1. Construction and industry
It is widely used in the reinforcement of building beams, slabs, columns, walls, etc., decoration, wall installation, brackets, railings, billboards, air conditioner outdoor units, guide rails, satellite receiver elevators, steel structure workshops, etc.
2. Medical application
(1) Dentistry:
At the beginning of the 20th century, there were wall-mounted three-bend dental drills with a speed of 4000 r/min and some even up to 10000 r/min. The three-boom rigs that we still use in the widely used sheave drive are derived. Things.
(2) Otology:
Julius Lempert, the father of modern otology, first used ear drills in New York in 1938 to treat chronic ear disease and reduce the incidence of facial nerve damage. But the electric drill at the time was difficult to control and the noise was very loud. Modern electric drills and pneumatic drills greatly increase the speed and enhance the cutting capacity. The use of fast cutting drills, diamond drill bits and flush-pumping systems enables otologists to quickly complete accurate surgical dissections and greatly reduce the time required for surgery.
3. Marine soft rod drill
A new type of marine drilling equipment is mainly used for core sampling of seafloor sediments and exploration of marine geology and minerals. First, it was successfully developed by the French Petroleum Research Institute (IFP). It was originally used for drilling 300 meters and 500 meters of boreholes on land. Later, it cooperated with the Soviet Union to drill oil wells up to 3,000 meters. In 1965, the first successful test at sea, drilling water depth of 2,500 meters. The ECSM marine soft-hearted electric drill is to install the flexible rod, the electric drill, the core tube, the drill bit and the submersible pump on the same frame, and put it down to the sea bottom with a wire rope, and power supply from the ship surface through the cable and realize remote drilling. It can be drilled to a depth of 100 meters at a depth of 500 meters and a 3.5 inch core can be taken out. The machine weighs about 10 tons.
