Ultrasonic Mould Polisher

I. GENERAL DESCRIPTION
Our new model is a bi-function polishing machine, with ultrasonic vibration polishing function and EDM EROSION function.
During ultrasonic polishing, the vibration movement repeats at maximum 28,000 times per second. During EDM erosion, the machine discharges high frequency electric spark to remove excessive material at adjustable speed.

It works much faster than manual polishing; it can polish deep and narrow areas where manual polishing cannot reach. Its EDM erosion function offers an economical and fast approach to polish extra-hard alloy or carbide.

Previous models, customer dissatisfaction concerns: the hand piece is big and clumsy & high level of abrading sound. To satisfy the customer need, we produce a new model which is light and handy ; It also operates at a lower sound level.

By using sectional assembly, the machine size decreases noticeably and the machine quality improves significantly. also modified the hand piece overheating problem

1. Ultrasonic vibration tracking system
2. Nine step numerical EDM power control
3. Nine step numerical vibrating power control.
4. Able to adjust the EDM gap automatically to obtain maximum output.
5. Fine EDM process, suitable for intricate mould.
6. Controlled power output and stored current consume little power.
7. The hand piece is light and handy, reduce fatigue and promote efficiency.
8. Machine occupies a small work place.


II. SPECIFICATIONS
1. Application: ribs, slits, tapered holes of dies, different shaped holes and other areas that are hard to polish or finish by hand
2. Applicable Material: steel, carbide, glass, precious stones
3. EDM Fluid: kerosene or water
4. Input: 220V~10% 50/60Hz
5. Output: 60W, 19-28 KHz, 9-stage output selection

III. EFFECT OF POLISHING
1. Appearance: after polishing, the surface should be flatly lapped; all EDM, wire-cut or milling marks should be removed.
2. Roughness: After EDM Erosion Stage 1, the surface roughness should be below Ra0.3. After complete ultrasonic finishing, the surface roughness should be around Ra0.012 (mirror finish).
