The description matches that of a tombstone, which is commonly used in horizontal spindle machines and allows for multiple workholding devices to be mounted on its vertical working surfaces. A manual collet fixture is a type of workholding device, but it does not consist of a tower with multiple vertical working surfaces. A pallet system involves the use of multiple pallets for efficient workpiece exchange, but it is not necessarily a tower with vertical working surfaces. A double vise is a workholding device that allows for two workpieces to be clamped at the same time, but it does not consist of a tower with multiple vertical working surfaces.
