Drum grinders are used for auxiliary and basic operations related to surface grinding. The work is based on a drum on which a sanding skin is fixed. It spins, and the system brings the workpiece by turning it.

What makes drum angle grinders good

The table serves 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, more can be removed by pressing harder. In one pass, a layer of up to 1 mm can be removed in this way. These machines have their own feed rate. This is quite an important factor when choosing a device.

If we compare such devices with other machines, then they are safe, because all movements are controlled, the removal is relatively small, there is a device for the workpiece, but there are no sharp rotating elements. For example, we can consider the technical characteristics and device of the Corvette-57 machine. It will be discussed in the article.

Specifications and reviews about them

This drum grinding equipment is a machine for polishing and grinding flat planes. You can process blanks made of plastic or wood. The Corvette-57 operates due to a powerful engine that provides uniform processing of the plane.

In addition, a vacuum cleaner can be connected to the equipment, which will save time on cleaning and make the work neat. Due to the two plates, the desktop is extended. This, as the owners emphasize, makes it possible to process long workpieces. The power of this device is 1100 watts. The workpiece is fed smoothly, and the speed is up to 3 m per minute.

Additional Features

The maximum grinding width, according to the masters, is quite impressive and is 405 mm. The diameter of the suction hole is 100 mm. This unit weighs 91 kg. There is no brush shaft in the design. 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 workpiece thickness is 130 mm. The drum rotates at a frequency of 1440 rpm.

Key Benefits

Thanks to the fine dust tube, you can keep your workplace clean. This drum sander can be used in conjunction with a vacuum cleaner. Consumers who have already experienced the quality of the unit note that the Corvette-57 provides high accuracy. It is guaranteed by a dimensional scale, due to whichyou can lower the drum to the desired height.

The wheels have a large diameter, which makes it easy to transport. This is important, according to buyers, because the design is quite massive. This device has additional benefits. Among them it is worth highlighting:

• the presence of two extension cords for the desktop;
• easy to make adjustments;
• auto feed speed;
• balance of the sanding drum.

Machine "Corvette-57", as the craftsmen emphasize, is very convenient due to the fact that it can be used to process dimensional workpieces. The stability of the operations performed is increased due to the rigidity of the structure. You can smoothly adjust the automatic feed speed, which is very important for beginners.

The sanding drum is equipped with dust-proof rolling bearings, which extend the life of the device. The Korvette-57 grinding machine has a fairly compact size, which allows it to be installed in cramped conditions, for example, in a garage.

Model device

Before you make a choice in the direction of a particular model of a circular grinding machine, you should familiarize yourself with the device of such equipment. It is based on a desktop, which is in a horizontal position. It is used for fastening the workpiece in the chuck. The headstock is also vertically located, where the abrasive tool is installed.

"Encor Corvette-57" can be serviced independently. As an alternativeThe solution favors setting through program control. Before work, you will need to set the position of the grinding wheel relative to the part. The 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, followed by the tool shift to the processing depth. With the help of the Korvette-57 drum grinding machine, it is possible to perform rough and fine grinding operations. To do this, only the speed of rotation of the tool should be determined.

Possible malfunctions and solutions

It is not uncommon to notice malfunctions during machine operation. They affect the quality of processing products, and their untimely elimination reduces the service life of the device. If, for example, the sanding belt sags, this may be due to 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 adhering resin. The workpiece can burn even with an impressive grinding depth or a slow feed rate. The solution to the problem may be to install a belt with a coarser grit for roughing.

If the belt slips on the Enkor Corvette-57 grinder, this may indicate its weak tension. You can reduce the grinding depth or adjust the tension by reducing the feed rate.

On the tape, according to the masters, the workpiece can also slip. The reason for this isHigh feed speed, worn or dirty ribbon. The belt must be cleaned or replaced by reducing the table feed speed. When working on the Enkor Corvette-57 drum grinding machine, craftsmen sometimes encounter uneven waviness on the surface of the workpiece after processing. This may be caused by uneven table speed. To solve the problem, it is necessary to strengthen the shaft coupling, if you do not have enough qualifications to fix the problem yourself, you should contact the service center.

Ribbon Installation Recommendations

To prevent injury, unplug machine before changing abrasive belts or servicing. Tapes look like strips cut according to a pattern. They do not require special measurements or trimming before installation. The strips are tapered at the ends so that they can be wrapped around the drum for an even finish.

You can cut your own strips yourself. To do this, use the sanding strip as a template. After you have made sure that the machine is disconnected from the power source, you should open the dust container cover. The tape is inserted into the slot to the left of the drum by 25 mm. It is fixed by 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 make sure that the abrasive strip does not overlap during wrapping. A small gap between the turns is allowed,it will not affect the quality of grinding. Overlapping may cause charring of the workpiece or uneven surface finish.

When the drum is wrapped with the right tension, insert the tapered end into the slot. After that, you need to fix the clamp with your right hand. The mechanism will tension the belt and keep the tension during operation. After the manipulations, you need to close the lid of the dust collector. The device is ready for use again.

Conclusion

The grinding machine has a drum design and is used for pre-grinding to the desired thickness and final processing of products according to 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 commutator motor.
