Six Things You Need to Know About CNC Fixturing

Fixturing is arguably one of the most complex and challenging (yet fun) parts of machining. Having the proper workholding and fixturing can make or break a production run, but in some cases, it can even break your part.

Fixture Plates and Why You Should Use Them

Machining parts is easy... work-holding is the hard part! Fixturing, part setups, and work holding is a never ending skill. Any time I have the chance to tour a factory, walk a trade show, or talk shop with another machinist, I try to learn as much as possible about workholding. There are countless creative uses for vises, soft jaws, 1-2-3 blocks, toe jacks, and other tools. A good workholding setup can mean improved surface finishes, more accurate parts, and better tool life. Furthermore, setups can simplify short production runs, ensuring that all parts in the batch meet tolerances. Process reliability is a key part of machining and making. The easier it is to implement good fixturing, the more likely you are to embrace it! One of the best ways to increase the functionality and work area of the machine table is with a fixture or tooling plate.

4 Bits of Knowledge That Separate a Beginner Machinist from a Pro

Learning to machine has long been considered a journey. There is always something new to learn, as well as skills and techniques to perfect. Machining knowledge often can’t be just simply taught, it often requires hands-on learning and some serious time at the machine.

Workholding of the Month: Tombstones

When you’re looking to do production work, or just looking to machine multiple parts at the same time, a CNC tombstone provides a way to fit several parts for many different operations into the same setup. When combined with an automatic tool changer (ATC), a tombstone can provide an easy solution to milling multiple parts that you can set and forget while your parts are machined. Tombstones, also sometimes known as pedestal fixturing, tooling tower, or fixture block, have two or more sides, typically four, that you can affix parts directly or attach various fixture plates. The Tormach Tombstone is designed to fit on our 6” or 8” rotary tables and the fixture surfaces are left as-cast, allowing users to fully customize their workholding by machining the tombstone to fit specific applications. There are two ways to really utilize tombstone manufacturing.

4 Machining Mistakes That Are Actually OK to Make

We’ve all been there – that moment of panic when the machine makes an awkward noise or the spindle seems like it’s making a rapid move just a bit too close to the vise. When you learn to trust the machine and your programming, things become so much easier, but there are still a few mistakes that folks worry about making that really shouldn’t be a concern.

Workholding of the Month: 3D-Printed Fixtures

Fixturing and workholding is not only important for milling and machining, but it’s also vital for prototyping and QC processes. While 3D printing may not be as rigid or robust as other forms of workholding, these can be part of the advantage to 3D-printed fixturing.
