Holemaking. A layperson might think, “what could be simpler?” But a machinist knows better because there’s a lot to consider when creating a streamlined toolpath.

At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.

Since their introduction about 20 years ago, replaceable-tip drills have become increasingly accurate and cost-effective alternatives to solid carbide units.

If you’ve ever seen industrial wind turbine components on the back of a flatbed truck rolling down the highway, you have a good idea of what a large, heavy, difficult-to-handle workpiece is. For example, with a single blade on the GE 1.5 mW turbine being almost as long as a football field, the entire blade assembly weighs about the same as 36 small cars.

Solid-carbide micro cutting tools about the diameter of human hair or smaller—some producing parts visible only under a microscope—are making a huge impact on manufacturing highly advanced electronics, automotive and aerospace fuel injection systems, and medical instruments and implants.

If John Winter of toolmaker Sandvik Coromant (Fair Lawn, NJ) were to start his own machine shop, all of his machines would be equipped for through-spindle coolant (TSC).

Cryogenics offer an alternative to traditional liquid coolants when conventional cooling methods can’t or don’t do the job well enough.

Although toolholders are known to be critical components in the precision machining process, the unique details that differentiate a standard toolholder from one that is designed for more precise, high speed work can be subtle.

More than 4,600 cutting tools items from M.A. Ford (Davenport, IA) are listed on MachiningCloud (Camarillo, CA), with more to come. M.A. Ford manufactures standard, high performance and custom cutting tools with worldwide manufacturing and distribution facilities. MachiningCloud is a product data provider for cutting tools, CNC machines and workholding.

Celebrating its 80th year, Kennametal, the Latrobe, (PA), tooling manufacturer, says it has solved the age-long problem of tool stability when drilling in deep cavities, alongside tall shoulders, and past bulky fixtures. Reaching deep inside a workpiece to drill holes can be challenging.
