The processing of metal sheets in small volumes can pose a problem of choice between different types of tools. With two or three blanks it is quite possible to cope with an ordinary hand saw without worrying about network eyeliner and other organizational problems. Full-format machines will help to service a dozen products in a few minutes, but it is irrational to acquire such equipment for domestic use. The optimal choice will be trimming for metal, 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, the key feature is the presence of a turntable. Thanks to this platform, the operator gets the opportunity to cut at angles. To ensure high accuracy of trimming, a fine-graded scale is provided on the same table, eliminating the need to perform measurements with individual devices. Moreover, the latest versions from major manufacturers are equipped with laser pointers indicating the cutting line. In some versions, trimming for metal also allows automatic broaching. In the process of cutting, it is not the user who moves the workpiece, but special grips at a certain speed. To simplify subsequent workplace maintenance activities, manufacturers equip trimming and dust extraction systems as an option. A construction vacuum cleaner (usually of the same brand) is connected through an external pipe, which, during the operation, blows chips with debris into a bag.
Specifications
In the selection, it is worth analyzing a whole range of parameters that will help to make 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 you bet 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-sheeted soft blanks.
- Rotation frequency. This indicator does not affect performance. Peak traction is still determined by power. But the possibility of changing the speed can come in handy just in cases if you plan to process blanks of different types. The maximum frequency reaches 5000 rpm.
- Disk size. Diameter varies on average from 150 to 355 mm. Moreover, the disc for trimming for metal is characterized by the presence of solders from solid alloys. They increase the efficiency and quality of processing.
- Type of sharpening. It is important to keep in mind 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 qualitatively with trimming soft metal, wood and plastic. The power potential of the model is average (1650 W), but it is enough to provide a cut depth of more than 90 mm. It must be emphasized that this trimming for metal is hardly suitable for professional cutting of material in construction or in large-scale production. Affect the lack of power and endurance when working in line mode. But this disadvantage is offset by the following advantages:
- A wide range of equipment, including a 255 mm disc, guides, a lamp for lighting, a bag for a vacuum cleaner, etc.
- Additional functionality in the form of spindle lock and soft start system.
- Reliability of a design.
Model "Devolt D28720"
In terms of performance, this is the opposite of the previous tool, as 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. A quick change of equipment, easy access to brushes even at home and ease of physical handling - all this determines the comfort of operation of metal trimming “Devolt D28720”. Reviews also emphasize a convenient cut with a vertical arrangement of 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. Power is also 2,300 watts, and the diameter of the cutting blade is 355 mm. The cut can be carried out both at a right angle and at a 45-degree angle. Among the features of the model can be noted the presence of quick-release clamps, triangular profiles for the direction and a massive protective casing. However, trimming for metal “AEG 355” is deprived with an additional optional feature. In particular, there are no longer high-speed support systems and smooth start-ups that have already become mandatory for such a power tool. But there is a spark arrester, a special compartment for mounting devices and keys. According to users, the saw provides stability of cut, high accuracy and productivity.
How to make trimming for metal with your own hands?
The cost of the cutting machine is 15-20 thousand rubles. The amount is considerable, so many home craftsmen decide to independently manufacture the unit. Of course, there is no question of a full-fledged assembly from garage appliances, but it is quite possible to implement such a tool on the basis of a more affordable angle grinder (grinder). Work activities will be reduced to the installation of the platform and the frame structure 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 countertop of the right size is cut with a notch for cutting workpieces. Next, a frame structure for trimming metal from a grinder is performed. With your own hands it will not be difficult to execute it from a pipe fixed to the desktop with bolts and welding. The functional part should 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 impose a metal ruler on the platform and provide guides.
Tool Tips
Before work, you should make sure that the tool is working, equipped with a whole disk (no cracks) and correctly connected to the network. Separately, security measures are checked - the casing, spindle blocker, dust collector, etc. Already during the cutting process, the working area should be monitored so that foreign objects do not accidentally fall into it. All fastening equipment, consumables and workpieces should be removed from the table. Management of trimming for metal is carried out smoothly and without jerking. The pressure on the workpiece, regardless of its size, must be performed with the same force throughout the entire sawing process - this will ensure smooth and clean edges. When working with longitudinal cutting, it is recommended to use rectangular guides and stops.
Conclusion
The segment of mounting saws is wide enough and it presents different models for metal processing. Specialized cutting machines, for example, allow you to cut products based on solid alloys. Such models are distinguished by powerful engines and reliable design. But there is also a class of less productive, but useful in everyday life universal saws. These include the “Makita LS1040F” trimming for metal considered above, which allows high-quality processing of aluminum and copper billets. The same unit will come in handy if you need to cut wood material. When choosing, do not forget about the additional features of the tool. Although the expansion of the functionality directly affects the price tag, modern security systems and devices for cutting correction will certainly not be superfluous.
