A Machining Center or Milling Machine specification sheet typically includes key technical parameters that define its capabilities. Below is a general breakdown of common specifications:
—
1. Machine Type
– Vertical Machining Center (VMC) – Spindle orientation is vertical.
– Horizontal Machining Center (HMC) – Spindle orientation is horizontal (better for heavy-duty machining).
– 5-Axis Machining Center – Allows simultaneous multi-axis movement (X, Y, Z + A/B rotary axes).
—
2. Table & Work Envelope
– Table Size (Length × Width) – e.g., 800 × 500 mm
– Maximum Load Capacity – e.g., 500 kg
– X/Y/Z Travel Distance – Axis movement range (e.g., X: 1000 mm, Y: 600 mm, Z: 500 mm)
—
3. Spindle Specifications
– Spindle Speed Range – e.g., 8,000–15,000 RPM (High-speed spindles may go up to 50,000 RPM)
– Spindle Power – e.g., 15 kW / 20 HP
– Spindle Taper Type – BT30, BT40, CAT40, HSK63A (common toolholder standards)
—
4. Feed Rates & Rapid Traverse
– Max Feed Rate – e.g., 10 m/min (~400 IPM)
– Rapid Traverse Rate – e.g., 24 m/min (~945 IPM)
—
5. Accuracy & Repeatability
– Positioning Accuracy – Typically ±0.005 mm (±0.0002″) or better with high-end machines.
– Repeatability Accuracy – Often ±0.002 mm (±0.0001″).
—
6. Tool Changer System
– Tool Capacity: Number of tools in the magazine (e.g., 24-tool carousel).
– Tool Change Time: e.g., ≤3 sec (for high-speed ATCs).
—
7. Control System & Software Compatibility
– CNC Controller Brand: Fanuc, Siemens, Haas, Heidenhain, etc.
– Programming Compatibility: G-code standard support (+CAM software integration).
