Wet vs. Dry Machine

Wet Machines include a filter unit that recycles and pumps the coolant back onto the part being processed and also includes a drying unit that removes the coolant from the part as it leaves the machine.

Some of the positives of operating a Wet Machine are:

A key factor when looking at a wet operation against running a dry machine is the chance of a fire that can occur when mixing different metals will be processed through the same machine. Some metals (such as aluminum and magnesium) can produce debris which are very flammable, and if run on a dry machine this dust can be ignited by the spark created when running carbon steel. We encourage you to using of a wet operation unit when the machine will be used to process different metals.

The parts being processed on a wet operation machine are kept cooler (which helps them from warping) and also keeps the abrasive belt from loading up and will enhance your abrasive belt life and hence giving you more value out of your abrasive belts.

The parts that are processed with a wet machine will come out with a cleaner finish versus a part that is processed on a dry machine due to the fact the coolant will clean out the debris in the valleys making it much cleaner and it will shine more than the part coming off the dry machine with debris still left in the scratches or valleys left by the last belt that was used.

A wet machine comes with an automatic paper filtration system that is built to sit directly underneath the wet machine which will result in a smaller area of shop floor needed to operate the wet machine versus a dry machine which will need a wet dust collection unit to collect the dust and grinding debris. This will end up taking up a larger area to operate the dry machine than the wet machine.

You will find that a dry machine is much cheaper to purchase (even with the added cost of a wet dust collector) than a wet machine with the same configuration. The dry machine is also going to be much easier to operate and maintain than a wet machine. We do go through all the pros and cons with you when you need to discuss this topic, of wet versus dry, as we will look at your overall process and what applications we will need accommodate.
