The Skymach UM1460 Universal Knee-Type Milling Machine is an industrial heavy-duty multi-purpose milling center designed for toolrooms, mold shops, and production facilities requiring extreme flexibility. Built on a rigid 3,600 kg Meehanite cast iron frame, the UM1460 features dual 7:24 ISO 50 spindles (horizontal and vertical), a bi-rotary universal milling head that swivels 360° horizontally and 360° vertically, and a generous 1700 x 400 mm worktable that swivels ±45° for machining helical flutes, spirals, and angular slots with a dividing head.
Comprehensive Universal Machining Capabilities
- Dual-Spindle Architecture: Features both a heavy-duty horizontal milling spindle (60 - 1850 RPM, 12 steps) and a versatile vertical spindle (50 - 1520 RPM, 12 steps), both equipped with standard 7:24 ISO 50 tapers, driven by a powerful 7.5 kW main motor.
- Bi-Rotary Universal Milling Head: With two independent 360° rotational axes, the universal head can be positioned at any spatial angle in seconds, enabling face milling, chamfering, side milling, and end milling without re-clamping the workpiece.
- ±45° Swiveling Knee Worktable: The massive 1700 x 400 mm table rotates ±45° clockwise and counterclockwise, allowing operators to execute helical milling, gear hobbing setups, and complex angled geometries directly.
- Expansive 3-Axis Travel Envelope: Long 1300 mm longitudinal travel (X), 420 mm cross travel (Y), and 600 mm vertical knee travel (Z) accommodate large mold blocks, fabrication frames, and multi-station vises.
Advanced Feed System & Construction
- Servo Motorized Feed Drive: Equipped with a 2.36 kW / 15 Nm high-torque feed motor providing infinitely adjustable feeds (X/Y: 25 - 800 mm/min, Z: 8 - 267 mm/min) and rapid traverse across all three axes.
- Induction-Hardened Guideways: Wide rectangular box ways on the column and saddle are induction hardened, precision ground, and coated with low-friction Turcite-B to ensure stick-slip-free motion and long-term geometric accuracy.
- Complete Cooling & Lubrication: Integrated 90 W / 25 L/min coolant flood pump and centralized lubrication system keep cutting tools cool and slideways continuously protected.
