Working metal sheets in small quantities can make it difficult to choose between different types of tools. It is quite possible to handle two or three blanks with an ordinary hand saw, without worrying about the network connection and other organizational problems. Full-scale machines will help to serve a dozen products in a few minutes, but it is irrational to purchase such equipment for domestic use. The best choice would be metal trimming, which is characterized by mobility, performance and wide functionality.
Tool Features
Miter saws have many structural and functional differences from machine tools and jigsaws. As for the device of the tool, the key feature is the presence of a turntable. It is thanks to this platform that the operator gets the opportunity to cut at angles. To ensure high accuracy of trimming, a scale with fine graduation is provided on the same table, eliminating the need to take measurements with separate devices. Moreover, the latest versions from major manufacturers are equipped with laser pointers that indicate the cutting line. ATin some versions, metal trimming also allows automatic broaching. During the sawing process, it is not the user who moves the workpiece, but special grippers at a certain speed. To simplify the subsequent maintenance of the workplace, as an option, manufacturers equip trimmers and dust removal systems. A construction vacuum cleaner (usually of the same brand) is connected through an external pipe, which, during the operation, blows chips with garbage into a bag.
Specifications
When choosing, it is worth analyzing a whole range of parameters that will help you get an idea of the best choice. The main list of characteristics can be represented as follows:
- Power. The average value is in the range of 1000-3000 watts. If the stake is only on metal, then it is advisable to purchase a device with a potential of at least 1500 watts. At reduced power, it will be possible to work only with thin-leaved soft blanks.
- Frequency of rotation. This indicator does not affect performance. Peak thrust is still determined by power. But the ability to change the speed can come in handy just in cases where you plan to process workpieces of various types. The maximum frequency reaches 5000 rpm.
- Disk size. The diameter varies on average from 150 to 355 mm. Moreover, the disk for trimming for metal is distinguished by the presence of soldering from hard-state alloys. They increase the efficiency and quality of processing.
- Type of sharpening. It is important to havemind that the tooth shape of the saw blade can have a positive or negative angle. For metals, only the opposite, that is, negative sharpening, is used.
Model "Makita LS1040F"
This tool is universal. Its main advantage lies in the ability to cope with the trimming of soft metal, wood and plastic. The power potential of the model is average (1650 W), but it is enough to ensure a cutting depth of more than 90 mm. It should be emphasized that this metal trimming is hardly suitable for professional cutting of material in construction or in large-scale production. There will be a lack of power and endurance when working in streaming mode. But this disadvantage is offset by the following advantages:
- Wide set including 255mm disc, guide rails, light bulb, vacuum cleaner bag, etc.
- Additional functionality in the form of spindle lock and soft start system.
- Design reliability.
Dew alt Model D28720
In terms of performance, this is the opposite of the previous tool, since the power is already 2300 watts. Accordingly, the format of the saw blade has also increased - up to 355 mm. At the same time, the presence of a high-power electric motor did not reduce the ergonomic properties of the equipment. Quick tool changes, easy access to brushes even at home and easy physical handling - all thisdetermines the comfort of operation of the Dew alt D28720 metal trimmer. The reviews also emphasize a convenient cut with a vertical arrangement of the working equipment. In this mode, it is possible to cut thick workpieces with little physical effort on the part of the operator.
Model "AEG 355"
The tool is designed for cutting high carbon and steel alloys. The power is also 2300 W, and the diameter of the cutting blade is 355 mm. The cut can be made both at a straight and at a 45-degree angle. Among the features of the model are the presence of quick-release clamps, triangular profiles for guiding and a massive protective cover. However, the AEG 355 metal trimming is deprived of an additional option. In particular, there are no high-speed support systems and soft start that have already become mandatory for such a power tool. But there is a spark arrester, a special compartment for fasteners and keys. According to users, the saw provides stable cutting, high precision and productivity.
How to make a do-it-yourself metal trim?
The cost of a cutting machine is 15-20 thousand rubles. The amount is considerable, so many home craftsmen decide to make the unit themselves. Of course, there is no talk of a full-fledged assembly from garage fixtures, but on the basis of a more affordable angle grinder (grinder), it is quite possible to implement such a tool. Work activities will be reduced to the installation of the same platform and framestructure connecting the angle grinder and the table. For the main frame, you can use a channel, a corner and thick sheets of steel. By welding, a worktop of the desired size is assembled with a cutout for cutting blanks. Next, a frame structure is made for trimming metal from a grinder. With your own hands, it will not be difficult to make it from a pipe fixed to the desktop with bolts and welding. The functional part will have to be set in motion by a lever, which is also made of a pipe with a rubber sheath or a finished handle. For marking, you can put a metal ruler on the platform and provide guides.
Tips for using the tool
Before use, make sure that the tool is in good working order, equipped with a whole disc (no cracks) and properly connected to the network. Safety equipment is checked separately - a casing, a spindle lock, a dust collector, etc. Already in the process of cutting, the working area should be controlled so that foreign objects do not accidentally get into it. All mounting hardware, consumables and blanks must be removed from the table. Trimming for metal is controlled smoothly and without jerks. The pressure on the workpiece, regardless of its size, must be carried out with the same force throughout the sawing process - this will ensure smooth and clean edges. When working with longitudinal cutting, it is recommended to use rectangular guides and stops.
Conclusion
Segmentmounting saws is wide enough and it presents different models for performing metal processing. Specialized cutting machines, for example, allow you to cut products based on hard alloys. Such models are distinguished by powerful engines and a reliable design. But there is also a class of less productive, but useful universal saws in everyday life. These include the Makita LS1040F metal trimming discussed above, which allows high-quality processing of aluminum and copper blanks. The same unit is useful if you need to cut wood material. When choosing, do not forget about the additional features of the tool. Although the expansion of functionality directly affects the price tag, modern security systems and devices for correcting the cut will certainly not be superfluous.
