We often find rusty tool holders while using them. And excessive rust on tool holders can directly affect their performance. For example, rust can impact the contact surface between the tool holder taper and the machine spindle; it can cause vibrations during machining; also, it can decrease the lifespan of the spindle. If the toolholder inside is rusty, it can reduce the clamping force and affect the workpiece surface finish.

Here, we can give you some tips for maintaining the tool holder and preventing it from rust:

1.Daily maintenance is necessary after using the tool holder. You can effectively reduce the occurrence of rust, prolong the tool holder's lifespan, and maintain machining quality.

2.The best way to prevent issues with collets is to simply keep them clean. Keep the taper clean, detach the tool holder from the spindle, and use an air gun to remove metal chips and greasy dirt from the tool holder, especially those in the grooves and inner hole.

3.Proper use and maintenance is very important for these three parts: pull studs, collets, and nuts. If the pull stud comes out, it’s going to damage the spindle; the loss is huge. Use a cotton cloth or wiping paper to wipe off dirt and cutting oil from the surface. Nuts and collets should also be removed for cleaning and maintenance if applicable.

4.If the tool holder is left unused for a short period, it is advisable to remove the coolant supply unit and tool for maintenance.

5.Wear gloves first and apply anti-rust treatment to the surface and interior of the tool holder. Wearing gloves can avoid transferring moisture or dirt residue from hands onto the tool holder, which could result in fingerprint rust stains.

6.Store the tool holder in a rustproof bag and keep it in a clean, dust-free environment.

The above is the information about how to maintain the tool holder.
