Products advantages
1. 1400W German Spindle & 4mm Shank Tools: Stress Optimization in Titanium Machining
Titanium is known for its low thermal conductivity, high chemical reactivity, and strong work-hardening tendency, making it one of the most demanding materials in dental CNC machining. It requires exceptional spindle rigidity and torque stability during cutting.
The T20W-E is equipped with a 1400W German electric spindle, operating within a speed range of 10,000 to 80,000 RPM. During titanium premill abutment processing, the spindle delivers stable high-torque output, combined with 4mm shank carbide tools designed for heavy-duty cutting loads and high feed rates.
The high-power spindle effectively eliminates issues such as tool stalling or slippage during deep cutting operations. It ensures stable machining of implant platforms, transmucosal regions, and screw channel structures, achieving low surface roughness (Ra value reduction) while minimizing heat-induced work hardening and extending tool life.
2. Micron-Level Resolution & ±0.003mm Repeat Positioning Accuracy for Implant Interface Precision
The connection interface of implant abutments (e.g., hex or conical structures) demands extremely tight tolerances to ensure long-term stability and prevent micro-movement or bacterial infiltration.
The T20W-E is built with:
High-alloy steel precision linear guideways
Ground ball screw transmission system
Motor resolution below 1 μm
Repeat positioning accuracy of ±0.003 mm
This ultra-precise motion control ensures consistent machining of implant connection geometries. The resulting interface achieves micro-level fit accuracy, reducing micro-gaps at the implant–abutment junction and improving long-term biomechanical stability and clinical sealing performance.
3. Continuous Production Logic: 12-Tool ATC System & Low-Noise Operation
Designed for both chairside environments and laboratory workflows, the machine emphasizes automation, efficiency, and operator comfort.
The system integrates a 12-position Automatic Tool Changer (ATC), enabling continuous multi-step machining without manual intervention. Optimized mechanical balancing ensures stable acoustic performance:
Idle noise: <45 dB
Operating noise: <70 dB (tested via UT353 sound level meter)
Operators can load multiple tool types-including titanium roughing tools, finishing burs, ceramic milling burs, and wax cutters-simultaneously. The system automatically switches tools based on NC programming, enabling uninterrupted production cycles. Its low-noise design makes it suitable for chairside installation without disrupting patient communication or clinical workflow.

FAQ:
Q1: How easy is it to switch fixtures when processing different materials such as titanium premill abutments and glass ceramics? Will fixture replacement affect machining accuracy?
A:The T20W-E is equipped with a quick-change modular fixture system designed specifically for multi-material workflows. To accommodate both glass ceramic blocks (standard blank holders) and titanium premill abutments (dedicated implant interfaces), the fixture system adopts a modular structural design.
Fixture replacement only requires loosening the positioning bolts and swapping the entire module. Thanks to the high-rigidity high-alloy steel guideways and stable reference base structure, no complex realignment or re-zeroing process is required after replacement. Material switching can be completed within approximately 2 minutes, without compromising machining accuracy or repeatability.
Q2: In wet milling, mixing titanium chips and glass ceramic debris often leads to sludge formation and pipe blockage. How does the T20W-E prevent this issue?
A:This is a common problem in conventional wet milling systems. The T20W-E addresses it through a multi-stage separation and high-pressure flushing system.
High-flow coolant nozzles continuously flush the machining area, rapidly removing titanium chips and ceramic particles during cutting. In the filtration system:
Heavy titanium debris is first separated in the primary sedimentation chamber
Fine glass ceramic particles are captured by a secondary high-density filter element
This staged filtration design prevents cross-material agglomeration and sludge formation, effectively protecting the pump system and extending overall fluid circuit lifespan.
Q3: Long-term titanium machining inevitably causes mechanical wear and potential precision drift in a 5-axis system. How is long-term accuracy maintained and recalibrated?
A:The machine is equipped with an automatic calibration system (Calibration Kit) and intelligent one-click compensation software.
After extended operation or when users observe minor deviations in abutment margins, operators can simply load a standard calibration block into the fixture and run the calibration program. The built-in probing system automatically detects axis deviations and mechanical zero offsets, then applies compensation values directly into the control system.
This eliminates the need for on-site engineers or external metrology equipment, allowing end users or distributors to restore precision independently and efficiently.
Q4: Is the 4 × 56 mm tool shank a universal industry standard? Are users required to purchase tools exclusively from you?
A:The T20W-E adopts an open tooling standard system. The 4 mm shank diameter and 56 mm tool length are widely recognized international standards in dental CAD/CAM machining.
There is no forced tooling lock-in. Users and distributors are free to source compatible carbide burs, titanium cutters, or ceramic milling tools from global suppliers (Germany, Japan, or local manufacturers), as long as they meet the dimensional specifications. The ATC system and NC control program fully support third-party tooling compatibility.
Q5: The machine operates at up to 1800W peak power. Is this suitable for standard dental clinic power supply? Will it interfere with other digital equipment such as X-ray or CBCT systems?
A:The 1800W rating represents the maximum peak load condition, including full spindle operation, simultaneous axis movement, and coolant system activity. The average operating power is significantly lower during normal machining cycles.
The system integrates an industrial-grade power filtering and wide-range voltage stabilization module, effectively suppressing inrush current and voltage fluctuations during startup and spindle acceleration.
Under standard 220V clinical or laboratory power supply conditions, the T20W-E operates safely without causing electrical interference or voltage instability to sensitive equipment such as CBCT scanners or dental X-ray systems.
