I the past I used this machine a lot more than now. And then I did look into buying a new one. These machines new tooled up are very expensive. One this size would be in the neighborhood of $600.000 dollars. So at this time I would not buy another one if this one died. If I was younger this is my thought about buying machines for busness/making a living. I would always buy new if the busness plan could justify it. Because you have to depend on the machine working consistently. So to have a warranty and quick service is paramount. Also you have the latest technology to be competitive in industry. All my machines I currently own (except for the ones in the garage) I purchased used. They are all around 20 years old. So if something goes wrong it could take time to repair. But at this time in my life I could afford this time. But if you are running a busness with employees. Your most expensive cost is labor. So the new machine is the best route. I don’t know in your country but in the USA there can be certain tax advantages to offset the extra expense of the newer machine. Kind of a long response but this is a rather quick answer to what can be a complicated decision. Depending on the busness situation.

@ Edge ?. Beautiful response. At that price for a new machine you would have to have a lot of work for it to be worth the investment.

@@EdgePrecision Thank you for the answer - makes a lot of sense.

Yes Star kind of specializes in grinders to make and sharpen gear cutters and hobbs.

Look up anca fx7 or Walter hmc 600. Have fun.

Add to that I had no idea how the carbide blanks were made

The sphere/ball under the probe on the spindle is for calibrating the grinding wheel probe. The square block above the collet chuck is for the tool probe on the spindle. I wasn't to clear about that in the video. As for the computer. The machines control is actually in the back cabinet. Star grinder make new grinders. Also using NumRoto software. I'm pretty sure they are running a newer version of windows on them. They probably could setup a whole new computer to run this machine. But I would be a little costly having to upgrade the software to the newest versions. That's where the cost would be.

If you want to organize something than you have to have three piles a keep throw away and maybe keep. After that put duplicate tools in same place as each other and don't forget to put them away which will make you lose them and have to buy more which isn't good or if you are only one working at the time keep a logbook of what tools you got out of the tool room. Like my teacher said if you have a clean organized tool room you should be able to tell someone exactly were a tool is.

I didn't show this in the video. But I indicated the drills to less then .001" of indicated run out before grinding. It can be done by lightly tapping on the end of the drill with something soft. Like a piece of brass or aluminum. The probing has no effect on the run out.

I have other videos on my channel about using this grinder.

I'm not sure what that is. And why it would work. The even if the window was clear there is so much coolant you cant really see the tool anyway.

Yes that is possible up to the shank. But this machine isn’t really setup for cylindrical grinding. I would regrind the flutes with a slight clearance angle. That’s what I usually do when making special size drills.

No it is special just for this purpose. The first oil I used in this machine was called Carbogrind it was thin just like water. It was an excellent grinding oil. But I was very sensitive to it. It would give me a rash like poison ivy. I had to change to this oil. It is made by Hanksterfers. But I think they no longer make it.

@@EdgePrecision interesting. I only learned about the world of CNC as a decade ago I was a traveling salesman selling industrial chemicals (mostly cleaners) and our company bought a cnc coolant company and they wanted us to start selling there stuff that they claimed was less likely to cause contact dermatitis. So I spent a lot of time in machine shops talking to guys that get dermatitis from their coolants and I was surprised how big of issue It really is

This is a very difficult audio situation. There are many machines running all around me. Not to mention the one I’m running. Air grinders, people blowing air guns. I’m filming in a working machine shop. I have tried to put filters on the sound to reduce this noise. Then people complain about the sound as well. Because it distorts it in another way. I get even more complaints.

@@EdgePrecision i completely understand your situation. It was an audio jump at like 17 seconds in... either way, wasn't trying to be a buster about it, it was just that one clip right off the bat that made my headphones jolt me a little. I am a content creator, just on a different account for a hobby, but I think most programs can show your audio levels so you can see those big variances between clips like that. I enjoy your footage though.

And to be clear, it wasn't background machine noise or shop noise, it was voice audio from one clip to the next. Id be a fool to complain about background machine noise on a machine video.

This machine has Marposs probes.

@@EdgePrecision I been grinding braze carbide tools manually..this machine is amazing

Are you referring to under machine bases?

@@EdgePrecision Yes,I heard it keeps it from tapering

@@lonestar9453 yes a foundation gives more weight and stability, rigidity to the machine. Although they are not usually that thick. The one under my Mazak is around two feet thick. Under the Mitsubishi horizontal mill about three feet. This grinder in this video did not require a foundation. Because of the way the machine is built.
