Machine Test Reports Hub
Every straightening machine we ship is proven on real customer parts first. This page is the hub for our machine test reports: customer workpieces are sent in, the required straightness is agreed, and the parts are straightened, measured and video-recorded on the actual machine before any proposal is issued. The featured report below is the original medical drill bit test on this machine family, and the index table lists every test record we have published — medical drill bits, screwdrivers, hex wrenches and round bars, from Ø3.0 mm to Ø8.4 mm and straightness requirements from 0.03 mm to 0.3 mm.
