wobbling problems

Hello!

I've been building a CNC router for a while (gantry type, stationaty table), and got it ready enough to run some wood routing this summer (worked like a charm!)

Now I've been thinking about milling som aluminium, spent yesterday evening with some cad/cam and tried today: catastrophy.

It cut downward in a spiral to get to the right depth, started to spiral outwards and then it went crazy, wobbling all around the place.

I'm new to milling/routing so the basics on feedrates and spindle speeds come from sporadic googling, not a solid education.

I am pretty sure this is a major construction issue, that the gantry is to weak and give room for some movement.

However, I now ask you if there could be anything I can improve without rebuilding the entire machine.

Lubricant, feedrate, spindle speed, type of tool, climbing cutting or not.

Hope you have som constructive opinions!

Problem TL2 Haas Lathe

Im new to eveything cnc, we have a TL2 Haas which I have just started to learn how to use. I have an Alarm error on tool position 1. Tool post looks mechanically down and a reset clears the alarm, tool position 2,3,4 have no errors in locating in either fwd or reverse rotation. The air wasnt up to pressure on homing tool1 and it did make a bit of a noise at the time. There seems to be no visable mechanical issues. Has anyone any experience of this? are there any limit switches in this unit?
Any help would be greatly appreciated.

Art Project Panels - Corner help

Hi!
My background is in art not sheet metal so im hoping someone out there has the solution to this...

I am ideally trying to create panels out of 2mm ali with mitered corners and 1in flanges bent to 135 degrees - to eventually send to a cnc bending fabricator.
- Are the following corners possible to fabricate (see red blue example)? I know drawing it in CAD is one thing...
- or do i have to off set one of the bends (like in the green example.)

cheers for any advice you might have!!

PUMA SM Thyristor controller to Breakout board connection

Hello,
I am new to this and learning as I go. I have retrofitted an older D&M 4 CNC lathe that was designed for a classroom learning environment. I have everything working with a breakout board except the PUMA SM spindle controller. The controller is still connected to the original controls of the lathe using pins 1, 3 and 4 but I am not sure what type of input they are supplying. The goal is to have Mach 3 Turn control the spindle speed.
I was wondering if anyone could explain how I can connect the breakout board to the controller using the 0-10V output or the PWM output from the BB. My concerns are what physical connections are needed between the boards and what jumper settings are needed on the controller board? Also do I need to connect anything to the torque control input?
Attached is the documentation for the BB and the PUMA SM Thyristor controller.
If anyone has any advice I would appreciate it.
Thanks for looking.

manual quill for M-15 Centroid knee mill retro.

October 29, 2017, 8:48 pm

I have a Vectrax MSC Centroid M-15 knee mill that I would like to modify the quill to function as the X & Y axis in "free" mode. I realize the only way to make that hapen is to replace the rotary encoder with a 6" glass scale. Tha z axis kit is an early Elrod design, and by drilling a 1/4" access hole that lines up with the ball nut housing clamp screw when at the bottom of travel, I can free the nut from the clamp housing and have a freed quill. With the glass scale reader head attached to the clamp housing I should "theoretically" have a manual Z dro like the X & Y if there is a way to go into setup and activate a Z axis free command. Is this possible?

Thanks for any help,

Woody

Hello, I`m a proud owner of a MAHO 600E with philips 432 cnc.
I intend to upgrade it to MACH 3/4 using the indramat drivers (+/-10v), KFLOP+KANALOG and heidenheim linear scales.
My first problem is the heidenheim scales, wich are Sin/cos type.... what comverter do you recomand to covert the to TTL or someting that will work with Kflop.

Mineral (geopolymer) Vs. Organic Polymer Expoxy For Granite Composite

I've been a lurker on and off for years. I debated posting this question because it relates to research that does not appear to be very well followed and quite frankly offers incredible opportunities. My work has been looking at them for advanced and technology integrated sustainable housing.

The precursor materials can be and form a gathered form local waste or geologic materials. They for three dimensional aluminosilicate nano ceramic binder that offers a cheap path to ceramic and ceramic metal matrix composites. The materials provide room temperature cured polymer structural refractory elements capable of 800c+. The nano composites can also be crushed and used to make silicon carbide and silicon nitride at around 1/2 the typical energy consumption.

It seems like something that people here would find interesting. I have been working with these composites for the last 6 months and have successfully synthesized sample compelling enough to verify the technology is the real deal. The jury has been in on these materials for a few years, but there is a very small following so far. Once you realize what they are capable of making, it becomes obvious that everyone is way underestimating the magnitude of disruptive change that is coming.

Here is a link to a US researcher's website. I have been in contact with her and believe she is likely the leading geopolymer researcher that is focusing on the technical ceramic end of the spectrum. Kriven Research Group - University of Illinois at Urbana-Champaign.

Hello, im graduate trainee and i have a question about Steam Turbine Vacuum system.

This is our vacuum interlocks
  • Jet Water Pump press : 5 - 6 bar
  • Vacuum Normal : (-0.86) - (-0.91) bar
  • Vacuum alarm water pump : <-0.75 bar
  • Turbin trip : -0.61 bar


What might make the vacuum system not work normally and cause a turbine trip?

Bridgeport series 1 interact 2

Hi, I'm looking at moving some of our cnc milling needs inhouse, I'm currently looking at purchasing a rather cheap Bridgeport interact for small production runs.
However, I can't find conclusive information that these machines will handle our files.
Most of the stuff we make consists of 20,000 lines of g code on 3 axis with lots of XY arcs. I'm used to just sending these files out to be made on newish HAAS. However for use on these machines I understand we are required to convert this g code to conversational code, which is easy apparently.
But then this is where I get confused, assuming the Bridgeport is setup toolwise, once the file is converted and loaded onto the machine via serial cable, will the Bridgeport be able to accept the file without issues? I struggle to understand that a 20+ year only machine will cope, but I'm happy to be wrong.
