Hiwin HG Series Linear Rails

The initial winning or losing condition for establishing outstanding quality of linear slide rail is the correct selection of standard models, but the key factor affecting the quality of use is the quality of the linear slide rail device. Even if the correct model of linear slide rail is selected, it will still greatly affect the product life and organizational operation due to poor device quality. Outstanding device quality is based on adhering to the principles and processes of linear slide rail device planning. The following are the planning and process matters that should be noted for linear slide rail devices.

Tighten the positioning screws of the slide rail slightly from the center to both sides in order, so that the trajectory is slightly aligned with the straight device surface. The order can achieve relatively stable accuracy by starting from the central position and pressing towards both ends. After slightly tightening the straight reference plane, strengthen the locking force of the lateral reference plane to ensure that the main rail can truly adhere to the lateral reference plane. Linear bearings are mainly used in automation machinery, such as machine tools imported from Germany, paper bowl machines, laser welding machines, etc. Of course, linear bearings are used in conjunction with linear shafts

Linear guides are mainly used in mechanical structures with high precision requirements. There is no need for an intermediate medium between the moving and fixed components of linear guides, and rolling steel balls are used instead. Due to its adaptability to high-speed motion, low friction coefficient, and high sensitivity, rolling steel balls meet the working requirements of moving parts such as tool holders and drag plates in machine tools. If the effect force on the steel ball is too strong, the steel ball will experience excessive pre load for too long, resulting in increased resistance to the movement of the bracket. There is a balancing effect issue here; In order to improve the sensitivity of the system and reduce motion resistance, it is necessary to reduce the preload accordingly. However, in order to improve motion accuracy and precision persistence, sufficient preload negative numbers are required, which are contradictory aspects. The planning of the rail system strives for a large contact area between fixed and moving components, which not only improves the system's load-bearing capacity, but also enables the system to withstand the impact force generated by intermittent cutting or gravity cutting, widely spreading the effect force and expanding the load-bearing area.

The development of synchronous pulley manufacturing technology is largely reflected in the improvement of precision levels and production power Since the 1970s, the manufacturing accuracy of various synchronous pulleys has generally improved by about one level Some even have levels 2-3 The accuracy of low-speed synchronous belt pulleys has generally improved from 8-9 levels in the past to 7-8 levels. The synchronous belt pulley of the machine tool has been upgraded from level 6-8 to level 4-6 The synchronous belt pulley of the rolling mill has been upgraded from 7-8 levels to 5-6 levels. For small and medium-sized standard synchronous belt pulleys with small modulus, due to the development of high-performance hobbing machines and the improvement of tool materials, there has been a significant improvement in hobbing power. Using multi head rolling cutters, the achievable cutting speed under high feed and conditions is 90m/s. If a superhard rolling cutter is used to machine a quenched and tempered steel synchronous pulley with a modulus of about 3, the excessive cutting can reach 200m/s to improve the gear hobbing power, which is limited by the reciprocating motion of the gear hobbing machine tool. Recently, after developing new structures such as tool unloading, using static pressure bearings, and enhancing the rigidity of the tool holder and column, there has been a significant improvement in power. The stroke count of the new gear hobbing machine can reach 2000 times per minute. The development of low-noise synchronous belt pulley device is a characteristic of synchronous belt pulley planning In order to achieve the miniaturization of synchronous belt pulley devices and improve the load-bearing thrust of existing involute synchronous belt pulleys.
