Adjustment of Bearing Preload for High-Speed Spindles

Bearing preload needs to be carefully controlled and understood. Insufficient preload leads to low stiffness while excessive preload leads to higher temperature rise and even seizure. As rotational speed increases several factors cause an increase in preload: [4] Schematic drawing showing general arrangement of lubrication system 3/8 Steel tubing External by-pass line added to all […]

BASICS OF RECIPROCATING GRINDING

According to DIN 8589-11, reciprocating grinding is a peripheral longitudinal grinding process with a back-and-forth feed motion, in which the feed motion takes place gradually in small steps with a relatively high feedrate [DIN 8589]. 16.2.1 Process Characterization Reciprocating grinding is used for generating plain surfaces of usually large lateral dimensions. The grinding spindle is […]
