The Skymach 4H (X6325) Precision Turret Milling Machine is constructed on a high-rigidity Meehanite cast iron frame, engineered for ultra-versatile manual and semi-automatic milling, drilling, boring, and slotting operations. Featuring a 1270 x 254 mm hardened worktable, an R8 (optional ISO 40) spindle, a swiveling turret head (±90° tilt / ±45° nod), 3-speed automatic quill feed, and a 2.2 kW (optional 3.7 kW) motor, the 4H (X6325) is the benchmark machine for mold & die making, prototyping, toolrooms, and repair workshops.
Comprehensive Machining Capabilities
- Universal Multi-Angle Machining: Swiveling head articulates ±90° left-to-right and ±45° forward-and-backward to mill angled chamfers, compound bevels, and oblique hole patterns without reclamping.
- Precision Drilling & Boring: 127 mm quill stroke with 3 automatic downfeed rates (0.045, 0.086, 0.142 mm/rev) and micro-stop depth gauge provides sub-millimeter boring depth repeatability.
- High-Capacity Envelope: 780 x 400 x 400 mm travel range with up to 510 mm spindle-to-table clearance accommodates tall jigs, rotary tables, and dividing heads.
Key Engineering Highlights
- High-Frequency Hardened Slideways: Induction-hardened and ground table and dovetail ways lined with Turcite-B low-friction coating ensure effortless feed motion and minimal stick-slip.
- 360° Horizontal Ram Swivel: Sliding overarm ram extends, retracts, and rotates 360° on top of the column for oversized plate machining.
- Dual Speed Options: Choose between the rugged 16-step belt-pulley drive (up to 4,500/5,440 RPM) or the electronic variable inverter head (65 - 4,000 RPM) for stepless dial-in speed selection.
