What are the precautions of shallow rail CNC lathe in machining

Characteristics of oblique rail CNC lathe
1. The biggest feature of the inclined rail CNC lathe is to save the floor area of the machine tool. The change of the feed cutting direction from the original horizontal or inclined feed to the top-down turning feed. Such a change reduces the distance between the workpiece and the operator, which not only makes it easier to see the turning situation, but also makes it easier for the operator to load and unload the tool.
2. The inclined rail CNC lathe increases the space for chip removal during workpiece turning, and places the traditional guide rails under and behind the workpiece above the workpiece, making chip removal more smooth and avoiding the accumulation of iron chips.

Precautions for the selection of inclined rail CNC lathe
1. Model selection
In the processing of boxes, cavities, mold parts, etc., the processing of CNC milling machines and machining centers with the same specifications can meet the requirements, but the prices of these two kinds of machine tools differ a lot, so in the mold processing, only the process of changing tools very frequently will choose to use machining centers, and generally CNC milling machines will be used.

2. CNC system selection
When purchasing inclined rail CNC lathes, the same machine tool can be configured with a variety of CNC systems, which can be used for open CNC systems with NC embedded in PC structure or soft structure. The CNC software of this kind of system is completely installed in the computer. The hardware part is only the standardized general interface between the computer and the servo drive and the external 1/0.
In addition, in the CNC system, there are many optional functions in addition to the basic functions. Users can follow the requirements of processing workpiece, measurement requirements, programming requirements, etc. in the process of processing, especially the NDC function of real-time transmission, etc.

3. Selection of accuracy
The choice of accuracy grade of oblique rail CNC lathe depends on the machining accuracy of typical parts. Generally, the items of accuracy inspection of CNC machine tools include the accuracy of repeated positioning of single axis and the roundness of test pieces processed by more than two axes. The positioning accuracy and repeated positioning accuracy are the comprehensive accuracy of the moving parts of the axis.

At present, the software part of our NC system in production has rich error compensation functions, which can stably compensate the system errors of all links on the feed transmission chain. Just like the pitch error and cumulative error of the lead screw, the pitch compensation function can be used to compensate.
