Drum grinding machines are used for auxiliary and basic operations related to grinding surfaces. The basis of the work is a drum on which the grinding skin is fixed. It spins, and the system brings the workpiece by turning it.
What are good drum angle grinders
The table is used as a support for the workpiece and hands. The machine allows you to remove a layer with a thickness of 0.1 mm. If necessary, you can carry out a larger removal, pressing harder. In one pass, this way you can remove the layer up to 1 mm. These machines have their own feed rate. This is a pretty important factor when choosing a device.
If we compare these devices with other machines, they are safe, because all movements are controlled, the removal is relatively small, there is a machine for harvesting, and there are no sharp rotating elements. For example, you can consider the technical specifications and the device of the Corvette-57 machine. It will be discussed in the article.
Specifications and feedback on them
This drum-grinding equipment is a machine for polishing and grinding flat surfaces. Processing can be made of plastic or wood. “Corvette-57” works due to the powerful engine, which provides uniform processing of the plane.
In addition to the equipment, you can connect a vacuum cleaner, which will save time on cleaning and make work tidy. Due to two plates, the desktop is lengthened. This, as the owners emphasize, allows you to process long workpieces. The power of this device is 1100 watts. The supply of the workpiece is smooth, and the speed is up to 3 m per minute.
additional characteristics
The maximum grinding width, according to the masters, is quite impressive and is 405 mm. The diameter of the suction port is 100 mm. This unit weighs 91 kg. The design does not have a brush shaft. The grinding cylinder has the following dimensions: 132 x 410 mm. Corvette 57 has the following dimensions: 920 x 660 x 610 mm. The maximum thickness of the workpiece is 130 mm. The drum rotates at a speed of 1,440 rpm.
Main advantages
Thanks to the fine dust extraction pipe, it is possible to maintain cleanliness in the workplace. This drum grinding machine can be used in conjunction with a vacuum cleaner. Consumers who have already managed to test the quality of the unit, note that the Corvette-57 provides high accuracy. It is guaranteed by a dimensional scale, due to which you can lower the drum to the desired height.
The wheels have a large diameter, which simplifies transportation. This is important, according to buyers, because the design is quite massive. This device has additional benefits. Among them are the following:
- the presence of two extension cords for the desktop;
- ease of making adjustments;
- automatic feed speed;
- balance of the grinding drum.
The Corvette-57 machine, as the masters emphasize, is very convenient due to the fact that it can be used to process overall workpieces. The stability of the operations is increased due to the rigidity of the structure. You can smoothly adjust the automatic feed speed, which is very important for beginners.
The grinding drum is equipped with dustproof rolling bearings, which extend the life of the device. Grinding machine "Corvette-57" has a fairly compact size, which allows you to install it in cramped conditions, for example, in a garage.
Device model
Before you make a choice in the direction of a particular model of circular grinding machine, you should familiarize yourself with the device of such equipment. The basis is the desktop, which is in a horizontal position. It is used for fastening the workpiece in the cartridge. The spindle head is also vertically located, where the abrasive tool is installed.
Enkor Corvette 57 can be serviced independently. An alternative solution is tuning through program control. Before you work, you will need to set the position of the grinding wheel relative to the part. Rotational-translational movements of the product will be directed along the horizontal axis.
The top layer will be removed from the surface of the workpiece with subsequent displacement of the tool to the working depth. Using the Corvette-57 drum grinding machine, you can perform rough and finish grinding operations. For this, only the rotation speed of the tool should be determined.
Possible malfunctions and solutions
Often during the operation of the machine you can notice malfunctions. They affect the quality of product processing, and their untimely elimination reduces the service life of the device. If, for example, the sanding belt sags, the cause may be incorrect installation. During grinding, the workpiece may burn. In this case, it can be assumed that the edges of the tape are overlapped. Sometimes the cause is adherent resin. The workpiece can also burn with an impressive grinding depth or a slow feed rate. A solution to the problem may be the installation of a tape with a larger grain size for roughing.
If the belt slips at the Ankor Corvette-57 grinding machine, this may indicate a weak tension. You can reduce the grinding depth or adjust the tension by lowering the feed rate.
On the tape, according to the masters, the workpiece can also slip. The reason for this is the high feed rate, worn tape or its contamination. The tape needs to be cleaned or replaced, reducing the table feed speed. When working on the Enkor Corvette-57 drum grinding machine, craftsmen sometimes encounter uneven undulations on the surface of the workpiece after processing. This can be caused by uneven table speeds. To solve the problem, it is necessary to strengthen the shaft coupling, if the fault is not properly qualified, you should contact the service center.
Tape Installation Guidelines
In order to avoid injuries, the machine must be disconnected from power before replacing abrasive belts or servicing. The ribbons look like stripes cut according to the pattern. They do not require special measurements or trimming before installation. The strips have narrowing at the ends so that they can be wrapped around the drum, achieving uniform grinding.
You can cut your own stripes yourself. To do this, use the grinding strip as a template. After you have verified that the machine is disconnected from the power source, open the dust collector cover. The tape is inserted into the slot 25 mm to the left of the drum. It is fixed, bringing the clamp into position.
When the tape is fixed, stand in front of the machine and wrap it around the drum. To do this, the drum is rotated away from itself, while maintaining the tension of the tape. It is important to ensure that no abrasive strip is applied during wrapping. A small gap between the turns is allowed, it will not affect the quality of grinding. Overlaying can cause carbonization of the workpiece or uneven surface treatment.
When the drum is wrapped with the desired tension, insert the tapered end into the slot. After this, the clamp must be locked with your right hand. The mechanism will tension the belt and maintain tension during operation. After the manipulations, close the dust collector cover. The device is ready for use again.
Conclusion
The grinding machine has a drum design and is used for preliminary grinding to the desired thickness and final processing of products to the specified dimensions. Such equipment is used for processing primed and varnished surfaces. The machine has a powerful asynchronous motor that drives the drum. For automatic feeding, the design is equipped with a collector motor.
