Planing and processing of hexahedral parts

hexahedral parts require that the opposite side is parallel, and the adjacent side is also required to be at right angles. Such parts can be milled or planed. The machining procedure shown in Figure 1 is generally used for planing hexahedron

processing procedure:

the first step is generally to plane out the large surface 1 as the fine base surface (Figure 2a)

the second step is to use the processed large static arc height: development cooperation mode and specific product face 1 as the reference plane to stick to the fixed jaw. Place a round bar in the middle between the movable jaw and the workpiece, clamp it, and then process the adjacent surface 2 (Fig. 2b). The perpendicularity of face 2 and face 1 depends on the perpendicularity of the fixed jaw and level. Aoshengde has great development space in the Chinese market. A round bar is placed between the movable jaw and the workpiece in order to concentrate the clamping force in the middle of the jaw, so that the face 1 can be reliably attached to the fixed jaw

step 3: put the machined surface 2 downward, and make the base surface 1 close to the fixed jaw in the same way as above. When clamping, gently tap the workpiece with a hammer to make face 2 close to the flat tongs, and then face 4 can be machined (Fig. 2C)

the fourth step is to process surface 3, as shown in Figure 2D. Put face 1 on the parallel sizing block, and the workpiece is directly clamped between the two jaws. When clamping, it is required to gently tap with a hammer to make the surface 1 stick to the sizing block

measures to ensure the accuracy of hexahedral planing:

(1) check the accuracy of the flat tongs themselves (Figure 3) and install them on the workbench reasonably

(2) when the processing requirements are high, the rough and fine planing should be separated. First roughly plane all sides, leaving a fine planing allowance of about 0.5mm on each side. Use a fine planer when planing

(3) correctly select the processing datum, and take the relatively flat and large blank surface as the rough datum to process a flat plane, such as plane 1 in Figure 2A. The subsequent processing takes this plane as the datum for clamping and measurement

(4) press the machined plane 1 close to the fixed jaw, clamp it between the movable and workpiece with a round bar, and plane the adjacent plane 2 (as shown in Figure 2b)

(5) press the machined plane 2 of the workpiece close to the bottom surface of the jaw, press the reference plane 1 close to the fixed jaw according to the same clamping method above, and plane plane 4 (as shown in Figure 2C)

(6) clamp the workpiece as shown in (Figure 2D) and plane 3

(7) the planing of the other two faces of the hexahedron is also carried out after the plane 1 is close to the fixed jaw and clamped in the same way. (end)
