With many 3D milling applications demanding both shorter cycle times and smoother surface finishes, it’s time to review how you go about programming and machining parts. These four strategies will let you rough dramatically faster and achieve astonishingly fine surface finishes.
Machining capability drives evolution from race car builder to aerospace and defense contractor.
Chiron’s new DZ 22 precision machining center features twin spindles and a moving gantry design to rapidly and precisely machine various large, complex parts.
Sold and serviced by Absolute Machine Tools, the HMC is intended to be a low-cost, high-speed machining center meeting the demands of manufacturers with high-volume machining needs.
For machine shops with high-speed equipment already on the floor, brass represents an opportunity to capture new profits they might otherwise miss with other materials, according to the study.
GF Machining Solutions’ high-speed Mikron Mill S 400/500 Graphite and Mikron HSM 500 Graphite are dedicated specifically to graphite machining.
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.
Optimized roughing, also called high-efficiency milling, is an effective way to improve material removal rates and tool life for titanium and hard-to-machine alloys, but knowing when to use it is as important as knowing how.
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.
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.
Spindle power and shrink-fit toolholding are two assets this shop seeks to use to the extremes of their capabilities.
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.
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.
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.
A focus on repeatability, geometric capabilities and speed led this manufacturer of fine-blanking machines and components to embrace hard milling as its go-to finishing process, eliminating hand grinding.

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.
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.
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.
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.
By investing in five-axis machining technology, Advance CNC Machining has done more than just add new capabilities to its roster. It has found a way to achieve something that most of us strive for: a way to work “in the zone.”
