Twin-Spindle CNC Turn-Mill Machine

Model / Category:

HMS-750MYS

Product Overview:

A turn-mill machine combines turning and milling in one CNC machine, completing multiple operations in a single setup and reducing transfers between machines.

HMS-750MYS Twin-Spindle Turn-Mill Machine

The HMS-750MYS combines main and subspindles with a Y-axis live turret for front- and back-side machining of complex parts. It offers Φ580 mm swing over bed and a BMT55-12T live turret.

Key features
1. Twin motor spindles each run up to 4,000 rpm; the subspindle receives the part for back-side machining.
2. BMT55-12T live turret with ±50 mm Y-axis travel and 2.3 kW live-tool motor supports turning, milling, drilling and tapping.
3. Capacity: Φ580 mm swing over bed, Φ410 mm machining diameter, Φ370 mm over the toolholder and 635 mm length. Main/subspindle bar capacities are Φ52/Φ46 mm.
4. Distance between the two spindles is 45–690 mm, supporting work transfer.
5. 45 mm ball-type guideways, main-spindle motor 15 kW/98 N·m, subspindle motor torque 57 N·m and net weight 5,000 kg.

Frequently asked questions

Specifications and capacity
Q: What distinguishes this configuration?
A: Twin spindles and a Y-axis live turret allow the subspindle to receive the part for back-side machining, while the Y axis supports eccentric and keyway features.
Q: What are its maximum dimensions?
A: Φ580 mm swing over bed, Φ410 mm machining diameter, Φ370 mm over the toolholder and 635 mm maximum length.
Q: What are the spindle outputs?
A: Both reach 4,000 rpm. The main motor is 15 kW/98 N·m and subspindle motor torque is 57 N·m; spindle noses are A2-6/A2-5.

Machine selection
Q: Twin or single spindle?
A: A twin-spindle model supports front- and back-side operations; a single-spindle machine with tailstock may suit long shafts.
Q: HMS-750MYS or HMS-750MY?
A: The MYS has a subspindle for back-side work. The MY uses a single spindle with tailstock for long shafts.

Production and service
Q: Can a chip conveyor or bar feeder be added?
A: Yes. Both are available as automation options.
Q: How is accuracy supported?
A: 45 mm ball-type guideways, SYNTEC servo drives and spindle transfer positioning help reduce re-clamping errors.
Q: What service and training are included?
A: The machine is offered with warranty, on-site installation and commissioning, and operation and maintenance training. Specific warranty terms are subject to the contract.
