Since ancient times, people have had a question about the processing of metal and wood products. Often, it was necessary to make a hole in the workpiece for the product - through or deaf, depending on the conditions for further use. In ancient times, holes were made in wood products using pointed metal objects. Metal was learned to process much later. Initially, metal blanks were processed using hand-held gimlets. After that, metalworking machines were invented with their subsequent automation. In the article we will talk about drilling machines "Corvette", which have gained popularity among craftsmen.
Drilling machines have greatly simplified metalworking, allowing a person to perform many operations, such as:
- drilling;
- countersinking;
- reaming.
On the basis of drilling machines, milling machines were subsequently made. In drilling machines, a special tool is used - drills, countersinks and countersinks. These tools made it possible toholes in stronger metals.
Drilling machine "Corvette"
Drilling machines belong to the category of wood and metal cutting machines, with their help, blind or through holes are obtained in the workpiece being processed. Also, with the help of Korvette drilling machines, it is possible to perform such operations as reaming and reaming, countersinking (chamfering), threading. The machine allows you to perform these operations without much effort.
The main elements of the drilling machine "Corvette":
- The machine bed is the main element that carries all other parts and fixtures.
- Gearbox, as well as an electric motor, which is often asynchronous (sometimes collector type). They are connected to the rotation transmission shaft using belts or gears.
- The rotational movement 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.
- Working coordinate table, which is used to clamp and sometimes move the workpiece during processing.
Depending on the processing conditions, machines are divided into radial and standard. Standard drilling machines "Corvette" process only workpieces with the possibility of moving, the drill is rigidly fixed in the spindle. Radial machines have the ability to move the drill with a rigid mountblanks.
"Corvette-44": machine description
The Korvette-44 drilling machine is practically the most expensive of its younger brothers. The machine is the most reliable and easy to operate, as well as more accurate and is perfect for small-scale production. It is equipped with a 650W asynchronous motor with a rotation speed of 120 to 3000 rpm.
On the desktop, the location of the vise, which are included in the factory package, is possible. The drilling machine "Corvette" is equipped with an additional means of protection - a transparent screen that protects a person from getting hot chips into the eyes and parts of the body. There is also an emergency shutdown button for the machine.
"Corvette-44": characteristics
The Korvette drilling machine has the following characteristics:
- 16 spindle speed settings.
- 650W motor from 120 to 3000 rpm
- Possibility of using a drill when processing a product up to 16 mm.
- The spindle is lowered during processing - up to 80 mm, its removal from the rack - up to 175 mm.
- Working coordinate table has dimensions of 290290 mm.
- The weight of the machine is 67 kg.
- Machine dimensions - 815059 cm.
The only drawback of this model is the lack of coolant supply, which is used in machines of this price category. ATIn some cases, coolant can be added manually.
"Corvette-45": design features
Drilling machine "Corvette-45" has in its design similar units "Corvette-41", but some changes have been made. The machine uses a 350 W asynchronous motor with the expectation of continuous loads when processing the product. On this drilling machine "Encor Corvette" additional means of protection are used, such as the presence of an emergency shutdown button, a transparent protective screen.
As for the electrical part, the machine has zero voltage protection 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. It contains a system for transmitting movement from the motor to the spindle. On the coordinate desktop, there is the possibility of arranging a vise to secure the workpiece during processing.
"Corvette-45": characteristics
Drilling machine "Corvette-45" has the following characteristics:
- 350W asynchronous motor designed for continuous processing load.
- Possibility of using drills up to 13 mm in diameter.
- The lowering of the spindle during machining is 50mm, and the distance from the column to the spindle is 150mm.
- The spindle taper is B16
- Desktop dimensions - 160160 mm.
These are the main characteristics, more details can be found in the instructions forspecific machine.
