5 axis dental Milling Machine For Zirconia Crown

 

The 5 axis dental Milling Machine For Zirconia Crown integrates modern CNC control with an intuitive operating interface, making daily use straightforward in dental laboratories and clinics.

Dry milling is used in the process, eliminating the need for water cooling. This keeps the working area cleaner and reduces routine cleaning and maintenance workload.

The machine achieves micron-level precision when milling crowns. The A-axis rotation reaches ±360°, while the B-axis ranges from +25° to -135°, allowing stable processing of complex geometries and detailed anatomical shapes.

It is compatible with a wide range of dental materials, including zirconia blocks, PMMA resin, PEEK, and wax, covering both temporary and permanent restoration workflows.

With a spindle speed up to 60,000 RPM, combined with optimized tool paths, processing time is reduced while maintaining surface quality and accuracy. This helps laboratories respond faster to production demands and daily case turnaround requirements.

1. Innovative Clamp Design – Material Utilization Increased by 30%

Traditional clamping systems usually require a relatively large safety margin around zirconia blanks because of uneven force distribution, especially at the corners. This often leads to more unused material being left after milling.

The V-shaped structure combined with an adjustable pressure plate allows the blank to be held more tightly and evenly. The force is distributed more uniformly across the material, reducing unnecessary clearance requirements.

After optimizing the tool path, the safety margin can be reduced to around 0.5 mm on all sides, compared with about 1.0 mm in conventional systems.

For every 10 blanks processed, this design can save material equivalent to around 3 additional crowns, which translates to roughly 30% material savings in batch production.

In daily laboratory use, this directly lowers raw material cost, especially in high-volume production environments.

2. Breakpoint Resume Function – Efficiency Improved by 80%

The control system records cutting progress in real time through non-volatile memory (NVRAM), including tool position, machining path, and processing parameters.

When power is interrupted or the program stops unexpectedly, the system can retrieve the last saved position after restart and continue machining from the last completed layer.

There is no need to re-align the workpiece or reset the tool.

In a typical 20-minute crown milling cycle, about 16 minutes of repeated work can be avoided, leaving only the remaining unfinished segment to continue. This reduces unnecessary reprocessing time by up to 80%.

In production environments, this improves machine utilization and makes delivery timing more predictable.

3. 850W High-Power Spindle – Faster and More Stable milling

The 850W spindle provides stronger cutting torque, allowing stable machining of high-hardness zirconia at higher speeds while reducing vibration and tool deflection.

Processing efficiency improves by more than 20%, with full crown milling time reduced from around 8 minutes to under 6 minutes.

Surface finish quality reaches Ra < 0.6 μm, which reduces or eliminates the need for extensive post-polishing.

Tool wear is also reduced by approximately 15% due to more stable cutting conditions and lower vibration.

4. Integrated Clamp and Tool Magazine System – More Compact and Efficient Design

The clamping system and automatic tool changer are integrated into a single module, reducing the need for separate structures for fixture storage and tool management.

The overall footprint is reduced from about 1.2 m² to 0.8 m², saving approximately 33% of working space.

Maintenance becomes simpler, as inspection and servicing can be carried out from a single access panel without multiple disassembly steps.

Overall maintenance time and service cost are reduced by around 25%, lowering the total cost of ownership while improving daily operational efficiency.
