixed: the program, tooling, fixtures and inspection plan. Bar feeders, multi-part fixtures and tool-life management keep machines running efficiently with consistent output.
Quality is maintained with first-piece approval, in-process sampling and final inspection. For repeat orders, the same process is reused, so later batches match the first.
Typical applications
- Automotive and two-wheeler components
- Fasteners, fittings and connectors
- Pump, valve and motor parts
- Electrical and switchgear components
- Components for OEM assembly lines
Suitable materials
- Free-cutting steels and alloy steels
- Stainless steel
- Brass
- Aluminium
- Engineering plastics
Points to consider
- Share annual volume as well as batch size; it affects fixture and tooling investment and price.
- Small design changes (standard radii, relaxed non-critical tolerances) can cut cycle time significantly at volume.
- Agree packaging, labelling and delivery schedule up front for line-side supply.
- Consider whether forging, casting or cold forming plus finish machining is cheaper at very high volumes.
Frequently asked questions
What quantities count as production machining?
Generally from a few hundred pieces upward. Pricing improves with volume as setup, programming and fixture costs are spread.
Can you supply on a schedule?
Yes. Blanket orders with scheduled deliveries are common, so you hold less stock and receive parts as needed.
How do you keep batches consistent?
The approved process is frozen and each batch goes through first-piece approval, in-process checks and final inspection against the drawing.
