UNDERCUTTING
MACHINE FOR MICANITE INSULATION OF FLAT COMMUTATORS
UMC300F (ACM75)
|
| UMC300 is
destined for the undercutting of the micanite insulation
between the commutator bars of starters and other DC
electric motors. It is especially suitable for processing
of new or rebuilding of old car starter armatures. The machine is equipped with
highly reliable indexing mecanism with photo-electric
sensor and step-motor drive, ensuring automatic
determination of the commutator bar number and perfect
alignment of mica segment with the tool. Automatic
detection and ignoring of fault signals. A
pneumo-mechanical sensoring mecanism is provided,
ensuring the automatic maintaining of the pre-set depth
of cutting, irrespective of the flat commutator level
variations.
Capacity: 90pcs/hr for
23 bars
