The machines consist of a bed, an electric motor, pulleys and a web with teeth, without them and electric spark.
The machines consist of a bed, an electric motor, pulleys and a web with teeth, without them and electric spark.
The more pulleys (from two to four), the longer the web can be used.
For the operation of these machines, a voltage of 380 V is used, rarely 220 V. The machines are divided into vertical (the canvas in the working area moves vertically relative to the table) and horizontal (the canvas moves parallel to the table).
They are also divided into procurement, separation and carpentry.
Metal saws come in 4 classes: 1.
Saws of the 1st class are the most versatile and expensive.
They can process both aluminum and hardened steel with high precision and processing speed.
2.
Machines of the 2nd class are cheaper, but in terms of cutting quality they are not inferior to saws of the 1st class.
They provide a vertical and angular cut. 3.
Saws of the third class are divided into manual, semi-automatic, automatic.
They are not as accurate and productive.
They are used where the cutting quality is not critical. 4.
Saws of the 4th class are household tools for making piece products at home or in the workshop.
Wood saws have higher productivity than circular saws and electric jigsaws.
They are used in logging.
According to the type of cloth in the machine, there are: narrow-profile (web width up to 60 mm) for working with soft wood, panel material and non-thick timber with low productivity; wide-profile (web width up to 200 mm) for both fine processing and harvesting of thick logs.
The cost also depends on the type of machine: automatic – the most expensive, semi–automatic – average in price, manual - the cheapest.
