To avoid crushing and ruining parts, Swiss precision manufacturer Micro-Matics turned to Masa Tool’s Microconic collet and cartridge system.
Since 1973, Micro-Matics of Fridley, MN, has been manufacturing CNC Swiss precision screw machine products including many kinds of contacts & pins, ground shafts, hardened bushings, rivets, screws, spacers and other custom parts for the medical, dental, aerospace, commercial, defense, computer, telecommunications and automotive industries.
According to Jason Wobig, Operations Manager, "Micro-Matics is primarily an aerospace and medical components, Swiss machining job shop. We make components that are thousandths of an inch up to an 1-1/4" in diameter. We started out with the old manual style, Cam driven Swiss machines and we're one of the largest Escomatic shops in the Midwest. And as the company's grown and evolved, we've turned into Swiss job shop, mostly Citizen machines like the M16, a L12, and a M32, as well as a few Star and Tsugami machines that give us a wide variety of capabilities."
A while back Micro-Matics was running a small medical part, a catheter part, that they were struggling with.
They had some custom collets made for pickoff and, according to Dave Thayer, Department Manager,
"It was a constant struggle. This particular catheter part has very thin walls, it got crushed with a standard M16 collet system because you have very little accuracy in how much tension you're putting on your collet. If you put too much force on it, my parts started turning to collapse into triangles. If you don't have enough tension on it, the part pushes back into the pickoff and you get varying part lengths and varying chamfer diameters. The parts would be out round and they wouldn't be on-center."
Wobig had heard about Masa Tool's Microconic™ sytems through Todd Pakiz, President of High Tech Representation Inc., New Prague, Minnesota. "Todd had told me about this system a couple years back. And we had been struggling with these parts. So I reached out to Todd and see if he's still selling that system."
Wobig continues, "I wanted to try this system for the catheter part which is a small thin-walled part approximately 0.040" in diameter and another 0.040" in length and with a wall thickness of 0.010". So I wanted something that wasn't crushing the part. It was really hard to adjust the machines pickoff spindle itself to any degree of accuracy without crushing a part."
What Wobig found with the Masa Microconic system was that they could set up the clamping with a gage pin and set the clamping tension with the Micrograd™ Dial Wrench which has little indicators to set an actual tension.
Cartridge and collet solution
The Microconic system consists of a cartridge and collet, with the cartridge fitting in the machine just like a standard legacy collet. The cartridge is a self-contained precision mechanism using the machine’s standard collet closing function, which means that the Microconic system can be used on any machine utilizing 5C, TF20, TF25 or TF37 collets.
According to Saccomanno "Since a collet system for any given machine must be made large enough to fit the maximum workpiece diameter capacity of the machine, the result is the standard collet mechanism is designed to handle the largest workpieces, which means it is excessively forceful and bulky when used for the smaller workpieces. Smaller parts get sacrificed, because they typically require a higher degree of accuracy and the workholding is more critical."
The Microconic system consists of the cartridge, which fits into your machine like a standard collet, and the Microconic collets which fit into Masa's unique cartridge. Every Microconic cartridge comes standard with extended nose for unsurpassed rigidity because of it's single piece construction.
"In fact, the cartridge is so accurate that it can be used as a gauge to verify machine spindle accuracy," said Pakiz.
Thayer explained how the Microconic system has worked for Micro-Matics "With the Masa system we're able to dial in a nice specific tension to hold that catheter part without crushing it or deforming it at all and having it on center. In a nutshell, we get better quality parts consistently with tighter tolerances. It's lead to a really significant improvement, it's increased throughput, so we have more parts at the end of the day."
"As a result of the implementation, the scrap rate on this part dropped dramatically once we added the new Masa system by at least 30%." added Wobig.
According to Masa Tool, the Microconic cartridge concentricity is guaranteed to be within 5µm (.0002") runnout and the collets are hardened and precision ground to the highest quality standards. The regular, UM10, 10mm collets, that Micro-Matics is using in their F20M10 Cartidge are available from Ø0.2mm (.008") to 10mm (.394"). In additon to the TF 20 spindles, the same collets can be used in TF25, TF37 and 5C sub spindles.
Applying technology to other applications
Micro-Matics has been running one of the collets for a couple of months straight now on a distal coupler.
Thayer explains, "The distal coupler part has a unique shape. It's not perfectly round. It has some small flats milled on either side of the part. It's like a cylindrical pill, like a capsule except with two sides of the long length milled in so there's flats on it. The part is 0.080" in length 0.040" in a cylindrical diameter. We then mill the cylindrical diameter 180 degrees from each other to a thickness of 0.030", so you're taking 0.10" off then drilling and centering two holes on each end of that through the flats."
"Our customer is extremely concerned about any collet indication marks or chip marks on the outside of that cylindrical diameter. The previous collets we were using were custom made collets that actually had the profile of the part basically machined into it" says Wobig.
Thayer picks it up, "It was a straight cylinder round collet it but it was split in half so it was like two halves of a collet so we were trying to keep the flats in the spaces and then the round cylinder on the collet part that's round. The holding portion it would move and we didn't have them pinned at all. And then we had the same issue as on the catheter part: If you squeeze it too tight you're starting to push the diameter into the flat so it would deform the OD into the flat and make deformed flats. If you squeezed it too hard, it would make the flat bump up. If it didn't sit perfectly right in the custom collet you'd have the split marks of the collet that start interfering with the transition between the flat to the diameter and it would make lines on the diameter."
Remedying the issues
Thayer continued "The extended nose pieces on the Microconic cartridge helps on the catheter tips because you can get closer up to where I actually have a supporting back end. Because if I'm too far away from that supporting back and you have more of a tendency to crush the front of that part. The Microconic gives me a better tension on the part. On the distal coupler, we have to use a boring bar, or a facing tool to create the back face, which is round. We'd have a lot of trouble trying to hold without nibs or anything on there. And this holds it so that the part stays a little more square, and we're able to turn it better."
When dealing with very small parts and setting with small gage pins, accidents do sometimes happen. "The only problem I've had with it was when somebody was trying to set the collet tension with a pin. They put the pin into the slot and not the hole and wrecked the collet. Because the pin was able to fit inside the slot so when they started tightening it up, and the pins started deforming the collet was wrecked because it wasn't in the hole in the center." said Thayer.
Masa has indicated that they will release a new TF 15 and TF16 Cartridge with an entire series of smaller 5mm capacity collets at IMTS 2022.
Microconic over-grip collets have unmatched rigidity and concentricity compared to other manufacturers. The same collets can be used in TF20, TF25, and 5C sub spindles. Microconic collets permit interchangeability between machines, and the collets fit in any Microconic cartridge, no matter which collet system is in the machine.
