The number of axes your press brake needs depends on the parts you want to bend. As for a torsion bar press brake, it will have a minimum of 2 axes. There will be Y axis for the ram position and one X axis for the back gauge.
Customers who want to improve the positioning efficiency cannot start from the hardware itself, but should consider more reasonable design schemes.
The bending process is the last and most important process in the forming of most parts (apart from the welding process) and the bending process directly affects the final size and appearance of the product.
