    Mist Collector for Brothers

    Hi Everyone, We have four Speedios that often poof out a cloud of mist upon opening the door, so I am looking at mist collectors. Yamazen suggested either an Amino MZ-15 or MJ-10. They said the cost is about the same for both but the MJ-10 is filterless. Does anyone have any recommendations...

    Replaceable Milling Cutter Heads vs. Inserts Recommendation

    Hello Everyone, We keep a 2-insert 1/2" end mill cutter in our Swiss lathes for cross milling. We only cut steel. They work really well BUT the teensy tiny T6 screws are a pain to work with...easy to strip out and easy to loose unless we want to take the cutter body out every time they need...

    Warping While Trying to Mill Down 6' Bars

    Hi Everyone! Our usual 1-1/2" X 5/8" CF ANN 4140 is not available so we are trying to cut 1/8" off of 1-1/2" X 3/4". We set up three vices in a row on a Haas TM-1 with deadman's on each end to help with vibration but man-oh-man are they warping after taking off that 1/8"...convex on the side...

    Understanding Lathe/Mill Cutter Comp Startup Moves

    Hi Everyone! I have a few questions about cutter comp I am hoping y'all could help with (especially #3): 1) It is my understanding that when invoking cutter comp on a mill, the G41/G42 line must include either a G00 or G01 move of at least the radius of the tool in either, X, Y, or X AND Y...

    OT: Clear Coating Over Oil-Based Paint

    Hi Everyone! I made a thing out of brass, engraved letters .015" deep, painted it with oil-based paint, then faced the surface the letters are on. It looks awesome since the surface is a nice shiny brass with perfect paint-filled letters. I spray lacquered the whole thing in an attempt to...

    Poor Insert Life in 4340

    Hello Everyone, I suspect I am getting poor insert life but wanted to run it by y'all as a reality check as well as ask for any help you can offer. The picture shows what all four sides of the insert looks like. One thing I can say is an axial groove is milled into the side of the part and...

    Help! 2002 Haas TM-1 Not Powering Up

    Hi Everyone! We recently had the monitor replaced on our 2002 TM1 and it was working fine until two days ago we left it on over night and the next morning it was off. No one said they turned it off so we think it went off on its own. When pressing the “On” button on the controller you hear...

    How Does Your Shop Keep Track of Employee Productivity?

    Hi Everyone! So just like the title says...do the supervisors record number of widgets made each day and put it in a spreadsheet, look at "cycle start time" on machines, etc??? Are there periodic (i.e. daily, weekly, quarterly, etc.) incentives for meeting the goal as an individual and then...

    Tube Chamfering Machine You Like?

    Hi Everyone! I am looking for a machine with a hopper to load saw-cut steel tubes (1/2" OD min - 1-1/4" OD max and 4" long - 24" long) into that will load, chamfer the OD and ID as well as face the tubes to length, spit them out, and repeat. I do not think brushes will "cut it" so I am looking...

    How to Sell an Old Auto Saw?

    Hi Everyone! We have this old (1940's) power hack saw with auto feed and (not shown) a nice long bed with rollers. It is old but built like a tank. The auto feed works but is a little inconsistent....maybe +/- .050" worst case. Anyways, I keep responding to those, "We buy used equipment!"...

    Tool Length Help with Brother TC-S2A-O A00 Control

    Hi Everyone! I have an old Brother that was set up "improperly" IMO that I am trying to set straight. All the tool lengths are like 14" long in the offset registers and the G10 at the top of the programs are like Z-6". The "Auto T/L Offset" parameter in switch 1 was 0". Here is what I...

Please see the attached exercise attempting to show a technique for describing a finite state machine with two states (on and off) controlled by two switches (S1 and S2), using that graphical depiction to generate a boolean expression for the conditions resulting in those two states, and...

    Do Turning Tool Holders for Negative Inserts on Swiss Machines Exist?

    Hi Everyone! I have contacted several distributors and a couple major brands and no one seems to make a 16mm/.625" solid stick tool for a neutral, say, CNMG insert for a Swiss-style lathe, where the shank needs to be in-line with the tool nose. There are plenty for positive inserts, like CCMT...

    Where There's Smoke Is There About to be a Fire? (Swiss Turning...)

    For whatever reason I have not had much smoke in my Swiss turning ops...mostly annealed low carbon/low alloy stuff like 1020, 4140, 8620, etc. I am NOW turning 1-1/2 PH 4140 (~30HRC) and it looks like a smoke bomb is lit on my turning tool. (Mitsubishi CNMG 800SFM per their recommendation.)...

    Speedio Invalid Data Alarm Help

    Hi Everyone, I keep getting an SM4006 invalid data alarm while trying to make an X move on line 1657 on my Speedio. I tried single blocking it and it DOES make the G2 move on the line before but it never even starts to execute block 1657. (See the POS screen that says we are still in G2?) I...

    Brother Speedio Spindle Rattle

    Hi Everyone, Our newest S700 High-Torque Speedio (less than two years old) all of a sudden started making a rattling/tapping noise reminiscent of baseball cards in bicycle wheel spokes. The faster the spindle rotated the louder the noise would get. I tried rotating the spindle by hand and it...

    Milling Marks from Wiper Inserts on 4140 Skim Cut

    Hi Everyone, I am skimming off .005" from a block of annealed 4140 with a nice Ingersoll face mill using wiper inserts @ 700SFM and .020ipt and getting some swirl marks. The attached picture does not quite show it, but there ARE swirls going both directions, so I do NOT think it is the...

    Funuc 18T Backlight

    Hi Everyone, After 30 some odd years the screens on our Hardinge Conquests are getting a bit dim (okay, it actually doesn't look that bad in the pic.) Both Hardinge and Fanuc were not helpful. Does anyone know where I could get replacement backlights for the LCD screens? Thank you!

    Brother Corner Radius Programming

    Hello Everyone! I've been using IJ for corners and want to learn how to use R/C for my Brothers. I am having trouble interpreting the NC Manual explanation and there aren't any programming examples. Do you just add the R word at the end of your line, like this for a square with 10 unit long...
