A bit of progress with the electronics cabinet for the lathe. Some components have been bolted to the back wall of the cabinet. From left to right: a Bonmet servo-drive for the main spindle servo, a Siemens VFD for the live-tool spindle motor, and to the right two Brushless PWM amps for the X and Z axis motors from pico-systems. Below these there are two 350W 48VDC switched-mode powersupplies. Today I made holes for two 220VAC 120 mm fans which blow air from both the left and right side into the cabinet directly on the heatsinks of the servo drives. There are plenty of holes in the bottom of the cabinet through which the air can exit.
