kevinj308 Posted May 17, 2014 Share Posted May 17, 2014 so i have started my mini trial of the GWizard. I do not see the 3/32 size mill listed and i am not positive of the steel these strikers are made of either. You'll need to type it in, I used .09375 and it rounded it to .0938. I set it up with .5hp and a max of 2500 rpm. Kept the tool stickout to .250 inches, that'll help with deflection. I kept the slider all the way to conservative. I don't know what the striker is made of either but I used a D2 tool steel, hardened. That'd be like a chisel or punch. Here's a shot of the set up screen. I know this sounds insane but it's recommending 2300rpm for a .030 deep cut and full slot. Take note of the feed however, only 1.4 inches per minute. Pretty slow!!!! and if it's a plunge cut it's only .3 inches per minute of feed. It's also recommending conventional milling. Which again I found counterintuitive. This was just one set up, you can play with the speeds and feeds and maybe find something that suits you more. Everybody's machine is different and I would NEVER argue with success. I'm just throwing this out there, might be worth the cost of one 3/32 mill to give it a try. And like straightup said, if you find a speed and feed that works for you write it down!!!!!! Keep a cut log for future reference. On a personal note I'd also suggest using at least a low pressure air nozzle to keep chips out of the cutter. Even a can of air like for keyboard cleaning. Anything to keep the endmill from cutting a hardened chip. I found that really helped my end mill life and performance. A lot of what gwizard has told me seemed wrong to me at first. Much higher rpm for cutters than I would have thought. Small cutters definitely need to go faster and 3/32 is pretty small. Link to comment Share on other sites More sharing options...

kevinj308 Posted May 17, 2014 Share Posted May 17, 2014 To be fair it was the first and only Glock slide I have cut to date so I really took my time to get the feel of the steel so to speak. I threw this into Gwiz, used .5hp and 2500rpm. Used hardened D2 tool steel, which was just a shot in the dark. Interesting numbers, 2300rpm!!!! I know for me using air to keep the chips out of the cutter made a huge difference. The cutter really didn't like cutting a super hardened chip.

dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 Ok so how does this look. I'm dumb to this but my wheels say 62.5 per turn? I average 13 full turns zero to zero for my full length cuts and about 4-5 for my short cuts. Sorry for being the FNG lol Link to comment Share on other sites More sharing options...

I'd say you need to make your hp .5 instead of 4, that makes a big difference. And if you click on the "more" button next to materials you can get a lot more options. I chose a hardened type of tool steel. I'm sure that striker is hardened. You could move the slider all the way over to turtle or conservative as well. That'll help compensate for the fact that we're using a table top mill without a lot of rigidity. Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 Ok I thought these where 4hp at least. Isn't .5 just half a horse power Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 The Rockwell on the strikers is like 60-70 Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 Added .5HP the D2 tempered+ hardened steel, It's showing 2272RPM 1.65IPM And a depth of .3 is 30thou right? Link to comment Share on other sites More sharing options...
kevinj308 Posted May 17, 2014 Share Posted May 17, 2014 Harbor freight claims 4/5 hp, Little Machine Shop says .5 or 1/2. I'd trust them to be more honest. My grizzly g0704 says it's 1hp but really its not. .3 is 0.300 thousandths or about 5/16. For 30thou it would be .030. .300 is kinda deep for a full slot on a small mill, but gwiz didn't seem to freak out. I'd still be a little cautious there. Super slow feed and at least air blowing on the cutter if you've got it. And I'd slide the slider over to the turtle. Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 yep slider is at the turtle now. changed to .030 for depth and now it reads 2500rpm and 1.816 imp Link to comment Share on other sites More sharing options...
kevinj308 Posted May 17, 2014 Share Posted May 17, 2014 That's for a full slot cut, if you're doing less than that your feed will increase. Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 Well it is a full slot but I figure take .001 per pass Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 Strght up sent me a pm with a 2500 speed and a 1/32 ball end and cut bout what i want to do in 2min but I have not been about to reproduce these times Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 what is the 62.5 per turn? Link to comment Share on other sites More sharing options...
kevinj308 Posted May 17, 2014 Share Posted May 17, 2014 what is the 62.5 per turn? 1/16 of an inch per turn. Link to comment Share on other sites More sharing options...
kevinj308 Posted May 17, 2014 Share Posted May 17, 2014 Strght up sent me a pm with a 2500 speed and a 1/32 ball end and cut bout what i want to do in 2min but I have not been about to reproduce these times I'm not understanding that. 2500rpm is about what we've been discussing, and what gwiz has been suggesting. Did you mean 3/32 mill? Then 2 inches per minute is pretty close to what gwiz says. Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 No he only had a 1/32" ball end. I dunno depth but looked close to mine and he made the cuts and was done in 2mins. 1 1-16 in in 13 turns correct? Link to comment Share on other sites More sharing options...
kevinj308 Posted May 17, 2014 Share Posted May 17, 2014 Full slot, how much depth do you ultimately need? Ballpark is fine if it's propritetary to what you do. Or send me a pm. Link to comment Share on other sites More sharing options...

I dunno depth but looked close to mine and he made the cuts and was done in 2mins. 1 1-16 in in 13 turns correct? Multiply 13 times .0625, its 0.8125. Do that in 30 seconds and you're feed is about right. Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 30 seconds for a 1/16 over 3/4 just looks SLOW in my head lol Link to comment Share on other sites More sharing options...
StraightUp_OG Posted May 17, 2014 Author Share Posted May 17, 2014 (edited) Yeah I used a 1/16 at 2500 at about 2ipm taking .010 per pass. Just to clear up my test info. Cut smooth as silk. Figured that would be a good place for Daniel to start. I made these cuts on a stock Glock striker. Edited May 17, 2014 by StraightUp_OG Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 Ok there here is lol!!! And ok .10 per pass lol I was doing .001 lol I'm a dumb ass lol I can't read good Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 17, 2014 Share Posted May 17, 2014 Three passes at .010 would deff be quicker than what I did at 3a lol Link to comment Share on other sites More sharing options...
