CNC Universal Milling from three axes up to five axes The MBC-620 is the correct choice for a versatile CNC Machining Center capable of machining 3 axes to 5 axes simultaneously at a competitive price! Using the latest cross slideway design between X- and Y-axis, the machine provides efficiency, rigidity, stability, and accuracy making it a must have when considering a 5-axis machine. Ergonomic design, fluent chip evacuation, and 32T Arm Type automatictool changer is designed for easy access and maintanence for the operators. Promach’s MBC-620 offers an affordable entry into the world of 5-axis simultaneous machining while maintaining strict accuracy and precision requirements in a machine.
Machine’s solid contruction offers maximum stability, accuracy and precision resulting the best surface quality at an affordable price.
Isolated Direct Drive Spindle Systemis designed to isolate heat source and to minimize thermal displacement, providing accuracy and longer spindlelifespan.
Without the use of transmissionbelt or gear, spindle is driven by direct-coupled motor offering lower noise, less back gap, and less vibration during operation. Spindle tool pulling force is 1200kgf or 11760N.
Rotary Table single swivel B- and C-axis is equipped with encoder to ensure precision machining during 5-axis synchronized processing. Maximum table load is 300kg.
Hydraulic braking system is used on bothB- and C-axis offering high reliability. Tailstock supporting the rotary table ensures precision under heavy load.
B-axis tilting table at +110 degree and -50 degree.
Access door on the side provides easy loading/unloading of tools. Arm-type 32T tool changer offering fast tool to tool change at 5 seconds.
