IMITATIONS
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).

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. A part with a diameter larger than the platter
diameter or 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.
The HRT210SHS Table was designed for lighter size parts which may require numerous tool changes and
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.
