Whether on Swiss and other turn/mill centers, drilling and tapping machines, or with milling attachments, shops are doing more milling with small spindles than ever before. That’s partly due to the ...

Modern milling machines look much the same as they did 30 years ago. However, they now must cut superalloys, titanium, and high-tensile steels to closer tolerances and at faster rates than before. To ...

We sometimes wonder if designers ever actually use their own products, or even put them through some sort of human-factors testing before putting them on the market. Consider the mechanism that ...

Balanced toolholder assemblies pay dividends in longer spindle and tool life and, especially, in greater metal removal rates at all cutting speeds. Photo courtesy Emuge Corp Modern milling machines ...

Spindles are machinery subsystems that integrate shafts, bearings, and power-transmission components such as belts and ballscrews, motors, and in some cases, drives and controls to output axial ...

Both the main and second turning spindles operate at 4,000 rpm, while the compact milling spindle comes standard as 12,000 rpm (24 hp/22 kW) and 20,000 rpm (24 hp/22 kW) as optional. The machine ...
