verticalmillingtapping

Product Overview
The VMC855 is a CNC vertical machining center designed for high-precision machining of medium-sized components and molds. It supports milling, drilling, tapping and boring operations with a large travel range and stable, rigid construction for consistent results in production environments.

Key Features

• Large travel range: X 800 mm, Y 550 mm, Z 550 mm — suitable for medium-sized components and molds.
• High-speed machining: Maximum feed rate 10,000 mm/min and rapid traverse up to 32 m/min for efficient cycle times.
• Versatile operations: Milling, drilling, tapping, boring and multi-operation capability.
• Precision performance: Repeat positioning accuracy ±0.004 mm for tight tolerances in roughing and finishing.
• Stable machine design: Rigid structure to handle large or heavy workpieces while maintaining accuracy.

Recommended Configurations

• Spindle system: High-precision spindles (SKF, NSK), center coolant spindle options.
• Feed system: Servo motor or stepper motor configurations; linear guideways and ball screws.
• Cooling system: Centrifugal or vibration pumps; water-soluble or oil-based coolant systems.
• CNC control: Compatible with FANUC, Siemens, GSK, KND, SYNTEC, Mitsubishi, etc.
• Tooling system: Disc, chain-type or linear tool changers.
• Measuring & monitoring: Heidenhain linear scales; Renishaw OMP60/TS27R probes; tool-breakage detection.
• Other options: Chip conveyor, oil mist collector, oil cooler, cooling water tank, multi-joint robot arm.

Application Case

• Client: Automotive parts manufacturer (Japan).
• Workpieces: Precision engine components and transmission parts.
• Results: Achieved tight tolerances (±0.005 mm), improved surface finish, reduced cycle time, high repeatability and increased throughput.
