Hurco VM10 - Dust Collector-VM10 G; Limit Switches and Dogs

3 - 28 Machine Maintenance 704-0212-209 VM Series Maintenance and Safety Manual
Dust Collector—VM10G
The dust collector vacuums graphite dust particles from the cutting area on the VM10G
machine.
The dust collector motor turns on when servo power is established in either Manual or
Auto Mode. When servo power is disabled, the dust collector motor remains on for 60
seconds before shutting off. The dust collector uses cartridge-style filters and downward
airflow to remove dust particles from the dust collector.
The dust collector monitors the differential pressure between the clean and dirty air
chambers. If the air flow is low, in Manual Mode the spindle motor and dust collector
motors turn off; when in Auto Mode, the machine is put in Interrupt Mode stopping the
spindle and the dust collector motor.
Filter conditions may appear on the display of the dust collector unit. An alarm and a
message appears on the control when the filters need to be replaced.
Remove, inspect, or change the filter cartridges from outside the unit by removing the
filter access cover and sliding the filter out.
Limit Switches and Dogs
 Monthly or 150-200 hours of operation: Inspect limit switches and dog fasteners for
damage.
Limit switches and dogs are mounted on each axis and are used to determine end-of-
travel and to establish reference points for initial machine zeroes.
Follow these steps to inspect the limit switches and dogs for cleanliness, loose
connections, or damage. If necessary, use an Allen wrench to tighten the limit switches
and dogs.
1. Position the X and Y axes at their furthest negative location.
2. Open the enclosure maintenance door on the side of the machining center.
• The X limit switches and both dogs are located on the machine base.
• The Y limit switches and dogs are located on the column base.
3. The negative dog for the Z axis is visible when the head is fully retracted.
Remove the left overarm cover to access the Z limit switch and positive dog.
4. Check the tightness of limit switch and dog fasteners.
Please refer to the dust collector manufacturer’s Installation and
Operation Manual for procedures for replacing filters.
