Requirements of high-speed CNC machining for spindle bearings
High-speed CNC machining spindle bearings should have the characteristics of high precision, good rigidity, stable operation and small thermal expansion. There are several types of spindle bearings for high-speed CNC machining: transmission belt type, transmission gear type, direct-drive type and high-speed electric spindle. High-speed CNC machining can apply direct-coupled spindle bearings and high-speed electric spindles. Most of the other spindle bearings cannot meet the basic speed ratio requirements of the high-speed CNC machining management center.
Regulations of drilling and cutting tools for high-speed CNC machining management center
In the CNC lathe, it can be said that improving the drilling and cutting tool of the CNC lathe is equivalent to improving the high efficiency of production and processing. This is especially true for high-speed CNC machining centers. CNC machining high-speed CNC machining drilling passes are generally 20-40m/min, and natural drilling is not without speed. The perfect application of the servo motor allows high-speed CNC machining to have a qualitative leap, and there is often a multi-directional improvement in the high efficiency of production and processing and the precision of production and processing.
Regulations for high-speed CNC machining of CNC machine tools
High-speed CNC machining CNC machine tools are higher than the general CNC machining center CNC machine tools. High-speed CNC machining of CNC machine tools must have rapid data processing methods and higher engineering features.
The oil cavity is opened between the two guide rail working surfaces of the hydrostatic guide rail used in CNC machining. After entering the grease with a certain working pressure CNC precision machining force, the static pressure floating oil can be generated, so that the guide rail working surface is in pure liquid Contradiction, no damage, good precision maintenance; at the same time, the contradiction index is also very low, so that the output power of the drive is greatly reduced; the low-speed gear has no creep, the load-bearing capacity can be large, and the bending rigidity is good; in addition, the oil has The actual effect of vibration absorption and good vibration resistance.
The sliding guide rails used in CNC machining have the advantages of simple structure, convenient manufacturing, good bending rigidity, and advanced vibration resistance. There are two common types of guide rail plastics: PTFE guide rail soft belt and epoxy resin wear-resistant guide rail coating. The characteristics of plastic-laminated sliding guides are good contradictory characteristics, good wear resistance, stable fitness exercises, good shock absorption, and good process performance.
