Traditionally, one of the largest barriers to achieving high surface finish has been vibration. Considering the whole spindle system, vibrations can be induced by several different components. Whether looking at the concentricity quality and balancing of the tool, toolholder system type, spindle interface or interface diameter, there is an intrinsic vibration existing within the system [...]
Machine controls today allow for extensive dynamic tuning of machine performance. The most common values to look at when considering machine dynamics are speed and acceleration. Equally important as each of these is jerk. […]
A new technology exists that ensures proper grease distribution to the spindle bearings over long duty cycles. This new grease lubrication system applies a shot of grease every 70 hours to each of the spindle bearings to ensure proper lubrication. […]
