CNC Coolant Saver Savings Calculator

Estimate how much coolant, disposal cost, and manual handling you could eliminate, and understand your potential payback period in minutes.

Industrial CNC machining operations lose significant amounts of usable coolant every year through swarf removal, drag-out, and waste handling. The Wogaard Coolant Saver recovers that fluid and returns it to your machine's reservoir automatically. This calculator estimates the real, site-specific savings based on your operation, using conservative assumptions from real-world CNC machining environments.

Coolant Saver Savings Calculator

The Wogaard Coolant Saver recovers coolant carried out of the machine with the chips, the wet coolant that pools in the bottom of your chip bin and gets hauled away with the swarf. This calculator estimates how much of that drag-out you can recover and return to the sump.

Your inputs

Coolant lost to chip bin (gallons / day / machine)

Coolant clinging to chips that ends up in the swarf bin. Wet chips can carry away up to 12% of coolant by weight, and total daily losses (drag-out, splashing, misting) typically run 5-20% of sump volume. High-production bins commonly collect 5-20+ gallons of liquid coolant. Tip: weigh a full bin wet vs. dried to confirm.

Operating days per year

Single shift ≈ 240 days. Two shifts ≈ 480 (use 365 cap with higher daily drag-out instead).

Mixed coolant cost per gallon (USD)

Cost of ready-to-use coolant (concentrate + water at typical 5-10% mix). Most US shops pay $3-$8 per gallon mixed.

Disposal cost per gallon (USD)

Drier chips also mean less liquid going out with the waste. US averages: $20-$200 per 55-gallon drum (~$0.36-$3.64/gal).

Number of machines

One Coolant Saver is required per machine. Savings scale with machine count.

Estimated results

Annual savings

Recovered coolant returned to the sump (up to 95% of drag-out) plus reduced disposal volume.

Monthly savings

Estimated payback

—

Payback assumes one Coolant Saver per machine and scales with machine count.

Additional operational benefits (not included in the calculation):

Reduced manual handling of wet swarf
Less coolant drag-out and mess around machines
Improved housekeeping and shop safety
Higher swarf value — drier swarf achieves better scrap prices
Reduced frequency of waste collections

Why coolant recovery matters

Reduce coolant purchases

Recovering and reusing coolant that would otherwise be lost with swarf removal directly reduces your annual coolant fluid spend, typically by up to 50% per machine.

Cut waste disposal costs

Less coolant going to waste means less to dispose of. With disposal costs running at $0.50-$2.00 per gallon, reducing waste volumes by up to 90% delivers significant annual savings.

Improve shop floor conditions

Drier swarf bins mean less mess, less manual handling risk, better housekeeping scores, and higher scrap value from your swarf, benefits the calculator doesn't even capture.

How the Coolant Saver works

Step 1

CNC machine generates coolant-laden swarf

Step 2

Swarf conveyor moves swarf to bin, coolant drags out

Step 3

Wogaard vacuum unit recovers coolant from bin

Step 4

Recovered coolant returned to machine reservoir

The Coolant Saver connects to your existing coolant pump pressure and uses a venturi effect to create suction at the vacuum cup in the swarf bin. No electrical connection required, it runs entirely from your existing coolant pump. Typical installation time: 30-45 minutes.
