Pierson Workholding is a company dedicated to advancing the CNC Machining industry through innovative workholding products. We design products that track with advances in CAD, CAM, High-speed Machining, and 4th and 5th Axis equipment.
PRO & MINI PALLET SYSTEM Our pallet systems are the ultimate in high-density, quick-change workholding. You can easily swap 20, 30, even 50 parts in seconds while using the full travel of your machine.
SMARTVAC 3 If you have thin, flat parts that cant be held in a vise, then our vacuum workholding system is a perfect choice. It's simple and powerful, yet efficient. It's also customizable for those complex part shapes.
ROTOVISE PRO The newest addition to our workholding family. Bolt it to any common rotary unit and you'll be machining multiple parts with access to multiple faces, giving at the least a 12x productivity boost over a standard vise.
Hi Jay Another great video. At the 1:05 minute mark there is a technical error in the explanation. The clamping force depends on a number of factors. These are :-- thread pitch, coefficient of friction between thread and nut, PCD of thread and applied torque. Your Rotovice would have a smaller thread PCD so on that basis alone the clamping force is higher. Basically clamping force is inversely proportional to PCD of thread. e.g. double the PCD and the clamping force is halved. Cheers
Hi Jay Another very informative video. When you found the length error with your various tool setters was the tool rotating as part of the tool setter macro or did it not matter?
Nice work Jay! Can you comment on how low volume repeat products can be evaluated for High Density Workholding? Something like comparing 10/quarter to 100/week 20 minute cycle parts? 100/week seems obvious to do, but 10 every 3 months not so much; what method do suggest for deciding when to and when not to use HDW?
Great question! I'd focus on using standardized bar stock widths and design fixtures to take care of Op1. The same fixture could potentially run different parts. I have a FF episode planned that will show off that approach.
Like today you can't get electrician without giving him 200 $ for simple work, it will be the same with machinists in next 5...10 years. Labor shortage is another term that managers as most useless employee in the world (except few % that actually do something good) to justify their incompetence
How are you suppose to break the mentality of "if it ain't broke don't fix it"? I can't even drag the other machinist into the 21st century methods of machining. Let alone for them to use their cycle times to do something else productive.
Nice product , nice video, just 1 question. It seems like maybe you could have made your pallet just long enough to hold 4 rows of your vacuum chuck part without a lot of problems but obviously I am not aware of all the parameters. Thanks for sharing
We looked at that but if we squeezed them in the material on the ends would have been too thin. Of course, a 1/2" longer pallet would have allowed that but we like to use our standard pallet sizes whenever we can.
As always great and informative video! Really thought provoking. Have you thought about a small pallet changing vertical like a brother r for these kind of parts? With a 4th axis on each pallet you could hit all six sides and load the parts time independent of when the cycle is finished. I think that would be a great next step. As you only have high quality personnel, the additional machine type and controller shouldn’t be that much of a hassle.
LOTS of reasons but I'll give you a few. For starters, this part has no turned features which immediately disqualifies it to be run in a turn/mill. Our general opinion is that live tool lathes are terrible mills. Compared to a mill, they have worse surface finish, low spindle speeds, limited travels, generate high toolblock heat (wear) and tool size is limited. Op1 alone would have required 9 live tools in a 12 station turret.
@@cgpmachining brother is a difference story I own an s700 and I'm aware of the benefits. You can't compare a brother that rapids at nearly 800 IPM faster and the tool changes are way faster to a Haas. That wasn't the point of the video
@@LoneWolfPrecisionLLC I am only responding to it being a 2 minute part, my thoughts on the fixturing are best kept to myself. By the way I have an R650 with a Brother rotary on each table.
80% Kyocera. But you're right about how long it takes to change tools on BMTs. For that reason, we design our parts to use common materials and common inserts. The best setup is no setup.
I run 6 of these at my work. I thought I broke one today and was really freaking out. The machine alarmed out and I reset it and thought I unclamped the sub spindle Chuck and it didn't. Then I jogged the B axis over with a part clamped in both chucks and it snapped the steel part.
I agree that the loss of a tool slot isn't ideal. Playing devil's advocate to this, however, what's the probability of your VMC/HMC utilising 100% carousel tool space capacity for any given job? Unless your leaving unused tools in the carousel, which in this case is no different to a chip fan. 🤔 🙂 the only variable that skews this theory is a low tool holding capacity?
@@Lewisdowning_ My main VMC has two slots that I swap regularly, the other 22 are a pretty standardized toolset that isn't worth jerking around to make space for a chip fan that wouldn't add a benefit equivalent to the loss of a slot. The external air knife is almost like adding an extra tool pocket, which is pretty cool.
Jay, you are a gift for the CNC human branch. Thank you for your help and generosity via the You Tube channel. Be Blessed in all your ways and means, your family and your CNC crew. Salutations from France.
It just that new people see it as something they want to learn and the older people see it as something they already now some not all, think they have learned everything and don’t need help.
Yup i have a few questions. Throughput. Why does it matter so much? You can throw silly "what ifs" at anything but the two circumstances I'm about to lay out, I feel, are perfectly common. They are also "anti-lean" (?) , and ignore "total throughput" , so I hesitate and feel I am missing something, but this seems perfectly logical to me. 1. Customer needs to place an order today. So they do, and we get the job. They have a deadline, and the job sits for 6 days. While sitting, no person or resource spends a single second or penny on it. It just sits in someones inbox or to do list to enter the order. Then they enter it, we do it in a day, ship it 3 days early, done. Can we not say throughput starts when the work starts? 2. Customer places order today. Its a big 150k order. We could run ALL of our equipment and people on it, to get it done super fast. fastest throughput possible. Its due in 6 months. So we do. This is fastest throughput. Except a problem - we missed a bunch of great opportunities because we had no capacity. Job is finished and no work. It would have been better to run the job out longer, over time, and used some of our other resources to do other things. Wrong? Sure - the opposite could happen, where you drag the job out a bit and a super good opportunity comes along and if you had done that first job faster you'd have the capacity for it and now you don't becuse you cant do both. But, by leaving yourself with some open capacity, you leave the door open for opportunities and can take them when they come - rather than passing on some and hoping more come later. Yeah?
Standardized cutting tools or a first choice tooling program is a huge step in the right direction. My last shop had a mix of tooling. One guy would program a job with a material specific tool and the next guy would use general purpose tooling. It led to wildly different part quality and cycle times.
I tested this by making my vac fixture without any clearance between the part and plate. I just made the grooves for the O-ring and the vac port leaving a facemilled surface. I put a part on the fixture, pulled 27"s of vacuum, and then pushed the part off the fixture without much effort. Next I cut .005" of clearance in my plate leaving the minimum of islands to support my part, put a part on, pulled 27"s of vacuum, and tried to push the part off, but wasn't able to. After this test I concluded you do want some clearance between the part and vac plate as it does make a big difference in how well you hold your parts. The part was a 9" x 12" sheet of 3/4" thick polyethelene. I do love vacuum workholding but think custom fixtures made specifically for the part is the only way to go. Or start with a big flat plate with one vac port in the middle and cut some rubber sheet to fit your part and go. This is my go to for short runs but you will need a higher flow pump and larger coolant separating tank as this method doesn't seal as well as O-rings.

Always loved this idea -- as soon as we saw you doing this a few years back we bought one of those Amazon motorized winches so ours has a little pendant to move up and down.
First, I admire and respect your accomplishments, your a smart cookie. This is just factual info that may or may not be applicable depending on your level of accuracy. Even leaning against the machine's front will move your machines tram because of the way the sheet metal is attached, i have many NC's a few different brands. Don't believe me , put a tenths indicator from spindle to table or vise and watch the needle move as you put your weight leaning against the front of the machine. Hanging over 200 lbs from the sheet metal may be moving your machine out of TRAM. Just info.
