Haas TM-1P

With a 10-pocket carousel, a 6,000 rpm spindle and 400 ipm (10.2 m/min) rapids, the Haas TM-1P is the mid-size toolroom mill for jobs that should not need an operator at the spindle for every tool. Travels are 30 × 16 × 16 in (762 × 406 × 406 mm), identical to the TM-1, on the same 47.8 × 10.5 in (1,213 × 267 mm) table.

How much the changer helps depends on the part. Haas quotes 5.7 s tool-to-tool and 6.5 s chip-to-chip, which is unhurried, so the gain is in unattended running more than in raw cycle time. A carousel pocket takes a tool up to 3.5 in (89 mm) across and 12 lb (5.4 kg). Tool length has no listed maximum. With 4 in (102 mm) to 20 in (508 mm) between spindle nose and table, a long drill above a vise is the case to measure before ordering tooling.

The spindle carries a 7.5 hp (5.6 kW) rating with 33 ft-lbf (45 N·m) of torque at 1,200 rpm. Speed is what changes: 6,000 rpm here, 4,000 rpm on the TM-1. In practice that moves small end mills and spot drills in aluminium and plastics closer to their proper surface speed. It does nothing for a large face mill in steel, which is torque-limited either way. Belt drive, grease-packed bearings and air cooling complete the spindle specification, and the taper is CT or BT 40.

Next size up is the TM-2P, with 40 in (1,016 mm) of X on the same Y and Z, the same 10 tools and the same 350 lb (159 kg) table load. The TM-1P weighs 4,440 lb (2,014 kg) as shipped. It runs from 220 VAC single-phase at 40 A, or from three-phase at 220 VAC and 25 A or at 440 VAC and 13 A, and has a published starting price of US$51,995.
