CK7520CM/CK40M/CK50M Sealing Ring Special CNC lathe 
Introduction This series of machine tools is specially designed for the cutting of special materials,such as rubber and engineering plastics.The main body of machine tool adoptsthe structure of high strength cast iron, the key parts are analyzed by finiteelement analysis, the whole machine is rigid and high, and the high speedmachining stability is good.The machine adopts servo spindle, the two axis islinear guide rail, improves its machining accuracy and high speed feedperformance, shorten the auxiliary time.The machine tool design pays attentionto the environmental protection function, the inclined bed body structure andthe cooling system can take away the heat generated by the cutting processquickly;Cuttings and cuttings can be used to quickly and automatically recoverthe chip.This machine is especially suitable for high speed and high precisionmachining of rubber and engineering plastics.
The design of the machine tool is novel, the panel iseasy to operate, the whole sealing is protected, the three leakage effect isespecially obvious.Combined with its high power, high precision and highperformance. Performancecharacteristics of machine tool 1. Adopting imported or domestic high-quality precisionspindle bearing, high rigidity, high precision spindle bearing arrangement,grease lubrication, v-belt transmissionand stable spindle operation. 2. Full-body high-strength cast iron bed has goodvibration and thermal stability, reducing vibration and improving the rigidity,durability and machining precision of the machine tool. 3. Adopting imported or domestic high-end numericalcontrol system, electric cabinet adopts temperature control device, centralizedmachine tool operation panel. 4. Fast feeding speed and high precision. 5. Using special mechanism knife disk to meet variouscutting requirements.
6. Using cuttings and cuttings to make the chiprecycling automatic and convenient.
