Any product has its own advantages and disadvantages, in the use of the process will have advantages and disadvantages, woodworking engraving machine is also the case. The performance of woodworking engraving machine is very important to the linear guide rail. Today, let's talk about the advantages and disadvantages of the linear guide rail of woodworking engraving machine, which can help you better use woodworking engraving machine. The advantages of linear guide rail of woodworking engraving machine are as follows: 1. High positioning accuracy: when using linear slide rail as linear guide, because the friction mode of linear slide rail is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide, but also the difference between dynamic friction and net friction becomes very small. Therefore, when the bed is running, there will be no slippage, and the positioning accuracy of um level can be achieved. 2. Less abrasion can maintain the precision for a long time: the traditional sliding guidance will inevitably cause poor motion precision of the platform due to the countercurrent effect of the oil film, and the sliding time is not sufficient, the wear of the contact surface of the running track seriously affects the accuracy, while the wear of the rolling guide is very small. Therefore, the machine can maintain the accuracy for a long time. 3. Use high-speed movement and greatly reduce the driving horsepower required by the machine: as the friction force is very small when the linear slide rail moves, the bed can move with only a small power, especially when the working mode of the bed is frequent round-trip operation, the power loss of the machine can be obviously reduced. And because the heat generated by friction is small, it can be suitable for high-speed operation. 4. Can bear the load in the up, down, left and right directions at the same time: due to the special bundle structure design of the linear slide rail, it can bear the load in the up, down, left and right directions at the same time, unlike the lateral load that the sliding guide can bear in the direction of parallel contact surfaces. It is easy to cause poor operation precision of the machine. 5. Easy to Assemble and have interchangeability: When assembling, as long as the slide rail supports the assembly surface on the milling or grinding machine table, and according to the recommended steps, the slide rail and slider are respectively fixed on the machine table with specific torque, it can not only reproduce the alarm density during processing. The linear slide rail has interchangeability, and the slider or slide rail God or even the linear slide rail group can be replaced separately, and the machine can regain the guidance of this precision. The disadvantages of linear guide rail of woodworking engraving machine are as follows: 1. Static friction is larger than Compass coefficient, at low speed (1-60 mmmin) It is easy to crawl 2. When used for a long time, if the machine tool is slightly deformed, the running speed will be reduced, which directly affects the production capacity 3. The same motor uses the lower gauge to reduce the use of the drive motor nm and increase a certain load 4. It is required that the attachment surface of the guide rail has high precision and high cost. The surface is easy to rust, which is the advantages and disadvantages of woodworking engraving machine. You can understand that understanding the performance of the equipment can make the use effect better.
