Drilling Deep Holes On A VMC
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.

The Dynamics Of Better Drilling
Vibration is at the heart of a variety of common problems in machining holes. Mathematical analysis is helping to bring about a better understanding of hole-making processes...including how these vibrations behave, and what steps to take to bring them under control.

Reclaiming The Hole-making Process
A shop that had been farming out hole-making operations on oversized components brought this work back in-house after acquiring a large-format, CNC drilling machine. The process now can be done more quickly, at lower costs and on schedule, with many workpieces machined as assemblies instead of separate pieces

Multi-Axis Drill Sharpening Made Easy
Today, metalworking is privy to some very remarkable performances by the combination of things mechanical and things electronic--mechtronics. We've seen the reality of lights out shift operations. Programming systems that make what was state of the art 5 years ago seem like writing with a hammer and chisel. An example of the melding of mechtronics is this new drill sharpening system.

Smart Boring Bar Auto-Comps
Because boring is a finishing or semi-finishing operation, there is generally little or no margin for dimensional or surface finish error. In production, dimensional accuracy of a precise bore can be negatively affected by tool wear over time.

Sizing With Tool Nose Radius Compensation
Most turning center users use wear offsets for the purpose of holding size over the course of a production run. And with most of the tools used on turning centers (turning tools, boring bars, grooving tools, among others), all production run sizing should be done with wear offsets.

It's common to have to rerun tools. If you find a problem during the program verification with the eighth tool, for instance, you'll want to restart the program from the beginning of tool number eight rather than having to rerun the entire program just to get back to that point.
