Inspection Results:

• The shaft will be replaced per customer request to have an ER32 collet.
• The upper bearing housing inner diameter is larger than design specifications and shows some wear. We recommend boring and bushing the housing.
• The lower bearing housing inner diameter meets design specifications and shows no appreciable wear. No modification is required.
• The upper and lower bearings show some wear on the inner and outer diameters.
• The stator failed the phase test and needs to be rewound.
• The fan is worn and will be replaced.
• The unit will be assembled and tested.

Inspection Results:

•The spindle journal diameters show no appreciable wear and are acceptable for proper bearing fits.

•The upper bearing housing inner diameter meets design specifications and shows no appreciable wear. No modification is required.

•The lower bearing housing inner diameter meets design specifications and shows no appreciable wear. No modification is required.

•The taper runout is acceptable. Our proposal provides no repair to the spindle taper.

•The upper and lower bearings show some wear on the inner and outer diameters.

•The tool pressure test checks fine.

•The stator passed the phase and insulation tests.

•The proximity switches work fine and will be set at time of assembly. The drawbar nut was loose causing the sensor not to read properly. We will replace (1) sensor.

•The unit will be assembled and tested.
