Starrag Tech Days Highlight Turbine Technology Applications

A visit to Starrag headquarters in Roschacherberg, Switzerland during the company's 2018 technology days revealed new equipment, tools, technologies and machining strategies for turbine manufacturing. 

Machining Parts for the World’s Largest Digital Camera

SLAC is building the world’s largest digital camera, to be installed inside the Large Synoptic Survey Telescope. Getting there requires the machining expertise of shops like Keller Technology.

MMS Looks Back: 1990s - High-Speed Strategies for a High-Speed World

Amid rapid advances in information technology, machines and tools designed for more powerful controls and more capable software enabled shops of the 1990s to mill faster than ever before. This story is part of our 90th anniversary series.

Toolholders

Hardware for High Metal Removal Rates

Spindle power and shrink-fit toolholding are two assets this shop seeks to use to the extremes of their capabilities.

Adding Context to Advanced Milling

For all its focus on machines, cutters, parameters and tool paths, an expo hosted by Methods Machine Tools demonstrated that competitive hard milling increasingly requires looking beyond the workzone and even beyond traditional machining.

Cutting Tools

Applications Advance for Solid Ceramic End Mills

All they need is speed! Tools for roughing nickel-based alloys can be used in the same processes as carbide tools, just with high rpm and no coolant.

High-Speed Machine Spindles Reduce Cycle Times

Designed to reduce cycle times in a variety of operations, NSK America’s HES series of machine spindles includes two models programmable from 5,000 to 80,000 rpm.

Data-Driven Manufacturing

Increase Machining Efficiency through Machine Monitoring

A manufacturer that is distinctive for its attention to in-cycle machining productivity describes its efforts to obtain efficiency improvements outside of the machining cycle. The shop’s primary tool is a simple, daily, graphical recap that illustrates when each machine tool was and was not making parts.

Micromachining Evolution

Challenge Machine continues to add high-speed equipment for the increasing amount of micromachining work it is performing. Here are some lessons it has learned along the way, using tools as small as 0.001 inch in diameter.

CAD/CAM

The Costs and Benefits of Horizontal Machining

The shift from vertical to horizontal machining was even more expensive than this shop anticipated. It was also more valuable. Most of the shop’s machining centers are HMCs now—here’s why.

Turning Machines

Control Package Helps Speed Production

After cutting precision parts in one third of the original time, Task Force Tips was able to justify its initial investment in an Index automatic production lathe fitted with a Siemens control package.

Die/Mold

High Speed Leads to Lights-Out

This mold maker has become more competitive by establishing a high speed machining process that is predictable enough to confidently run lights-out.

Holemaking

Inserts Withstand Heavy, High-Feed Cuts

Swapping standard button inserts for a new grade from Ingersoll helped this manufacturer of downhole oil-drilling equipment double throughput on a troublesome arbor milling job in hardened steel.

What Your Handbook Isn’t Telling You

Tony Schmitz, professor at the University of North Carolina at Charlotte, gives a presentation on machine tool dynamics. Learn the role that this concept plays in realizing your optimal machining center performance.

Maximizing Power for High Speed Hog-outs

A reader asks a question related to the rated power of a machine tool spindle.

Cutting Tools

Improving Surface Finish During High Speed Machining

Many factors can affect surface finish. This answer to a reader’s question focuses on imbalance and frequency sensitivity.

The Online Optimizer

Coming soon: The Machine Tool Genome Project promises to let almost any machine shop use its machining centers more productively. Shops will benefit from tap-test findings without personally tapping any of their own machines or tools.

CAD/CAM

Software/Tooling Partnership Promises Easier HSM

High-efficiency parameters are calculated automatically—partly using a slider that lets the programmer set the level of aggressiveness.
