| Get Out Of Your Tooling Comfort Zone |
| Too many shops are put-off by the cost of tooling, and unaware of how tooling might affect throughput and product quality. The technology of tooling has changed dramatically in the past 10 years, allowing cutting speeds to nearly triple and producing similar improvements in productivity. Many shops are having trouble keeping up with these advances but, luckily, tool manufacturers are anxious to share their expertise with customers to reduce cycle times and machining costs.

| Micro Tools Are The Right Medicine |
| Micro tools, optimized for an application, can have a dramatic effect on product quality and productivity. For example, a manufacturer of orthopedic implants, uses micro milling cutters to produce an artificial synovial cavity in a titanium artificial hip joint. Compared with earlier machining operations, the total savings are more than 30 percent, and throughput time has been cut from 16 days to only six days. Read Full Story |
| The Special World Of Small Tools |
| Tooling requirements change when tool diameter is decreased and spindle speed is increased. Also, the differing characteristics of workpiece materials, copper, aluminum, steel grades, and exotic materials such as titanium, graphite and composites, require that tool geometries and tool coatings be material-specific. The three components of a cutting tool - geometry, coating and substrate - define the correct tool for given applications, but the ways those components go together, and the importance of each, vary from one material to another.

| Inserts For Low-Stress Milling |
| A new grade of milling cutter inserts is coated with TiAlN by physical vapor deposition (PVD) and is designed for milling stainless steel and titanium alloys. The inserts are designed to generate low pressure and stress during machining. The manufacturer said coupling the grade with new insert geometries is especially effective for machining aerospace alloys, and recommends that high cutting speed and low cutting feedrates be used for these difficult-to-machine materials.

| High Pressure Coolant Pumps |
| New high-pressure coolant pumps are hydraulically balanced to reduce maintenance costs because there are no packings, cups or seals. These rugged, fixed or variable volume pumps are built to handle the abrasive particles found in machine tool coolants that can wear out conventional centrifugal, screw, or piston pumps.

| Versatile Tapping Fluid |
| A new water-based tapping fluid containing a custom blend of synthetic additives provides the cooling properties of a water-based coolant with the viscosity of a straight oil. The composition of the fluid provides higher viscosity and lubricity than many oil-based products while also providing the high level of rust protection expected from a synthetic fluid. The fluid not only prolongs tool life and creates better threads in tapped holes, but it also creates a safe and clean work environment for employees. Read Full Story |
