Whitney Overview

Published in Galleries on 3/01/2018 by Ballscrew Guys

The most problematic axis on the Whitney systems is the refurbishment of the X-Axis ball screw which moves the sheet material. This screw is a Japanese type assembly with an external rotation bearing. There are no provisions on this machine to lubricate the ball screw. Meaning that after 3-5+ years of operation, the screw is often worn to the point of destruction. What many Whitney Plasma/Punch owners do not know, is that there ball screws are rebuildable at a fraction of the cost of purchasing a new one. Without the lead time waiting for removal, core exchange, shipping, and reinstallation. The rebuilding of the X-Axis in your machine, will typically take Ballscrew Guys 5-6 hours.

The Y-Axis and V-Axis are far for simple to rebuild and repair. But because these are exposed ball screws without protective covers, they are often contaminated quickly. Reducing the service life and accuracy of the ball screw. It is not uncommon that in high output and volume shops, that these screws need to be refurbished annually.

V-Axis Refurbished

It's always nice to have the table removed when we service the V-Axis. Regardless, we are not afraid to crawl "into the hole" to service this ball screw.

Whitney X-Axis

The X-Axis of the Whitney Plasma Punches do not have any system for auto lubrication. This ball screw is a sealed NSK external rotation bearing type. It gets packed with lubrication upon assembly and is left to run. It is critical that these assemblies are refurbished at least every 2-3 years at a minimum. This will prevent permanent damage to the screw.

These need to be cleaned, flushed, and regularly lubricated.

Whitney X-Axis Removed and cleaned

Pulling the entire X-Axis of a Whitney Plasma punch for full refurbishment. Typically we can rebuild this axis of ball screw in the machine. But, because of the lack of lubrication delivery to this axis, we are designing upgraded seals to increase the working longevity of this screw.
