Swarf is telling you something
Swarf, which is the result of particles being removed when grinding hard or difficult-to-machine materials, tells a story.

KENOVA Set Line V9xx Presetter and Shrink-Fit Device
Kelch offers a new system concept for a tool presetter from the KELCH KENOVA set line V9xx-S range. The focus here is on the redesign of the shrink fit equipment and side unit.
Industrial Robot Loader
ANCA Inc. custom-designed and built a new industrial robot loader for exhibition and demonstration purposes and is currently not available for sale.
B5490 Epoxy Bond
Buffalo Abrasives Inc. says the B5490 is an epoxy bond that is durable and easy to use, designed to run cool, generating less heat, thus less chance of burning. The bond eliminates chatter by providing a softer, more-forgiving grinding action.
OSG on cutting aluminum auto parts with Micro Technology
Micro Technology Inc., Tullahoma, Tenn., makes parts that are used to mount to automotive engine blocks to be robotically transported through assembly lines. The company uses HAAS VF-3 with CAT40 taper tools. One part is 6061 Aluminum with a tolerance requirement of +/- 0.002" and was being machined with a face mill at 3,000RPM 120IPM with 1.25" axial and 1.2" radial depth of cut. The challenge: Improve productivity without sacrificing quality and accuracy. OSG Tap & Die describes their solution in a recent web feature:
What’s shakin’? Seco Tools on vibration control
Seco Tools looks at passive and dynamic vibration control in a recent technical article on the company's web site. In metalcutting, vibration is generated by the changing forces that occur when making chips. The intermittent forces are apparent in the interrupted cutting process of milling and also appear in turning operations when the toolholder bar is periodically loaded and unloaded as chips form and break. A passive/dynamic approach to vibration control for tools involves application of a tuned mass damper concept.
ITAMCO ramps up additive manufacturing
ITAMCO (Indiana Technology and Manufacturing Companies) is delivering components to the medical device industry made with their new EOS M 290 additive manufacturing printer. The EOS printer was delivered in June 2017 and ITAMCO was shipping components to a medical device supplier in August.
Shop Operations: A fresh look at 1-2-3 blocks
Many machinists fondly remember their early training or apprenticeships when they made 1-2-3 blocks from scratch under the watchful eye of a master toolmaker. These young machinists carefully machined the blocks oversize, heat-treated them and then ground them to size. They quickly learned that precisely holding size and geometric features to close limits is more challenging than it seems at first glance.
16-inch x 60-inch Engine Lathe
The 16-inch x 60-inch engine lathe from Palmgren has the power to deal with heavy metal removal. It has the accuracy and control to handle precision fine tolerance turning.
Lead Angle: Targeting markets high and low
The boost in productivity that the latest cutting tools provide enables manufacturers to reduce the amount fracking companies pay for parts.
Cutting threads with your mill
Cutting threads is an important element of machining. Even if you aren't into making your own, custom-sized threads, it still helps to know how to create them. We've seen customers get pretty creative with their machines and cutting methods, but with a Tormach mill, there are three main ways to cut threads.
