Tool structure

The design resembles an angle grinder in appearance. The body is made of ABS plastic. An engine is installed inside it. The front part is equipped with a multi-stage gearbox, which is protected by a metal casing. Its function is to convert the rotational motion of the spindle into reciprocating motion. Thanks to this, the equipment comes into action.

The working unit consists of a static element and moving parts. When metal is passed between them, its structure is destroyed along the cut line.

The design of electric scissors also includes:

• protective plate-shield;
• handle;
• electrical cable.

Care instructions

In order for the scissors to last a long time and not cause trouble during operation, you need to devote time to their maintenance:

1. Make sure that the cutter always remains sharp and replace the blades in a timely manner. This will protect the motor from overloads.
2. Work intermittently. Ideally, for every 10-15 minutes of work there should be 5 minutes of rest.
3. Do not work in damp and dusty conditions, so as not to cause a short circuit or clogging of the ventilation holes on the device body.
4. Clean the cutting unit and ventilation grilles periodically.

Types of scissors and their purpose

The universal hand tool has a wide range of applications.

There are many types of scissors, each of which differs in design features, appearance, size, weight, and technical characteristics.

Hairdressers

Hairdressers use straight models with a standard sharpening.

The tool provides a perfectly even trim of hair, beard or mustache.

Thinning devices with a serrated cutting edge are designed for thinning hair, trimming bangs, and performing a stylish, modern haircut.

There are also universal flag scissors with shaped blades.

They are widely used by stylists and hairdressers; they are suitable for both cutting and thinning.

Garden

Tools with a reinforced design and reliable blades are used for cutting branches and giving an aesthetic shape to bushes.

This type also includes special devices for cutting grass.

They are, of course, inferior to lawn mowers.

But with their help you can carefully remove excess in hard-to-reach places, near stones, statues, near the curb.

For metal

There are two types of scissors.

Monolithic models have a one-piece construction.

Working parts are made of durable steel.

Such devices are able to cope with increased loads.

Compound scissors are intended for professional use.

They can be used to cut roofing materials into pieces.

Kitchen

You can't do without scissors in the kitchen either.

Models that belong to this type are used for cutting rabbit, chicken, and quail carcasses.

They cope with the task faster and more accurately than conventional knives.

For cutting greens, there are products with several cutting blades.

Stationery

They can be equipped with long or short blades and always have comfortable handles.

The scope of application of products of this type includes cutting sheets of paper, cutting out figures, appliqués, handicrafts, etc.

Hydraulic

This type of scissors is used for cutting metal rods and wires.

They can be used to make perpendicular or angled cuts.

Lever design systems ensure a smooth transition of pressure from the drive to the cutting elements.

Handles are needed to secure the device.

Medical or surgical

These scissors are designed for cutting soft tissue, bones, and cartilage during surgical operations.

Products are divided into the following types: guillotine, hinged.

These in turn are divided into many different types.

For each type of operation, a different tool is used.

Electric scissors

The instruments are presented in several modifications and are divided into several types.

Sheet shears are used to dismantle metal structures and cut sheets up to 5 cm thick.

According to the principle of operation and design features, they resemble household ones, they are distinguished by high productivity, compact size, reliability and functionality.

Splined ones are equipped with several knives, cope with folds, and do not deform the steel sheet.

Electric scissors of various types are convenient to use, productive, and increase the productivity and effectiveness of the work of the master.

Die-cut or die-cutting models are widely used for metal processing.

Their design consists of two main elements: a matrix and a punch.

Models can be used to make a variety of cuts: according to a template, straight, curved.

Nibblers produce a clean cut and there are no signs of deformation on the workpiece.

In addition, you can cut not only from the edge of the sheet, but also from the middle, but first you need to make a hole in the metal.

These are not all types of scissors, but only the main and most popular ones.

An interesting variety are knife models designed for straight and shaped cutting of metal.

The power tool is equipped with two knives: movable and fixed.

The cutting is smooth, precise, without waste.

But roller ones are used in roofing and fence construction.

With their help, you can easily and quickly cut metal up to 1 mm thick into pieces of the desired size.

There is a wide range of sewing or tailor's scissors.

There are models for cutting thin and thick fabrics, shaping edges of products, cutting threads, cutting out patterns, etc.

Criterias of choice

When purchasing electric scissors, you need to pay attention to many different factors:

1. Power. Varies in the range of 300-650 W. A powerful tool is always better, because... it allows you to make a deeper cut. But it must be taken into account that an increase in the power characteristics of the motor is accompanied by a loss of maneuverability.
2. Knife stroke frequency. The higher this indicator, the more accurate the cut. However, with thick workpieces it is preferable to work at a low speed, so the best option would be a tool with a function for adjusting the speed of the knife.
3. Maximum metal thickness. Varies from 0.3 to 16 mm. When assessing this parameter, you should also take into account what material the scissors are intended for: soft or hard steel, aluminum, composite, etc.
4. Material of cutting elements. Most cutters are made from chrome-molybdenum and chrome-vanadium alloy, but the most durable blades are those made from chrome-nickel or high-carbon steel.
5. Maneuverability. It is inversely proportional to the turning radius of the scissors: the smaller the radius, the higher the maneuverability.
6. Ergonomics. The tool should be comfortable to hold with one hand. However, for processing thick metal, an additional removable handle will not be superfluous.
7. Launch node. The operating mode lock button must be located in an accessible place so that it can be pressed by the finger of the operating hand.
8. Power source: Built-in battery. The best option for working on the roof and in hard-to-reach places. In addition to ease of use, the advantage of such devices is that there is no risk of damage to the cord. The only but significant drawback of such devices is low power (maximum workpiece thickness is 1.5-2.0 mm, recharging is required every 50-70 meters).
9. Mains powered. They allow you to operate with a workpiece on a workbench without thinking about charging and limiting productivity.
