Yes in fact if you try to drill that without coolant it will eat up your tooling, it is very abrasive and you need to flush to chips out of the holes and keep the tools cool. I have milled and...

Dave most new CNC machines do not use dovetails they use boxways or linear bearings, that said the box ways do have oil passages on all sides so yes it would be a good idea to groove the dovetail...

OK I was assuming we all knew which holders were the right holders to use, tool pull out is an amateur error so I guess I made the wrong assumption about this place. I did not realize most of these...

Sorry but a larger cutter will almost always allow a faster feed rate due to the strength of the cutter alone. Only on a very few special circumstances will the smaller cutter be the better choice...

As a general rule always use the largest cutter possible this way you remove more material with fewer passes however there are a lot of variables involved here. How rigid the setup is ,does the...

Sounds like you could have an overheating issue in the control, open the cases check to see that the fans are running. Put a fan on the control and let it run with the door open see if the problem...

CCracer I think you are way off the beam on your ideas on the 5 axis machine. I do not own one but I sure know the value they can create. The 5 axis machine is capable of making parts for much less...

It is not an attitude thing it is a cost thing, I am not sure who you have been dealing with but I opened my company 28 years ago and I have never run into anything like that. Also it makes no sense...

Tburizo if you have the equipment that is right for the job and equal to the competition then of course it is always going to be cheaper to do it yourself. Those of us with shops are not doing this...

For under 1k forget it that machine does not exist, these low budget 3-D printers are aimed at the hobby level user they are not very accurate and they are also slow. There are currently several...

There are several raster to vector conversion programs out there that work pretty good. There is always going to be some manual clean up but the bulk of it will come out OK. The original image needs...

Patric patent laws can be tricky, its possible that a device like that used say for example on a specific piece of machinery is covered by a patent. It is possible the actual method it uses is...

I was not trying to be negative in any way just trying to save you some possible problems and money. I have been involved with the patent process many times over the years so I know what is involved...

Patrick great idea but I hope you did some research before you gave a lawyer any money for 2 reasons , one I think I have seen a similar device on the market already two it is unlikely you will be...

I just looked at your webpage I think you need someone with a better understanding of the English language it is almost unreadable. That gives me little confidence you would even be able to...

Not surprising to hear of the quality issues, it is very common to get garbage from China. The thing is they know full well it is not worth the money it would cost to ship the stuff back so they ship...

Yes Kapton tape is good for 7000 vac and good to +300f I have used it as an insulator before. It is also thermally conductive so if your bare aluminum happens to be a heat sink so much the better.

Slick27 is right should have clarified that it depends on the design of the machine. The spindle on my machining centers has a round housing around it the spindle itself rotates in that housing and...

It does not have to be China it could be any country I was just using them as an example because they happen to be the current country most exploited by the large corporations. If you will go back...

Well I assume you do not have the bracket that came with the machine when it shipped so you have a few options. If it is only 20 miles put a piece of wood on the table thick enough to bring the...

With the economy the way it is now anything you write up would only be a guess and if you are in the USA and attempting to compete with countries like China you may as well forget it unless you...

Yes you can climb cut with any tool some will work better than others it really depends on a lot of factors. How rigid your machine is, how much backlash you have in the screws, how well your part is...

If you have backlash in your system I do not reccomend you try climb cutting, climb cutting pulls on the entire spindle assembly and if there is backlash you will get poor results. You must have a...

We have machined aluminum parts using a vacuum table it is something you can easily build and as long as your parts have enough surface area they will hold in place easily. With this you do not have...

Yea I remember the days of punched paper tape, things have certainly come a long way. I also remember the time sharing on the computer systems for programming crazy expensive and not even close to...

Mike I know Gibbs is not cheap but it is a matter of what you save in the long run. I use it because I do this for a living I need to make a profit. Anyone working on home projects would find the...

I have to dis agree with metal cutter, Virtual Gibbs although not free is very simple to use right out of the box, many of the newer CAM programs are. As far as programming that depends all on your...

The wider the spacing the more rigid the setup will be, there is no set ratio as it depends on how accurate you can get the fit to be. Too tight it will bind up too loose and you will have an...

Well there is no "hardened aluminum" you can get it hardcoat anodized but it will not last very long with steel v groove followers which I assume is what you mean running over it. One small nick and...

Sounds like you are not talking about large jobs here so It is not unexpected that you will not get the service you should get. I would say the best option is to find a smaller shop to whom that...
