We all used to think that 3D printing (additive manufacturing) was like magic –  parts just popped out of the printer perfectly formed – like a Star Trek replicator. While 3D printing technology is very cool (and getting ever-cooler) still, the completed product, especially using metal powders, can be fairly unrefined. A solution to achieving highly accurate, quality finishes on the 3D metal part surfaces that matter most, lies in combining two advanced technologies – 3D printing with high-speed CNC machining.

RAKE IT 'TILL YOU MAKE IT: Rake Angles at a Glance

Posted by Sharon Weiss on Nov 22, 2016 3:00:00 PM

Basic tool geometry is determined by the rake angle of the tool; which is always at the top side of the tool. With the tool tip at the center line of the workpiece, the rake angle is determined by the angle of the tool as it moves away from the workpiece center line location. Rake angles influence both tool strength and cutting pressure.

What if you're not an early adopter by nature; the kind of person who automatically says "if it's new, I'll take two"? What if you're more like "I'll wait a few years to see where this is going"?  There's nothing wrong with playing it safe and sticking with the status quo. However when a reluctance to go where few have gone before stands in the way of achieving more, competing better and growing your business, then it's time for a rethink.

High Pressure Coolant (HPC) Machining — a Tour De Force!

Posted by Marie Orian on Oct 20, 2016 2:05:00 PM

High Pressure Coolant (HPC) has proven itself in many dedicated turning and milling applications and on difficult-to-machine materials; at removal rates up to three times more than conventional flood coolant systems. Users report elimination of chip jamming, faster cutting and much longer edge life in outer and inner diameter turning as well as grooving, parting and hole-making.

THREAD MILLING - Better Than Tapping?

Posted by Marie Orian on Oct 6, 2016 8:57:10 AM

Tapping is still a commonly used internal threading process, since it's a relatively easy, machinist-friendly method. However the highly efficient thread milling technique is gaining ground fast in becoming the foremost method of thread cutting.

Creating a 'Steel Shield' Through Cooperative/Collaborative Metal Machining

Posted by Marie Orian on Sep 12, 2016 2:00:00 PM

Anyway you cut it, it's cheaper to manufacture in China; low wages, cheap rent, lax quality, etc.  Although they may be lagging now in the high-end market; precision parts, hard or exotic materials, compliance to standards, quick turnaround and so on, China's metalworking industry is slowly but surely closing the gap.

Beginners Guide to Swiss-Type Machining

Posted by Marie Orian on Sep 5, 2016 3:14:51 PM

Swiss-type machining has evolved well beyond what its original developers could have ever imagined. And although Swiss-type machines of the 21st century are not necessarily made in Switzerland, they are all primarily designed to turn small, complex, precision parts predominantly for the automotive, medical and electronics industries.

Ideal Partner or Machine Shop Identity Crisis?

Posted by Sharon Weiss on Aug 30, 2016 2:00:00 PM

Machine shops vary in many aspects; from practical expertise to work ethics; and the options seem endless. Sometimes it doesn't even matter what a machine shop is capable of doing, but rather what they prefer doing. What types of work do they like to do and what kind of jobs do they consider a hassle?

Machining Titanium: Is There A Way To Beat The Heat?

Posted by Marie Orian on Aug 23, 2016 2:30:00 PM

Titanium – it's an almost supernatural substance, with an amazing strength to weight ratio, the ability to resist fatigue and stress fractures in radically divergent temperatures, superior corrosion resistance properties, and wonderfully human-friendly biocompatibility. Parts made from Titanium and Titanium alloys are invaluable for use in ultra-harsh environments; from the ocean depths to outer space and even inside the human body.

Although shop owners may turn a blind eye to it, or coworkers may be reluctant to blow the whistle, sabotage in the machine shop is a serious issue — not to be swept under the factory rug. Not only does it cause productivity downtime and damage to machines, but most importantly, it endangers the safety and welfare of the workers.
