Keeping a written garnet log helps you track abrasive use and machine condition in waterjet bays, avoiding downtime and wasted material.
By Ms Thembisa Tau, MD, Dust
In South African machine bays, abrasive waterjets rely on a steady supply of good garnet to produce clean, repeatable cuts. Garnet is not cheap, and running out during a job or loading poor quality abrasive leads to stoppages, nozzle blockages or even wasted material. Without a simple daily log, it's easy to lose track of batch changes or forget when the next drum is due.
Most shops dont have fancy plant software. Operators scribble notes, shift leads rely on memory, and small mistakes can cost time and money. A printed log, updated at the machine, gives everyone a running record, so you don’t repeat old errors or forget to prepare for a big job tomorrow.
Set up a simple printed log sheet and keep it at the waterjet. Use a clipboard or laminate it if dust and water are a problem. Each time you load garnet, or finish a drum, make a quick note. Stick to plain words so anyone in the team can pick up where you left off.
Update the log after each cleaning, nozzle change, or if you spot a problem with the abrasive or feed line. This helps spot patterns, like a drop in cut quality when a new garnet batch is used.
If you’re unsure which garnet mesh size works best for your parts, or you want to confirm compatibility with your machine, send us a message through our contact form. We can also advise on how much garnet your bay should budget for each month, based on your typical plate thickness and job mix.
Our team can help you set up the first log sheet, recommend ways to store drums so they stay dry, and show you how to spot early signs of feed problems. If your operator training needs a refresh, let us know: Mr Ashlin Gounden can help with practical checks and record-keeping routines.
Skipping log entries leads to confusion, you might end up double-filling the hopper or running the garnet bin empty mid-cut. Another mistake is leaving the log where it gets soaked or buried under offcuts, making it unreadable just when you need it.
Often, workshops forget to check for damp in the garnet drum. Moisture clumps up the abrasive and blocks the feed line, especially on the coast. It only takes one missed check to bring the whole bay to a standstill. Keep the log up to date, and store abrasive drums raised off the floor and sealed tight to avoid this.
