Newly developed! Deep hole boring machine sales World’s firstφ1.0mm L/D=400 ! Leading the industry with small-diameter deep hole drilling machine!


Our gun drilling machines meet a wide variety of needs in the medical, aerospace, automobile, and semiconductor fields. In particular, our model compatible with hole diameters of φ 1.0 to 6.0 is suitable for workpieces with extremely small diameters and L/D (depth with respect to hole diameter) exceeding 200, a task that is difficult with conventional gun drilling machines. Achieves deep hole drilling with high coaxiality (concentricity). In addition to models sold overseas, we have a large number of conventional models for domestic sales. We also can propose the most suitable machines for our customers.

Machinery development using the machining know-how of HI-TAK, experts in deep hole processing

  • Drill breakage detection function to prevent breakage of gun drills

We achieve drill breakage prevention and visualize replacement time by constantly monitoring the torque of the main axle built-in spindle motor. Prevents cutting defects caused by cutting edge wear and reduces the rate of defective products.

  • Low oscillation, high-performance hollow built-in spindle motor

-2.2kw built-in servo motor
-0.75kw built-in motor
-servo spindle motor (1.5kw, 7kw, etc.)

  • Flexible chucking technology

Can be exchanged freely between chucks, including a collet chuck or a scroll chuck, depending on its work shape

  • Highly durable chip box optimized to hole size

Maximizes the effective length of the gun drill to achieve increased machining accuracy and stability.
