The Polishing Machine 204 is a dedicated, compact workstation designed to interface with a 102L-style straight or contra-angle micromotor handpiece. It provides the stable power supply and control for high-speed, precision polishing and grinding in dental technology.
Technical Specifications & Material Science: The unit is a power supply/control box that outputs a regulated DC voltage to drive a separate 102L-type micromotor handpiece. It provides continuously variable speed control, typically from 1,000 to 35,000 RPM, via a knob or digital display. It includes a foot controller for hands-free speed modulation. The system supports both forward and reverse rotation, which is useful for certain polishing techniques. The handpiece itself is a pencil-grip motor known for its high torque at low speeds, making it suitable for both delicate polishing and light grinding. It accepts a wide range of 2.35mm/3mm shank tools.
Industry Standards & Compliance: Standard lab equipment with electrical safety certifications.
Application Scenarios: A core tool in dental labs for:
- Finishing and polishing acrylic dentures (especially along palatal and lingual contours).
- Contouring and polishing ceramic restorations (zirconia, e.max).
- Wax pattern carving and adjustment.
- Precision grinding of small metal components.
Usage Guidelines: Connect the handpiece to the control unit. Insert the chosen bur or polishing point. Use the foot pedal to control speed, applying light pressure. The handpiece is generally not submersible; burs are sterilizable, and the handpiece exterior is wiped clean.
Market Value Proposition: The “204” system is often seen as a standard, reliable workhorse in smaller labs. It offers more control and versatility for detailed work than a standard lathe. For suppliers, selling this system provides an entry-level high-precision equipment solution for labs, with follow-up sales for replacement handpieces, burs, and polishing points.
