A new series of high-speed circular cold saws

The circular saw is the most commonly used machine employed in processing metal and other materials. The reason for this lies in the fact that the metal circular saw is very com pact in construction, uses an inexpensive saw blade, which can be resharpened, and is very simple to operate on account of the relatively low cutting speed. These obvious benefits-and their wide application-speak for the use of circlular saws but their disadvantages cannot be denied.

These machines normally operated with HSS saw blades, which can only be used at very low cutting speeds on materials, which are difficult to cut. in addition these saw blades always require a cooling lubricant. Cooling lubricant not only causes problems relating to the disposal of chips, but there are also the questions of its preparation and disposal. The application of the cooling lubricants is particularly problematic in case of high requirements for subsection welding of the parts. The demands can generally be fulfilled only if the parts to be welded are washed after cutting. The additional step not only vreates additional cost, but it is also problematic from the ecological point of view.

More than 15 years ago, carbide tipped circular cold saw blades were developed and successfully used for cutting steel in the industry. The circular cold saw operates with thin cuts, using carbide tipped saw blades (1.8/2.2mm cutting width) with a diameter of 355mm.

With a cutting velocity of 1400RPM, this saw can dry-cut steel pipes, high grade steel, stainless steel pipes,profiles, angle bar, U and double-T profiles, SML pipes, plastic encased pipes and other steel profiles. When cutting with the Premium Super Dry Cutter the problem of the disposal of the oil-soaked chips and the coolant no longer exists.
