The processing speed of scraping and rolling machine tool is more than ten times that of honing machine tool, and it has low noise and no pollution. It can save processing cost and improve processing efficiency. These advantages of scraping and rolling machine tools are inseparable from the characteristics of their own composition, so today, Xiaobian will take you to understand the main components of scraping and rolling machine tools.
1. Machine tool bed. The bed of the scraping and rolling machine tool is the basic component of the machine tool. Its rigidity directly affects the processing performance and accuracy of the whole machine tool. The machine bed of scraping and rolling machine is cast with high quality cast iron. It has good appearance and strength, reasonable layout of ribs and plates. The secondary reinforcement ribs make the machine tool have excellent stiffness, seismic resistance and cross-section distortion resistance. The machine bed adopts split splicing structure and the guide rail adopts medium frequency quenching grinding technology, which makes the machine tool have good wear resistance and accuracy retention. The bed guide adopts double flat structure.
2. Drill pipe box. The drill pipe box of the scraping and rolling machine tool is an integral structure. The spindle is driven by an AC spindle motor through a narrow V-band transmission mechanism. The speed range is 3-1000r/min. The main motor is an AC spindle motor. Hydraulic infinite speed regulation. The selection of rotational speed can be determined by the material of workpiece, hardness, chip breakage of tool and other factors.
3. Feed part. Taiwanese high precision ball screw feeding box is used in the back half of the machine tool for tool feeding. The front half of the machine tool is equipped with a T-type lead screw feed box for adjusting the position of the workpiece and clamping.
