GPG: Grind-Plate-Grind process explained
When a cylindrical surface, such as the OD of a shaft or the ID of a tooling taper, becomes worn or damaged, we use a process referred to as grind-plate-grind (GPG) to restore dimensions to original OEM specification. First, we pre-grind, also referred to as “green grind,” to remove a thin layer of material and smooth any damage. Next, the part undergoes an electroplating process to apply a layer of hard chrome to the desired area. This builds up a durable surface that is slightly oversized than the final desired dimension.

Machine Tool Spindle Bearing Lubrication: What To Know
Spindle bearings must be properly lubricated to maintain a film of lubricant between the rolling elements and the bearing raceways. Without lubrication, the rolling elements will have direct contact with the raceways, and this will result in heat, race deterioration, rolling element deterioration, cage disintegration, and ultimately bearing/spindle failure.
There are several methods of lubrication used for spindles.
5 Key Reasons Why Your Spindle Repair Shop Should Offer a Spindle Support Program
After a spindle repair is complete, one of the best tools a repair shop can provide its customers with is a ‘spindle support program.’ This program should offer premium content with reports and recommended corrective actions for incoming spindles, as well as tips, tricks, and how-tos to keep a rebuilt spindle in proper working condition when it is returned to the customer.
Unfortunately, while support programs like these are commonplace in most industries, they are rare in the spindle repair business.

Summer Recommendations to Extend the Life of Your Spindle
Summer Can Mean Stress for Your Spindle
Summer is almost here and Northland Tool & Electronics would like to bring a few things to your attention that can help extend the life of your spindles during this season.
Check your air dryers:
The increased humidity puts higher demands on your air systems, leading to the potential of water getting to your spindle bearings (in oil/air applications). It is much easier and cheaper to address it now with an air dryer than later with a spindle repair.
Vacations:
This is a common time for employees to leave for weeks at a time.
