One of mankind’s oldest manufacturing methods—making a hole—is now challenged by rapid advances, including new and harder materials, increased part complexity, ever smaller component parts, and the need for shorter cycle times.

So you’ve heard all sorts of good things about Swiss-style, sliding headstock CNC lathes and have been thinking about investing in one.

For the highest levels of competitive benchrest and extreme long-range (ELR) shooting, feats of precision manufacturing and machining are required for success. Like Formula 1 racing cars or PGA golfers’ clubs, world-class competition rifles are made with highly engineered precision parts.

The push to modernize technology-intensive sectors in Asia—such as automotive, aerospace and general engineering—is constantly stretching machine tool builders in the region to their limits. The demand is not just for standard machines.

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).
