    FS: 2x OV 6x17.5 Gen4 bases + carriers

    I'm selling two Gen 4 OV vise bases. 6x17.5, includes the base and screw but no jaws. Condition is used but very good. I'd prefer a local (NorCal) sale but will ship at cost. Only selling them because I needed to get new ones with a 96mm pattern on the bottom.

    Fusion360 simulation on a Speedio?

    Anyone succeeded in getting the new whole-machine simulation method to work? I've been playing around with it, but with limited success.

    Orange vs Schunk 3-axis vises?

    I couldn't sleep the other night and I was looking through the Schunk catalog at their KSC vises. I'm really happy with my Gen4 Orange vises, but I'm curious if anyone has run the Schunks and has first-hand knowledge of how they compare? I like the low-profile reversible jaws and fully...

    Form tapping M12 in 4140PH?

    Before I do something super dumb: I need to tap M12x1.75 through a 40mm thick 4140PH ground plate on a 16K Speedio. Haven't worked much with 4140, and the part has a fair bit of time into it, so I'd appreciate a quick sanity check. My plan is to spot, drill to 11.2 mm with a carbide CTS drill...

    Threads in fixtures?

    I’m working up some semi-permanent fixture plates for rotaries and similar. My plan was to make them out of 2” thick 7075, hard anodized. I am looking for some advice about the best way to hold down things to the fixture plates. I think I am overthinking it. My first idea was to just spot...

    Air blast during probing: yea or nay?

    I was running a bunch of Delrin the other day and the long, stringy chips made quite a mess around my probe and tool setter. Made me wonder: any disadvantages to running the air blast during the entire tool touch-off and probing cycles? It's pretty obvious how to modify the canned touch-off...

    Form tap trouble in 316?

    I ran into a weird problem tapping 316 and I'm kinda scratching my head. The part in question is made in two operations: the top, where I hit five surfaces, and the bottom, where I surface the bottom (it's at an angle to the top). The top has 2 M3x0.5 blind holes. The part mates to three...

    A curious case of exploding end mills

    I had an expensive day today and I am trying to figure out why. This 6061-T6 part has a number of 0.196" wide slots, either 1.417" or 3.346" long, 0.127" deep. Roughed them out with a ramp down at 2 degrees to full depth, leaving 0.005" per side for a finish pass later on. I was using Helical...

    Holding a plate with a big pocket?

    I am trying to figure out the best way to approach holding a plate with a giant pocket. The part is 316, 16" by 8" by 0.650", starting with 0.100" over size plate stock. There are four M8 tapped through holes in the corners. One-off part. My original plan was to use Talon Grips across two...

    Speedio file copy error?

    I ran into something really weird on my Speedio trying to copy files around. Before I really lose myself in the manuals trying to figure it out.... I have a program on a USB stick, named O1234.NC. Insert USB stick, file is visible and all that. Press EDIT, External Program I/O, key in 1234...

    DMG Mori ALX?

    Anyone have one, or seen one in the flesh? Thoughts, opinions? My parts fit in the work envelope and it's awfully compact for what you get -- I'd be looking at the simple 2-axis configuration. Looks great on paper but Mori stuff usually does....

    Practical experience: ESPRIT vs NX CAM?

    Looking for some practical perspectives here as I abandon Autodesk. I'm pretty much settled on SolidEdge for CAD. That leaves me with a couple of choices on the CAM side. Right now, I need 3+1-axis milling. I will probably need true 4th axis (well, wrapped paths would be sufficient) and am...

    NX vs ESPRIT: VAR recommendations?

    Sorry if this is a stupid question. I've about had it with Fusion360. Mostly 3D 3 and 4-axis milling, good in-process probing support, probably need turning in a year or two. So it sounds like time to set up some demos/trials of ESPRIT and NX. Sounds like those are two of my best options...

    Toolholder for deep pocketing?

    I sometimes need to finish a fairly deep (2-3") pocket in aluminum. I have been trying to use a reduced neck end mill (Helical 46361) for this -- it's a 0.500" dia, 0.625" LOC, 3.375" 3-flute. The toolpath is a simple circular pocket. Speeds & feeds are 0.500-0.625" DOC, 0.020" stepover, 1700...

    Fusion360 wrapped single-line sketch

    I have been beating my head against this for a while. I have a regular polygon with radiused corners extruded into a solid. I want to have an engraving toolpath that wraps around the part. I cannot for the life of me figure out how to get F360 to do it. I tried making a 0.01mm break in the...

    Speedio coolant tank best practices

    So the perforated mesh panel above the coolant tank is getting to be quite a mess. Chips get wedged on-end in the perforations and it makes cleaning the chips out pretty unpleasant. Any tips for how to get the impacted chips out of there? After I get it straightened out, thoughts on putting...

    MST 2-part toolholders?

    I'm thinking about trying some of the MST "2 piece" toolholders -- the kind where shrink-fit collets are pulled into a master holder via a draw bolt. Anyone tried them? The other MST toolholders look great for slim-nose applications generally but the 2-piece ones seem to be the only ones that...

    Coolant flow into tight pockets

    I have been cutting some pockets with a high ratio of depth:area, like 1.5" square by 0.950" deep. I have been doing these with a 3/8" 1" LOC end mill in either a sidelock or short gage length collet chuck; just helixing down and then blowing out the pocket. Done this way, it is proving...

    Milling C630 nickel aluminum bronze?

    Any tips on this stuff? It looks pretty close to C955 on paper — so probably quite abrasive, wants really sharp carbide tooling and a pretty healthy cut? The part has two tapped holes, one M3 blind and one M4 through; form tap OK or is that asking for trouble?

    Saw for a tiny shop?

    I used to just order stock pre-cut to size. But the Speedio is so fast :eek: that it has become glaringly obvious I need to bring in lengths of bar stock and cut them to length as needed. My overriding limitation is space. The closer I stick to 2 ft square the better off I am. As much as I'd...
