Main features intruduce:
Lathe bed: The bed is cast with resin sand technology and has good quality. The guide rail is quenched and ground with high hardness and high precision.
Main spindle system: The main drive system adopts stepless frequency conversion design to realize stepless speed change in gears, which fully meets the user needs for each speed range. The spindle has the advantages of high rigidity, high torque and wide speed range. The head of the machine tool adopts a two-support spindle structure, and the front and rear supports areThe main support, the rear end is the auxiliary support. Spindleassembly adopts a high-rigidity structure composed of two-way thrust ball bearings and NN series double-row short cylindrical roller bearings. The rear end is a ball bearing auxiliary support.There are 5pcs bearings on themain shaft ( 3pcs model 7218 Φ90, 2pcs model 7214 Φ70 ). The lubrication adopts the splash lubrication structure in the box, and the advanced spindle structure adds the perfect process measures ensure that the main drive system has high rigidity and rotation accuracy, and high accuracy retention. The speed range of the machine tool is 80~2200r/min
Feed system: X, Z axis feed adopts the form of direct connection between servo feed motor and ball screw through an elastic coupling. And X shaft ball screw support bearing adopts a high rigidity angular contact bearing with a shaft diameter of 20mm. The Z-axis ball screw is fixed at one end and supported at the other end. The X and Z-direction guide rails are in the form of sliding guide rails. The guide rails are subjected to intermediate frequency quenching, and the hardened layer is uniformly deep to more than 3mm. Hardness up to Above HRC52, the sliding surface of the carriage is covered with plastic, so that the rigidity of the feed system, the friction damping coefficient and other dynamic and static characteristics are at the best status. It has the characteristics of large contact area, high load-bearing capacity, good accuracy retention, and good seismic resistance.
Tail stock: Tailstock The bottom of the taper hole of the tailstock sleeve of the machine tool is equipped with a tool stop block to prevent the tool loaded in the taper hole from rotating. Tailseat relies on a one-way guide rail for lateral movement and is adjusted by screws. Before moving, loosen the locking handle, the pressure plate and the strip screw.After adjustment, tighten again. The tailstock body and sleeve are lengthened to avoid interference between the knife holder and the tailstock. After releasing the lock handle of the tailstock, the entire tailstock moves on the bed rail.
Lubrication system:Lubrication system adopts centralized quantitative automatic lubrication device. Quantitative and automatic for ball screws, slides, bed saddles, etc.Lubricate regularly. The screw bearings are lubricated with grease. The spindle bearing is lubricated with oil in the box.
