SK-5A PLUS Dental CNC Milling Machine 90 Degree Cutting Electric Spindle Auto

Product Specification

Product Introduction

The SK-5A PLUS is a high-precision dental CNC milling machine built around three core capabilities: 90° cutting, an electric spindle and automatic calibration. Its B axis swings from +30° to -90°, so the machine can cut at a true 90° angle and machine single-unit and multi-unit crowns, implant crowns and bridges that conventional three-axis or limited-swing mills cannot reach. The electric spindle removes the need for an external air source, keeping torque stable and the work floor clean, while the automatic calibration routine resets tool length and blank position before every job so accuracy stays within ±0.01mm with almost no manual setup.

Three Core Selling Points

1. 90° Cutting Capability. The B axis travels from +30° to -90°, giving a genuine 90° cutting angle. This lets the SK-5A PLUS finish the intaglio surfaces, screw channels and emergence profiles of crowns and bridges in one setup, with no collision between spindle and workpiece and no need to reposition the blank by hand.

2. Electric Spindle. The electric spindle replaces the traditional pneumatic spindle, so no external air compressor or air line is required. Torque stays constant across the 0-60,000 rpm range, vibration and noise drop, and the machine runs the same on any 220V bench without extra plant equipment.

3. Automatic Calibration. Before each job the machine automatically calibrates tool length and blank position, then compensates for wear during milling. Milling accuracy is held within ±0.01mm job after job, scrap from manual zeroing disappears and a new blank can be loaded by any operator.

Applications

The SK-5A PLUS is primarily used in high-precision machining for dental restorations, and is compatible with zirconia, wax, PMMA and resin composites. It meets the dental industry demand for high precision, high efficiency and personalised customisation. Whether in batch production or single-unit custom work, the SK-5A PLUS delivers stable performance for crowns, bridges, inlays, orthodontic appliances and other precision machining fields.

Advantages

90° Cutting Geometry: The wide B-axis swing reaches -90°, allowing single-setup machining of complex crowns and multi-unit restorations.
Electric Spindle Design: No external air source is needed, which reduces dependence on plant equipment and improves stability and durability.
Automatic Calibration: Tool length and blank position are calibrated automatically, keeping ±0.01mm accuracy without manual zeroing.
Cast Aluminum Body: The unibody cast aluminium frame absorbs shock and holds accuracy under high load.
High-Definition Camera and Remote Control: A built-in camera streams the working chamber in real time and supports remote visual operation.
High-Precision Machining: Consistent milling quality across every restoration type.

Product Features

High-Efficiency Machining: Supports high-speed milling of hard materials such as zirconia, suitable for dental restoration machining and jewellery carving.
Real-Time Remote Monitoring: The built-in camera and remote visual control let users check machine status and adjust parameters from anywhere.
Breakpoint Resume Milling: After an interruption the job continues from the breakpoint instead of restarting, avoiding waste of material and time.
Wide Material Compatibility: Zirconia, wax, PMMA and resin composites.
Simple Daily Operation: Automatic calibration plus 12-bur magazine keeps changeover time short for single-operator labs.

Summary

With 90° cutting, an electric spindle and automatic calibration, the SK-5A PLUS combines reach, reliability and repeatability in one compact dental CNC milling machine. It handles complex restorations that limited-swing mills cannot reach, runs without an air compressor, and holds ±0.01mm accuracy from the first blank to the last.
