    Aftermarket Servo Door Manufacturers

    hey Gang - does anyone have any recommendations for manufacturers of kits to convert/add a servo door to existing CNC machines? Yes, I can obviously design and build custom ones, but why reinvent the wheel if I don't have to? Bonus points if you've done the install and have feedback on it...

    Planning for Swaging Force

    Hey Gang - Looking for some input/guidance on an operation I don't have any experience with for something I'm working on: I'm looking to expand (and swage seems to be the correct term, although others might apply) a 2.5" OD tube with an 11 gage wall to accept a bearing. ID will need to expand...

    Manufacturing Round Groove Conveyor Roller Grooves

    Hey Gang - I feel like I'm coming here with generally weird questions lately, that are only somewhat related to machining, but I always get good answers, so...... Anyone ever make round groove conveyor rollers? McMaster-Carr If you don't want to click through to the McMaster-Carr page: these...

    Order of Magnitude for Operational Cost of Robotic Weld Cell

    I posted this on one of the Industrial Robotics forums I'm a member of, but it's not real active over there, and I haven't gotten any input. I also asked my Fanuc Distributor, and haven't heard back from him (and will take it with a grain of salt when I do anyway.) Hey gang, trying to wrap my...

    Opinions for tolerance required on a "REAM" Callout?

    Hey Gang - Kind of a weird question: I have an old, old print with a thru hole callout for "REAM .501" The obvious thing to do is run a .501 reamer through it, but I don't like reamers, and my mill has very limited Z travel, so reamers don't really like me either. I would much prefer to...

    Technical/Manufacturing Drawings for Sporting Rifles

    Good Morning All, I'm on vacation and spending some time thinking and planning future fun projects. I happened across an article about defense distributed winning their court case, which got me thinking about all the guys making and selling XX% AR lowers, etc. Since I have the tools/machines...

    Machining Strategy of a part: Advice/Second Set of Eyes Please

    Looking at this print, material is CRS, tolerances are open, with the only really critical feature being the sharp corner called out by the asterisk. The 1.07 and 0.85 dimensions are full radius slots, if that isn't clear, and the 0.85 horizontal dimension is to a small flat. The radii in the...

    SolidWorks 2018 CAM - Lack of Dynamic/Trochoidal/Adaptive Mill Toolpaths?

    Hey guys - I'm currently looking at SW2018 CAM, and trying to figure out if I want to make the move to that from my current software. A couple of things concern me, and I'd like to verify them here with someone who's actually using it, because the sales guys I've been talking to seem very...

    Industrial Replacement/Equivalent for Circular Saw Process Automation

    I've currently got a process that is laid out by hand and then cut with a circular saw - think trimming down a piece from a 12" x 12" square to a 8" x 10" rectangle (or one of a million sizes in that general range.) Material is a soft polymer bonded to 1/16" or 1/8" aluminum or Alumalite. This...

    Sandvik RA200 Milling Strategies for Best Use

    Hey gang - I've got an old Sandvik Coromant RA200-016MN25-09M (1 in cutting diameter, 2 round inserts, more info on Sandvik site) and I have never used the thing, and never really used anything other then the typical end mills and whatnot, with the exception of facemills for facing off stock...

    Keyence XM Benchtop CMM

    Anyone seen or used one of these in person yet? Thoughts? Any idea on price? (No, I don't want to ask Keyence because they'll never stop calling me if I submit an inquiry. Relentless jerks.) A Coordinate Measuring Machine on a Whole New Level | KEYENCE America

    WTB Press Brake: 6'-8' x 1/4"+ Capacity

    Looking for a press brake in the 6'-8' length range, capable of doing up to 1/4" sheet. Want to stay away from anything with NC because we don't need it, and it's probably more trouble on the older machines than it's worth (for us.) This is not a production machine - it's for when we need to...

    Specification of Foam used in UniGripper/Piab Kenos/Schmalz FX

    Hey Gang – looking for some insight into the type of foam used in vacuum grippers similar to UniGripper/Kenos/Schmalz FX style of ‘flexible’ or ‘universal’ vacuum grippers. Thought someone here might have worked with it in the past (machining or waterjetting it) or have information on the...

    Help with Hydraulic Design

    Good Morning Gang I'm looking for some guidance (or maybe just a sanity check) on a really simple hydraulic system. I've got a double acting cylinder (3" bore x 60" stroke) I need to power. Max cylinder pressure is 3000 PSI, but I'll never need it all. The only reason I'm using a hydraulic...

    'Parting Off' on a 4th Axis in a VMC

    I've seen this done a bunch of times, and as I'm doing more and more 4th axis work, I decided this was something I wanted to try out. I looked around for a video, because I know I've seen it done a bunch of times, but I couldn't find one showing what I was envisioning. And yes, I did search...

    Getting Started with Macros on a Haas/Most useful Macros to be Using

    As I do more research into all the cool and useful things that can be done with macros, I feel more and more like I've been missing something obvious the entire time I've been programming a machine. I've tried to work through the macro section in the Haas manual (2001 VMC) but the lack of...

    Sandvik Coromant Facemill Selection Help

    Twofold question: what's the best use of square shoulder milling insert tooling? And what would be a good choice for a Sandvik Coromant facemill that would fit the same body as the below shoulder mill heads? A while back I bought a machine that came with a decent amount of tooling, most of...

    5C Vise/Dovetail Fixture

    Anyone know of an off-the-shelf dovetail fixture or small vise that's made to work in a 5C setup? I've been Googling around without any luck, and have hit the usual suspects (5th Axis, Lang, Jergens, Kurt, etc.) and I'm just not seeing anything. Danke.
