Know "planer"

A planer is a machine that uses planers to plan the plane, groove, or forming surface of a workpiece. The planer is to make the relative linear reciprocating motion between the tool and the workpiece to achieve the purpose of planing the surface of the workpiece. The reciprocating motion is the main movement of the planer. In addition to the main movement of the machine tool, there are auxiliary movements, also known as feed movement, the planer's feed movement is the intermittent movement of the table (or planer).

Planers can be planed for horizontal planes, vertical planes, slopes, curved surfaces, step surfaces, dovetail-shaped workpieces, T-slots, V-grooves, as well as planing holes, gears, and racks. If the planer is properly modified, the planer's scope of application can be expanded.

The planer has a high efficiency when it is used to shave narrow and long surfaces. It is suitable for medium and small batch production and maintenance workshops. A planer is a linear motion machine that uses a planer to plan the plane, groove, or forming surface of a workpiece. Using a planer tool, the tool is relatively simple, but its productivity is low (except for a long and narrow machined surface), so it is mainly used for single-piece, small-batch production and mechanical workshops. It is often replaced by a milling machine in mass production.

Cutting principle

The planer is to make the relative linear reciprocating motion between the tool and the workpiece to achieve the purpose of planing the surface of the workpiece. The reciprocating motion is the main movement of the planer. In addition to the main movement of the machine tool, there are auxiliary movements, also known as feed movement, the planer's feed movement is the intermittent movement of the table (or planer).

Planers can be planed for horizontal planes, vertical planes, slopes, curved surfaces, step surfaces, dovetail-shaped workpieces, T-slots, V-grooves, as well as planing holes, gears, and racks. If the planer is properly modified, the planer's scope of application can be expanded.

With a planer knife, the ram is used as a planer for rectilinear motion. Because the turret's front tool holder is shaped like a bull's head, it is also known as a planer. The planer is mainly used for planing, forming surfaces and grooves on small and medium-sized workpieces in small batch production. The main movements of small and medium sized planers mostly use the crank-rocker mechanism (see the crank-slider mechanism) for transmission, so the ram's moving speed is not uniform. The large bull planers mostly use hydraulic transmission, and the ram is basically a uniform motion. The return stroke speed of the ram is greater than the working stroke speed. Due to the use of single-edged planers and no cutting during the ram return, the productivity of the planer is low. The main parameter of the machine is the maximum planing length. The planer is moved horizontally and linearly by the ram and the planer. The tool holder can be rotated at an angle in the vertical plane, and can be manually fed. The worktable carries the workpiece for intermittent horizontal or vertical feed motion. It is commonly used for machining planes. , grooves, dovetails, etc. Contouring planer is to add a profiling mechanism on the ordinary planer for processing forming surfaces, such as turbine blades. The rams and carriages of the mobile planer can also be moved on the bed (horizontal) or upright (vertical), suitable for planing the local plane of large workpieces.
