Services
CNC Milling
Our CNC milling capabilities utilise advanced machining centres with 3-5 axis functionality for complex geometries. With spindle speeds up to 15,000 RPM and tool changers up to 30 stations, we produce precision components from metals like aluminium and stainless steel, as well as specialist polymers. This technology enables efficient prototyping and high-volume production for aerospace and motorsport applications.
CNC Turning
Combining CNC and manual turning capabilities, we produce turned components up to 720mm diameter with tight tolerances. Our Doosan and Goodway lathes with Y-axis milling functionality support complex turned-milled parts, while manual lathes handle specialist prototyping requirements. This versatility ensures optimal solutions for both high-volume production and unique engineering challenges.
EDM Machining
Our Agie Charmilles EDM systems enable precision machining of complex shapes in conductive materials. The wire eroding machine handles workpieces up to 1200x700x400mm, while the spark eroder accommodates components up to 800x500x265mm. This technology complements our milling and turning capabilities for complete in-house manufacturing of intricate components that would be difficult to machine conventionally.
5 Axis Milling
The Deckel Maho DMU50 and Matsuura MX-330 5-axis machining centres allow simultaneous multi-directional machining of complex 3D surfaces. With automatic pallet changers and high-speed spindles up to 15,000 RPM, we achieve tight tolerances on intricate components for scientific and motorsport applications, reducing setup times and improving dimensional accuracy through single-setup machining.
Quality Assurance
Our ISO9001:2015-certified quality system includes two Mitutoyo CMM machines and comprehensive inspection equipment. We provide full traceability with certificate of conformance reports and accommodate customer-specific inspection criteria. Regular equipment calibration and trained inspection staff ensure compliance with exacting standards across scientific, marine, and motorsport sectors.
