With the development of numerical control technology, the hydrostatic bearing is also widely used in machining centers, CNC machine tool spindle. YTO AG first engine plant, there are many static pressure and static pressure diamond grinder boring head, carried out some exploration and try to repair, and gained experience film feedback restrictor. Feedback throttle film bearing stiffness is great, but the machine in operation often appear to hold tile, brushed, lost pressure and so on. The most critical feedback film is a film, in practice considered, bearing locking, napping is mainly due to: ① film plastic deformation due; ② feedback slow. When the external load mutation, did not react when the film surface grinder specifications have been rubbing the shaft and tile; ③ film fatigue. Film using a long time, fatigue deformation, the equivalent of changing the feedback parameters. Grinder manufacturers, the price of second-hand grinder, used surface grinder surface grinder models, used cylindrical grinding machines, surface grinder manufacturers, surface grinder price - choose Hengda NC, believe your choice is wrong. Increasing the thickness of the film and use some of the material fatigue, can receive good results. Generally rigid membrane, pre-load, reserve gap method. Specific practices are: the 1.4mm thick film to 4mm thick rigid film, the inferior vena pad 0.05mm thick aluminum foil, so that the spindle is adjusted to the desired position than 0.05mm high position. The purpose is to force when the spindle (wheel weight, cutting force) after, just return to the ideal center. Then, as we explain what Hengda CNC surface grinder causative survey tool. Surface grinder, rectangular surface, arbitrary angle, such as the cylinder end. The following outlines the main surface grinder micrometer causative approach: First, surface grinder piece of regulation 1 micrometer, block the regulation required for the first Grab (normal size block gauge the number of 1-3, unless otherwise use three dimensions above the block gauge). 2, the control block gauge hurt consumption on tolerance table. 3, the block gauge faces two Guangliu wipe clean, then two blocks Push patchwork regulation, first crosswise, then rotate into a parallel, stick together, when you want to have a word stick sticking out. 4, the selected block gauge the value of the amount of size, to be very close, less than 0.005 μ. Second, the surface grinder of micrometer dial 1, each small grid scale is 0.002mm. 2, the most correct causative range of ± 0.02mm, that is, in the zero surface grinder, left ten grid, right ten grid, fitted sheet and as a member in a vertical plane tilt angle of 30. 3, check the zero position, if a small block gauge, hands on the right to play, otherwise the left. 4, the dial can be rotated on the table is being used to survey the zero position. 5, the hands of the head, you can use 0.4mm and 1.0mm, 0.4mm needle amount, the ladder is less than 1.00mm, less than 1. Slope, 1.0mm needle is greater than the amount of the ladder 1.0mm. Third, surface grinder percentage of micrometer-foot-1, the percentage of the lateral foot scale is a grid of 0.5mm, 0.01mm vertical scale as a grid. 2, in the amount of size, the first to take the first few flat transverse scale surface grinder prices, accurate to one decimal place, look at the vertical scale data, subject to the zero scale, whichever is the corresponding data.
