RF系列立式数控车床主要以大、中型加工件为对象，以实现强力、高精度、高生产效率加工为目的，以高刚性 、运行平稳流畅、并能持久保持高精度为基本方针而设计的产品。该款是针对汽车轮毂加工专用机型。具有以下结构特点
1、机床为整体式箱形结构结构，矩形截面立柱，具有刚性好，可耐重切削并长期保持高精度的特点。
2、回转刀架在滑鞍上沿纵、横向导轨移动，导轨采用直线滚柱导轨，移动轻便，没有爬行，动作灵活，定位准确， 　 可长期保持精度。纵向运动配有有自重平衡装置，其动作灵活、迅速且准确。
3、主轴直径粗，轴承结构刚性好，可进行高精度强力切削。
4、各种手动、数控、强电按钮和CRT装置全部集中在摆臂式面板上，提高了操作性。
5、采用具全封闭式护罩；排屑器为后排型。

RF series vertical CNC lathes are mainly designed for large and medium-sized machined parts, aiming to achieve powerful, high-precision and high-efficiency machining, and taking high rigidity, smooth operation and long-lasting high-precision as the basic policy. This model is a special model for automobile hub processing. It has the following structural features

1. The machine tool is an integral box structure with rectangular section columns. It has the characteristics of good rigidity, heavy cutting resistance and long-term high precision.

2. The rotary tool rest moves along the longitudinal and transverse guide rails on the sliding saddle. The guide rail adopts a linear roller guide rail, which is portable, free of crawling, flexible, accurate positioning and can maintain the accuracy for a long time. Longitudinal movement is equipped with self weight balance device, which is flexible, rapid and accurate.

3. The diameter of the main shaft is large, and the bearing structure is rigid, which can be used for high-precision and powerful cutting.

4. Various manual, numerical control, strong current buttons and CRT devices are all concentrated on the swing arm panel, which improves the operability.

5. Adopt totally enclosed shield; The chip conveyor is a rear row type.
