Overview of the characteristics and performance of the three planers

Planer, it is a kind of machine tool, and it is a linear motion, which can be processed, but because of its low productivity, it is only suitable for single-piece or small-batch production and processing. In mass production, it is generally used The milling machine replaces the planer. Planers can be mainly divided into bull's head planers, planers, single-arm planers and specialized planers. 1. Single-arm planer The single-arm planer has a single column and a cantilever, and the worktable reciprocates longitudinally along the bed guide rail. It is mostly used for processing workpieces with large widths that do not need to be processed over the entire width. 2. The bull head planer is named after the ram and the tool holder are shaped like bull heads. The planer is mounted on the ram tool holder for longitudinal reciprocating motion. It is mostly used to cut various planes and grooves. It is suitable for planing lengths of not more than 1000 mm. Of small and medium-sized parts. The characteristic of the bullhead planer is that it is easy to adjust, but because it is a single-edge cutting, and the cutting speed is low, it does not work during the return stroke, so the production efficiency is low, and it is suitable for single-piece small batch production. The planing accuracy is generally IT9-IT7, and the surface roughness Ra is 6.3-3.2um. The main parameter of the bull's head planer is the planing length. 3. Gantry planer is named after a gantry frame structure composed of a top beam and a column. The worktable carries the workpiece through the gantry frame for linear reciprocating motion, and is mostly used for processing large planes (especially long and narrow planes). ), also used to process grooves or to process the planes of several small and medium-sized parts at the same time. Large gantry planers are often attached with components such as milling heads and grinding heads, so that the workpiece can be planed, milled, and plane-grinded after one installation. The planer mainly processes large workpieces or multiple workpieces at the same time. Compared with the bull's head planer, from the structural point of view, its shape is large, the structure is complex, and the rigidity is good. From the machine tool movement, the main movement of the planer is the linear reciprocating movement of the worktable, and the feed movement is the horizontal or Vertical intermittent movement, which is just the opposite of the movement of the bull's head planer. The gantry planer is driven by a DC motor and can be steplessly adjusted to ensure smooth movement. Longmen planers are mainly used to process large planes, especially long and narrow planes. Generally, the width of the work piece that can be planed is 1 meter and the length is more than 3 meters.
