1. Straight guide rail
The new rail system makes the machine tool achieve fast feeding speed. Linear guide rail is the same as flat guide rail. In order to ensure the precision of the machine tool, a small quantity of excavator with a bed or column is essential. There is no intermediate medium between the moving components of the linear rail and the fixed component, and the rolling steel ball is used. Because rolling steel balls are suitable for high speed exercise, small friction coefficients and high sensitivity, to meet the working requirements of movement components, such as machine tool blade, trailer, etc.
The working time is too long and the steel ball begins to wear, and the preload acting on the steel ball is weakened, resulting in the reduction of the effort of the working components of the machine tool. If you want to maintain the original accuracy, you need to replace the rail bracket and even modify the guide rail. Whether the rail system has a pre-loading effect. The accuracy of the system was lost.
2. Straight roller guide rail
Linear roller rail system is a combination of graphic guide rails and straight roller rails. The advantage is that the contact area is large, the charging load is large, and the sensitivity is high. From the tail of the bed, the bracket and roller are placed on the top and side of the graphic guide rail. Pre-load on the side of the support.
The working principle of the corner plate is similar to the oblique iron, and the weight of the working parts acts on the upper surface of the support. Since the pre-added load on the rail system is adjusted, the loss of the corner is compensated, this function is widely used on the medium or large machine tool, because it has sensitive response to CNC instruction, large with large load, straight lines, straight lines roller rail system can withstand high-speed operation than traditional graphics drivers and improve the performance of machine tools.
3. Steel rail
The most commonly used rail on the machine tool is inlaid with steel and its use has a long history. The steel rail is a fixed component of the guide rail system and its cross section is rectangular. It can be installed horizontally on the bed of the machine tool, and it can also be cast in one with the bed, which is called inlaid or overall steel. Steel type guide rails are made of steel and harden and set.
The hardness is more than 60 degrees of Lowl hardness, and the rails inlaid with screws or adhesive (epoxy resin) are placed on the surface of the machine tool or scraping columns. This form is convenient and simple to replace and replace, which is very popular with maintenance workers.
4. Slide Guide
The development of traditional guide rails first manifests itself in the form of components and sliding rails. Hydraulics are widely used in many railway systems.
Static guide rails are one of them. friction of moving components. Static pressure guide rails are extremely effective for large loads and have a compensating effect on eccentric loading.
Another form of guide rails using oil is a dynamic medium guide rails. Direct contact, the advantage is saving hydraulic oil pumps.
Air can also be used for the middle between the movement of the movement and the guide rail.
