CKT61125/160/200B CNC HORIZONTAL LATHE WITH BORING BAR
This machine is a multifunctional lathe developed by our company on the basis of a large flat-bed CNC horizontal lathe with boring function. The bed is optimized, the overall weight is increased, the carriage is lengthened, widened, and thickened, and a dedicated boring tool holder is supplied. It can cut the inner holes of parts, and the processing efficiency, accuracy, and rigidity are better than ordinary CNC lathes. Adopting a semi enclosed protective structure and equipped with Siemens systems. The main transmission of turning is automatic four speed continuously variable speed, with two linked control axes. The X and Z axes use ball screw pairs, AC servo motors, and precision reducers to achieve servo movement, semi closed loop control, and have good positioning accuracy and repeated positioning accuracy.
Product application areas:
1. Medium and large hydraulic cylinders
2. Full process machining of wind turbine spindles
3. The Drum in the Paper Industry
4. Wire rope drum of crane
5. Cathode rod drum
6. Centrifuge drum
7. Efficient turning of precious metals such as high-temperature alloys, titanium alloys, steel ingots, rollers, and laser cladding materials
8. Processing of thin-walled parts such as outer circle turning, inner hole boring, end face drilling, tapping, shaft surface drilling, milling, etc
