Does anyone know the maximum part weight that can be placed on a HRT-210 rotary table? The table will be mounted in the vertical position and the part will be supported by a tail stock. Rotary axis will be aligned along the x-axis of the machine.

The limiting factor is how far from the axis centre line your are machining. And then it depends on if you are drilling (high z load off centre is bad) or using a end-mill. Start our with light cuts and watch the axis loads. Hope this is helpful.

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 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.

All the info That I have ....GOOD LUCK!!!

Thanks all for the info
