Any self-respecting master needs high-quality equipment with which he can quickly and easily accomplish the tasks assigned to him. One of the main tools that should be in the arsenal of every woodworker is a hand planer.
When working with an electrical planer, the entire load rests on the engine, not the hands of a person, which greatly simplifies and speeds up the process.
Many people face some difficulties when purchasing this equipment. This is mainly due to the fact that in the modern market of electrical equipment planers are represented by different models of both domestic and foreign manufacturers.
The principle of manual electroplane
For the correct selection and operation of any power tool, you need at least a little understanding of its design and principle of operation. In contrast to the mechanical planer, electric models are much more convenient and faster to operate, since almost the entire load falls not on the master’s hands, but on the electric motor. The basic list of operations that can be performed by a planer consists of planing, machining to size, beveling, trimming, and quarter sampling. And if additional devices are used together with the plane, this list can be significantly expanded.
Figure 1. Diagram of the electroplaning device.
Despite the large variety of electric planes, their design and principle of operation are almost the same (Fig. 1). The main element is the electric motor that controls the operation of the drum on which the cutting knives are placed. In order for the wood surface processed by the instrument to be smooth, the engine must have a certain power (0.6 kW or more), and the drum must have a rotation speed of more than 10,000 rpm.
Using the drive belt rotational motion from the engine is transmitted to the drum. Due to the fact that the electric motor is equipped with the technology of “soft start” and allows you to automatically maintain the speed of rotation of the drum at the required level, the possibility of motor overload during its operation is almost completely excluded.
The sole of a plane is made of high-quality aluminum. The back of the sole is fixed, and the front - movable, which allows it to easily move on the still untreated surface and adjust the height, setting the desired depth of wood processing.Back to table of contents
Professional or household option
Manual planers, like any other electric tool, are divided into household and professional. Household models are cheaper, but professional - better and more reliable.
Household electroplaning scheme.
Household planers are designed for periodic use in the home, they can perform simple work. When using such equipment it is necessary to observe the recommended mode of operation: 15-25 minutes to work, then 10-20 minutes to rest. If the tool to work without stopping for more than half an hour, then this can lead to a significant reduction in its operating life or failure.
Professional manual planers - equipment with a large resource, designed for long-term work. Visually determine that it is a professional model in front of you is quite simple, because there are not so many brands that produce such a tool. Makita, Bosch, Black are the most popular and proven companies whose products can be found on the modern electrical equipment market.&Decker and DeWalt.
Choose an electrical planer should be depending on the tasks that it will perform. If you buy a tool for solving simple tasks (for example, processing boards for constructing a fence), then you will get away with a household option that will be much cheaper than a professional one.Back to table of contents
How to choose an electric plane according to the characteristics
In order to choose a manual planer, it is necessary to take into account its operational characteristics, among which the most significant are:
Table of the basic parameters of electrical planes.
- engine power;
- drum speed;
- width and depth of planing;
- sole characteristics.
Engine power. Its ability to work with solid wood will depend on the thickness of the planer. Also, this characteristic is one of the main indicators of the class of equipment: if it does not exceed 0.6 kW, then this is most likely a household sample intended for private use. If the power reaches 1.0 kW or more, then it will already be a professional tool that will successfully cope with any tasks. If you need to process several boards, then an electric planer with a capacity of up to 0.6 kW is quite suitable for you. The optimal power for private use is 0.8-0.9 kW.
The speed of rotation of the drum. The purity of wood processing directly depends on the speed of rotation of the drum. A normal speed is a value of 10,000 rpm. There are more high-speed planers. For example, Interskol and Makita are capable of speeds of up to 16,000 rpm, and Bosch up to 19,000 rpm.
Scheme of adjusting the depth of planing.
The speed of rotation of the drum allows you to understand the main difference between the ordinary plane from the electric. In most cases, electric planers are equipped with two knives. For example, if the rotation speed is equal to 11000 rpm, then this means that each knife in 1 minute comes into contact with the surface to be treated 11,000 times. That is, to perform similar actions with a simple plane you would need to do 22,000 movements.
Width and depth of planing. In domestic models, the depth of planing does not exceed 2.5 mm, and in professional models it can even reach 4 mm.
The greater the depth of planing, the higher the performance of the equipment.
The width of the planer can be processed for 1 approach depends on the width of planing. Most modern models have a planing width of 82 or 110 mm.
Weight. The electrical plane is a handheld equipment, so its weight affects the productivity of the operator. The weight of a domestic planer may be about 4-6 kg. A professional tool can weigh 9 kg.
Characteristics of the sole. The sole together with the cutting elements is the main contact surface of the electroplane. In a quality tool, it should be flat and smooth. To prevent airbags from occurring, small grooves should be carved on it.Back to table of contents
Choosing a manual planer for picking
When buying an electroplane, in addition to the performance characteristics, you also need to pay attention to the ergonomics of the tool and the availability of accessories. To work with a plane, it must be equipped with two handles. The front handle simultaneously acts as a depth gauge, that is, it can be used to select the depth of planing. It is recommended to purchase such equipment so that the depth step is 0.1 mm, and the scale starts from 0.
For folding, the electric plane is equipped with a ruler and side stops. In the presence of an angle stop, it is possible to process wood at an angle of 45 °. Many models come with replaceable mounts and drums, which allows you to use a plane as a machine, jointer, or knife sharpener.
Due to the presence of electronic sensors, it is possible to maintain a stable operation of the equipment: a constant number of revolutions of the drum, idling, smooth start, etc. For safe operation, the tool must be equipped with a protective casing and a lock function against accidental activation.
When buying a manual plane, if possible, consider all its characteristics. Hold the tool in your hands, it should sit comfortably in your hand and cause a feeling of confidence. Only in this case you will be able to make the right choice and buy such equipment that will successfully cope with all the tasks.
