CNC Machining has become more and more widely used in today's machinery manufacturing and processing industry. In particular, economical CNC machine tools are widely used in some enterprises, especially small and medium-sized enterprises, due to their wide range of processing, high efficiency, stable quality, and low prices. The application and development.
However, in popularization and application, problems such as long preparation time, large processing errors, accidents or the like are often caused due to improper use or process design, which brings many inconveniences and psychological pressure to operators. In fact, the economical CNC machining method is very convenient and safe to use if used well. The following describes the corresponding methods for several common problems in processing. 1 Use proper tool setting method After the tool is installed, the tool must first be set to determine the starting point before executing the machining program. The countersink is often a headache for the operator (economical CNC without self-test device), time and labor, especially when multi-tool processing, it is necessary to measure the tool compensation value. In general, the common tool setting methods are: Jog mode Press and hold the jog key on the control panel, touch the tool tip on the surface of the workpiece (in both X and Z directions to jog twice), and clear the counter. , and then back to the initial position to be set (X, Z design initial value), and then cleared to get the initial position of the knife. The initial position of each knife is determined in turn, and after the trial machining, it is adjusted to an accurate design position (starting point). This method does not require any auxiliary tools. It can be operated at any time, but it takes a long time. In particular, the tool must be readjusted every time the tool is ground. This method is suitable for simple process or initial installation and debugging. The self-test device is adopted for the tool setting tool that is equipped with the tool setting method. However, the operation is complicated and it still takes a certain amount of preparation time. Suitable for multi-knife measurement. With the use of numerically-controlled tools, the tool positioning after initial positioning, after a certain period of time, wear occurs and needs to be sharpened, and the position of the tool tip changes when the ordinary tool is sharpened and refitting. The characteristics of CNC cutters are the high precision of the cutters, and the repositioning precision of the blades after indexing is about 0.02mm, which greatly reduces the time for the cutters. At the same time, the blade surface is coated with a wear-resistant layer (SiC, TiC, etc.), making it durable. The degree is greatly improved (3 to 5 times), but the cost is higher.
