The length to diameter ratios of drilled holes on some medical parts can be over 250 mm, which presents challenges to gun drilling technology.
HTT has great experience in deep hole drilling machines and tooling.
We provide the medical trade high speed spindle and precision machines to drill surgical grade materials of titanium and stainless steel.
The counter rotation is a standard feature to minimize total run-out and meet SPC quality control.
Our K single or multi-spindle machines with hydraulic steady rest have been selected by several medical parts suppliers to produce medical parts,
bone screws and surgical instruments.
Drilling hole size -6mm, max, depth 500mm.
Our processing and productivity are exceptional and we serve 85% of the industry market.
