Machine  structure

1、Bed

The bed of the machine is casting by resin sand technology, with reasonable internal rib layout, and the width of the bed rail is 600mm. The bed is an integral ground-type one-piece casting bed with high overall rigidity. Ultrasonic quenching is adopted, and the saddle and slide sliding rail surface are plastic-coated, so that the rigidity of the feed system, the friction damping coefficient and other dynamic and static characteristics are in the best state. Since the dynamic and static friction coefficients are close, the occurrence of low-speed creeping phenomenon is reduced; the machine tool has good rigidity, high resistance to vibration and deformation, and can enable users to obtain higher processing accuracy and increase the speed of rapid movement, and obtain higher production efficiency.

2、Main drive system

The main transmission system adopts a mechanical three-speed manual transmission structure as standard, the spindle through-hole diameter is φ105, and the spindle speed is 40～125 rpm; 110～350rpm; 290～950 rpm. The spindle lubrication adopts an external oil tank structure. Through the special structural design of the tank cover, the traditional point lubrication is upgraded to shower lubrication, which is more sufficient. While lubricating the bearings and gears, it takes away most of the heat in the box, reducing the influence of the spindle heating on the overall accuracy of the head box.

3、Feeding system

X-axis ball screw

The support form adopts the form of one end fixed and the other end supported. This support method allows the screw to extend freely without longitudinal bending when the screw is extended due to the increase of temperature during operation.

Z-axis ball screw

In order to compensate for the elongation of the screw caused by the increase in working temperature and to ensure the positioning accuracy of the screw and the system rigidity of the ball screw during use, the screw is pre-stretched and pre-loaded

4、Tool holder

The tool holder is equipped with Changzhou Hongda LDB4-157/300 vertical 4-station electric tool holder as standard, which has high rotation accuracy and good rigidity. A horizontal 6/8-station electric tool holder is also available as an option.

5、Tailstock

Standard manual tailstock, optional hydraulic tailstock, Morse 6 taper hole, sleeve diameter φ120mm, stroke 250mm.

When the hydraulic tailstock is selected, the hydraulic tailstock sleeve is hydraulically driven, which saves time and effort. It also has a moving and positioning interlocking device to prevent misoperation and provide safety assurance for users during operation.
