Can anyone tell me what type of cuts it's supposed to be used for? And why are they called "cranked" tools?</p> <p>Cheers<br /> Dorian </p> http://www.todaysmachiningworld.com/forum/topic/breaking-taps-making-parts-high-strength-low-alloy-60-and-80ksi-minimum-yield#post-49 Wed, 11 Feb 2009 16:37:11 +0000 Anonymous 49@http://www.todaysmachiningworld.com/forum/ <p>Our company has been processing a family of parts made from high strength, low alloy, 60 and 80ksi minimum yield steel plate. After laser cutting and Mig welding, we machine a series of holes using conventional drills, spade drills, boring bars and taps. The problem is we keep breaking taps of all different sizes, 5/16"-18, 3/8"-16 and even 3/4"-10. We have approached a number of industry representatives who keep moving the taps to successively more expensive versions intended for alloyed cutting, but they don’t solve the problem. Until this thing gets fixed, in order to produce a good part we need to destroy the tap that was in the hole, clean the hole out, weld it shut, and remachine the hole by hand. As you can imagine, this issue is killing delivery performance and profitability. </p> http://www.todaysmachiningworld.com/forum/topic/inconel-gtd-444#post-399 Wed, 15 Apr 2009 10:41:34 +0000 Anonymous 399@http://www.todaysmachiningworld.com/forum/ <p>Has anyone machined any GTD 444 material? i am trying to get a handle on this turbine blade material and was looking for some feedback from anyone that might have done some. </p> http://www.todaysmachiningworld.com/forum/topic/indexable-carbide-inserts-single-point-turning-benefits-of-molded-vs-ground#post-52 Wed, 11 Feb 2009 16:46:02 +0000 Anonymous 52@http://www.todaysmachiningworld.com/forum/ <p>Currently we are utilizing indexable carbide inserts for single point turning processes more frequently in our shop. It appears that most of these inserts are available in “Molded” or “Ground” tolerances. Can you tell me the benefits of one over the other? And how will I see the performance advantages from the more expensive “Ground” inserts? </p>
