    Please help me identify this 8" vise

    I picked this up for free with the intention to restore and use it. Well, the tag on the side is gone, there are no other markings, and it doesn't match the other known good 8" Kurts we have here at the shop (hex on the leadscrew is smaller, threaded holes in the jaws are 3/8" and not 5/8"). I...

    4020 grinding while spinning up in high gear

    I'm having a problem with our 4020 whereby it seems to shift into high gear smoothly, but upon acceleration, will grind getting up to speed from zero. This is most noticeable in the spindle warmup program I run, between the 2500 RPM and 5000 RPM. I have tried programming a short dwell, and a...

    Fadal Format 2 operator load/unload position

    I am trying to figure out end-of-program lines of code to send the table to the door. I'm in Format 2 and do not have any SETH, SETX, or SETY defined. My E offset is always from the cold start position. I'd like it to be so that no matter where I'm set up on the table (vise in the center, vise...

    Fadal 4020 backlash and interpolation

    I have a job on our Fadal 4020 that is a series of blind .7500" holes, .875" deep. I've programmed them in Mastercam using the Helix Bore toolpath. 2000rpm, 35ipm. Inspecting the hole with an indicator and Indicol, the machine is cutting it round, but at the 2:00 and 8:00 positions, there is a...

    Fadal 88HS choppy motion

    Today is my first attempt making chips on our 4020 after the last guy left 4 months ago. It's been simple stuff so far; linear moves with lead-in/lead-out and a pocket with helix entry. In both cases, the machine is not looking ahead hardly at all. Lead-in, stop, G1 move, stop, lead-out. Or on...

    Fadal 88HS operator position page

    Hello there. I have a 4020 with the 88HS control. I set all my work offsets with an indicator attached to the spindle. It's always nice to get close, zero X and Y, and then dial it in from there. Or zero on one side of the hole and drive to the other side. Is there a page in this control...

    Spindle warmup programs

    We bought two new Haas Mini Mills; a 6,000 RPM here in the toolroom and a 10,000 RPM in the CNC department. They came with a spindle warmup program that had the instruction to "set spindle override to 50% for 5,000 RPM machines, 100% for 7,500 and 10,000 RPM machines and 150% for 15,000 RPM...

    Fadal 88HS running a program

    Good afternoon. I am trying to get our Fadal VMC 4020 up and running again after the last guy left. It has the 88HS control with a USB drive on it. I have a very simple test program to experiment with tool offsets and such. What I'm struggling with is this; if I exit the program to adjust cutter...

    Any suggestions for helix boring hardened A2?

    I have a part made of hard A2 with an array of 50 1/4" dowel holes, .250 deep. It's a fixture. The holes have been roughed out to .240". Jig grinding is not an option due to the cost. Wire EDM is not an option due to the holes also having 10-32 threads in the bottom. If I were to helix bore...

    Editing post for specific G53 at end of program

    Hello there. I have a Haas MiniMill 2 and MasterCAM 2021 and the "Generic Haas 3X Mill" post. I would like to edit the post so that every program ends with the vice in front of the doors (X-10, Y0, Z0). I don't want to have to do this for every program. Could someone point me to the line that...

    Problem cutting spherical radius with Surface Finish Flowline

    This is a feature that I'm trying to program. It's .500" spherical radius. I'm on a 2-axis seat of Mastercam 2021, and programming from the solid model. The face of the radius is the drive surface. I can get through the flowline parameters and see the toolpath. However, when I go to backplot...

    Setting up multiple WCS on one part

    I've posted a couple of beginner questions recently. Thanks to those who have helped me learn. I really appreciate it. I have a 2-axis seat of Mastercam 2021 and a Haas MiniMill 2 here in the toolroom. I've been on this arrangement for about 2 months. Both of these are a serious step up from...

    Custom drill cycle: initial peck, full retract

    I have Mastercam 2017 and a Haas Mini Mill 2 here in the toolroom. I've just gotten started on the Haas about two months ago, pushing through as much 2.5D work as I can (no 3D seat yet, at least for me). I've run into a certain job where let's say I need to drill a hole 4" deep. I start with a...

    Assistance with 2D programming this 3D part.

    I've been on a Haas Minimill 2 and a 2D seat of Mastercam 2017 here at work for about a month. I have experience with Mastercam X5 and my Sharp 2-axis mill. I'm on my own for figuring out the programming of the Haas. This is what I'm working on. It's a sprue bushing, part of an injection mold...

    Haas MiniMill 2 unloading tools

    We just got a MiniMill for the toolroom. It's going to be programmed with Mastercam 2017. I have Mastercam experience, but my G-code is rusty. I get that Tx M06 changes tools, but how do I drop off a tool and not pick up another one? T0 M06 doesn't work on the Haas control like it did on the...

    Mastercam X5: programming rapid moves between chains

    I hope this is the right forum. Please move the thread if not. I have Mastercam X5 and a Sharp mill with Prototrak MX2 retrofit here at work. I program it from drawings in Mastercam. Is there a way to program rapid moves from one chain to another in Mastercam? Say I've got the quill at a...

    I crashed my grinder. What now?

    There is a certain MHT surface grinder at work that I use regularly. There are almost enough grinders for each toolmaker to have his own. One day, I had one of those pink 150L wheels on and had the wheel way too low and ran it smack into the corner of my part. The spindle stalled and started...

    Learning 3D MasterCAM on my own

    I work for a small mold shop. Recently, our CNC guy turned in his notice and left rather quickly. The shop moved one of our toolroom guys into the CNC position and he has been learning from the old CNC guy for about a week or so. The management also told me that I will be the "backup CNC...

    Making a one-legged depth mic.

    At my work, I have some use for what I would call a one-legged depth mic. I have a secondhand mic from a local guy and want to modify it. What is a good, safe way to do this, as far as not affecting the metal body of the mic, heat treat or otherwise? Cutoff wheel, surface grinder, electrode...

    Pocketing mold base on Prototrak.

    I have a small mold base that I am pocketing. Material is #3 steel/P20, depth .940, 1.500 wide, 2.500 long. There are three "legs" off the main pocket that are .875 wide. I was going in there with a .597 carbide 4-flute endmill .500 deep at a time, 1000rpm, 4ipm and not only was it taking...
