As far as cost concerned, well, let's calculate it roughly in addition to quality improvement.
Cost of slats replacement for one standard laser cutter as below:
1. Raw steel material: 9 Sheets used for a complete slat replacement (48"x 96"x.125) x 2 tables. 60 USD per sheet, about 540 USD;
2. Many people to run the machine to manufacture the slats ( 3 hours) & remove the slat & put slats back (1.5 hours), averange 85 USD per hour/team, 382.50 USD;
3. Revenue loss of the machine during downtime: 100 USD per hour, then 400 USD;
In total amount for slats replacement once, 1372.50 USD. If 4 times one year to replace the slats, then cost will be 5490 USD.
That's only loss of ONE laser cutting machine. In fact, you can use one Slat Cleaner for tow or three laser cutting machines.
