Device

The Makita 9555HN grinder has a cylindrical body, the handle is located near the fixation point of the nozzles. The main elements of the design are:

• Angular gearing;
• Universal collector motor ;
• Starting switch or traction converter;
• Electric motor.

Principle of operation

The principle of functioning of this device is based on the transformation of the angular gear and the motor of electrical energy into a mechanical one.

One of the main characteristics of such devices is the diameter of the working nozzle, on the basis of which the angle grinders are equipped with engines of specific power to ensure the optimum number of revolutions. For the Makita 9555HN, the permissible linear rotation speed at the edge of the disc is not more than 80 m / s. Exceeding this value is unsafe, while low values can reduce the productivity of the machine. It is for this reason that in this model with nozzles of small diameter, the speed of their rotation is substantially greater than for instruments equipped with large disks.

Uses and features

Angular grinders for functional purposes differ from similar devices of other types, because they can be used, except for grinding, for cutting different materials, except for wood. Angle grinders are universal, and this is their advantage. A wide scope of use of this tool is provided by a set of working attachments. Although the 9555HN is considered a one-handed machine, it still needs to be held with two hands, because this device is very dangerous. This model lacks the main hilt, its role is performed by the hull part, which is covered with an elastomer.

Angle grinders are equipped with dustproof motors, walls of a labyrinth seal, which separate the bearings from the air ducts, and pressurized control knobs.

The general measure used to reduce the noise of angle grinders is the use of gears having helical gears.

To protect against overheating, the reducer is protected by a metal casing. To facilitate the replacement of attachments in the tool, a spindle lock is provided, the button of which is located on the gear housing. Maintenance of the machine is greatly facilitated by the presence of fast clamping units. This makes it possible to quickly replace the nozzles and remove the protective cover without using tools.

Rules for selecting grinders

Before you buy an angle grinder, you need to determine what you plan to buy the tool for. The most convenient and productive in work are professional models, providing the best quality of work and equipped with tools that increase the usability. In addition, such grinding devices are highly reliable, because they are calculated for regular use for several hours a day. They are great for professional use, for example, in services and workshops. For household use, it is not advisable to buy such devices, because their purchase will require significant costs, and many of the opportunities available in them will not be realized for one-time use.

Household appliances are limited in duration of continuous use, they are not so convenient and productive. But this compensates for a much lower price, and the inconvenience is not particularly noticeable with rare use. In addition, non-professional devices tend to be compact in size, which makes them easy to carry, and also less weight, which makes application easier.

The size of the nozzles for household corner grinders Makita 9555 HN varies from 115 to 125 millimeters. They are not intended for cutting materials whose thickness exceeds 50 millimeters, but such devices are quite suitable for domestic needs, polishing, grinding, removing corrosion and paint coatings from different elements, including when doing bodywork.

Makita 9555HN: description of useful functions

Some models of angle grinders are equipped with features that greatly simplify operation or increase productivity, safety or convenience. To properly choose a device, you need to represent their essence.

• Ability to adjust the rotational speed of the disk: due to this, the device can be adapted to perform various jobs and install nozzles of different diameters.
• Electronic stabilization: can maintain a constant number of revolutions, regardless of the loads experienced by the angle grinder.
• Automatic disc balancing: significantly suppresses vibration during operation and reduces disc wear. Such a system is a special clutch equipped with balls immersed in oil and grouping at the point of the center of gravity.
• Drive brake: greatly reduces the run-out time to three seconds.
• Availability of brushes: due to this you can inspect the brushes for wear and, if necessary, change, without visiting the service center. For this, an opening is provided on the body, which is closed by an easily removable plug.
• Removable network cable: very convenient during replacement with damages and during transport of the device.
• Case: in this case it is very convenient to store and carry the device.
