Product Information

The T22100 heavy-duty deep-hole boring machine is a member of our company’s heavy-duty series of deep-hole machining centers, developed in response to the processing characteristics of today’s large and heavy workpieces with internal holes and to market demand. This machine is specifically designed for machining cylindrical deep-hole workpieces; it features high rigidity and excellent dimensional stability. The spindle offers three-step stepless speed regulation—high, neutral, and low—providing a wide speed range, while the feed system is driven by high-power AC servo motors, enabling it to meet the requirements of various deep-hole machining processes. The workpiece clamping mechanism employs a mechanical device for secure and reliable end-face support. The machine is capable of performing deep-hole boring on large-diameter, heavy-duty components. During boring, cutting fluid is delivered through the boring bar to the cutting zone at the headstock end, simultaneously flushing away chips; during reaming, chip evacuation is performed externally, requiring the use of dedicated reaming tools, tool holders, and specialized fixtures.
The machine tool primarily consists of a bed, headstock, lubrication unit, feed system, workpiece center support, workpiece rest, boring bar support, feed carriage, cooling system, hydraulic system, and electrical system.
