3-axis CNC milling machine XK715

horizontalfor steelfixed-bed

Overview
The XK715/XK716 Series CNC bed-type horizontal milling machine is engineered for large-scale machining tasks that require rigidity, precision and efficiency. With a fixed bed and movable column/head configuration, the machine provides high structural stiffness for deep and long cuts. It integrates servo-driven feed systems, high-grade alloy-steel spindle assemblies and advanced cooling to support both vertical and horizontal operations, making it suitable for heavy machinery, mold production and energy equipment manufacturing.

Main dimensions

• Table size: 2500 × 600 mm
• Table travel - X: 1800 mm
• Table travel - Y: 700 mm

Key Features

• Large travel and payload capacity: 1800 mm X-axis and 700 mm Y-axis travel for large-format workpieces.
• Precision spindle technology: High-grade alloy-steel spindle, dynamically balanced and supported by preloaded ceramic bearings with oil-mist lubrication for extended service life.
• Efficient thermal control system: High-coverage coolant flow with dual-stage filtration and oil-water separation to maintain stable cutting conditions and reduce maintenance.
• Advanced CNC feed mechanism: ±0.005 mm closed-loop positioning accuracy with intelligent servo feed adjustment for improved repeatability.
• Dual machining mode support: Configurable for vertical and horizontal machining with optional rotary attachments for expanded capabilities.
