Cnc precision optical machining base+rotary motor table
16x 12 CNC Precision Optical Machining system Base + Rotary Motor Table but no head.
* Optical Precision Base with CNC X, Y & Theta
* reservoir has sight gauge.
* 14" Rotary Table Integral DC Motor + Brakes
* Made by Moore Specialty Tool
* Had Barry Vibration Isolation SERVA-LEVL parts
* Bijur Spray Mist Coolant system included
* Cross slide hand pump lubricator
* DRC rotary encoders on X and Y
* Hiedenhain rotrary encoder on head
* PMI servo motor on head 83 volt 14.4 Amp 1000 Watt 300 rpm
* Triple ways for Y axis.
The base, X and Y axis and the Rotary Motor table look fine (we have run the rotary table). The head assembly is gone save for the mount and servo drive motor. Mist cooler and lube systems in place. No vertical travel and no laser components remain. Connector knocked off of y-axis rotary encoder. No control electronics of any sort came with it. SOLD for COMPONENTS AS_IS.
This precision optical rotary table is actually a large pancake type permanent magnet DC motor. It is designed for continous operation at moderate speed without loss of accuracy. It has dual air brakes (normally on)-one external and one internal. Additional details are at the end of this listing.
The X and Y Axis drives have little windows for viewing the scale but you can only turn them by hand by reaching your fingers up underneath to the coupling between the encoder and the motor. Not an easy task. Looks like there are small holes you could use a bar or nail in to rotate slightly by hand.
In transport, someone hit the X-axis encoder cable connection with the results shown above.
The scale below indicates about 16 inches of X axis travel. Y-Axis travel looks like about 12 inches.
The Y axis seems to have triple ways.
The image above shows parts that were stuffed in the head space. We assume they are related to whatever was the head.
The images below are inner details of the unusual optical rotary table integral motor. In the image below, the wires labeled 275 and 276 feed the DC power to the motor. The other wires and the board are related to sensing or encoding the motor rotational position (we assume).
In the image below you cans see the copper comutator bars (end view). The comutator is the diameter of the motor which is about 12 inches. Rubbing the comutator bars are brushes. Two shown are for plus and two for minus. The motor has 3 sets of these double brush units. To the extreme right of the brush unit, you can see the end of one of the permanent magnets.
This optical rotary table motor has 2 normally on brakes. One is internal and is deactivated by putting air to the hose fitting shown above. The other is external. It grips a ring just above the scale shown below. To release you supply air to the Bimba puck cylinder shown next. The brake caliper assembly bolts on where the two holes are shown in the image below.
The external brake rotor (as it were) goes in the slot just above the small rectangular part at the bottom of the image below.
The top plate approaches an inch thick and appears to be stainless or some similar heavy metal. Overall diameter is about 14.5 inches.
