We are a professional CNC precision machining manufacturer providing full OEM & custom service for cosmetic instrument metal accessories, this complete beauty device handpiece kit is our core customized product line.
The whole kit consists of four core machined components: brushed aluminum main handpiece housing, aluminum inner lining sleeves, 304 stainless steel drive spindle shaft and H62 brass threaded tail end cap.
All parts are processed from solid metal bar stock via Swiss automatic lathe and 3-axis CNC milling, covering complex machining features including internal & external threads, side window cutouts, tapered contours, side slots, head guide grooves and spline gear milling on spindle.
After precision deburring, ultrasonic cleaning and professional metal surface finishing, all parts go through full dimensional inspection before set assembly, ready for direct assembly into micro-needling, skin care, facial beauty and cosmetic treatment pens for beauty equipment brands worldwide.
We support custom dimension, material replacement and surface finish adjustment according to customer drawings or physical samples.
