How to choose the right cutter

Today it is quite difficult to name the exact number of all those works where a chaser may be required. This technique has been developed for the opening of the roadway, the restoration of cracks and cutting coatings for communication channels. Nowadays, with its help, landscaping, car parks and even runways for airplanes are being equipped. The device easily makes the seams of a given depth in asphalt and concrete coatings and is the only technical device that is successfully used to process any non-metallic surfaces. However, the main scope of the joint cutter remains the repair and construction works and road maintenance.

Tool design

Usually, all models are a standard design that consists of a sturdy frame, a powerful engine, a round diamond cutter and a control panel. The mechanism has a special coating that protects the operator of the device from falling into it of concrete chips. In addition, the tool provides for adjustment of the depth of the seam.

The main part of the cutter is diamond discheadwhich is available in several types. It is chosen for a specific type of upcoming work. For example, if you plan to cut asphalt, then a disk with rare teeth is taken, and for cutting concrete, a specimen with closely spaced and smaller teeth is selected.

The saw cutter has two modes of operation: dry and wet. In the second variant, its diamond cutter is moistened with water, regularly coming from a special container, fixed under the device panel.

Cutting with a joint cutter replaces several tools at once, which include a jackhammer and scrap. When working with them, it will take a lot of physical effort and a lot of timewhereas with a chaser, the amount of work will be completed quickly and without much stress, even if there are reinforcements in the hardened concrete.

Types of joint cutters and their comparative characteristics

Manual seam cutter is a very useful tool with many advantages over other units. The device is of three types.

1. Diesel. It is used on road and large industrial facilities. These are the most powerful of all devices, they easily cope with high industrial loads. Can cut to a depth of 10,000mm.
2. Electric. Used for work, mainly in closed areas. The main advantages are the absence of exhaust gases and a low level of noise. The main disadvantage is a small area of ​​use, completely dependent on the length of the electrical cable. Can cut to a depth of 500 mm.
3. Gasoline. These are the most popular and popular models. The main advantages are autonomy and high power. The main disadvantage - exhaust gases, limiting the scope of their application.

The most widespread of the carvers is gasoline, as it has a number of undeniable advantages.. Gasoline shovnerezchik very maneuverable and can be used where there is no electricity. It has a small size compared to diesel options. For example, its most powerful model weighs no more than 600 kilograms. At the same time, despite the modest size, it has great power and can easily cope with very strong types of asphalt and reinforced concrete. In addition, the gasoline unit is a cost-effective option, as it costs much less than electric.

Rules of the tool

When planning the construction and repair works, in each case a certain chaser is selected. In the case when the depth of the seam is not so large, you can use a seam cutter with a manual drive. For deeper cutting in asphalt concrete pavement, models are used that have hydraulic drive. This unit significantly increases labor productivity and makes the work of the operator much easier.

While using the chaser, it is necessary to carefully monitor its disc. During prolonged work on it must constantly water flowserving as a cooling. This is especially important for concrete.If this condition is not met, then the service life of the diamond disc will be several times lower than the calculated one. In preparation for the beginning of the working cycle, it is necessary to check the fixation of the nozzle and the presence of possible backlash.

Starting the device must be carried out before the contact of the diamond disk with the surface to be treated.

If it is planned to use a fuel unit at the facility, then it should be remembered that during its operation significant exhaust emission. Therefore, this type of joint cutter is recommended for asphalt in open and well ventilated areas.

Characteristics for selection

The main indicator of any chisel is the cutting depth, which determines the technical characteristics of this equipment.. As a rule, the depth of the joint depends on the disc on the joint cutter, as well as on the power of the unit, which can be in the range from 1.2 kW to 3 kW and more. The power of the apparatus is selected depending on the upcoming work front.

For example, for domestic use, from 1.2 to 1.5 kW is sufficient, and for professional use - ranging from 2 kW and above.

Many well-known manufacturers equip their models with a set of special featureswhich successfully complement their basic characteristics. These include:

• protection against unforeseen overloads,
• special system, leveling the destructive effects of vibration,
• smooth start-up equipment and a range of other technical solutions that manufacturers are constantly trying to improve.
