Checking the Abrasive Flow Rate
WAZER does not actively monitor and measure its Abrasive Flow Rate. However, the Abrasive
Flow Rate is a critical parameter, so you should check and monitor this regularly. It is also one of
the first things to check if your cut performance has seemed to change This rate will need to be
updated from time to time simply because of normal wear or from an unexpected event such as a
backflow.
Required Tools
•
Scale w/ accuracy of +/- 0.5g (+/-0.02oz) and
capacity of at least 200g ( 7 oz)
•
Cup with a volume of 250ml (8oz)
1. Start out with 3kg +/-0.25kg (6.6lbs +/-0.6) of
Abrasive in the hopper.
2. Open Abrasive drawer.
3. Remove Abrasive Valve Plug.
4. Select Setup and Maintenance.
5. Select Abr. Flow Rate.
6. Place (or hold) a cup or container below the
Abrasive Valve.
7. Now hit okay to begin the flow of abrasive.
•
If the valve simply doesn’t open consistently
see Machine Procedures > Pinch Valve
Teardown.
•
The timer will count while the abrasive is
flowing.
8. After the 1 min Abrasive Flow test weigh the
container with the Abrasive, then subtract
the weight of the container. This is the
abrasive rate per minute. The goal abrasive
rate is between 140 g/min - 162 g/min (4.94
oz/min - 5.71 oz/min). If the rate is lower than
that you should investigate your Dry Abrasive
system for the problem. If it is higher then
that your Abrasive Orifice is worn out, contact
Support for a replacement.
