Trim Cutter Services

We understand the importance of keeping your extraction system operating to its optimum level at all times, so we offer two types of trim cutter service. Depending on the application and operating hours, you will need to have the knives on your trim cutter re-sharpened/replaced and set.

The re-sharpening and re-setting of the knives is a very precise procedure with clearances being set as little as 0.00025″ (6.35µ) and must only be carried out by a skilled engineer who is familiar with the particular cutter and who has been suitably trained in the use of surface and cylindrical grinding.

Trim Cutter Servicing Options

We provide two options for you to choose from:

1. Cutter exchange (best for continuous cutter use)

Once you have informed us that the knives are ready to be re-sharpened and set, we will arrange for a completely refurbished, serviced, replica cutter to be sent to you. When you receive the cutter, it should be swapped with the worn cutter. The cutter exchange option means that you will only experience a few minutes of downtime and maximum operating efficiency will be restored. The worn cutter must be returned to us within 21 days.

2. Re-sharpen & set (best for occasional cutter use)

This option is suited to processes where downtime of the trim extraction system is not detrimental by the cutter not being in operation for a while (up to 2 weeks). We ask that you return the cutter to us for the knives to be re-sharpened and set by our specially trained engineers. In addition, a thorough internal inspection, including bearings, and clean up procedure is also carried out. This service means that your cutter could be out of your system for up to 14 days.

*It is very important to note that the lids and bases should never be swapped between cutters under any circumstances.
