We are trying to machine bar 1/8 SST304, but we have problems with tool wear and chip control, we are using a SECO DCMT 070204 F1 CP500, the cutting conditions are RPM 8000, F=0.04 mm/rev DOC=0.8 mm. Got any tips to improve the process? </p> http://www.todaysmachiningworld.com/forum/topic/headstock-collet-cap-is-stuck-tight-on-the-spindle#post-308 Tue, 24 Mar 2009 14:49:53 +0000 Anonymous 308@http://www.todaysmachiningworld.com/forum/ <p>Whenever we finish up a long running job we find that our headstock collet cap is stuck tight on the spindle. It takes a considerable amount of time and effort to remove it. Is there any way to prevent this in the future? </p> http://www.todaysmachiningworld.com/forum/topic/turning-miniature-parts-in-titanium#post-378 Thu, 09 Apr 2009 12:39:36 +0000 Anonymous 378@http://www.todaysmachiningworld.com/forum/ <p>I was hoping someone could help me with a problem. I am using a Tsugami BW 12 swiss to turn a 6AL/4V Ti part .5 mm at the tip back 1.25mm then neck down to.3mm for a run of 14mm to a diameter of .6mm, My problem is when I bring my back turning tool down to the .3 diameter it just tears off the larger .5 diameter tip.<br /> Any suggestions or comments would be most helpful. </p> http://www.todaysmachiningworld.com/forum/topic/safety-issues-when-running-lights-out#post-205 Wed, 04 Mar 2009 15:54:27 +0000 Anonymous 205@http://www.todaysmachiningworld.com/forum/ <p>We are a small shop in the Midwest, and are interested in going lights out with our Swiss CNC operations. We think it could benefit our productivity greatly, but logically we are very concerned about safety issues. Some shops have said great things about running machines unattended, but I’ve also heard horror stories about fires or other things going wrong. What measures should I take to make sure lights out operations run smoothly? I’m worried I won’t be able to sleep at night while the machines are running solo. </p> http://www.todaysmachiningworld.com/forum/topic/the-tolerance-is-too-tight-for-a-hollow-mill-know-a-better-end-mill-or-method#post-310 Wed, 25 Mar 2009 16:48:12 +0000 Anonymous 310@http://www.todaysmachiningworld.com/forum/ <p>We are running a shaft on our CNC Swiss that has an eccentric diameter on one end. We tried picking off the shaft and milling the eccentric with an end mill but could not get the required surface finish. The tolerance is too tight for a hollow mill. Is there a better end mill or method we can use? </p> http://www.todaysmachiningworld.com/forum/topic/is-star-cnc-leaving-the-usa#post-175 Wed, 25 Feb 2009 23:56:56 +0000 Anonymous 175@http://www.todaysmachiningworld.com/forum/ <p>Is star cnc leaving the US market. They took 90 days to get toggles (chucking levers for old brownie guys) and 80 days to get a coolant pump. There parts people didn't think anything about saying we'd get the parts when we get them. </p> http://www.todaysmachiningworld.com/forum/topic/stripped-turret-bolt-holes#post-71 Thu, 12 Feb 2009 18:35:55 +0000 Anonymous 71@http://www.todaysmachiningworld.com/forum/ <p>Hi all,<br /> Just getting a 2nd opinion<br /> I have some oldr E16 J citizens that have many stripped bolt holes in the #1 turret--To many hammer mechanics here and over the years. Don't know why everyone wants to tighten bolts like a lug nut to machine .250 and down but they do.<br /> I was going to go the helicoil route on these but wondred if anyone had another fix.<br /> TRR </p> http://www.todaysmachiningworld.com/forum/topic/cant-accurately-control-depth-of-tap-on-cnc-swiss-lathe#post-53 Wed, 11 Feb 2009 16:50:40 +0000 Anonymous 53@http://www.todaysmachiningworld.com/forum/ <p>We can’t accurately control the depth of the tap on our CNC Swiss lathe. The type of component we are making has a blind hole that goes .200” deep. The threads are 6 -32 and need to have a fully formed thread of a minimum depth of .185”. The tool is a thread forming tap with a blunt point. We are using a Floating Tap Collet, and we program about 10% slower than the tap pitch, stop the spindle, slight dwell, then feed off at 100% of the tap pitch. We’ve tried many variations of this method with different spindle speeds, different floating collets and different tool positions, however, we still cannot accurately control the depth. One of the issues of not being able to control the depth is that we “bottom out” frequently and break the tap. Down time, tool cost and scrap material is eating into our profit margin for this job. </p> http://www.todaysmachiningworld.com/forum/topic/drilling-316-stainless#post-47 Wed, 11 Feb 2009 15:39:57 +0000 Anonymous 47@http://www.todaysmachiningworld.com/forum/ <p>Have a couple of Citizen C16's in the back of my garage on my own. I'm trying to drill a .065 hole .625 deep in 316 Stainless. No thru coolant. Have checked centerline. I've tried RPM's from 900 to 3150 and feeds from .001 to .002. Used cobalt, carbide, cobalt TiAIN coated. Have went thru about 35 drills so far. The most parts I've ran with one drill is about 10. Any suggestions? </p> http://www.todaysmachiningworld.com/forum/topic/hex-stock-has-twist-in-bar-when-milling-slot-on-citizen#post-33 Wed, 11 Feb 2009 05:55:57 +0000 Anonymous 33@http://www.todaysmachiningworld.com/forum/ <p>I’m milling a slot along the length of the part on .875 aluminum hex parts with a Mitsubishi M635 controlled Citizen-Cincom C32. In the process, my hex stock sometimes has a large twist in the bar, resulting in up to 8 degrees of rotational error from the hex flat to the milled slot. What can I do to get rid of this error? </p> http://www.todaysmachiningworld.com/forum/topic/reducing-setup-time-on-cnc-swiss#post-30 Wed, 11 Feb 2009 05:45:28 +0000 Anonymous 30@http://www.todaysmachiningworld.com/forum/ <p>We are working on reducing setup times on our CNC Swiss. Our people spend a lot of time developing a setup that faces the part with every tool to a set center height.

The part ends up with a square flange in between two turned diameters. The square has a toleranced corner break on both sides of the square all the way around. We are milling it using a pointed end mill at 20 IPM. It takes 30 seconds which is killing us. Is there a better way? </p>
