S1: Spindles

16.1

Brief Description

The primary function of a spindle is to set a tool or workpiece in rotary motion in order to facilitate machining.
Depending on the type of machine, the spindle must support the following functions in order to achieve this:
• Input of a direction of rotation for the spindle (M3, M4)
• Input of a spindle speed (S, SVC)
• Spindle stop, without orientation (M5)
• Spindle stop with orientation / Spindle positioning
(SPOS, M19 and SPOSA)
• Gear change (M40 to M45)
• Spindle­axis functionality (spindle becomes rotary axis and vice versa)
• Thread cutting (G33, G34, G35)
• Tapping without compensating chuck (G331, G332)
• Tapping with compensating chuck (G63)
• Revolutional feedrate (G95)
• Constant cutting rate (G96, G961, G97, G971)
• Programmable spindle speed limits (G25, G26, LIMS=)
• Position encoder assembly on the spindle or on the spindle motor
• Spindle monitoring for min. and max. speed as well as
max. encoder limit frequency and end point monitoring of spindle
• Switching the position control (SPCON, SPCOF, M70) on/off
• Programming of spindle functions:
- From the part program
- Via synchronized actions
- Via PLC with FC18 or via special spindle interfaces for simple spindle activation
