When Time is on Your Side, Use It!

I received a story from thread roller maker, C.J. Winter which talks about how the company used the recession to finally look at some of the easily put off things that needed to be done with the business.

Competing On A Multi-Spindle

For many high-volume applications, multi-spindle automatics are the right technology for production machining. Increasingly, that production efficiency has been pressured by changes in the needs of shops in the form of shorter run jobs and higher tolerances. This article looks at some of the steps one OEM has taken to address quick change-over issues on its multi-spindle machines and their tooling.

Military Supplier Delivers On Spec, On Time

When your only product is socket set screws and your primary customers are the demanding aerospace and military markets, quality and uptime are paramount. Your multi-spindle machines need to be reliable and easily reconfigured to produce a new part at a moment’s notice.

Continuous Cleaning System For Machined Parts

Virtually all precision machined part manufacturers require a method of cleaning their parts prior to shipment to their customers. And because many machine shops cut with oil, parts cleaning is usually a complicated multi-step process.

Relief For Sloppy Slides

Few screw machine shops can escape the inevitability of tighter tolerance demands from customers. Getting the most accurate tool travel from a screw machine is a key component to consistent part production.
