The VMC1160 vertical machining center adopts a vertical frame structure with the column fixed to the bed. The spindle head moves vertically along the column (Z-axis), the saddle moves longitudinally along the bed (Y-axis), and the worktable moves transversely along the saddle (X-axis). Key components such as the bed, worktable, saddle, column, and spindle head are made from high-strength cast iron using resin sand molding technology. These components undergo double stress-relief aging treatment and are optimized via Pro/E and Ansys simulations to enhance structural rigidity and stability, effectively minimizing deformation and vibration caused by cutting forces.
1. Machine Tool Overall Layout
The machine adopts a vertical frame structure with the column fixed to the bed. Components are made from high-strength cast iron, undergoing double stress-relief aging treatment and optimized via simulation to enhance structural rigidity.
2. Drive System
Equipped with imported linear rolling guides for high sensitivity and positioning accuracy. Three-axis servo motors are directly connected to high-precision ball screws to eliminate backlash.
3. Spindle Assembly
Features high precision and rigidity with P4-grade bearings. The assembly undergoes dynamic balancing and run-in testing to ensure extended service life.
4. Tool Magazine
Utilizes a robotic tool changer mounted on the column, driven by a roller cam mechanism for fast, quiet, and precise tool exchange.
5. Lubrication & Cooling
Centralized auto-lubrication delivers metered oil to guide ways and ball screws. High-capacity cooling systems provide efficient circulation and dual-mode air/water cooling.
Frequently Asked Questions
Q: What is the main structural material used in these machines?
The bed, worktable, saddle, column, and spindle head are made from high-strength cast iron using resin sand molding technology, treated for stress relief.
Q: How is the Z-axis safety guaranteed?
The Z-axis servo motor is equipped with an automatic brake function that engages during power failure to lock the motor shaft.
Q: What kind of cooling system does the machine have?
It features a high-flow coolant pump and a dual-mode cooling system (switchable air/water nozzles) controllable via M-code or the operation panel.
Q: Are the linear guides durable?
Yes, the machine uses imported linear rolling guides known for low static/dynamic friction, minimal high-speed vibration, and excellent durability.
Q: Is a chip conveyor included?
A chip conveyor is available as an optional feature to handle various chip types, including fragmented and coiled chips, with overload protection.
