HTT makes a horizontal deep hole drilling machine to produce holes for power transmission shafts used in automotive and
construction vehicles.
Depending on the customer's parts requirements, we can offer a relatively wide selection of choice for our customer.
For on-center holes, we can make K-series, lathe type, deep boring machines with or without counter rotation.
For off-center holes, we can design a multi-spindle machine and secure the part-holding.
Our multi-station machine is ideal for angle holes.
HTT-USA can provide you with solutions for your specific deep hole drilling needs.
It offers high productivity, excellent precision and a long service life.
