Tools for cutting aerated concrete
When choosing a tool to cut aerated concrete blocks, consider subtleties like:
- Properties of the cutting tool.
- Number of tasks to be solved.
The artisans also consider the size of the blades, since a hand saw will suffice for small-scale material processing during do-it-yourself projects, but a powerful saw is required for larger-scale work involving aerated concrete.
Every day, a professional electric saw for aerated concrete can be operated for over six hours with multiple loads at once. Although it costs more than straightforward inventions, it works faster and with greater efficiency.
Avoid buying the priciest models of tools based solely on advertising when searching for a suitable tool. A basic hand tool will be required for a novice. After that, you can proceed to professional-grade items.
Manual
The following hand tools’ characteristics should be taken into account when determining how to cut aerated concrete:
- Hacksaw with a hard blade. It has a short blade and can be used to work with gas blocks no more than 20 cm thick. Cutting aerated concrete blocks with such a saw is convenient and fast.
- Hacksaw with an enlarged and flexible cutting element. To make the cut smooth and accurate, you should adhere to the cutting technology.
Advantages
The following are some benefits of the hand saw types mentioned:
- Ease of use.
- Absence of deformation processes during intensive use.
- No chips on the surface.
- Can be used for longitudinal and transverse cutting.
- Optimal price.
Disadvantages
But the hand tool has a lot of drawbacks in addition to its benefits. The first thing that needs to be done is buy a metal square because it will stop distortions during incorrect cutting. Furthermore, cutting work is labor-intensive and skill-dependent.
In order to achieve superior cutting, it’s important to choose the right saw for aerated concrete. Ready-made kits made especially for these kinds of building supplies are available for purchase.
How to saw with a hacksaw using a miter box
A miter box is a special tool that can be used to make cutting aerated concrete blocks more comfortable and effective. It appears to be a two-letter P-shaped wooden structure that is rectangular and joined at the corners.
These components are separated, guaranteeing cutting. You must fasten wooden blocks to both sides in order to strengthen it. The dimensions of the gap are chosen to allow the saw to move freely without "walking." Because waste will gather there, the gap in the platform is a little bit wider than in the side portion.
It is better to select large, thick-metal corners to ensure the ideal level of rigidity. A hacksaw is inserted into the opening left by the letters "P" and the block that needs to be cut is placed inside.
You can maximize cutting accuracy and boost cutting efficiency with such a basic tool. The following actions must be taken when the workflow is launched:
- Use a pencil and ruler to mark.
- Then you should make shallow cuts along it.
- After this, you can use the miter box: a block is placed in the work area, and then the necessary fragments with marks are cut off.
It takes no more than five minutes to saw a standard 400 x 250 mm block with a density of D500 using a hand saw. The time costs will go up if a large structure needs to be built.
Band
A closed band of extremely strong metal powers an electric band saw, a professional instrument. The device’s support for height adjustment and optimal performance indicators are its advantages. A cutting blade can be used to create a superior longitudinal or curly cut.
To arrange U-shaped blocks from basic structures, utilize chain models. Deep cleaning of the working parts from lubricants and oils in a timely manner is crucial to prolonging the equipment’s service life and keeping it in operating condition. If not, dust will start to gather on the sticky surface and quickly wear down the working parts.
To get neat, effective results when cutting aerated concrete, selecting the appropriate saw is essential. You will learn about the various kinds of saws that are available, how they work best with aerated concrete, and the best block-cutting techniques in this guide. Whether you’re a professional or a do-it-yourself enthusiast, knowing these fundamentals will help you choose the right tool for the job and guarantee a clean, accurate cut every time.
Reciprocating saw
An electric tool that looks like a jigsaw is called a reciprocating saw. Its design makes room for both a cutting element and a sturdy body.
You can cut straight or inverted with a saber saw by using one of the many attachments available. It gets its name because it has flat cutting parts that resemble sabers.
These components have rotary-translational motions as they advance. The block indicates the cutting speed. The engine power and cutting blade length of various types of saber saws vary.
There are oscillations with an amplitude of 2-5 cm and a frequency of movement exceeding 3000 per minute. A new blade can be used in place of the damaged one. Through the ventilation holes, the thermal energy released during cutting is released.
- High cutting accuracy.
- High efficiency of use.
- The ability to change the cutting depth.
- The ability to adjust the blocks to specified dimensions.
- The ability to cut grooves for wires.
One of the equipment’s drawbacks is its comparatively high cost, which ranges from 5,000 to 14,000 rubles. The apparatus includes metal and woodworking blades.
Get a specialized blade if you must process aerated concrete structures. Because saws are not very popular, it is not available in every store.
Alligator saw
A traditional saber product is sometimes mistaken for an alligator saw by unskilled artisans. Still, there are some differences with this model. When operating, the Alligator moves the saw blades in a manner similar to that of a crocodile’s jaws.
These devices, in contrast to saber models, do not have reciprocating movements because a fixed saw bar makes the cut.
- High engine power, which allows you to process thick blocks of aerated concrete.
- Due to the counter movement of the blades, the block remains stable.
- The design provides for a blade brake and switch locking.
- There is enhanced protection against dust.
- Using the saw is quite convenient.
- Replacing consumables is easy.
One of the product’s drawbacks is its high price. As a result, buying such a tool is only appropriate in situations where it will be used professionally on sizable construction sites.
Electric chain saw
Due to its versatility, the electric chain saw is a common tool in home workshops. The components of the device are as follows:
- Cutting element.
- Saw bar.
- Tension mechanism.
- Chain lubrication system.
- Blocking shield.
The inner section is constructed as follows: two sprockets are passed through by a closed loop that travels along a guide. At the end of the guide, the front sprocket is driven and fixed. There is an additional component installed on the drive shaft at the back. It initiates the chain movement when it is connected to an electric motor. On the body, there is a protrusion close to the rear sprocket.
The saw’s tension must be properly adjusted by tightening a special screw on the body in order for it to operate smoothly. The blades that are fixed to the contour move in a circular motion to facilitate the cutting process.
Pros
Chain saws are thought to be the best tool for organizing U-configuration blocks by experts. The final cut explains this. Additional benefits consist of:
- Increased material processing speed. This is explained by the increased performance of the engines.
- Comfortable weight balance: with such a saw, you can make a high-quality cut at an angle and overhead.
- The presence of guide rails in the kit, the length of which varies from 30-40 cm.
Chain models have the benefit of being relatively inexpensive.
Cons
Given that chain saws are meant to be wood processing tools, their primary drawback is the quick deterioration of the cutting blade when not being used for that purpose. It is preferable to purchase a special chain with carbide soldering to avoid such an issue.
Although it costs more than a basic chain, it is more durable. These devices come in a variety of models with various features and attributes in Moscow.
Excessive chain stretching and overheating are seen during cutting. Consequently, in order to get the chain back to its initial length, the master needs to remove one link. You should promptly turn off the equipment to avoid overheating.
The sprocket teeth become worn down and become unusable if you have to work in hard conditions for extended periods of time. Although changing sprockets doesn’t need a big financial outlay, it is a time-consuming procedure because you have to call a service center to find the best part.
When gas silicate blocks are used frequently, dust builds up and the electric motor becomes fearful. Consequently, the saw loses its functionality and cannot be fixed.
