How to measure Cutoff Wheel Performance
Productivity And Cost Evaluation – Cutoff
The unit price of a cutoff wheel is not indicative of the overall cost to the user, since the number of cuts done by different manufacturers’ wheels can vary widely. Flexovit’s ‘Cutting Index’ lab testing indicates the true cost of the wheel by factoring wheel price with cutting index results.
CUTTING INDEX – A ratio that measures how much work a cutoff wheel will do in a particular application. It is calculated by material surface area cut, per wheel surface area used. The higher the number, the more work the wheel will do.
Measure the starting wheel diameter and the surface area of the material to be cut.
Make a set number of cuts on the material.
Re-measure the used wheel diameter and calculate wheel surface area used. Multiply the material surface area times the number of cuts to calculate the total material surface area cut.
Calculate results for cutting index. Factor in prices to determine wheel value.
As an example Flexovit tested a U.S. made premium wheel from a prominent manufacturer against a standard Flexovit USA manufactured Razorblade specification, A60SST. The results appear below.
- It will take 1.9 Competitor wheels to do the work of 1 Flexovit USA manufactured wheel.
- At published end user list pricing, you will pay total $9.14 for 1.9 Competitor wheels vs. $4.26 for 1 Flexovit, Razorblade A60SST wheel.
- Using this Competitor made wheel will cost your company 2.2 times MORE than using Flexovit USA’s Razorblade A60SST wheel.
