The Phase II QCTP comes with several toolholders but more would be better, allowing more bits and the clamp knurler to be instantly available. The only problem is the price of the AXA holders, typically upwards of 1. Bay, more from a regular supplier. It is possible to make toolholders with a mill, given a dovetail cutter. However, dovetail cutters are expensive too. The frugalmachinist had the answer for both the dovetail cutter and the toolholders. Dovetail Cutter The cutter was turned from a 1. All turning was done without removing the work from the chuck to ensure concentricity. A small shoulder was left on the shank to allow resetting the depth of the cutter in the holder in case it was removed to change inserts.

The slope was turned to match the 6. TPEG 3. 22 carbide insert the bottom is 1. A very small dot was put in the center of the bottom for reference using a center drill in the tailstock. A split sleeve was made to fit the QCTPs boring bar holder to accept the 12 shank the dovetail cutter to be was inserted and tightened into the boring bar holder. A scribing block was used to mark a horizontal diameter line through the center dot previously made on the bottom of the cutter. The boring bar holder was then mounted in the mill vise and a machinist protractor was used to orient the vise so the seat could be milled for the carbide insert. The mounting area was milled down until the face of the insert was exactly in line with the previously scribed diameter line half of which was, of course, milled off in the process. Retraction Tool Holder' title='Retraction Tool Holder' />The inner edge of the TPEG 3. The back of the TPEG insert is smaller than the front and the back should extend beyond the 6. The insert is installed with super glue and the center of the mounting hole spotted, the insert popped off and the hole drilled. I drilled the hole completely through, tapped it 6 3. The cutter was removed from the boring bar holder and a flat was milled on the shank. Using the Dovetail Cutter. Home made cutters dont come with instructions for use so it took some experimenting to decide how to make dovetails once I built the tool. The bulk of the material is removed with normal milling techniques to leave a large slot. Then, the dovetail cutter is used to cut the sloped section of the dovetail. With the cutter stopped I lowered it to touch the bottom of the large slot, then raised the cutter 5 thousandths. I started with 4. Subsequent passes removed 2. This dovetail cutter is a type of flycutter and makes the same noise as it operates so I arrived at the above settings based on the sound of the cutter. I tried various other approaches with poor results YMMV. Last Updated 11272017 237 PM. AUGER SPECIALS. FOR ADDITIONAL INFORMATION CONTACT MARYANN AT 516 536 7375 OR EMAIL rigssunmachinery.

Attempting to cut the complete dovetail depth in one pass seemed to go fine slightly slower feed required but part way through the tool was pulled down and began to mill the center area in addition to the dovetail thinking something wasnt tight enough I tried this a second time with the same result your tool might work better. From the carbide inserts perspective, this dovetail flycutter provides one long interrupted cut. I didnt expect the insert to last long in this application but it survives reasonably well at 4. I was able to complete 2 toolholders before I had to rotate the insert. Running the cutter at 1. There is not a lot of clearance between the sloped section of the cutter and the work so chips get in between and gallpolish this area on the cutter. When the cutter chipped it caused rapid galling of the sloped area because the insert wasnt removing the material so it rubbed the cutter it pays to watch for this to avoid damaging the tool irreparably should an insert fail. Operating at 2. 00rpm might increase insert life considerably at some loss in feed rate. The dovetail cutter can also be used as a facemill of sorts. When facing, the cutter has a wide contact area so it is wise to take shallow cuts to avoid chatter I took 5 mils out of the large slot on one tool holder as an experiment and it worked nicely. Avoid facing while cutting the dovetail, this would make it hard to tell if the cutter moved downward, as happened when I tried to cut a full dovetail in one pass. Tool Holders. The raw material for my toolholders was 3 pieces of steel from a local machine shop which was kind enough to cut it to length and throw in a chunk of scrap aluminum. I used the aluminum to test the dovetail cutter and make a DTI holder that fits the QCTP. Retraction Tool Holder' title='Retraction Tool Holder' />The AXA type toolholders are 3x. The length and thickness of the raw material required adjustment, done with the big face mill included with the milling machine. The ends were squared and all were within a couple of thousandths in size, simplifying measurements and clamping during following operations. I dont have a roughing cutter so I used a 18 slitting saw to remove the bulk of the material from the slots for the tool and dovetail. This was slow but left a nice finish in the tool slot for the tool to sit on I made one slot with an endmill but the finish wasnt as good. Cutting dovetails was interesting because the width is more critical than I expected. I had read about HSMs making a precise dovetail test gauge to verify the size but didnt appreciate what they were dealing with until I tried it. ToolHolders1.jpg' alt='Retraction Tool Holder' title='Retraction Tool Holder' />I came up with a crude scheme which works for making a small number of dovetails. I placed a Phase II toolholder in the mills vise and positioned the stopped dovetail cutter so it touched one side of the dovetail, then set the mills horizontal stop for this point and similarly for the other side of the dovetail. The dovetails were then cut using the stops to get close to the correct size the width was a few thousandths under because of the method used to set the stops. Then, the dovetail was tried on the toolpost and widened 3 thousandths at a time until it fit. File the corners as needed if they interfere with the fit I found that looking along the length of the dovetail with a light at the opposite side helped to detect any interference. The mills vise is precise, allowing this trial fit technique to work nicely of course, the holder being machined was re installed in the vise with the same orientation each time. An obvious alternative which wasnt so obvious at the time is to remove the toolpost from the lathe and use it to test the holders without removing them from the vise. Matching metric setscrews were used to hold the tool bits in place, allowing one hex key to work for both purchased and home brew toolholders. The long metric setscrews for setting height werent available locally so for now and perhaps always Im using 1. I dont have a way of bluing the holders so they will stay as machined. The DTI holder is higher than the toolholders and has a fixed pin to set the height above the tool post because this neednt be adjusted in use. The clamp was copied from a nifty Starrett design and works better than the clamp on the inexpensive magnetic holder I purchased as usual, I copy only the very best A Tangential Tool Holder for the QCTP Click to Enlarge A tangential toolholder was on my list of things to try for a while but I procrastinated because I didnt want to lose the convenience of my QCTP the ease of adjusting tool height plus the ability to instantly change tools is very hard to give up.
