Description
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.
The reason why customers choose HI-TAK !
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.
