Inspection procedure 

Lathe Spindle Inspection 

Inspect the lathe spindle itself first before inspecting the chuck runout. The runout of 

the chuck could be caused a misaligned spindle.  

 

Note: 

The tolerances specified below is only applicable to NOVA lathes. Lathes from other 

manufacturers may have different tolerance standards therefore it is the best to 

contact the lathe manufacturer to confirm the spindle tolerances. 

Test 

Number 

Method 

Image 

1. 

Measure the radial runout of 

the spindle itself by: 

Locate the DTI on the register 

part of the spindle as shown on 

the image 

Spin the lathe by hand 

 

The runout measurement 

should be ranging between:  

-0.02mm ~ +0.02mm  

(-0.00079” ~ +0.00079in) 

Any reading exceeding this 

value will be exceeding the 

standard tolerances.
