CNC'ing a Mini Mill

Am converting a Chinese MiniMill circa 250KG, with round column on Z. Plan is to convert the X (stroke 405mm) and Y (Stroke 200mm) first. End use would be on plastic, wood, al alloy, brass and mild steel. My "max cutting conditions" would be 2 flute HSS end mill 25mm dia at 750mm per min with a 2mm depth of cut, what would be the load generated?

Have some new bipolar stepper motors Sanyo Denki 103 H8223-5011, Nema 34, 200 steps, 7.2 V, 2 A/ph, 3.6 ohms/ph, inductance 32.5mH/ph, holding torque 6.85 Nm, which hopefully i can use. With the lead screws being T24-2.5mm and the motor hooked direct (1:1) the theoritical resolution will be 0.0125mm / step.

My targets are cutting at 750mm/min which when hooked up directly (1:1) would be 1000pps with a torque value of 4.6 Nm from data sheet and for rapids 2250mm/min equates to 3000pps and torque value of 1.4Nm.

Am a little worried that the high inductance will slow the reaction of the control process. The machine will be mainly for 2.5d machining of typical mechanical items, so this may not be a really critical issue?

Would really like to hear of the experiences of others!!

TIA
