Important: The warranty card should be filled out before you use the tailstock.
Important: When using Servo 5C Indexers, Haas Automation recommends using live center tailstocks only!
Note: Tailstocks cannot be used with the HRT320FB table.
Tailstocks must be properly aligned to the rotary table before using. Refer to page 5 for the alignment procedure.
To prepare the tailstock to mount on the table:
To align your tailstock:
To install or remove a Morse taper accessory:
To set up the HA2TS (HA5C):
1. Position the tailstock so that the tailstock quill is extended between 3/4" to 1-1/4".
This optimizes spindle rigidity (item [A]).
2. Tailstock to HA5C head alignment can be accomplished by pushing the tailstock (item[ B]) to one side of the T-slots prior to tightening the flange nuts to 50ft-lb. Precision locating pins mounted on the bottom of the tailstock allow for quick alignment, since the pins are parallel within 0.001" of the spindle bore. However, make sure both tailstock units are positioned to the same side of the T-slot. This alignment is all that is needed for the use of live centers.
3. Set the air regulator (item [C]) between, 5-40 psi., with a maximum 60 psi. It is recommended to use the lowest air pressure setting that provides the required rigidity for the part.
The operation of the tailstock is separated into manual and pneumatic types. Be sure the tailstock has been properly installed and aligned before operating.
To operate the manual tailstock:
NOTE: Excessive tailstock force, and misalignment greater than 0.003 Total Indicator Reading (TIR), causes premature wear on the geartrain and motor.
To operate the pneumatic tailstock:
|MODEL||NORMAL OPERATING RANGE||MAXIMUM AIR PRESSURE|
|Rotary Tables||10-60 psi (.7 - 4.1 bar)||100 psi (7 bar)|
|Servo 5C Indexers||5-40 psi (.3-2.7 bar)||60 psi (4.1 bar) for Live Centers only|
Maximum Air pressure = 100 psi (7 bar) results in 300 lb (136 kg) tailstock force.
Minimum Air pressure = 5 psi (.3 bar) results in 15 lb (6.8 kg) tailstock force.
Daily: Use a shop rag to thoroughly clean the unit free of chips and apply a rust preventative such as WD-40.
Weekly: Use a standard grease gun and apply 1 full stroke to the top mount zerk fitting, for a pneumatic tailstock.
Monthly: Use a standard grease gun and apply 1-2 full strokes to the top mount zerk fitting, for a manual tailstock.
Lubrication: Use MOBIL multipurpose grease with MOLY (Molybdenum disulfide) or equivalent.
