Since ancient times, people have a question about the processing of metal and wood products. Often in the workpiece for the product it was required to make a hole - through or blind, depending on the conditions of further use. In ancient times, in wood products, holes were made using metal pointed objects. They learned to process metal much later. Initially, metal billets were processed using hand drills. After that, metalworking machines were invented with their subsequent automation. In the article we will tell you about Corvette drilling machines, which have gained popularity among craftsmen.
Drilling machines have greatly simplified metalworking, allowing a person to perform many operations, such as:
- drilling;
- countersinking;
- countersinking.
Milling machines were subsequently manufactured on the basis of drilling machines. In drilling machines, special tools are used - drills, countersinks and countersinks. With these tools, it has become possible to make holes in stronger metals.
Drilling machine "Corvette"
Drilling machines belong to the category of wood and metal cutting, with their help in the workpiece they receive blind or through holes. Also, with the help of Corvette drilling machines it is possible to carry out operations such as deployment and countersinking, countersinking (chamfering), threading. The machine allows these operations to be performed without much effort.
The main elements of the Corvette drilling machine:
- The bed of the machine is the main element that carries all the other parts and accessories.
- The gearbox, as well as the electric motor, which is often asynchronous (sometimes collector type). They are connected to the shaft of the transmission of rotation using belts or gears.
- The movement of the rotation of the engine is transmitted to the drill using a special device, it is called a spindle.
- Special drill feed mechanism in vertical and horizontal planes.
- The working coordinate table, with the help of which the workpiece is fixed and sometimes the workpiece is moved during processing.
Depending on the processing conditions, the machines are divided into radial and standard. Corvette standard drilling machines process only the workpiece if it is possible to move, the drill is rigidly fixed in the spindle. Radial machines have the ability to move the drill with a rigid fastening of the workpiece.
"Corvette-44": description of the machine
Drilling machine "Corvette-44" is almost the most expensive of a number of his younger brothers. The machine is the most reliable and easiest to operate, as well as more accurate and perfect for small-scale production. It is equipped with a 650 W induction motor having a rotation speed of 120 to 3000 rpm.
On the desktop, it is possible to arrange a vise that is included in the factory equipment. The Corvette drilling machine is equipped with an additional protective tool - a transparent screen that protects a person from getting hot shavings into the eyes and body parts. There is also an emergency button to turn off the machine.
Corvette 44: specifications
Corvette Drilling Machine has the following characteristics:
- 16 modes of spindle speed.
- The engine is 650 watts at a speed of rotation from 120 to 3000 rpm.
- The possibility of using a drill when processing products up to 16 mm.
- The spindle is lowered during processing - up to 80 mm, its removal from the rack - up to 175 mm.
- The working coordinate table has dimensions of 290 * 290 mm.
- The weight of the machine is 67 kg.
- Dimensions of the machine - 81 * 50 * 59 cm.
Allocate the only drawback of this model is the lack of coolant supply, which is used in machines of this price category. In some cases, coolant can be supplied manually.
Corvette-45: design features
Corvette-45 drilling machine has similar Corvette-41 units, but some changes have been made. The machine uses a 350 W induction motor with the expectation of continuous loads during product processing. This Enkor Corvette drilling machine uses additional security features, such as an emergency shutdown button and a transparent protective screen.
On the electrical side, the machine has protection against zero voltage in the form of a magnetic starter, as well as a limit switch that turns off the engine when the top cover of the machine is opened. On it is a system for transmitting movement from the engine to the spindle. On the coordinate desktop there is the possibility of arranging a vise to secure the workpiece during processing.
Corvette-45: characteristic
The Corvette-45 drilling machine has the following characteristics:
- 350 W induction motor designed for continuous processing.
- Possibility of using drill bits up to 13 mm in diameter.
- Lowering the spindle during processing is 50 mm, and the distance from the stand to the spindle is 150 mm.
- Spindle cone has class B16
- Dimensions of the desktop - 160 * 160 mm.
These are the main characteristics, more details about the details can be found in the instructions for a particular machine.
