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 applications
(1) Dentistry:
In the early 20th century, there was a wall-mounted three-bend arm dental drill with a speed of 4000r/min and some even up to 10000r/min. Now we are still using the widely used three-boom rig for the sheave drive. derivative.
(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 bits, diamond 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 Institute (IFP). It was originally used for drilling 300 meters and 500 meters of land on the land. Later, it worked 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. ECSM marine soft-hearted electric drills are equipped with flexible rods, electric drills, core tubes, drill bits and submersible pumps on the same frame. They are laid down to the seabed with wire ropes, powered by the ship's surface and remotely drilled. 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.
