You Can't Cut it if you Can't Hold It
Read an article we published that speaks to the changes that many shops are experiencing when dealing with the trend toward low volume/high mix jobs and the increasing need for precision workholding.
Back in the day, workholding for turning operations was a cut and dry (pun intended) affair. A chuck or a collet was about as sophisticated as it needed to be. Soft jaws or hard jaws where put on the machine and high volumes of parts could be run across them with little or no adjustments necessary.
“Precision Workholding Offers Multiple Advantages” speaks to the changes that many shops are experiencing when dealing with the trend toward low volume/high mix jobs and the increasing need for precision workholding. Most turning centers are capable of producing parts in a single handling as subspindles proliferate. Operations 10 and 20 can be machined without intervention.
Producing parts complete creates an increasing demand for more customized workholding, designed to secure high-value workpieces. In the article, we highlight a Michigan shop that is using high-end workholding to deal with the market changes.
Here's a broad look at different ways to approach workholding, from bar feeders to collet chucks to robotics.
CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
An ongoing effort towards more efficient operations drove this shop to take a closer look at indirect material usage, subsequently leading to implementation of a new system for tracking toolroom inventory.
