Mill has been used to make some light work. Now my carbide mills and drills gets exercise at top speed (all that mill has, my 1,5 metric ton mill has 700 rpm max spindle speed....).
However, it started ocassionally really rough - banging and shuddering. As if the centrifugal switch went to very rapid ON/OFF switching during the start. Seemed to happen mostly on two highest speed (that I used anyways 80% of time).
Sent message to Warco and it was answered pretty fast. However they were not interested to assist me to troubleshoot it (maybe understandably - there are all sorts of people). Suggestion to take it to motor shops does to fly with me.
I opened the motor junction box and Z-circuit wires were all loose - that goes long way explaing the rough start (this is the start capacitor - centrifugal switch circuit), two other screws were not tighten either. Two other connections and ground wire connections were loose on the control box (the one with all push-buttons). After tightening them up it hasn’t been acting up anymore.
Next challenge is to find correct belts to it. The original V-belts are pretty lumpy and are wearing rapidly.
There are two belts, luckily they have markings that make some sense. They are A-profile belts and first number is ID-length, next is nominal length - in this case datum length.
Longer belt, markings on the belt: A-1000Li 1033Ld
Measured Li 998 mm, La 1058 mm.
Shorter belt, markings on the belt: A-838Li 871Ld
Measured Li 837 mm, La 897 mm
I would like to replace them with AX or XPA cogged belts. Looks like they are not made exactly to same dimensions, considering XPA 882 and XPA 1030 Optibelt Super X-Power belts.
let's see,
