Core machining services

Three specialist capabilities

Available individually or combined, from a single prototype to serial production runs of thousands.

Precision Micro-Milling

3-axis CNC milling with micro tooling down to 0.1mm diameter. Carbide, ceramics, hardened steels, titanium, PEEK, and more. Surface finishes to Ra 0.4µm.

How it works

From CAD file to finished part

01

Send your design

Upload a STEP, IGES, or DWG file with your tolerance requirements and material preference. No drawing? We can work from a sketch or existing part.

02

Receive a quote

We review your design for manufacturability and respond within 24 hours with accurate pricing and a lead time estimate for your quantity.

03

Production begins

Every part is fully traceable — from raw material certificate through in-process inspection to final dimensional report. ISO 9001 compliant processes throughout.

04

Worldwide delivery

Shipped from Rovaniemi, Finland to clients across Europe, the UK, US, and Asia — packaged specifically for precision components.

MVJ-1 Modular
MQL System

We don't just machine parts — we build the equipment that makes better machining possible. The MVJ-1 is our minimum quantity lubrication system, engineered in-house for high-precision shops that need control, cleanliness, and flexibility.

Modular 1-litre reservoir expandable without downtime or re-plumbing
Independent nozzle control per valve block — tune flow per tool
24 VDC CNC integration with M-code on/off and optional analog flow control
Compatible with neat oils, esters, synthetics, water-soluble fluids, and ethanol

Quality management

Every part, fully traceable

We follow ISO 9001 quality management principles across every order — working towards formal certification. Raw material certificates, in-process measurement records, and final inspection reports are retained for every job — if a question ever arises, the entire process history is reviewable. From raw stock to finished part, traceability is built in, not added on.
