Scraping – True Craftsmanship

Required for achieving tolerances which cannot be done by machining

Continuous procedures of measuring and adjustment until final completion

13

In-House Production

Critical components such as Spindles, Tables and Ballscrews are designed and manufactured in house

Large castings are also machined and assembled in house

Deriving accuracy, performance, quality and lead-time control

Issues regarding these major items are therefore quickly and easily dealt
