CNC deep hole drilling & boring machine


CNC deep hole drilling & boring machine 

We have many differnt boring machines for different project , accept customize projects 

1, This machine is designed for cold drawn pipes or hot rolled pipes, with boring , scraping and rolling to process inner diameters to achieve good accuracy size and fine surface finishing . The cold-drawn pipes are 27 SiMn, 30CrMnSi, 42CrMn. Hot-rolled pipes could be quenched and tempered or not ,cold-drawn steel pipe is cold-drawn (hard) state or stress-relieved annealed state.

2,  Functions

2,1 Special pipe fixtures take pipes turning during boring heads rotation in rough boring processing, for rough machining straightly in holes.

2.2 Special pipe fixture take pipes turning, boring extension bar keep still, hydraulic boring rolling tools make fine processing to get fine accuracy , straight and etc.

2.3 Special pipe fixtures keep pipe keep still, Boring bar rotate, to use boring rolling tools to roll pipes to get fine finishing.
