INSTALLATION

Always use proper Personal Protection Equipment when working with heads.  Follow lockout/tagout procedures when working on machinery

  1. Ensure proper spindle size before setting tool in place. Using a micrometer- with .0001” (0.0025mm) graduations- measure the spindle at the top, middle and bottom at 90-degree intervals. Nominal spindle size forAceCo heads is +0.0000″ I -0.0005″ (+O.OOOOmm / -0.0127mm).
  2. Cleantheinteriorofthecutterheadboreand spindle with a clean shop rag to prevent scarring either the spindle or the bore of the head during installation.
  3. For Ace-Loc heads: Once the head is carefully lowered onto the spindle, close the pressure relief valve and pressurize the head. Pump the tool up to the required pressure rating using a calibrated grease gun with a high temperature/high pressure grease (Chevron Delo EP NLGI 2 grease). The correct pressure value is engraved on the face of the sleeve. To reduce the chance of crashing the head, check the pressure of the head at least once per shift and more frequently when ambient temperature changes significantly throughout the day.
  4. Follow the machine manual recommendations for collet and straight bore spindle nut torque values.
  5. Install required safety lock collars for all Ace-Loc heads.
  6. Install all machine guards prior to energizing the

REMOVAL

  1. To remove an Ace-Loc head from a spindle, loosen the 3mm hex screw in the pressure relief valve. This will allow the grease to escape and depressurize the sleeve. Carefully remove the head from the machine spindle.
  2. Moulder and Planer Head Specific: Clean all gibs, knife pockets and knives with an evaporating solvent (Zep’s I.D. Red). Lubricate threads of gib screws with anti-seize lubricant (Loctite CS-A). CAUTION: Do not allow anti-seize to get on the knife or any mounting surfaces such as the gib, end of gib screws, pocket faces etc.
    Gib Screw Torque Value
    3/8-16″ 25-30 ft/lb (34-41n-m)
    M12x 1.75 30-35 ft/lb {34-47n-m)
    For other gib size, call for torque recommendations.
  3. Using a calibrated torque wrench, make sure all gib screws are tightened to the proper values and done in the proper sequence.
  4. Finger Joint Head Specific:Clean all knives, head surfaces and bolts with an evaporating solvent (Zep’s I.D. Red). After cleaning, balancing and reinstalling the knives, install the top plate and lubricate the threads of all the finger joint head bolts, nuts and washers with anti-seize lubricant. CAUTION: Do not allow anti-seize to get on the knife or any mounting surfaces.
  5. Using a calibrated torque wrench, make sure all finger joint head nuts are tightened in proper torqueing sequence. See AceCo technical section for proper finger joint head set up procedures.
