    Weight of Kearney and Trecker 10HP-2CK horizontal mill

    Thank you very much for the good information. The machine I was looking at has very little information regarding its operating condition and would be "as is where is" based on the dozen pictures provided... so potentially four tons of scrap to road trip home. I let this one go, and will look...

    Weight of Kearney and Trecker 10HP-2CK horizontal mill

    I have a K & T 3B plain that is supposed to go 6600# and feels like it. It is plenty heavy and bulky, and a I had wanted something a bit smaller as shop space is precious. Saw a 10HP-2CK and figured I would bid on it as it would be smaller than the old 3B and more modern (than 1915). Found a...

    1995 Fadal VMC rotary broach G-code

    I use Solidworks 2017 with HSMWorks 2020. I find some of the drill canned programs to be routinely ignored. For example a partial retract just bores right through without any pecking at all. I believe I am using the post for generic fadal that comes with the CAM, but to be honest my son helped...

    1995 Fadal VMC rotary broach G-code

    Thanks for the help. Yes this machine has an encoder and will rigid tap. It is exactly the polygon heavy duty broaching holder with their brake. I will have to run some tests, but it appears on stop command the spindle ramps down rpm and stops at a random location. When tool change is called it...

    1995 Fadal VMC rotary broach G-code

    Hey folks, need a tech assist in getting some code set up for an indexed rotary broaching process on my VMC. I added a sample of a simple broaching cycle from a non-indexed broaching program I already use below. I have an inside spline broach that needs to index on features that have been...

    Haas SL-20 static tool alignment

    Yes OD tooling. As you mentioned, there is a pin that locks rotation of the tool holder so that the groove is always perpendicular to tangent of turret. Is it as simple as the 1" shank height tool holder is just designed so that the cutting height of the insert lands in the right place? With...

    Haas SL-20 static tool alignment

    Hi - I bought a 2000 Haas SL-20. I have some work to do in the shop before I can place the machine in position so thought I would learn all I could from the manuals and available videos so I am ready to go when I can finally unpack the machine. I have a Fadal VMC, so understand the basics but...

    Pipe thread taper wrong direction HSM works

    In researching the lathe manual I have found the necessary gcode to create tapered threads. It is an "I" command following the G76... not completely sure of the proper syntax, but at least there is a way to get the machine to do what I want even if the CAM software won't do it for me... its just...

    Pipe thread taper wrong direction HSM works

    I am using Solidworks / HSMworks and trying to make a double male adapter that is hex in the center. The end toward tailstock is JIC male #3, and the end toward the chuck is 1/4 NPT male. In simulation I have faced the end, bored the center, and turned the JIC male end without issue in cam. I...

    Haas SL-20T opinions...

    How hard is it to resquare the machine if that was needed? It is not a local machine that I can evaluate first hand. Thanks

    Haas SL-20T opinions...

    Hi Folks, I may have the opportunity to purchase a 2002 Haas SL-20T. It has live tooling supported for all ten turret slots and a couple of live tools included as well as a few insert holders. It includes the chip auger, parts catcher, tool setter and 300 bar feeder. Please chime in with...

    What (old) CNC lathe to buy as a starter

    I spotted that Okuma LC20 earlier when searching, and its reasonably close to home. Was surprised by the weight. I have access to a proper trailer, but even if they could load it I am not sure I could get it unloaded at my place... Rough terrain forklift in the #15k load range can be rented here...

    What (old) CNC lathe to buy as a starter

    This job was only turned parts. Six different parts in stainless in quantities of 2-20 units with some complex curved features. All parts less than inch diameter and up to 12" long. Customer 800 miles away needed the parts in five days and he was providing the material. He already had a...

    What (old) CNC lathe to buy as a starter

    Hi, I have a small fabrication and machine shop, and have had to turn away recent jobs at the shop that need even modest quantities of a turned part due to the inefficiency of manually making each one. I have gotten my toes wet successfully with an Arclight Dynamics CNC plasma table and an old...

    American Tool Works Lathe

    I checked the spindle and it turned smoothly without much drag. I rechecked the belt tension and the tightening mechanism was bound up... the resistance I felt was not the belt getting tight. Repairs made and belt now snug. I was able to successfully cut a Brown and Sharpe #12 taper on an arbor...

    American Tool Works Lathe

    Made the piece for the taper attachment as suggested by Clive603 above (bolts to be replaced by set screws once I get to town). Seems to be working perfectly... which brings up the next problem. The flat belt is slipping on all but the lightest cuts (tightening did not appreciably improve the...

    That sounds simple enough to make, and presents a very practical approach. Thanks for the suggestion!

    American Tool Works Lathe

    Have gotten a tapered gib made for the piece that attaches to the cross slide and it is in place and working smoothly. The last piece of the puzzle is the missing sliding block for the taper way. The taper way is square sided rather than a dovetail. I need some guidance on design... would it...

    American Tool Works Lathe

    It is number 35496, so it might be even older than my 3B plain K&T horizontal from 1914 or 1915... it was 4 of lot 453 when lot 671 was 1920 as well. I seem to gravitate to machines of this era... Thanks for the great link to the information on this lathe. I seem to have another piece of...
