    Fadals are NOTORIOUS about shattered belville washers.

    I broke 3 brand new Destiny 5/32" stubs in a row slotting .07" deep @ 35 ipm 6k spindle, doing a part I had made many times before with those tools. Fell back to the old 2 fluter backup and no...

    Knowing what your application is I suggest Harvey #61812-C8, it is a 3/16" x .285 loc with .005" corner radius TiB2 coating. This is one of the tools I never take out of the carousel. I am using...

    I use 1 or 5 micron 7"x32" bag filters from McMaster-Carr, sewn seam trade size 2. They cost $7.90 and last for 3 months. The heads are around $20. I will never go back to unfiltered coolant. No...

    When I bought those 3 years ago I found out they are defective, the 3/16" mill photo is NOT of a 3/16" mill. The scallops are too big/deep so the cores are tiny making them very fragile. Garr makes...

    Contact Leadwell or their local-ish distributor to get it. If an email doesn't work then try by phone, or phone first. They will want the serial # of the machine.

    PVC is quite similar to ABS, perhaps a tad softer. Both are fairly abrasive to machine so your HSS will lose its sharpness quickly. On an ABS production job I ran a 3/4" carbide mill at 3k and...

    How good is your relationship with them? Maybe talk with them about this.

    Online, and if you have time put your stuff in a cart, save it, and wait a few days. There is a good chance you will get a discount coupon.

    So there are no such things as toolmakers, just good machinists?

    I just looked around some and didn't find better prices than direct, but I didn't look very hard. What voltage will you need? I got my buck transformer from PP when I got the converter.

    What the machinist thought was a tight tolerance was way off of making a useable part. To be honest I don't see some clear distinction between toolmaker and machinist, I think there is a lot of grey...

    I consider myself a toolmaker since my first 8 years of machining was doing form tools, jigs, fixtures, and mostly plastic injection molds all on manual machines. Anyway, while at my second...

    Employer was too cheap so I had to lower the max spindle speeds from 10k to 8k, then 6k by the time I jumped ship. I also was modifying programs to get rid of the swirl marks in pocket floors as...

    25,000 hrs grease, double that for air/oil. And 20 years on a Fadal spindle means it didn't run much. The one I worked with got 6 years of one or two shifts a day from new. That is before it died,...

    It has some big heat sinks with fans so it looks like it. Enough that you can't put it in a small room or box without ventilation. The small ones only draw 80 watts or so so it can't be too much...

    I will second putting even the PP outside of my shop. Sure it's not as noisy as the vmc but it adds to the total noise so out it goes. Cooler in the summer too. One mill makes enough heat to keep...

    I have no idea what you are talking about. I have used them for over 20 years now and even the 1984 model could mill fine with 1/2" end mills. Shit, even the 1978 robos could mill fine with 1/2"...

    What manuals are you getting with the machine? No schematics manual is a real :eek::eek::eek: if you ever need it. What about parameter backup? When were the memory batteries last replaced?

    MariTool has what looks to be the same. Lyndex makes an ER20 holder that is flush with the flange, but the nut is proud .3". Other than the Lyndex tool mentioned MariTool is the place to go for...

    How about foaming agent? That would reduce the tonnage by several factors, and material cost, and cycle time. Although I wonder how you would protect the plastic from UV? Or maybe that is just...

    No idea about a master inspection list. Listen to how everything sounds at full speed, especially the spindle, and listen to it change tools trying to hear any misalignment. Being an old lighter...

    After buying a few used mills now I would be very leery of the cheaper machine, a little more $$$$ for a machine in better condition is way cheaper than trying to repair the cheaper machine. Even...

    Plugging holes takes time too. And certainly digging media out takes a lot of time.

    Why can't you use media that is too big to get in the holes? That is what I have always done.
