Product Description

Product Overview

Designed as a high-performance C-frame vertical machining center, the TMV-850QII distinguishes itself with a focus on heavy-duty operations. Its one-piece Meehanite casting ensures exceptional stability, even when processing large workpieces, a key edge over standard vertical mills with smaller load capacities.
Expanded Capabilities Boasting an X/Y/Z axis travel of 850×600×530 mm and a 950×600 mm worktable, it supports a maximum load of 800 kg—perfect for larger medium-sized components, from thick steel plates to bulky cast-iron parts.
Versatile Spindle Performance Equipped with a 7/24 Taper No.40 spindle, it offers flexible speeds (8,000–15,000 rpm) paired with a high-power motor (up to 18.5 kW). This combination delivers consistent cutting force for tough materials.
Efficiency Enhancements All axes maintain a 48 m/min rapid traverse rate, while the 24/30-tool magazine enables swift changes—minimizing downtime during high-volume production.
Customization Flexibility Supports tailored configurations, including spindle speed upgrades and tool magazine expansions, to match unique heavy-duty machining needs.

Key Advantages

Heavy-Load Capacity With an 800 kg max load, it outperforms smaller vertical machining centers, handling larger parts without compromising stability—ideal for automotive chassis and machinery components.
Ultra-Fast Tool Changes Sub-2-second T-T time ensures continuous operation, a must for high-throughput production lines relying on CNC machining efficiency.
Precision Under Pressure High-precision linear guideways and ball screws maintain tight tolerances even under heavy loads, rivaling the accuracy of specialized machines.
Powerful Performance The 18.5 kW spindle motor delivers superior torque for cutting thick metals, making it a top choice for industries requiring robust vertical milling capabilities.

Ideal Applications

Trusted in automotive manufacturing for machining engine blocks and transmission housings, in heavy machinery for large structural parts, and in aerospace for thick aluminum components. Its expanded capacity complements 5-axis machining centers in production lines handling diverse part sizes.
