Make a few quick change knife holders, I think I found a better way!

[a smile]

My lathe is REIDEN-t200, using 125 quick change tool holder, only 3 tool holders when I bought the lathe, I need more, and then I tried to make some by myself, using the milling machine to make T slot, V slot, although very fast, but the accuracy of the production will have some defects, and beauty is also a problem.
After I began to learn to use EDM, I tried to cut the outer outline, which made me experience: easy processing, more styles can be made, and more practical.


I re-purchased some steel plates, the size is accurate 125*70*50, so that the outer size machining is omitted.











This is the lathe mounted tool holder, I carefully measured, recorded detailed data, and then used SW to complete the drawing

In 2021, two tool holders were made using a manual milling machine

Nice work!

After heat treatment

Very nice work. My lathe uses the Rapid Original tool holding system which appears to be pretty much identical to yours. I've contemplated making more tool holders for mine but without having a surface grinder, I always felt that I wouldn't be able to accomplish the final step to realize the needed accuracy.

I'm unclear as to how you implemented the use of EDM to produce these parts. Could you explain.
Thank you

Impressive work, and you seem to have some very nice machines. I would imagine raw materials are considerably less expensive in your neck of the woods. Cheers, Mike

My point is: don't be afraid to have some difficult production, you need to have a start, even an imperfect work, even failure should not be a reason to stop the production!
What I haven't had a chance to say is: After heat treatment and grinding machine processing, the final result of these two tool holders is ------ miserably broken and then given up, because of my ignorance of heat treatment and material science, they reached about 58HRC, but the toughness is very poor, so it is easy to break during use, because I chose DC53 material.
I will explain my current production method and process later, I hope you can have patience and wait!
In addition, I would like to know the model and size of your tool holder, as well as the detailed data of the tool holder. If it happens to be the same size data as the tool I made, I am willing to give away an imperfect production work, because the negligence in the production process has led to some minor defects, but the accuracy and effect of the use are not affected at all. You just have to pay the cost of shipping yourself (estimated to be around $40.00)! The V slot spacing of this defective item is 100.00mm, and I used a tool holder with 99.70mm spacing. I will draw detailed size data for your reference! If you are interested in making your own, I will provide you with some drawings and production process.

It is not finished yet, I have to wait for the rest of the tool holder to finish drilling and threading together

令人印象深刻的工作，而且你们似乎有一些非常好的机器。我想在你们附近的原材料会便宜得多。干杯，迈克

Thank you for your reply, I choose the principle of machine tools is to buy a good reputation of European machine tools, and then, according to their own needs for large or small modifications, so indeed my machine tool relative performance is very good. The two previously made were made using DECKEL-3NC which had not been reformed. Because CNC could not be used, I had to let the spindle work and then use the mechanical hand wheel to feed, which required huge physical effort.

So, soon after, I bought my friend's DECKEL MAHO80 and started learning CNC programming, and of course I had to make some tool holders to meet my needs.


Lazy use T milling cutter to complete machining T slots




Unfortunately, although there is CNC, I did not learn to use it, so I could only use G83 to peck a single hole, and then the electronic handwheel moved to the next point and repeated drilling, and it was difficult to complete 45 holes



The finish of the drill is very good because of the alloy bit used


Some height adjusting nuts were made using a lathe





I used three different kinds of steel to make the tool holder, namely DC53, 410 stainless steel and 42CRMO tool steel


However, I forgot that the hard-marked parts became indistinguishable after heat treatment

Thank you for posting those drawings. I will check the dimensions of my tool holders to see if they are the same. Also, thank you for the generous offer. I will let you know.
