High Speed Electric Spindles designed for routing applications are equipped with bearings capable of achieving high RPMs and enduring high radial loads (side cutting). When entering the work piece with these spindles it is important to keep the axial loads low in order to prolong bearing life.

When programming your work-piece, entry angles should be kept from 0º - 20º off the table. This will keep axial loading low and allow feed rates at 100%.

When the work piece design requires a steep entry angle, the feed rate should be reduced according to the chart. This will minimize axial force on the bearings.

Above all, avoid "crashes" of the spindle into the table, fixtures and work-piece.

Specially designed Electric Spindles for drilling or boring applications are also available.
