TLS2210A deep hole drawing boring machine: ● Adopt the processing method of workpiece rotation (through the spindle hole of the headbox) and the feed motion of the fixed support of the tool and tool bar. TLS2210Bdeep hole drawing boring machine: ● The work piece is fixed, the tool holder rotates and the feed movement is made. TLS2210A deep hole drawing boring machine: ● When boring, the cutting fluid is supplied by the oil applicator, and the processing technology of forward chip removal. TLS2210Bdeep hole drawing boring machine: ● When boring, the cutting fluid is supplied by the oil applicator and the chip is discharged forward. ● The tool feed adopts AC servo system to realize stepless speed regulation. ● The headstock spindle adopts multi-stage gears for speed change, with a wide speed range. ● The oil applicator is fastened and the workpiece is clamped by mechanical locking device.
