What are the processing ranges of planing?

Planing plane, vertical plane, step, right-angle groove, inclined plane, dovetail workpiece, T-groove, V-groove, curved surface, machining in hole, rack, etc.

Planing can be carried out on a shaper or planer, and the main movement of planing is variable-speed reciprocating linear movement. Because there is inertia when changing speed, the improvement of cutting speed is limited, and cutting is not carried out on the return trip, so the production efficiency of planing is low. However, the machine tools and tools needed for planing are simple in structure, convenient to manufacture and install, easy to adjust and universal. Therefore, it is widely used in single piece and small batch production, especially when processing long and narrow planes.

Extended data

The ram is a planer with a planer for linear reciprocating motion. Because the tool rest at the front end of ram looks like a bull's head, it is also called a shaper. Planing machine is mainly used for planing plane, forming surface and groove on small and medium-sized workpieces in single piece and small batch production. The main motion of small and medium-sized shaper is mostly driven by crank-rocker mechanism (see crank-slider mechanism), so the motion speed of ram is uneven.

Large-scale molding machines mostly adopt hydraulic transmission, and the ram basically moves at a constant speed. The return speed of the ram is greater than the working stroke speed. The productivity of the shaper is very low, because it is processed by a single-edged planer and does not cut when the ram returns. The main parameter of machine tool is the maximum planing length.

The planer moves horizontally and linearly through the ram with the planer. The tool rest can rotate at a certain angle in the vertical plane and can be manually fed. The worktable moves horizontally or vertically intermittently with the workpiece, and is often used for machining planes, grooves and dovetail surfaces. Copying shaper is to add copying mechanism to ordinary shaper to process molding surface, such as turbine blade.

The ram and slide seat of the mobile shaper can also move on the lathe bed (horizontal) or vertical column (vertical), which is suitable for planing the local plane of extra-large workpieces.
