Overview

The CNK800/1500 high-precision CNC lathe adopts resin sand integral casting and aging treatment for the bed legs, and ultrasonic quenching for the guide rails. The main sliding surface of $r $n adopts plastic pasting technology to eliminate crawling and improve accuracy retention. The $r $nX and Z-direction screws both use a three support mechanism. The $r $n spindle structure adopts a typical three-point support structure, and the spindle has high stiffness; The bearing adopts high-precision spindle special bearings from Harbin Bearing Factory, which enables the spindle to have high rotational accuracy. The main transmission is a manual 3-speed continuously variable speed system with a speed range of 40-950r/min; The main transmission gear pairs have undergone quenching and grinding treatment.

Advantages of machine tools

1.lathe tailstock、dragManual scraping and grinding are carried out between the joint surfaces of the board, and the whole machine is tested using a laser interferometer to effectively ensureZaxis.XAxis positioning accuracy, repeat positioning accuracy, reverse clearance, and machine tool stability.

2.The machine tool is made of high-strength cast iron, with special materials such as copper and chromium added. The width of the bed guide rail is600mmThe bedBody guide rail quenching hardnessHRC50 or above，Effectively improved the wear resistance and stability of the machine tool.

3.The machine tool adoptsNanjing AndyCentralized lubrication, headboard boxOil is supplied by the oil pump, and the bearings inside the circulation headboard box are circulatedThe gear and other parts, the motion guide rail, and the ball screw are lubricated with centralized oil supply by a lubrication pump. The left and right brackets and tailstock of the ball screw support part are manually lubricated with oil，In response to the hot weather in the south, the cleanliness and heat dissipation characteristics of the headboard are ensured, effectively extending the service life of the bearings and gears.

4.The machine tool spindle adoptsHarbinbearing, spindle through-holeφ104mmThe machine tool gears are precision ground, effectively improving gear hardness and reducing machine tool noise.

5.The machine tool adoptsSanhe Sheng, Binzhou, Shandongball screw，ZAxial ball screw,XThe axial ball screw adopts a stretching structure, which improves the accuracy of machining the outer circle and inner hole dimensions of the workpiece.

6.The machine tool adoptsChangzhou YizheFour station electric knife holder without lifting.Knife handle size:40x40mmOptional six station electric knife holder.
