I. GENERAL DESCRIPTION
The YJCS-7 is a polishing machine applying ultrasonic vibration. During ultrasonic polishing, the vibration movement repeats at maximum 26,000 times per second. YJCS-7 works much faster than manual polishing; it can polish deep and narrow areas where manual polishing cannot reach.
YJCS-7 polisher is outstanding because
Automatic frequency tracking
Three grade amplitude manual selection
Reliable overload protection
Easy operation
Stable output, much less wastage than conventional ultrasonic polisher
Delicate hand piece, more comfortable to grasp
Super-portable, occupies little space
II.TECHNICAL 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. Input: single phase 110V~10% 50/60Hz
5. Output: 15W, 19-26KHz,
6. Dimensions: 120 by 74 by 37mm3
7. Weight: Approx. 0.4Kg.
III. EFFECT OF YJCS-7 POLISHING
1. Appearance: after polishing, the surface should be flatly lapped; all EDM, wire-cut or milling marks should be removed.
2. Roughness: After complete ultrasonic finishing, the surface roughness should be around Ra0.012 (mirror finish).
