1.0 INTRODUCTION
The CPO-275 Cold Saw is designed to cut solids, tubes, flats and other profiles in grades of material
that range from hot and cold rolled steel, annealed tool steels, stainless, aluminum, brass, copper,
synthetics and extrusions.
Cold sawing is a process similar to a milling process. In most cases, this, combined with the self
centering vise feature, gives a finished cut that does not require any secondary machining or de-burring.
Since milling spindle speeds are used in cold sawing, there are several things that are required to
achieve quality results. The selection of the proper pitch (number of teeth) on the blade and the proper
spindle speed for the type of material being cut are critical. Proper material clamping and a good
quality coolant are also important.
Cold sawing has several advantages over band saws and abrasive saws. Besides the mill quality cut, cold
saws have the ability to generate faster cutoff times than band saws.
There are no sparks and excessive noises that are associated with abrasive cutoff saws.
Cold saws also offer the advantage of blades that can be re-sharpened until the diameter of the blade
will no longer cut through the material. The self centering vise allows for easy changeover to special
clamping jaws, for profiles and extrusions. Having two spindle speeds enables the user to cut a wide
range of materials.
By adding the power vise and power down feed options, the saw can be converted to a semi-automatic
machine at a very reasonable price.
