HTT has been the sole gun drilling machine supplier for a world famous Germany car manufacturer to drill engine valve and fuel ejecting parts since 2008.

Gun drilling engine valve is highly technical challenge to the machine builder, which require special knowledge on automatic parts feeding, holding fixturing, gun drilling tooling and in process gauging.
HTT has successfully developed a complete data base for customers either to drill stem end (small) or bell end (large).
Usually the EAU of engine valve and fuel ejection parts are pretty high, so we offer either four or six spindle gun drilling machine with drilling capacity of 1 – 4mm, 1.5 – 6 mm, 4 – 16 mm with drilling depth 300 mm, 500 mm, 800 mm.
All machines will come with counter rotation spindle to maintain CPK requirements.
Compact and high speed motorized spindle is also used to reduce space and cycle time.
