Development of high-precision technology (1) "transition curve" optimal design. Japanese scholars found by experiment ball rolling linear guide Gang circulation circuit design directly affect the feed motion of the high frequency vibration and dynamic friction changes, changes in the frequency and dynamic friction ball diameter about the linear guide bearings, indicating that the ball in Working out of the raceway produced a shock friction. The author of the transition curve in the form of rolling linear slide rail circulation loop deputy were discussed at a given clearance methods, ball circulation loop with arc-shaped concave cylindrical surface of the trench, the centerline of each cylindrical surface (ie, the center of the track wheel line) using multi-stage single, double circular spline, and its optimization. Gang ball so smooth, continuous load changes without the mutation, reducing the impact, thereby reducing the dynamic friction high-frequency vibration amplitude, for improving the precision linear feed accuracy is important 1. Linear Rolling Guide noise problems have been better solve Yamata et al prove the main reason for the noise rolling linear guide produced by the body and end caps rolling, rolling collision Road. For the sound pressure level in the range of 100 ~ 20 000HZ, by loading the lighter ceramic balls (Si5 N4) can be reduced. When measured by the movement speed is within 0.3 ~ 1.17m / s range, noise ball rolling body is 60.0 ~ 76.9dB, and the noise of the ceramic balls 55 ~ 71dB, the average noise is 4.5 dB. 2. The face of the green environmental protection requirements of semiconductor, LCD manufacturing equipment for green environment is extremely demanding, under such circumstances, rolling linear guide linear guide using a vacuum fluorocarbon lubricant, because the amount of fluorocarbon lubricant dust occurs rarely . But fluorocarbon lubricant durability and rust resistance is not high linear guide lathes, high-speed operation resistance increases, sealed and lubricated parts using low dust due to the above reasons lubricants and KI series vacuum lubricant composition can be equally characteristics. In order to achieve environmental protection requirements and the requirements of a wide variety of linear guides, antirust ability to improve is very important. For example, stainless steel guideways, using martensitic stainless steel, having the same general standard guideways rated load and other functions. To prevent rust and light reflection on the guideway must be surface treated. From anti-rust performance, durability, and cost aspects, recommended black chrome plated electrolytic rust-proof black coating surface treatment technology. You can also use low-temperature deposition method coated with fluorinated fluorocarbon resin coating, anti-rust properties make further improvement can be widely used in the pharmaceutical, food machinery.
