What is Precision Machining?
Precision machining is the process of shaping material into smaller, more intricate parts by removing material with a cutting tool to very tight tolerances. The three principal machining processes are turning, drilling, and milling, supported by grinding, lapping, honing, and spark erosion (EDM) for the finest tolerances and hardest materials.
In every machining operation, the cutting tool must move in precisely controlled directions. The primary motion is the cutting speed; the movement of the workpiece is the secondary motion, or feed. Together with tool sharpness and machine rigidity, these determine the accuracy and surface finish achievable. GTMA precision machining companies offer:
- CNC milling and turning of complex, high-tolerance components
- Wire and die-sink EDM for hardened materials and fine detail
- Thread grinding, cylindrical grinding, and optical profile grinding
- Gundrilling, deep-hole boring, and honing
- Lapping and superfinishing for critical surface requirements
Applications of Precision Machining Services
Subcontract precision machining supports the most demanding UK industries. The oil and gas sector relies on precision-machined valve components, downhole tooling, and sealing surfaces that must perform reliably under extreme pressure and temperature. Precision machined components are equally critical in aerospace, medical devices, motorsport, scientific instruments, and toolmaking, where verification through in-house or subcontract metrology confirms every part meets specification.

GTMA is the Gauge and Tool Makers Association – a UK trade association connecting engineering buyers with accredited precision machining companies and precision engineering specialists across the supply chain.
Precision Machining FAQs
A precision machining company removes material from a workpiece using processes such as turning, milling, drilling, grinding, and EDM to produce components to very tight tolerances. Most operate as subcontract suppliers, machining parts to customer drawings or CAD models with certified inspection.
Standard CNC machining typically holds tolerances of ±0.01mm to ±0.05mm. Precision processes such as grinding, lapping, and jig grinding can achieve tolerances measured in microns, with surface finishes to match. The achievable tolerance depends on the material, geometry, and process combination.
Precision machining describes the outcome: achieving very tight tolerances and high accuracy. CNC machining describes the method: computer numerical control of machine tools. Most precision machining today is performed on CNC machines, but manual processes such as lapping and hand finishing still play a role in the tightest-tolerance work.
Aerospace, oil and gas, medical devices, motorsport, defence, scientific instrumentation, and toolmaking all depend on precision machined components. Any application where parts must fit, seal, or perform reliably under load requires precision machining.
