Nine applications and three characteristics of power tools
There are many varieties of power tools, and the world's power tools have grown to nearly 500 varieties.
Three major characteristics:
1. Lightweight structure, easy to carry and use.
2. It can increase labor productivity several times to dozens of times than manual tools;
3. Higher efficiency than pneumatic tools, low cost, low vibration and easy to control.
Nine applications:
1) In the machinery industry: drilling, tapping, sawing, rust removal, polishing, polishing, expansion and screwing, fastening of bolts and nuts, etc.
2) Farmland transformation, water conservancy construction, tunnel construction, mining: rock drilling, concrete compaction.
3) In the construction of the railway; the road residue is compact.
4) Agriculture and animal husbandry: spraying, shearing.
5) In tea picking and forestry: logging, planting, and branching.
6) Wood processing: sawing, planing, opening, sanding.
7) Medical aspects; saw bone, bone drill, and plaster removal.
8) Arts and crafts: carving, carpet cutting.
9) Special use: shearing steel plate, punching and cutting hole, angle drilling to drill the workpiece in a small place, magnetic drilling can be absorbed on the processed steel parts, self-climbing sawing machine can automatically cut large diameter steel pipe, set The torque wrench can control the bolt to reach a constant tension, and the rivet gun can rive the workpiece on one side.
