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

For the wood/composites industry,it has developed very extensive criteria/norms for the safeand effective operation of manufacturing machinery, cuttingtools, clamping systems and many other accessories.It’sclosest U.S. counterpart, ANSI (American National StandardsInstitute), does not have a detailed norm for cutting toolsand accessories.When it comes to very specific tool designDIN 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 diameterbased on the mass of the respective tool body being made,maximum knife protrusion beyond tool body (on insert tools) andcountless other details that serve to protect both machine operatorsand the machine itself, in absence of such established norms in theU.S, we look toGermany’sstringent DIN standards to dictate whatwe do. Whiletoday’sCNC machining centers are equipped withstate-of-the-art safety features such as curtain guards, contactmats, guard fencing and more, a cutting tool spinning at 16,000+rpm still poses a risk if sub-standard tools and clamping systemsare employed and safety warnings not followed.Partner with someone who meets the standard!

1-800-544-8436MOST COMMON CLAMPING SYSTEM HSK-F 63Developed in Germany, the HSK tool holder is the mostwidely used collet chuck on CNC routers and machiningcenters in the wood/composite industry today as itprovides the highest degree of accuracy for high speedmachining.A precision machined interface between spindle andtool, it is balanced to G2.5 spec for 25,000 rpm.Manufactured in accordance with DIN 69893, it isdesigned for use with automatic tool changers.HSK (Hohl-Schaft-Kegel), translated from the Germanlanguage means hollow shank taper which is the part ofan HSK tool holder that connects to the machine. Thistaper is machined to the highest precision, both radiallyand axially, of 0.0001”per DIN Norm.It’simportantto purchase only the highest quality tool holdersfrom reputable manufacturersto protect themachine 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.
