The method of obtaining position accuracy through one-time installation method in CNC programming/Shenzhen precision carving machine tool

&Nbsp;
The relevant surfaces of parts with positional accuracy requirements are completed and ensured in the same installation of the workpiece, such as the perpendicularity of the outer circle and end face of shaft parts, the parallelism and perpendicularity between holes in the box hole system, and the coaxiality of holes on the same axis< Br/>


&Nbsp& Nbsp& Nbsp; The one-time installation method is generally achieved by clamping with fixtures. A fixture is a device used to hold workpieces (and guide cutting tools). The positioning and clamping components on the fixture can quickly obtain the correct position of the workpiece and fix it on the fixture and machine tool. Therefore, the workpiece positioning is convenient, the positioning accuracy is high and stable, and the clamping efficiency is also high. When positioning with precision reference, the positioning accuracy of the workpiece can generally reach 0.01mm. Therefore, using specialized fixtures to clamp workpieces is widely used in medium, large-scale, and mass production. However, due to the high cost and long cycle of manufacturing specialized fixtures, specialized fixtures are rarely used in single piece and small batch production, and universal fixtures are used instead. When the machining accuracy of the workpiece is required to be high, a combination fixture assembled with standard components can be used, and the components can be disassembled after use.
