    Manufacturers recommended speeds and feeds seem way to fast

    sandvik 870 tip drills here in grey and ductile iron. ours ran 425 SFM and between .008-.018" IPR (1/2" drills normaly ran around .010"). grey always had a sequel and ductile was a more quiet squeal (if you could even call it that) with a smooth hiss. we used regular setscrew type endmill...

    Is it OK to use a Through Coolant Face Mill with a Flood Coolant system?

    Only problem i ever had was in a iron foundry machine shop. the guys never pulled, cleaned and then put them away after a job. The grey iron would get in the ports and set up like concrete. then when you put the tool in a TSC mill get everything touched off and are ready to go, Guess what, no...

    question about tool length compensation in manual program on Mazak VTC20B

    your using the manual mazatrol unit correct not EIA? If the former, it will auto comp for the tools length and SFM/rpm based on the data in the tool offset page on the machine control like any mazatrol unit(unless its a specific rpm is commanded in the manual unit) , and what ever diameter you...

    Possible machine overheating ???

    encoder? the 06 vf6-50 where i used to work had the set screw on the pulley attached to the spindle encoder back out ever so slightly to where it just wiggled back and forth on the shaft. spinning a drill/endmill one direction and you would never know it, go to tap and at the end of the tap...

    Threading M64x6 on QT15N

    93 sqt18ms in the shop i worked at ( a c axis), the encoder board on the spindle unit controlled the thread timing and c axis positioning. it started going out and would show only on the c axis when it would get hot but would thread just fine, our tech said it was a wonder it would still thread...

    Chlorinated vs Non-Chlorinated Soluble Cutting Oils - What's the Difference?

    my machine tool instructor talked with us about the old days with cutting/tapping fluid with trichloroethane, Like the original cool-tool (have a tube in an unopened package some where that he gave to me when he retired from teaching), he said on of the main health effects which he knew first...

    Looking for ideas to lubricate 660 bronze bushing.

    yes grease fitting on the yellow housing and also make a couple shallow grooves on the outside of the bronze bushing to hold grease. if you can make a multi start thread, a few shallow passes .015-.03 deep with a sharp point threading tool will work great. done this on the id of some brass...

    Haas Auger causes surface finish issues, anyone else?

    jack the machines up and set them on a 1" or thicker steel sheet thats bigger than the size of the machines base (bigger is better). not perfect but its a good workaround for thin concrete to help spread the load a little more evenly and reduce machine chatter plus it also helps lathes stay...

    Help with finish on SS

    look at a sandvik 345 face mill. 8 cutting edges per insert, it's good heavy insert with replaceable seats, and they make a wiper insert that replaces one of the 8 edge inserts for better finishes, letting you use a semi-roughing speed and depth of cut and still get a good finish

    XYZ EMill Keeps Cutting Out

    That white LRD you singled out in the first pic is a timed overload breaker. Think a regular circuit breaker on a timer, they are used for motors that can start instantly or with a load. example: my old air compressors single phase motor doesn't have a built in thermal overload and uses one...

    Threadmill tool type

    For say a 1/2" dia thread mill, I normally put it in on the mazatrol side as a .5C endmill with whatever dia it measured in the act.dia section.

    Thread gauges

    Starrett, Mitutoyo & B&S. Personally i like Starrett and Mitutoyo both make good pitch gauge sets as others have said. I once bought a cheapo set that had both metric and imperial. I noticed the imperial pitches were good but i had a few of the metric pitches were completely wrong (I compared...

    New Haas door safety

    Not always about cam showing "what its supposed to do", cause whose never had an instance where the posted pg has a error generated during the posting process that wouldn't be shown after the verify/simulation says its "good" (had it happen by a freak chance after a software update, but stopped...

    Disable that stupid door lock?

    If its like a 93 sqt18ms or a 96 qt30 with the roller arms, there should be 4-5 wires under the cover and you should only have to bridge 2 together to close the loop. I found which two they were and spliced a extra wire on each one (outside of the switch under the pannel), and then ran them to a...
