The high-performance guideway system equipped on the M15 three-axis vertical machining center is the core guarantee for its precise processing capabilities. The X and Y axes adopt Japanese THK or similar linear roller guideways, featuring low friction coefficient, high rigidity and excellent repeatability positioning accuracy, which are particularly suitable for high-speed reciprocating motion; the Z axis innovatively adopts a hard rail structure and is combined with the wear-resistant plastic-coated guideway of the spindle box. This combination not only ensures stability during heavy cutting but also effectively suppresses vibration, thereby extending the equipment's service life. This machine can not only precisely complete basic processing such as drilling, reaming and tapping, but also achieve complex processes such as contour milling, tapping, and boring. Its processing range covers various materials such as aluminum, stainless steel, and titanium alloy. It performs exceptionally well in the batch production of key components such as automotive engine blocks, motorcycle crankcase boxes, and aerospace hydraulic valve bodies, especially being suitable for the manufacturing of small and medium-sized precision parts with strict form tolerance requirements.
