every revolution of the tool. So, going from a 2 flute bit to a 3 flute bit, the size of the chip is reduced by 33% if the feed rate or spindle speed (rpm) is not adjusted accordingly. A smaller chip will increase heat during the cut as the chips cannot be extracted fast enough and are re-cut into yet smaller particles. The resulting heat generated is very detrimental to tool life! Remember: Too big a chip load will decrease the finish. Too small a chip will decrease the life.

1-800-544-8436 SAFETY FIRST every field of technology. For the wood/composites industry, it has developed very extensive criteria/norms for the safe and effective operation of manufacturing machinery, cutting tools, clamping systems and many other accessories. It’s closest U.S. counterpart, ANSI (American National Standards Institute), does not have a detailed norm for cutting tools and accessories. When it comes to very specific tool design DIN NORM abbreviation for Deutsches Institut für Normung (often just referred to as Deutsche Industrienorm) is the German national institute for standardization of almost criteria with details such as minimum acceptable shank diameter based on the mass of the respective tool body being made, maximum knife protrusion beyond tool body (on insert tools) and countless other details that serve to protect both machine operators and the machine itself, in absence of such established norms in the U.S, we look to Germany’s stringent DIN standards to dictate what we do. While today’s CNC machining centers are equipped with state-of-the-art safety features such as curtain guards, contact mats, guard fencing and more, a cutting tool spinning at 16,000+ rpm still poses a risk if sub-standard tools and clamping systems are employed and safety warnings not followed. Partner with someone who meets the standard!

1-800-544-8436 MOST COMMON CLAMPING SYSTEM HSK-F 63 Developed in Germany, the HSK tool holder is the most widely used collet chuck on CNC routers and machining centers in the wood/composite industry today as it provides the highest degree of accuracy for high speed machining. A precision machined interface between spindle and tool, it is balanced to G2.5 spec for 25,000 rpm. Manufactured in accordance with DIN 69893, it is designed for use with automatic tool changers. HSK (Hohl-Schaft-Kegel), translated from the German language means hollow shank taper which is the part of an HSK tool holder that connects to the machine. This taper is machined to the highest precision, both radially and axially, of 0.0001 per DIN Norm. It’s important to purchase only the highest quality tool holders from reputable manufacturers to protect the machine spindle from potential damage.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
