Have You Checked Your Insurance Lately?
Business insurance represents a costly but necessary investment for any shop. This article presents the findings of a Cutting Tool Engineering survey of the liability insurance purchasing habits of readers. The article also offers some guidelines for insurance shopping.
All Together Now: General Industry Coverage
This article looks at the close partnership forged between a toolmaker and a machine tool manufacturer. The alliance requires the two to share detailed information about proposed products as well as the customers each is working with. Such cooperation has made it possible to develop several new products and processes.
The Dry Cure for Coolant Ills
With safety and health precautions driving up the cost of using metalworking fluids, many shops are attempting to machine dry. This article looks at the reasons why a shop might want to eliminate coolants and the effects this decision will have on part quality and tool performance.
Grinding Research Pays Big Dividends
Grinding research has led to innovations in wheels and machines, which have expanded the range of applications grinding can be used for. This article highlights some of the research being conducted and the work that has made it to the shop floor. An accompanying article discusses CBN abrasives.
Diamond Tames Graphite’s Bite
Graphite electrodes are extremely difficult to machine because of the material's abrasiveness. This article explains why it takes an endmill with a CVD diamond coating and multiple flutes to cut graphite without wearing tool quickly.
Why Do EDM Wires Break?
Adequate flushing is needed to keep EDM wires from breaking. This article explains why wires break, and how dielectric fluid delivered with sufficient flow and pressure can prevent these failures from occurring even in less than ideal conditions.
Bonded Graphite Electrodes: General Industry Coverage
To produce graphic electrodes for EDMing large cavities, shops sometimes must machine the piece in smaller sections and bond them together. This article explains how to build and use a bonded graphite electrode so that a ridge at the electrode's bond line can be avoided.
Wire EDM Filtration Comes of Age
Centralized mineral filtration for wire-EDM dielectric fluid can remove contaminants down to the 1-micron level and dispose of them in an environmentally responsible way. This article describes the mineral filtration process and compares it to the other common filtration methods.
Tantalum and Niobium: Drilling Performance
Tantalum and Niobium are important components in the composition of carbide tools. They are also among the most expensive. This article explores how recent trends in metalcutting and tool usage will effect the supply of these two components.
From Presetting to Tool Management
This article explains how state-of-the-art tool presetting-and-measuring machines can reduce a shop's tool setup time while increasing precision. The article also describes how the additional functions of these high-end units can turn them into sophisticated tool-management systems.
Balancing on the Fly: General Industry Coverage
With the introduction of high-speed milling, tool balancing has become increasingly important. This article describes a system that can balance tools while they are mounted in the machine tool's spindle and rotating.
Harder, Faster: Turning Performance
The growing use of difficult-to-machine materials has driven the metalcutting industry to high-performance tools. This article reviews the trends that are behind most cutting tool research today, and it looks at the state-of-the art results of that research.
