The basic working principle of slotting machine
Slotting machine is a linear motion machine tool that uses the vertical reciprocating motion of the slotting tool to slot the keyway and the hole. The slotting machine, like the planer, also uses a single-edged tool (slotting tool) to cut the workpiece, but the planer is a horizontal layout, and the slotting machine is a vertical layout. Slotting machines have low productivity and accuracy. They are mostly used for processing inner keyways or spline holes in single or small batch production.
Slotting machine operating procedures and safety regulations
The slotting machine is actually a vertical planer, which belongs to the same type as the bull's head planer in terms of structure. The linear reciprocating movement of the plunger in the vertical direction with the ram is the main movement, and the intermittent movement of the workpiece in the longitudinal, transverse and circumferential directions is the feed movement. The production efficiency of the slotting machine is low, the surface roughness Ra of the processing surface is 6.3-1.6 microns, and the perpendicularity of the processing surface is 0.025/300 mm. The main parameter of slotting machine is the maximum slotting length.
The working principle of vertical driling machine!
The power of a vertical driling machine comes from a motor, which drives the motor to rotate through electricity. Therefore, the belt pulley connected to the motor rotates accordingly, and this rotation realizes the speed change through the action of the gears with different transmission ratios on the transmission shaft.
