Boring processing characteristics: processing a workpiece does not move, so that the tool moves, the tool center alignment hole center, and rotation of the tool (main motion). (1) Horizontal Boring boring is the most widely used one. It is mainly drilling, boring accuracy up to IT7, the surface roughness Ra value 1.6-0.8um. ??Main parameters of horizontal boring spindle diameter. (2) coordinate boring jig borer is a high precision machine tools. Its structure is characterized by a coordinate position precision measuring device. Coordinate boring can be divided into single-column coordinate boring, boring and horizontal double-column coordinate coordinate boring. Single-column coordinate boring: the main spindle drive tool for rotating motion Erqi Boring, quill feed for axial movement. Features: simple structure, easy operation Jinshui Boring, especially suitable for machining parts, precision plate-hole, but it's less rigid, so this structure is only suitable for small jig boring. 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. It's good rigidity, large-scale coordinate boring currently are using this structure. The main parameters for double-column coordinate boring work surface width. 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. Its higher precision. (3) Diamond Boring: Features is a small amount of feed and high cutting speed machining Boring, thus machined workpiece with high dimensional accuracy (IT6) Hui Boring, surface roughness can be 0.2 microns. Coordinate boring boring mainly for high-precision holes and have the exact coordinates of precision holes. Can be performed with high precision milling. Also used to work crossed and engraved lines, as well as measurements of precision parts such as the model and precision parts. Coordinate boring hole machining coordinate positioning accuracy of up to 0.004 ~ 0.01mm, the surface roughness of the machined surface is less than Ra0.8μm.
