T21xxG/TK21XxG Series New Deep-Hole Drilling and Boring Machines

This series of deep-hole drilling and boring machines is a specialized machine tool for machining cylindrical deep-hole components. It is suitable for drilling, boring, and roll‑forming operations on cylindrical workpieces with deep holes. During drilling, it employs an internal chip‑removal system (BTA method), in which the oil supply unit delivers lubricant into the cutting zone, while chips are conveyed through the drill rod to a chip‑collection hopper located at the rear of the machine bed.

Product Information

This series of deep-hole drilling and boring machines is a specialized machine tool for machining cylindrical deep‑hole components. It is suitable for drilling, boring, and roll‑forming operations on cylindrical workpieces with deep holes. During drilling, an internal chip‑removal system (BTA method) is employed: lubricant is supplied through the tool holder into the cutting zone, and chips are conveyed via the drill rod to a chip‑collection hopper at the rear of the machine. For boring and roll‑forming, lubricant is delivered through the tool holder into the cutting zone, with chips being expelled forward toward the chip‑discharge chute. When performing combined boring and roll‑forming operations, either standard boring‑roll‑forming tools or high‑efficiency, automatically expanding–contracting scraping‑and‑polishing tools can be used, enabling high‑speed, high‑efficiency machining of cylinder bores.
The bed guideways of this series of deep-hole drilling and boring machines are double‑rectangular, quenched for superior wear resistance. A protective cover is mounted on the outer side of the bed guideways, providing excellent external protection and preventing oil leakage. Feed and lubrication movements are driven by servo motors, with gear‑rack or ball‑screw transmission, ensuring high rigidity and convenient control. The feed system employs AC servo motors to guarantee the safety of the machine tool, cutting tools, and workpieces. The main motor is a variable‑frequency drive unit with stepless speed regulation, offering enhanced adaptability.
