What is the difference between analysis precision boring and solutions are the main reasons. Poor precision boring reasons: 1, the boring knife block edge wear size changes as boring knife block between positioning surface dirt. 2, reamer diameter choose wrong, wrong choice of cutting fluid. 3, the cutting depth did not grasp the fine boring. Poor precision boring solution: 1 exchange qualified boring boring knife block XingYang large parts machining, remove dirt reinstalled. Select the appropriate diameter reamer hinge streets after 2 ,. test boring processing firms, cutting fluid exchange. 3, adjustment of the cutting depth. Single-column coordinate boring: the main spindle drive tool for rotating movement, quill feed for axial movement. Double-column coordinate boring: Install the tool spindle primary campaign, the workpiece mounted on the table with the table longitudinally along the rail bed straight. Horizontal coordinate boring: Workbench can do rotary motion in the horizontal plane, the feed motion can be moved or axial movement of the spindle is achieved by Longitudinal. Although the same coordinate boring, but their methods of operation and precision machining are some differences, if you do require high precision machined products, then you choose the coordinates of the horizontal coordinate boring boring, so boring during processing time to choose according to their needs.
