*1 This micro-step controller was
developed by ACT. We guarantee no lost-step errors in
the normal operation. We have tested these machines at full speed (rapids rate) in
all axes continuously for many hours at a time; the motors did not get hot at all, nor was there any loss of position. There are 5 processors
in each controller: one for each of the three axes , one for the spindle motor control and
one for the coordination of all motions. The electronic system is thoroughly
tested subject to temperature variations and vibrations for reliability and lasting life.
Please see our "the technologies page." page in our website for details.
*2 Options to choose different size of motor with up to 50,000 RPM
maximum speed. Any off shelf small spindle can also be easily installed in the machine. We can provide the custom made fixture to secure any spindle user preferred on the machine.
*3 4th axis rotary table is a high
precision table with zero backlash, 7.2 arc sec (0.002 degree) resolution.
