We are finishing out the week with the Doosan lathe tackling some 316 stainless steel. We were running parts on both sides of a piece of stock so we could drill and bore the ID while turning the OD in the same operation. This allowed us to keep them concentric. In order to achieve the finished product, we had to cut them in half and face them to length. Unfortunately, the bar stock is too large to fit in the spindle, so the part couldn’t just be machined and parted off the bar stock in the lathe.

This morning, we had a stack of brass spacers to machine. We are knocking this easy little job out on the TRAK Machine Tools DPM3 while the VMC's are running parts unattended. These open style bed mills come in handy, you can turn the handles and drill holes like on an old-style Bridgeport, or you also have the option of running them in full 3axis CNC mode for more complex jobs. These parts came to us saw cut and just required us to add the half-moon feature that was easily done by plunging an endmill into them.

Op1 of this part was completed this morning on the 5th axis. We brought this single part down from 4 ops to 2 ops. Not only was it done faster, but it was also done more accurately. We are able to hold better positional accuracy of features from one side to another. Traditionally having to pull the part from the vise, rotating the part and setting up again to do the features on the other side adds the potential for errors and bad parts.

Five Axis Friday! This morning, we machined a small aluminum pipe spool part on the 5th axis. We machined the faces, thru bore and the mounting holes on either side first. Then mounted the part to an arbor in the lathe and did the outer groove feature. All that's left now is to box up the part and ship it to the customer.

Knocked out this little fixture this morning for a small production run of some thin discs we have to machine. We will be making a second identical fixture as well. Since we are able to hold 10 parts at once, and it takes about a minute to machine one of the parts this gives us a run time around 10 minutes. That will give our operator time to unload and load one fixture while the other one runs minimizing spindle down time.

It's finally Friday, and the start of a long holiday weekend! What better way to end the week then by finishing up 100 of these A2 tool steel parts.
We start out by machining each end of a piece of stock, so that we have something to hold onto in the lathe to allow turning the outside to size. Then it's off to the fourth axis where we add two thru bores 90 degrees from each other. From there we cut the stock in half to give us our two parts. Next, it’s back into a lathe to face them to final length, and finally back into the fourth axis for the 4 tapped angled holes on each end!

When we need quick and accurate indexing to machine shafts with keyways and multiple holes at different angles, we load them in the 4th Axis making quick and easy work of them.

We finished up machining all of these bearing housings yesterday. It took just 2 operations total utilizing the 5th axis so we could reach all the side features at once. We were able to get them painted by the end of the day so when we came in this morning the paint would be dry, and they would be ready for assembly.

These pieces here are part of an assembly we are working on in the shop currently. They require only the top and bottom faces to be painted. Instead of masking off all the machined surfaces during painting we opted to machine a wooden plug for the bore and cut the outer profile in a pc of plywood to fit over the part, so the paint only hits the surfaces we want. This saved us a lot of time and it worked flawlessly.

Today we were able to utilize our 5th axis machine to knock out this aluminum part in one quick and smooth operation! The 5th axis allowed us to machine the inside, outside, and top surface. After completing the top counterbored holes, the machine turned the part 90 degrees, front to back, and then rotated 360 degrees, left to right, to complete the taped side holes. The taped side holes are m2 x .4, and while that might seem small, they are nowhere near the smallest holes we have taped. Once the part was completed, we cut the part off from the piece of stock that was in the 5th axis vise.

For this little project, we used the Keyence IM to reverse engineer some brackets for our friends over at Primarch Racing. Primarch needed the brackets to be longer, so we added length to the back end of the bracket and increased the adjustability by making the mounting slots longer. After getting the brackets measured and drawn up, we loaded them in the Haas VF2 to machine the mounting slots and triangle cutouts which aid in keeping the weight down.

This morning we had pulley blanks our customer sent us that needed modifications.
In the 1st Op we are holding on to the hub of the pulley in the lathe to bore out the inside for bearings and a snap ring, while also putting a relief groove in the teeth on the outside.
In the 2nd Op we are again in the lathe and using a split ring over the teeth to hold on to the part to cut off the hub.
Only thing left to do now is bag and label the parts and ship them back to the customer.
