Opportunities
In this model of the Makita 9555HN angle grinder, it is possible to lock the spindle, as well as the ability to lock the power button.
Thanks to these options, reliable use and additional ease of use of this tool are ensured.
Device
Makita 9555HN grinder has a cylindrical body, the handle is located near the attachment point of the nozzles. The main structural elements are:
- bevel gear;
- universal commutator motor;
- starting switch or traction converter;
- electric motor.
Principle of operation
The principle of operation of this device is based on the conversion of an angular gear and an electric motor into mechanical energy.
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 a specific power to ensure the optimal number of revolutions. The model Makita 9555HN permissible linear rotation speed on the edge of the disk is not more than 80 m / s. Exceeding this value is unsafe, while low values can reduce the performance of the machine. For this reason, in this model with nozzles of small diameter, their rotation speed is significantly higher than that of devices equipped with large disks.
Usage and Features
Functional angle grinders differ from similar devices of other types because they can be used, except for grinding, for cutting various materials, except for wood. Angle grinders are universal, which is their advantage. A wide area of use of this tool is provided by a set of working nozzles. Although the 9555HN is considered a one-handed machine, you still need to hold it with 2 hands, because this device is very dangerous. This model lacks the main handle, its part is played by the part of the body, which is covered with elastomer.
Angle grinders are equipped with dustproof motors, walls of the labyrinth seal, which separate the bearings from the air tubules, and sealed control buttons.
The general measure used to reduce the noise of angle grinders is the use of gears with helical gears.
To protect against overheating, the gearbox is protected by a metal casing. To facilitate the replacement of nozzles, the tool provides for locking the spindle, the button of which is located on the gear case. Maintenance of the machine is greatly facilitated by the presence of quickly clamping units. Thanks to this, a quick change of nozzles and removal of the protective cover without the use of tools is possible.
Rules for choosing grinding machines
Before you purchase an angle grinder, you need to determine why you plan to buy a tool. The most convenient and productive in work are professional models that provide the best quality work and are equipped with devices that increase ease of use. In addition, such grinding devices are highly reliable, because they are designed 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 be unrealized with a single use.
Household appliances are limited in duration of continuous use, they are not so convenient and productive. But this compensates for a significantly lower price, and the inconvenience is not particularly noticeable with rare use. In addition, non-professional devices, as a rule, have compact dimensions, which makes them easy to carry, as well as less weight, which facilitates the use.
The size of the nozzles for Makita 9555 HN household angle grinders 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 coatings from various elements, including when performing bodywork.
Makita 9555HN: Description of Useful Features
Some models of angle grinders are equipped with features that greatly simplify work or increase productivity, safety or convenience. To choose the right device, it is necessary to present their essence.
- The ability to adjust the speed of rotation of the disk: due to this, the device can be adapted to perform various works and install nozzles of different diameters.
- Electronic stabilization: able to maintain a constant number of revolutions, regardless of the loads experienced by the angle grinder.
- Automatic disk balancing: significantly reduces vibration during operation and reduces disk wear. Such a system is a special coupling equipped with balls immersed in oil and grouping at the point of location of the center of gravity.
- Disc brake: significantly reduces the running time to three seconds.
- Accessibility of brushes: thanks to this, you can inspect the brushes for wear and, if necessary, change without visiting a service center. To do this, an opening is provided on the housing, which is closed by an easily removable plug.
- Removable network cable: very convenient during replacement in case of damage and during transportation of the device.
- Suitcase: in such a case it is very convenient to store and carry the device.
