Therefore, it is necessary to compromise and select the speed that best apply to the material. Large deviations will result in a shorter life and reduced cutting ability. Too low a speed is always better than too high a speed.If the deviations are too large, a frequency changer can be installed in order to get variable speeds. A frequency changer can be installed by most electricians.Speed, Feed & Tooth AnglesSpeeds are listed in SFPM (surface feet per minute).Feeds are listed in inches per minute.SFPM can be changed to RPM (revolutions per minute) based on the blade diameter as follows:RPM = SFPM x 3.819 divided by the blade diameter in inchesFeedChip load per tooth is independent of the speed. The correct feed can theoretically be calculated from a chip load of 0.004″(0.1mm) per tooth per revolution. In practice, the maximum feed is determined by the stability of the machine, the clamping and the capability of the motor. The chips are also an important factor determining the feed and they should always be the correct color and shape. Basic feeds listed in inches per minute can be found in the table on the previous tab. This is the basic feed and it can and should be increased by production cutting on stable machines or by using special blades.ChipsToo low a feed:Proper chips are not formed, only “metal crumbs”.The blade is worn excessively and life is reduced.Too high a feed:Discolored chips that weld in the gullets.There is great risk that the blade will break.The correct feed:The chips are nicely rounded, uniform and bright.Maximum use and benefit of the blade.Chips:FluidsFluid is used for cooling, flushing away chips and lubrication.Use a recognized product and follow the suppliers instructions carefully.

As a rule there should be 3-6 teeth in the cut.As a blade is resharpened, the tooth pitch is reduced. Therefore, retoothing can be necessary occasionally.The blade speed depends on the material to be cut. For the standard construction steel it should be about 50 rpm when using a 11″ blade.Feed is measured as the chip thickness per tooth per revolution (max. 0.1 mm – .004″) but is generally listed as inches per minute.Using the correct feed, the chips are bright, even in size and nicely rounded.Plenty of fluid must be used when cutting. Mixture 6-10%.Resharpened blades always have to be “run in”. Make 6-8 cuts with normal speed and about 25% of normal feed.If “pick up” occurs, the blade should always be dismantled and retoothed.Thorough cleaning of the blade and flanges before mounting is very important and the backlash in the device pins taken out. This can be done by putting slight pressure against the face of the tooth in a direction opposite to that of the saw rotation as the blade is being clamped.When purchasing new blades, it is important to be aware of the blade material, bore tolerance, possible surface treatment and side run out.Circular saw blades should always be resharpened on machines that secure an even tooth pitch. Resharpening with coolant improves the blade life.Tooth geometry must be adjusted to the work piece. For example when cutting stainless and aluminum, special ground blades for these materials should be used.Selecting # of TeethNumber of teeth can also be listed as tooth pitch, which is the distance from tooth tip to tooth tip and is measured in millimeters.The tooth pitch used depends on the size and the material to be cut.In the table below the tooth pitch in mm is listed and in the table on the next page the number of teeth is listed.Material to cut10-20mm20-40mm40-60mm60-90mm90-110mm110-130mm130-150mm150-170mmCast Iron4681114161618Soft steel/ Alloy steel68101214181818Profiles: Wall thickn. 1/10 dia.4681114161618Profiles: Wall thickn. 1/20 dia.3456681012Profiles: Wall thickn. 1/40 dia.23455666Solid stainless4681114161618Solid aluminum48121416182020Profiles aluminum4681010121212Plastics4681010121212Copper68111417182020Brass57101216181820Main rule: 3-6 teeth in the cut This rule is not used when cutting thin walled tubes, profiles, brass, copper and aluminum.

Feed Per Tooth Calculation in Gear Manufacturing

Calculations.Standard Tooth Forms: ImageRetoothingAs a blade is resharpened several times, the tooth pitch is reduced. Therefore it can be necessary to occasionally retooth the blade in order to obtain the correct tooth pitch for the job.This is especially important for high production cutting of tubes.It is easiest done by letting your resharpening service retooth the blades when they reach a set minimum tooth pitch.Pick upPick up is one of the most common problems when cutting steel with HSS cold saw blades.Pick up has occurred when bright pieces/deposits of material are welded to the side of the blade. This makes the side of the blade uneven and substantially reduces the cutting ability.Pick up occurs due to friction between the blade and the material.Pick up is especially a problem when cutting stainless.Pick up occurs as a consequence of these cutting conditions:lack of or wrong cooling/lubricationtoo many teeth in the bladetoo heavy a feedlack of cleaning away the chips (brush and fluid)lack of cutting ability/grindingPick up will increase the thickness of the blade and result in the blade breaking. When pick up occurs, the machine must be stopped at once, the blade dismantled and retoothed. Pick up cannot be prevented by a special grinding of the blade and can only be removed by retoothing the blade. Grinding or other mechanical actions to the side of the blade will not solve the problem and it can easily make it worse. Brass is traditionally one of the materials, which demands that the speed and feed are correct. The speed and feed must be relatively high or heavy vibration occurs resulting in blade breakage. For cutting materials not mentioned in this guide, contact your supplier of tools or resharpening.Blade qualityWhen buying HSS blades, or trying to find the best cold saw blade for your application it is essential to be aware of the following: The blade must as a minimum be manufactured in M2 quality steel.Side run out tolerance should as a minimum not exceed 0.01% of the blade diameterCenter bore should be H7 tolerance to ensure stisfactory roundnessBlades for general use should have a surface coating such as the standard steam oxide treatment (black surface) to reduce frictionResharpening qualityCorrect resharpening is of extreme importance for the life and cutting ability of a blade.Demands for resharpening include:correct tooth geometry (tooth pitch, form and depth)uniform tooth pitchresharpening with coolantroundness tolerance max. 30 µcorrect beveling (tooth form B W and HZ)minimal yet adequate resharpeningWhat is a cold saw?A cold saw is a type of power tool used for cutting metal.
