How to choose the right machine tool?

Numerical control lathe in the process of high-speed processing, if you want to improve the efficiency of its processing, then, choose the right tool is relatively important, the right tool can improve the processing efficiency of numerical control lathe. For the choice of cutting tools, the main consideration should be CNC machine tool processing capacity, process content, as well as various factors of workpiece materials.

For numerical control lathe, the choice of cutting tool requires not only high abrasion resistance, enough toughness and strength, but also has high hardness, high heat resistance and good process performance, at the same time also require size stability, adjust the installation more convenient, so you should use new material with high quality manufacturing nc machining tool, and the need to optimize the parameters of the cutting tool, Mainly make the size of the tool and the workpiece surface size and shape to be processed.

First, you need to choose the right and appropriate tool.

In the process of numerical control lathe machining, metal cutting tool's role is particularly important, for cutting tool manufacturing materials have to has high wear resistance, heat resistance and high hardness, but also has enough strength and toughness, and good thermal conductivity and manufacturability, and also has a good economic performance, if too high nor appropriate. In the process of selecting tools, we should meet the processing requirements of parts under the premise of the larger diameter of the tool as far as possible, its strength and toughness is better. In the same process, the number of selected knives as little as possible to reduce the number of knife changes. In the selection of cutting tools as far as possible to choose general standard cutting tools, do not choose or use less special non-standard cutting tools.

Two, to reasonably determine the appropriate knife point.

The tool point is mainly used in the processing of parts in the machine tool, tool relative to the starting point of the workpiece movement, also known as the starting point of the program or referred to as the tool point. The selection of knife points should strictly comply with the following points: convenient for digital processing and simplified programming; It is easy to find the right need on the lathe, and the processing is convenient for inspection. The resulting machining error needs to be minimal. The position of the knife point can be selected on the workpiece, of course, you can also choose outside the workpiece, such as fixture or lathe, but it must have a certain size relationship with the positioning datum of the part. The knife point should do its best to choose on the design benchmark or process benchmark of the parts, such as the workpiece with hole positioning, you can choose the center of the hole as the knife point. The position of the tool needs to be aligned with this hole, so that the position point and the tool point coincide. In this way, it can better improve the efficiency of the knife, so as to ensure the quality of machine processing.
