Horizontal Milling Machine: Heavy-Duty Material Removal for High-Volume Production

What is a Horizontal Milling Machine?

A Horizontal Milling Machine uses a horizontally oriented spindle to mount cutting tools, removing material via peripheral milling. Its robust design excels in slotting, facing, and heavy stock removal for large workpieces.

Categories & Capabilities

1. Universal Horizontal Mills
   • Swiveling table for angular cuts (±45°).
2. Bed Mills
   • Fixed table with moving spindle (rigidity for die/mold work).
3. Pallet-Changing HMCs
   • Automated pallet systems for 24/7 production.
4. Twin-Spindle Mills
   • Double output for symmetric parts (e.g., axle housings).

Key Advantages

• Chip Evacuation: Gravity clears chips efficiently.
• Rigidity: Cast iron construction handles 1,500 N·m cutting torque.
• Tool Capacity: 40+ tool magazines for complex jobs.
• High MRR: Removes 500 cm³/min in steel.

Applications

• Automotive: Engine blocks, transmission cases.
• Railways: Bogie frames, coupling systems.
• Mold Making: Large injection molds.

Operation Steps

1. Workholding: Bolt workpiece to angle plate or fixture.
2. Tool Setup: Install face mills, shell mills, or indexable cutters.
3. Milling Operations:
   • Roughing: 5 mm depth of cut at 800 mm/min.
   • Finishing: 0.5 mm depth at 2,000 mm/min.
4. Coolant Management: High-pressure flood cooling (70 bar).
