Inspection Results:

• The upper spindle journal is scored. We recommend plating and grinding this area.
• The upper bearing housing is worn and scored. We recommend plating and grinding this area.
• 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 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.
