Machining processes we supply
CNC turning
for rotationally symmetric parts: shafts, pins, bushings, flanges and fittings.
CNC milling
for prismatic parts: housings, plates, brackets and manifolds, on 3-axis to 5-axis machining centres.
CNC grinding
for fine finishing of hardened or precise surfaces: bearing seats, pins, spools and guides.
EDM
wire and sinker, for hardened materials, sharp internal corners and contours that cutting tools cannot reach.
Laser cutting
for flat parts and blanks from sheet and plate.
Waterjet cutting
for cold cutting of thick plates, heat-sensitive materials, plastics and composites.

Dimensional and surface inspection
Machined parts are inspected against the drawing before shipment. First articles are measured in full, often on a coordinate measuring machine (CMM), and documented in a first article inspection report. Series parts are checked according to an agreed inspection plan. Surface roughness, roundness and hardness are measured where the drawing specifies them.
There is no fixed size or tolerance limit we state in advance. Send us your drawing and we will define the right production route and confirm feasibility. More on inspection and documents on the quality page.
Machining combined with casting and forging
Many parts start as a casting or a forging and are then machined. We plan both steps and coordinate them, including heat treatment and coating under secondary operations. You receive the finished part, not a raw part and a separate machining job.
Industries we supply machined parts to
Machined parts go to machinery and equipment, agricultural machinery, construction and mining equipment, commercial vehicles and hydraulics, pumps and automation. For aerospace and medical parts we work with machine shops holding the certification these sectors require.
Drawings are sent to machine shops only after your company name and logo have been removed. Request a quote for machined parts.
Frequently asked questions
Do you machine castings and forgings as well as parts from bar?
Yes. Castings and forgings we supply can be machined before delivery, and parts from bar, plate or tube are machined in the same way. In both cases you receive a finished part with one set of documents.
Do you supply prototypes and small batches?
Yes. CNC machining needs no part-specific tooling in most cases, so it suits prototypes, spare parts and small batches as well as series.
