OEM repaired parts

UVA LIDKÖPING has always focused on high quality and reliability on our grinding Machines.

In this respect, the grinding spindle is one of the most critical components. UVA EU High Frequency Grinding spindles are specially designed for demanding bore and seat grinding operations where optimum precision at high production rates is expected. Because the grinding spindle is the heart of the machine, UVA LIDKÖPING recommends an OEM repair so that the UVA grinder will continue to deliver the same quality and productivity as when the machine was new.

When the UVA parts such as spindles need service, they are sent to the same precision assembly shop at our factory in Sweden that originally built the part. Here, UVA LIDKÖPING’s specialists have both the knowledge and the special equipment needed to return your UVA spindle to the same performance level as when it was new. The highlights for a UVA spindle repair procedures are outlined below.

Spindle Bearings

The bearings are the most critical for the performance of our spindles. UVA LIDKÖPING purchases bearings in batches in order to control quality. Due to the extreme demands on spindles, we have sometimes found that even bearings that meet the manufacturers’ strictest standards will fail prematurely in service. UVA LIDKÖPING tests all new and repaired spindles as described below to prevent such failures. If an excessive number of bearing fail these tests, the entire batch is rejected and returned to the manufacturer.

The following procedure applies to bearing replacement, and other repairs to the spindle:

1. UVA spindles are equipped with ultra-precision or ABEC9 hybrid angular contact bearings.

2. The specified bearing preload is achieved by a spring pulling the inner bearing housing into the spindle.

3. Rotors are balanced separately to maximum 2mm/sec vibration level. If necessary, the rotors are balanced again to the same level when the spindle is assembled.

4. After spindle assembly, the nose run-out and taper is inspected with specially designed UVA LIDKÖPING gages and tooling.
