The Skymach XK7136 (XH7136) is a heavy-duty, high-precision industrial vertical CNC milling machine engineered for versatile batch machining, mold making, and precision part manufacturing. Designed with a wide heavy HT300 cast-iron base, precision pre-tensioned ball screws, and a powerful 5.5 kW servo spindle motor, the XK7136 delivers exceptional cutting rigidity, dynamic accuracy, and high surface finish quality.
Comprehensive Machining Capabilities
The XK7136 CNC Milling Machine is engineered to handle diverse multi-axis machining operations in a single clamping setup:
- Planes & Facings: High-efficiency face milling and end milling of horizontal, vertical, and inclined planes.
- Grooves & Slots: Precision cutting of keyways, standard T-slots, dovetail guide grooves, and deep clearance pockets.
- Gear & Spline Components: Multi-axis synchronized interpolation for machining spur gears, helical gears, spline shafts, and industrial sprockets.
- Spiral & Thread Profiles: Internal and external thread milling, spiral oil grooves, and continuous helical contouring.
- Complex 3D Surfaces: High-speed 3-axis continuous contouring for die-casting molds, stamping dies, and curved aerospace/automotive parts.
- Boring, Drilling & Tapping: Inner hole boring, reaming, deep-hole drilling, and synchronized rigid tapping.
Key Technical Highlights
1. High-Rigidity Cast Iron Bed Structure
Constructed from premium HT300 grade cast iron, stress-relieved through thermal annealing to eliminate internal stresses. The ultra-wide column and base design effectively absorbs cutting vibrations during heavy milling operations.
2. BT40 High-Speed 8,000 RPM Spindle
Equipped with a precision BT40 spindle driven by a 5.5 kW high-torque AC servo motor. The spindle assembly is dynamically balanced and supported by precision P4 angular contact bearings, ensuring thermal stability and vibration-free cutting at high speeds up to 8,000 RPM.
3. High Dynamic Precision & Rapid Feeds
Precision double-nut ground ball screws paired with high-rigidity linear roller guideways deliver rapid traverse rates of up to 20/20/20 m/min on X, Y, and Z axes. The machine achieves exceptional positioning accuracy of ±0.008 mm and repeatability of ±0.005 mm.
4. Generous Work Envelope & 400 kg Table Capacity
Featuring an expansive 1250 x 360 mm ground worktable with three 18mm T-slots, supporting workpieces up to 400 kg. With an extended X-axis travel of 860 mm, Y-axis travel of 450 mm, and Z-axis travel of 550 mm, it readily accommodates oversized components and multi-station fixtures.
5. Ergonomic Enclosure & Automatic Chip Management
Fully enclosed protective guarding with safety glass windows and interlocked sliding doors ensures operator safety and keeps coolant and chips contained. Optional automatic screw or link-type chip conveyors with collection carts ensure continuous, maintenance-free chip removal.
