Wan Jun Chi Mechanical and Electrical Equipment Co., Ltd.: If the solemn commitments to You: The company's products are authentic, fake a lost decade. Your trust is our responsibility! HIWIN linear guide advantages and characteristics: 1. positioning accuracy linear guide as a linear guide, linear guide way due to friction rolling friction, not only sliding friction coefficient down to 1/50 of the guide, dynamic friction and static friction the gap also becomes small. So when the bed running time, there will be no slip phenomenon can reach μm-level positioning accuracy. 2. Wear less able to maintain a long tradition of precision slide guide, inevitably due to the adverse effect of greasy countercurrent kinematics accuracy, and because of inadequate lubrication during exercise, leading to wear the orbit of the contact surface, significantly affect the accuracy. The rolling guide wear is very small, so the machine can maintain precision long time. 3. For high-speed motion and significantly reduce friction due to linear guide movement is very small, only a small force will make the bed running, especially running back and forth to the regular work of the BED drive the required horsepower machine , more significantly reduce the amount of power consumption machine. And the heat generated by friction because of its small, suitable for high-speed operation. 4. At the same time withstand the load due to the vertical and horizontal directions of the linear guide special beam system design, which can withstand the load up and down direction, unlike the sliding guide in a direction parallel to the contact surface can withstand lateral load is light, easy to cause Machine running bad accuracy. 5. easy to assemble and as long as the mounting surface milling or grinding rails of the bed table, and in accordance with the recommended steps of assembling the rails with interchangeable sliders are fixed to a specific torque on the machine table, which can reproduce during processing High precision. Conventional sliding guide, running track shall be scraped, both cumbersome and time-consuming, and once the bad machine precision, it must once again scraping. Linear guide interchangeable, respectively replace the slider or even a linear guide rail group, the machine can regain the high precision guide. 6. Lubrication simple structure if insufficient lubrication slide guide, will result in direct contact with the metal surface friction loss bed units, while the sliding guide to adequate lubrication is not easy, you need the proper position BED oil drilling. Linear guide devices already on the slider nozzle directly to the grease gun into the grease, also put special oil pipeline connecting pipe fittings, automatic machine lubrication oil.

Linear guide rated load: 1. Basic static load rating (1) Basic static load rating (C0) of the definition of linear guides in rest or in motion, if subjected to excessive load, or subject to a large impact load, it will cause beads Road the contact surface and the ball permanent deformation of the Council; when the permanent deformation exceeds a certain limit, will impede the smooth movement of the linear guide. The basic static load rating is permissible permanent deformation of the limit load. By definition: under the direction and size of the load of the same state, subject to the maximum stress in the contact surface, the surface of the track ball and beads total permanent deformation of the ball just ten thousandth the diameter of a stationary load. Basic static load rating values ??set out in the specifications of the size of the table; the user can refer to the table to use the appropriate linear guide, but it must be noted that the maximum static is selected linear guides during operation suffered its basic static load should not exceed rated load. The definition (2) Allowable static moment (M0) when the slider by maximum stress ball to achieve the above definition of the static load rating, this time hosted by the slider called static torque rated torque. MR is the linear guide movement, MP, PY defined three directions (3) Static safety factor when the linear guide used in slow motion or high actuation frequency is not the situation, consider the static safety factor. Depending on usage, calculate the static load safety factor to be considered different, especially when there are guide by the impact load, need access to a large safety factor. fSL = C0 / P or fsm = M0 / M fSL: Static safety factor fSM: Static safety factor (moment load) C0: Basic static load rating (kN) M0: Static permissible moment (kN · m) P: Working Load ( kN) M: Static moment load (kN · M) 2. The basic dynamic load rating (1) The basic dynamic load rating (C) of the definition of basic dynamic load rating for linear guide rail to bear the load and make the life of the rolling motion of the calculation. Which is defined in the load direction and magnitude of change of status, the rated life of linear guide when the maximum load 50km, this value set out in the specifications of the size of the table, the user can thus predetermined value estimated by the choice of rated life linear guide. Silver linear guide life: 1. life when subjected to a load and linear guide for sports, track and ball bead surface due to constantly exposed to cyclic stress effect, a rolling fatigue but reach the critical value, the contact surface will begin to produce fatigue damage and in the sub-surface of the sheet occurs scaly flaking, this phenomenon is called surface stripping. Life is defined road surface bead and ball due to material fatigue that always run away from the surface until release. 2. The rated life of the linear guide life, with a great dispersion, even if the same number of manufactured products, used in the same state of motion, life will be different; this mostly blamed on fatigue inherent material properties change. Therefore, the definition of life linear guide, generally rated life as a benchmark; which is defined as: the number of the same product, one by one run under the same conditions and rated load, 90% of the surface delamination occurred and can never achieve total Run away. 3. Life of life calculated linear guides actually incurred due to different workloads, you can use the basic dynamic load rating and workload calculate the life of linear guides. 4. Pearl Road contact surface hardness life factor (1) Hardness factor (fh) linear guide to some of the requirements of the case depth hardness HRC58-62, if the hardness value can not meet the requirements of the standard will reduce the rated load of linear guide and life, this time the dynamic and static load rating multiplied by the size of the table column values ??corresponding hardness factor. HIWIN linear guide hardness HRC58 played the requirements are all over, so fh 1 (2) Material Temperature Coefficient (ft) linear guide system temperature will affect the rated load when the temperature is higher than 100 ° C and the use of linear guides life will be reduced, then the dynamic and static load rating multiplied by the size of the table column values ??corresponding temperature coefficient. Because some parts are plastic material less heat, it is recommended to use the temperature should be below 100 ° C. (3) Load factor (fw) lubricant selection guide commonly used lubricants are oils and greases, lubricants slide rail. Rolling guide supporting more lubricated with grease. Its advantage is not leaking, do not require frequent refueling; drawback is that wear dust into the rail, so the protection requirements high. Easily contaminated and difficult to guard the place, available lubricating oil. One important way to guard rails to prevent or reduce the side rail of wear and tear, is the guide for protection. According to statistics, there are guard rails and reliable than the exposed rail wear can be reduced by about 60%. Commonly used protection methods are the following: good scraper type heat capacity, but only exclude larger durum. You can remove fine dust, but also has a good range capabilities. Good heat resistance, protective ability and good lubricity. Although the structure is slightly complicated, applications are still a lot. Retractable soft bellows guards, usually made of leather, canvas or leather, simple structure, can be used for high-speed rail. The disadvantage is not resistant to heat. Such protection devices are used for grinding machine and precision machine tools, such as rail grinders. But not for red hot chips lathes and milling machines and so on. Cover each layer by steel plate, heat resistance, high strength, rigidity and long life. The guards used for large-scale and precision machine tools, such as gantry machines, CNC machine tools and coordinate boring machine. Improve the wear resistance of the rail measures to improve the wear resistance of the basic idea from a design point of view is: strive for wear; if you can not avoid chafing strive for less wear, uniform wear, and the wear and tear can be compensated in order to improve life. The reason for abrasion wear is in direct contact with the surface and relative movement at a certain pressure effect. With the proviso that it is not worn in direct contact with the surface is not at the time of relative movement, no relative motion upon contact. One way is to make the lubricant to the friction surface is completely separated. Such as hydrostatic guideway, hydrostatic bearings or other static deputy. For less wear and tear for no wear can only be done in rare and special circumstances. In most cases only for less wear and tear to extend a deadline. Lower pressure used to increase the contact surface and guide the way to reduce the load to reduce the pressure. Improve straightness and surface roughness of the guide surface refinement, may increase the actual contact area. Unloading rail is to reduce the use of rail load, a good way to reduce the pressure. The friction properties change instead of using a rolling slide vice deputy, can reduce wear. Ensure adequate lubrication to avoid friction or semi-dry friction sliding friction, but also can reduce wear. The correct choice of friction material and heat treatment appropriately selected pairs of friction material and heat treatment can increase the resistance to wear. For example, the support rails hardened, the movable rail surface mount plastic soft zone. Strengthen protection strengthen protection, to avoid dust, chips, and other debris into the friction wheel is effective measures to improve the wear resistance of the rail. For uniform wear work wear is uniform deadline parts greatly affected. Such as bed rails, if the wear is uniform, little general impact on the machining accuracy, and can be compensated. The main uneven wear two reasons: the uneven distribution of pressure in the friction surface; the use of different opportunities for each part. Uniform wear for the following measures: 1. strive to make the friction surface pressure evenly distributed, for example, to guide the shape and size of the concentrated load as symmetrical as possible; 2. minimize the torques and overturning moment; to ensure the table, apron, etc. the support member has sufficient rigidity; 3. friction in the opportunity to use the entire length of the uneven hardness that one should be higher, such as hardness lathe bed rails should be higher than the saddle rail hardness.
