The machining speed of the scraping and hobbing machine is more than ten times that of the honing machine, and the noise is low and pollution-free, which can save the machining cost and improve the machining efficiency. These advantages of scraping and rolling machine tool are inseparable from the characteristics of its own composition. Today, Xiaobian will take you to understand the main components of scraping and rolling machine tool.
1. Machine bed. The bed of the scraping and rolling machine tool is the basic component of the machine tool. Its rigidity directly affects the machining performance and accuracy of the whole machine tool. The body of the scraping and rolling machine tool is made of high-quality cast iron, which has good appearance and strength. The layout of the rib plate is reasonable. The two-level reinforcing rib makes the machine tool have excellent rigidity, seismic resistance and section distortion resistance. The lathe bed adopts the split splicing structure, and the guide rail adopts the medium frequency quenching grinding technology, so that the machine tool has good wear resistance and accuracy retention. The guide rail of the bed adopts double flat structure.
2. Drill pipe box. The drill pipe box of the scraping and rolling machine tool is an integral structure. The main shaft is driven by the AC main shaft motor through the narrow V-belt and the transmission mechanism. The speed range is 3-1000r / min. The main motor is the AC main shaft motor. Hydraulic stepless speed regulation. The selection of rotation speed can be determined by workpiece material, hardness, whether the tool breaks chips and other factors.
3. Feed part. Taiwan high precision ball screw feed box is used in the second half of the machine tool for tool feed. The front half of the machine tool is equipped with a t-screw feed box for workpiece position adjustment and clamping.
