Rotor Turning Machine With Two Cutter Three Servo Motor For Boostrite Rotor WIND-3A-PL

Q & A

1.Cycle time:The cycle time will be around 60 seconds - 4 passes for turned 0.77mm with lamination

2.For CPK study,

  How many pieces do you need to check rotor lamination OD and total run-out on machine to run continously before delivery for each model?

  Regarding the qty for the CPK study , I will send you 50 pieces of 1 model

Here is the CPK analysis using your data and as you can see the result is good, CPK > 1.33

(1) Competitive Advantages of three axis servo device turning machining machine

1.Precise with three axis servo device control 

2. Smallest commutator handled by lathed commutator precise turning machine :

   Turned window lifter small armature commutator OD 7mm, Shaft OD 3.0mm

3. This turning machine can work with two cutters if required for different turning direction

4. The turning tool is diamond material, also the tool holders and inserts can be custom made

     for lathing special material other than copper, aluminum 

(2) Configuration of the commutator turning machine

Z Axis Mitsubishi Servo system (Turning length)

X Axis Mitsubishi Servo system (Turning depth)

Y Axis Mitsubishi Servo system (Press Arm)
