Model / Category:

HMS-320MY

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-320MY Compact Turn-Mill Machine

The HMS-320MY is a compact Y-axis turn-mill machine for precision machining of small shafts and discs. It offers Φ500 mm swing over bed and 300 mm machining length, with a BMT45-12T Y-axis live turret and tailstock.

Key features
1. Combined machining: the BMT45-12T live turret has a 2.3 kW live-tool motor for turning, milling, drilling and tapping in one setup.
2. Y-axis travel of ±35 mm enables eccentric holes, keyways and other non-rotational features.
3. Capacity: Φ500 mm swing over bed, 350 mm machining diameter, Φ220 mm over the toolholder, 300 mm length and Φ46 mm bar capacity.
4. Spindle: A2-5 nose, Φ56 mm bore, up to 4,500 rpm and 7.5 kW/35.8 N·m output.
5. Structure: 35 mm ball-type guideways, X/Z travel 250/400 mm, dimensions 2,230 × 1,800 × 1,750 mm and net weight 3,500 kg.
