This design allows the use of this equipment in production for sawing products from various materials, non-ferrous and ferrous metals, high alloy steels and stainless steel, aluminum, plastic and other polymers.
The compactness of the equipment makes it universal for use in confined spaces in a manufacturing enterprise. The frame with a saw tape rotates at an angle of up to 45 degrees. A smooth adjustment of the rotation speed is not provided, the change of the rotation speed is carried out discretely using a V-belt transmission. Given the very low price, this equipment is an excellent solution for small needs in terms of cutting parts.
Another Proma band saw used for processing small volumes of metal blanks. The Proma PPK-115 band saw differs from the previous model in the size of the processed workpieces. 100 by 150 mm, while the PPK-90U cross-section does not exceed 90 mm. The mass of the saw makes it easy to move it from place to place.
Due to the mass of equipment at 19 kilograms, it can easily be transferred to another place of work. Model JET J 349V is a professional equipment for cutting workpieces with a cross section up to 125 mm, at right angles and at 45 degrees. Excellent quality saw allows you to do without additional processing. A device with an installed saw band is supplied, which allows you to immediately start working with the tool.
The JET HVBS-56M machine allows you to process small batches of metal workpieces with a cross-section diameter of up to 1254 mm. The equipment has a heavy foundation for reliable installation in the enterprise. Due to the presence of built-in wheels, this band saw can be easily transported.
