Planers are usually classified according to their main structures and accordingly they can be of the following types: i. One side, ii. Double housing, iii. Pit edge (plate), iv. Profile type. The open side planer is made with only one supporting column. Its main advantage is that work may be extended out over the bed. It is less rigid. Three [...]
The block diagram showing the principal parts of the double housing planer is shown in Fig. 15.1 and the various parts are described below: Part # 1. Bed: Planer bed is a very strong and robust structure, made out of cast iron and strengthened with cross-ribs. On very long planers the bed is sometimes made from two or more castings [...]
The following points highlight the top four operations of planing in the industries. The operations are: 1. Planing Vertical or Angular Surfaces 2. Gang Tooling 3. Double Cutting Tool Boxes 4. Hot Planning. Operation # 1. Planing Vertical or Angular Surfaces: In such cases, the side-head may be used to advantage. If the cross- rail tool head is to be [...]
Planing tools have a relatively large cross-section because they are designed for maximum rigidity. The shank of the tool is made of high strength heat treated alloy steel and inserts are brazed or held mechanically on the shank. By using carbide tools in place of HSS, the planing time can be reduced by about 50%. The number and variety of [...]
