Contract Manufacturing for Mechanical and Plant Engineering
Milled, turned and boring mill parts to drawing, from spare part to series
Mechanical and plant engineering needs a wide variety of components: shafts and flanges, housings and bearing blocks, plates, brackets and machine beds, often as single parts, as spare parts or in small series. MWA – Mechanische Werkstätten Anhalt GmbH in Halberstadt has been manufacturing these parts to drawing since 1985.
Milling, 5-axis milling, boring mill machining, turning and grinding come from a single source. This keeps a part with several operations in one company, and you have one contact person from the raw part to the final inspection.

Which components do we manufacture for mechanical engineering?
- Shafts, axles, pins and bushings
- Flanges, rings, discs and covers
- Housings, gearbox housings and bearing blocks
- Base plates, brackets, holders and strips
- Machine beds, columns and frames, also as welded assemblies or castings for machining
- Fixtures and production equipment
- Spare parts to drawing or sample
The parts are made to your drawing or 3D model. Components up to Ø 2,500 mm, 6,000 mm length, 3,000 mm height and 25 t are possible.
Which processes are used?
Round parts such as shafts and flanges are turned, prismatic parts such as plates and housings are milled. We mill multi-sided parts with inclined surfaces on 5 axes, machine large housings and machine beds on the boring mill, and grind bearing seats and mating surfaces on request.
More on the pages CNC milling, Turning and grinding, Boring mill machining and in the guide Processes compared.
Which materials are common in mechanical engineering?
The most common are structural steel, quenched and tempered steel and case-hardening steel, plus cast iron for housings and beds, stainless steel for parts in contact with media, and aluminium, bronze and brass. On request, we procure the material with a material certificate according to EN 10204.
More on the page Materials in CNC contract manufacturing.
Do you also manufacture spare parts from a sample?
Yes, if no drawing is available any more, a sample can serve as the basis. The old part is measured, material and tolerances are agreed with you, and the manufacturing documentation is created from this. For older machines and plants, this is often the fastest way to a spare part.
It is important that you tell us where the part is installed and which dimensions are critical to function, for example bearing seats, fits and hole patterns.
Single part, small series or series?
In mechanical engineering, small quantities are the rule: a prototype, a spare part, a pilot series or recurring batches. We manufacture from single parts to series and, for recurring batches, quote graduated prices on request.
More on the page From prototype to series.
How is quality verified?
Every part is inspected against the drawing. On request, you receive a measurement report, a first article inspection report and a material certificate according to EN 10204. Our quality management is based on ISO 9001.
More on certificates in the guide Material certificate according to EN 10204 and on tolerances in the guide General tolerances according to ISO 2768.
How do you get a quotation?
Send us your drawing or 3D model, material, quantity and requested delivery date via the Contact page. We check feasibility free of charge and prepare a non-binding quotation. On request, we sign a non-disclosure agreement in advance.
