What’s the real cost of in-house tool grinding?
Now let’s look at what it would cost if you were to grind tools in-house.
Calculating the cost of running a CNC tool grinder. We can calculate the cost of running a CNC tool grinder.
If we run 1 shift at 40 hours per week we can calculate the machine will run productively 2,337.5 hours. Based on this utilization, we can calculate the machine running costs and depreciation.
Assuming an initial investment of $240,000, the machine costs just over $65,000 per year to run. This calculation includes depreciation, power consumption, tooling costs, and maintenance. So the hourly cost of the machine works out to be $28.09
Of course, we also need an operator to run the machine and based on average wages and benefits, a typical CNC machine operator would cost $18.33 per hour.
Adding this to the hourly machine cost of $28.09 from our previous calculation, we get a total hourly machine running cost of $46.42.
If we use this figure with some typical tools, we can see the following…
