Description:
YJCS-5B is a bi-function polishing machine. It works much faster than manual polishing; it also
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.
Parameter:
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: single phase 220V 50Hz
5. Output: 60W, 19-28 KHz, 9-stage output selection
6. Dimensions: 230 x130 x78mm
7. Weight: Approx. 5Kg
Features :
1.Machine occupies a small work place.
2. Ultrasonic vibration tracking system
3. Nine step numerical EDM power control
4. Nine step numerical vibrating power control.
5. Able to adjust the EDM gap automatically to obtain maximum output.
6. Fine EDM process, suitable for intricate mould.
7. Controlled power output and stored current consume little power.
8. The hand piece is light and handy, reduce fatigue and promote efficiency.
EFFECT OF YJ-5B 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).
3. Ultrasonic Finishing Speed:
Tip Type | Roughness | Approx. Speed |
Ceramic stone tip | Ra2.5-Ra0.5 | 1cm2/min |
Brass rod tip | Ra0.1-Ra0.2 | 2cm2/min |
Hard wood tip | Ra0.3-Ra0.05 | 1cm2/min |
Soft wood tip | Ra0.05-Ra0.012 | 1cm2/min |
The speed may differ due to operator familiarity and working area complexity.
4. EDM Erosion Speed: 2mm3/min.
