Upper and lower arm of the main structure will be designed to place it parallel to the rail of the center, up and down fast movement, will not produce off-center force protection could be the perfect main, jib institutions and mold.Front and rear (Y axis) movement can be minimized when the air pressure, so that arm movement is not smooth or failure Buzhi Yu generated the phenomenon.Parts made of aluminum alloy die casting mold manufacturing, wood technology lightweight, precision accuracy.All air pipes, fittings are imported brands, the wind pipe, a fixed chain alignment direction are not easy to break loose, break and other characteristics.Components, structural design will be adopted for non-oil plant, machinery maintenance easy living longer, without a lot of grease to avoid damage to plastic products.Clean and smooth, lightweight design, high-degree of aluminum alloy, the overall lighter weight, better rigidity.X, Y, Z axis AC servo motor drive, low noise line with Japan THK rails, high speed, quiet, smooth and stable.(Optional add jib, jib with the cylinder drive)
