Motors are far too powerful.
1600 ox in on a 34 will have a hell of a load of detent torque to over come which in turn will slow the machine down.

Very common mistake in that bigger is better.

For the travels you are talking a 3 or 4 Nm type 23 will move far faster than the 1600 motors.
If you want to go fast get the highest voltage drivers you can, usually 80 volts and run them at 50v AC rectified and smoothed with a big cap to get about 72 volts DC out.
