Large gantry computer gong processing is a common processing project in machinery, especially large-scale machining. There are still many technical problems in large-scale CNC processing. What requirements should be observed in terms of machining and technology?
Requirements for processing large gantry computer gongs
1、 Remove the oxide scale on the surface of the parts, and the machined surface of the parts shall be free of scratches, scratches and other defects that damage the surface of the parts. The tolerance of unmarked shape shall meet the requirements of gb1184-80, the standard tolerance of unmarked length shall be ± 0.5mm, and the casting tolerance zone shall be symmetrical with the basic standard equipment of blank.
2、 The rolling bearing of the device is allowed to be heated by oil for hot installation, and the oil temperature shall not exceed 100 ℃. Sealing filler or sealant is allowed to be used in the hydraulic system of the device, but it shall be avoided to enter the system. The parts and components entering the device must have the certificate of inspection before the device can be installed.
3、 Parts must be cleaned before installation, and there shall be no burrs, burrs, scale, rust, chips, oil, colorant, dust, etc. Before installation, recheck the main matching standards of parts, especially the interference matching standards and relevant accuracy.
4、 During the use of large gantry computer gong processing equipment, parts are not allowed to be knocked, bumped, scratched and rusted. When fastening screws, bolts and nuts, it is forbidden to use improper screwdriver and wrench for impact or use. After fastening, the screw groove, nut, screw, bolt head, etc. shall not be damaged due to large CNC processing. For fasteners that are tightened according to the specified torque requirements, a torque wrench shall be selected and tightened according to the specified tightening torque.
