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.

Product News: Angle Head HSM Jet Spindle

Posted by Marie Orian on Jan 15, 2017 4:18:44 AM

How can you minimizing tool clamping, reduce the machining time, simplify machining processes, machine in hard to reach areas and cut costs while doing it? Try combining the advantages of high speed machining coupled with an Angle Head configuration for greater flexibility; increased accessibility in confined spaces, and expanded capabilities for three-axis machines.

Do You Have The TEST DATA To Prove It?

Posted by Marie Orian on Dec 5, 2016 6:58:52 AM

Increasing demands for quality and efficiency in machine tooling and processes leaves no doubt that end users have become a very discriminating audience. Therefore it's vital to provide them with test and validation reports that present reliable, in-the-field stats of product performance.

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

Posted by Sharon Weiss on Nov 22, 2016 7:00:00 AM

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 7:05:00 AM

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 1:57:10 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 7:00:00 AM

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.
