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.
