PERATION

Use the steady rest manufacturer’s operation manual for additional steady rest alignment instructions.

Notes for proper operation: 

Do not exceed the recommended maximum pressure for the steady rest.

Check all bolts that secure the steady rest to the platform. Ensure they are torqued properly.
1/2 -13 110 ft-lb. 

 

5/8-11 180 ft-lb.

Keep your hands, loose clothing, tools, etc. away from the steady rest as it closes.

The workpiece must have a smooth, concentric diameter in order to clamp it properly. Do not put rough 
material in the steady rest jaws.

Warning

If using the tailstock be aware of the current position of the steady rest 

platform, a collision could occur.

Types of Rollers

Different rollers can be used in the steady rest unit. There are two types of rollers, crowned and straight. 
Straight rollers are used on standard cylindrical parts and crowned rollers are used on tapered work pieces.

AILSTOCK

Mount the steady rest on the platform and snug the mounting bolts. Clamp the workpiece in the chuck and the 
steady rest.

NOTE:

  The hydraulic pressure to the steady rest is adjusted using the pressure regulator 

on the left side of the lathe.

Place a dial indicator on the turret and position the tip on the diameter of the part. Rotate the work piece by 
hand and check for defl ection of the part, defl ection should not exceed .001”. 

NOTE:

  Check the pressure to the steady rest. Incorrect pressure routed to the head can 

cause defl ection in the part.

Correct any defl ection and tighten the steady rest mounting bolts.

Open and close the steady rest and check for defl ection again.

NOTE:

  If the pressure to the steady rest unit is changed, the previous steps should be 

repeated to verify the part is turning true.

Part accuracy will suffer if the steady rest head is not aligned properly. The misalignment will cause the mate-
rial to not turn true and can lead to the part being thrown from the chuck.

ROGRAMMING

M Codes

M Codes are used to automatically open and close the steady rest.
 

M59 P1155 to clamp

 

M69 P1155 to unclamp

NOTE:

   If the M code commanded is the reverse of what is described, the hydraulic lines 

are installed incorrectly. Swap the positions of the hydraulic hoses at the steady 
rest head.
