Performance Features
▪ Combined design of linear guideways and sliding guideways provides the machine with excellent vibration resistance;
▪ The rectangular ram is mounted in a fully enclosed cast-iron spindle headstock, offering mechanical symmetry and thermal symmetry;
▪ High spindle speed, high power, and high torque;
▪ The spindle headstock adopts imported ultra-precision angular contact ball bearings with oil-air lubrication, and the spindle sleeve is cooled by circulating cooling oil, ensuring spindle stability during high-speed operation;
▪ Comprehensive precision compensation system: coaxiality self-detection and compensation, ram deflection tie-rod compensation, spindle headstock center-of-gravity offset compensation, and boring bar axial compensation;
▪ Various optional accessory heads, rotary tables, and other attachments make the machine configuration more flexible;
▪ Integrated with JIER S-series dedicated software for CNC double-sided floor-type milling and boring machines, featuring fault pre-warning and wire rope life monitoring functions to enhance intrinsic safety of the equipment.
Application Fields
▪ The machine tool can be widely used for rough and finish machining of various shafts, rollers, and complex welded structural parts in industries such as construction machinery and automotive. It offers functions including milling, boring, drilling, reaming, tapping, and hole boring, and is especially suitable for machining symmetrical structural parts, significantly improving machining efficiency and accuracy.
