KA-22
Ren Thang Machine
The KA-22 is a flagship automatic dual-spindle PCB lead cutter featuring integrated motorized copper brush cleaning for extra-wide boards up to 420 mm wide. Its rough-cut and finish-cut dual blades balance mechanical load, while the rotating brush actively sweeps away trimmed lead debris and solder dross.

【Key Machine Features & Advantages】
- Flagship automatic dual-spindle PCB lead cutter with integrated copper brush, built for extra-wide boards and high-density PCBA lines.
- Wide processing range: handles PCB widths from 10 to 420 mm (unlimited length), ideal for large server boards and power supplies.
- Dual-blade design (rough cut + finish cut with 3/4 HP, 4,500 RPM spindle) balances cutting load and significantly extends blade life.
- Integrated motorized copper brush (600 RPM / 1/5 HP) actively sweeps away solder dross and trimmed lead residuals from the board underside.
- Stepless conveyor feed rate from 0 to 3 m/min with height-adjustable entry/exit tracks for seamless docking to any wave soldering brand.
- Integrated hold-down plates and support pins prevent board sagging or thermal warping during high-speed cutting.
- Heavy industrial chassis (350 kg; 2700 × 1200 × 1100 mm) dampens mechanical resonance for quiet, ultra-stable 24/7 continuous operation.
- Recommended with NK-200 / NK-250 micro-grain tungsten carbide circular blades (optional accessory).
【Revision Notes】 銜接軌道前後高低可調，適用不同廠牌焊錫爐；鎢鋼刀NK-200/NK-250為選購品。
