1. INTRODUCTION
1.1 D ESCRIPTION
The HAAS rotary table is a fully automatic, programmable, rotary positioning device. The unit is made up of two
parts: the mechanical table that holds the workpiece and the electronic unit that controls the rotation of the
table. Positioning of the workpiece is accomplished by programming the angular movements into the memory
of the control and then pushing the CYCLE STARTbutton on the front panel.
The unit was specifically designed for rapid positioning of parts in secondary operations such as milling,
drilling, and tapping. The device is especially suited to automatic machines such as NC mills and automatic
productionmachines.Thecontrolcanberemotelyactivatedbyyourequipmentanddoesnotrequirehuman
assistance,resultinginfully automatic operation. Furthermore, one unit can be used on several different
machines, thereby eliminating the need for multiple units.
TABLE
The rotary table can be used in almost all of the applications where a manual rotary table can be used. Posi-
tioningofthetableisaccomplishedthroughadeep-toothengaging,self-lockingwormandwormgearset.The
worm is connected to aAC (DC) servo motor through a timing belt and pulley set. Odd number bolt circles and
unevenholespacingareeasilyhandledwithsimpleprogramming.Thetableisequippedwithapneumatic
brake (HRT450 uses air over oil).Aregular shop air line of approximately 100 PSI is all that is needed to
activatethebrake.
TheHRT210SHS(Super-HighSpeed)Table is unique from the other rotarytables.Ithasnowormgear set, belt,
or pulleys but uses a “Harmonic Drive” gear. It is directly driven by anAC servo motor and is 6 times faster than
ourstandardHRT210.
TheHRT320FBusesafacegear(Hirthcoupling)forextremeindexingaccuracyandrigidity.Itpositionsthe
platter in multiples of exactly 1° . The platter lifts .070” during indexing and the table positioning is done at full
rapid speed. The HRT320FB cannot be used as a full forth axis.
CONTROL

failure areas. This same software also checks out the computer system upon power-up, and alerts you to
component failures. Only one printed circuit board is used to control all major functions.
The optional RS-232 interface can be used to upload, download, enter data, read position, start, and stop motor
operation.

1.2 LIMITATIONS
The control and table are described as a “semi-fourth axis”. This means that the table cannot do simultaneous
interpolation with other axes. Linear moves or spirals can be generated by having an axis of your mill move at
the same time the rotary table moves (see the "Programming" section for details).
1.3 MACHINABLE P ART S IZE
The HRT series was designed for positioning and continuous milling of medium to large size parts. When
selecting a rotary table, the size of a typical workpiece and fixture must be considered and the size of the
rotary table should be matched to the expected loads.As a general rule, the diameter of the part should not
exceed the diameter of the rotary table platter.Also, the combined part and fixture weight should not exceed
the weight of the rotary table. However, these are only guidelines.Apart with a diameter larger than the platter
diameteror a long overhung and unsupported part might require that the weight be less than the weight of the
rotary table. Likewise, if the part is well supported (i.e. tailstock or pillow block), and the fixture and support
have less than 0.003" T.I.R, then the weight might be able to be more than the rotary table weight. Common
sense and good fixturing technique will generally make it possible to machine larger parts.
TheHRT210SHSTable wasdesignedforlightersizepartswhichmayrequirenumeroustoolchangesand
indexes, so the speed is important to reduce the cycle time. It has no brake, so this will also be a limiting
factor to the size of the part. Maximum part diameter is 8.00” and maximum part weight should not exceed 40
lbs.

1.8 HAAS T AILSTOCKS
Tailstocks must be properly aligned to the rotary table before using.
Clean bottom surface of tailstock casting before mounting to mill table. If there are any noticeable burrs or
nicks on the mounting surface, clean them with a deburring stone.
Seethe Haas tailstock manual (96-5000) for pneumatic tailstock’s operating pressure.
Tailstocks cannot be used with the HRT320FB table.
