Should you want to machine long bar components that need to be mounted through the centre hole of the table, this unit has a closed bore, with a location diameter of 30mm diameter by 12mm deep. You need to take account of the number of divisions you require to establish the overall width and suitability to mount this device. This device style may be an issue due to width of the unit, such as collision with machine doors with Y axis travel forward.
You should consider the Y axis travel of the machine and if there would be any interference between the guard of the rotary table and the doors of the machine, particularly when referencing the machine, as a lot of VMC machines reference with the Y axis travelling to the front of the machine, towards the operator.
This is an ideal design of product for any VMC machine or a multitude of other operational uses, particularly those with a good working envelope.
