EVS Toolroom Lathe w/DRO

 If necessary in the following step, refer 

to Offsetting Tailstock on Page 44 for 
detailed instructions.

  Use calipers to measure both ends of the 

workpiece.

— If the test stock is thicker at the tailstock 

end, move the tailstock toward the front of 
the lathe

 the distance of the amount of 

taper (see Figure 47).

 Repeat 

Steps 6–8 until the desired accuracy 

is achieved.

Move the tailstock toward 

the front of the lathe ½ the 

distance of the taper.

— If the test stock is thinner at the tailstock 

end, move the tailstock toward the back of 
the lathe

taper (see Figure 48).

Move tailstock toward the 

back of the lathe ½ the 

distance of the taper.

Figure 49 shows the MT#5 dead centers 
included with the lathe. In addition, an MT#7–
MT#5 tapered spindle sleeve is included for 
mounting centers in the spindle.

A dead center is a one-piece center that does not 
rotate with the workpiece and is used to support 
long, slender workpieces 

Use the dead center in the spindle for operations 
where the workpiece rotates with the center and 
does not generate friction.

The carbide-tipped dead center can better 
withstand the effects of friction and is best 
used in the tailstock where the workpiece will 
rotate against it. The tip of the center must be 
generously lubricated during the operation to 
avoid premature wear and maximize smooth 
operation. Using low spindle speeds will also 
reduce the heat and wear from friction.
