1. High-Rigidity Mechanical Structure for Micron-Level Precision (±0.003mm Repeatability)

Precision milling is fundamentally determined by machine rigidity and vibration control.
T20W-E adopts high-alloy steel precision-ground linear guides combined with high-precision ball screw transmission, replacing lightweight aluminum-frame structures commonly used in entry-level machines.

High elastic modulus of steel structure ensures excellent anti-torsion stability during long-term high-speed milling
Motor resolution < 1μm enables ultra-precise motion control
Repeat positioning accuracy up to ±0.003mm

Smooth and continuous margin lines when milling zirconia or glass ceramic
Significantly reduced edge chipping
Less manual polishing and post-processing time
2. Extended B-Axis Swivel Range for Complex Undercut Restoration

Most conventional 5-axis dental milling machines are limited to a B-axis range of approximately ±20° to ±30°, which may cause machining blind spots in complex geometries.

T20W-E features an extended:

A-axis: ±360° (full rotation)
B-axis: +25° to -135°

Eliminates undercut machining limitations
Enables precise milling of complex implant abutments and multi-unit bridges
Allows tool access from optimal angles for anterior aesthetic restorations

Improved restoration fit accuracy
Lower remake and adjustment rate
Stronger adaptability for complex clinical cases
3. 1400W German High-Performance Spindle (80,000 RPM)

Equipped with a 1400W German-made electric spindle, T20W-E delivers both high torque stability and ultra-high-speed cutting performance.

Power: 1400W
Speed range: 10000 – 80,000 RPM

Stable cutting force for hard materials such as zirconia, glass ceramic, and titanium premill abutments
High-speed finishing ensures smoother surface quality
Water cooling system reduces cutting heat and prevents micro-cracks in ceramic materials
Extends tool life for both roughing and finishing burs
4. 12-Position Automatic Tool Changer (ATC) for Continuous Production

Compared with machines equipped with only 4–6 tool positions, T20W-E significantly improves workflow automation.

12-tool automatic tool magazine supports multi-material and multi-step processing
Automatic switching between roughing, finishing, and detailing tools
Fully NC-code controlled tool selection

Enables uninterrupted multi-case production
Reduces operator intervention
Supports true "unmanned overnight milling" capability
5. High-Speed Operation with Low Noise Design (Clinic-Friendly)

Despite its industrial-grade performance, T20W-E maintains excellent acoustic control.

Measured performance:

Idle noise: < 45 dB
Operating noise: < 70 dB (tested via UT353 sound meter)

Stable dynamic balance of internal transmission system
Suitable for chairside or in-clinic CAD/CAM environments
Does not interfere with doctor–patient communication

FAQ:

Q1: How is the waterproof and anti-corrosion structure designed in wet milling? Will long-term use cause rust or electrical failure?

A:T20W-E adopts a strict chamber separation design, fully isolating the machining area from the mechanical transmission system and electrical components.

The machining chamber is equipped with a stainless-steel inner lining, while all critical motion parts-such as the high-alloy steel linear guides and precision ball screws-are protected by custom-designed fully sealed dustproof and waterproof covers.

In addition, the entire machine body is treated with an anti-corrosion coating, effectively preventing coolant, zirconia dust, and ceramic debris from penetrating internal structures.

This design fundamentally eliminates the risk of:

Rust on linear guides or ball screws
Short circuits caused by coolant leakage
Long-term humidity-related mechanical failure
Q2: As a cost-effective 5-axis wet milling machine, can it handle continuous high-load production? Is durability sacrificed?

A:"Cost-effective" refers to optimized supply chain and component selection, not a compromise in durability.

T20W-E is built for industrial-level continuous operation:

Equipped with a 1400W German high-performance spindle, ensuring long-term stability and precision
Heavy-duty structural base (~72kg total machine weight) enhances vibration absorption during high-speed milling
High-rigidity mechanical architecture significantly reduces fatigue during long-hour operation

Even under 10+ hours of daily continuous production, the machine maintains stable performance with minimal mechanical degradation.

Q3: If a tool breaks during machining, can the machine detect it automatically?

A:Yes. T20W-E is equipped with a tool monitoring and breakage detection system.

During every automatic tool change (ATC) cycle, the system performs:

Tool length verification
Tool integrity inspection

If a tool breakage occurs during cutting (e.g., zirconia or titanium milling), the system will:

Immediately trigger an alarm
Automatically pause machining
Prevent further damage to spindle and material

This ensures maximum protection for both the machine and high-value restorations.

Q4: Is the machine compatible with mainstream CAD/CAM software and NC code systems?

A:Yes. T20W-E adopts an open NC-code control architecture, ensuring full compatibility with mainstream dental CAD/CAM workflows.

It supports widely used CAM software such as:

Hyperdent
Millbox

It is also fully compatible with major design systems including:

Exocad
3Shape

Workflow is fully open:
Scan → Design (STL) → CAM nesting → NC code → Milling

Data transfer is supported via:

USB 2.0
100M Ethernet port

No closed ecosystem or software lock is required.

Q5: Is daily maintenance complicated due to its compact structure and wet milling system?

A:No. T20W-E is designed for easy maintenance and fast servicing.

Key design advantages include:

Large front-access door for easy chamber cleaning
No dead corners inside the machining area
Modular coolant filtration system for quick removal and cleaning
Tool-free or simple-tool maintenance design

Operators can complete routine maintenance such as:

Waste residue cleaning
Coolant tank replacement
Filter cleaning

within minutes.

We also provide:

Step-by-step video tutorials
Standardized maintenance guides

Therefore, even junior technicians can operate and maintain the machine efficiently.
