Keep The Change
Any organization that is faced with the need to change things wrestles with the questions of what to change and how to sustain that change. What to change will obviously vary from company to company and industry to industry. Often, the answer to this question is presented to us by external forces. For example, chan

Compact Handling Facility Sticks To Basics
Shops consider a number of factors when justifying automated parts storage systems, including cost, required floor space and machining application.

Turning Is Optional
The part requires only milling and drilling, but it is still run on a lathe. Except for the cutoff tool, all of the turret positions on this lathe hold rotating tools. In other words, turning is not essential for using a lathe effectively. This application illustrates the productive possibilities of a modern turn-mill machine.

Synthetic-Diamond Dressing Tools: Why Not Use Them?
Synthetic-diamond dressing tools are often a superior alternative to natural-diamond dressing tools for conditioning a grinding wheel. The reason is the consistency that the synthetic-diamond tools bring to the process.

Consider L:D When Choosing A Lathe For Small Parts
Should shops always defer to Swiss-type lathes to process small, long and often complex parts? Not necessarily. As a general rule, a Swiss-type is most appropriate for machining workpieces with L:D ratios of 4 to 1 or greater. Parts with lower L:D ratios may be machined economically on turn-mills.

When Four Spindles Make Sense
For the right applications, four-spindle CNC chuckers offer practically zero delay for part loading. That’s because two spindles can be loaded while the other two are making chips.

When To Use A Spindle Chiller
Because conventional spindles on machining centers are typically designed with a fixed bearing preload (no springs), there isn’t any compensation for the thermal expansion that occurs from heat generation. Higher temperatures cause the bearing raceways to expand and tighten. This causes the bearing system to increase its preload beyond the original setting, which leads to increased axial and radial loading on the bearing system.
