Step 3: Filling the Machine with New Coolant

Procedure
  1. Attach the drain cap to the coolant tank.

  2. Place the collection tray () into the coolant tank.

    The side of the collection tray with the hole faces the front (the side where the coolant cap is). Move it toward the front and place it in the center in the left-right direction.

  4. Adjust the coolant.

    To make the coolant, mix the 3 materials (water, additive (ZAW-1000D), and chelating reagent (ZCH-250D)) at the fixed ratios. Use the included measuring cup for measuring.

    1. Water: Mix water and additive in the ratio of "95:5" (water:additive).

      There is no need to stir the solution.

      The capacity of the coolant tank is approximately 5 L. To fill the tank, use 4,750 ml of water and 250 ml of additive.

    2. Water + additive solution: Mix the water + additive solution and chelating reagent in the ratio of "400:1" (water + additive solution:chelating reagent).

      There is no need to stir the solution.

      To fill the tank, use 5,000 ml of water and additive, and 12.5 ml of chelating reagent.

      CAUTION

      Be sure to use the specified additive.

      Additives are effective in reducing coolant deterioration and raising the milling efficiency in order to maintain product performance. Furthermore, if additives are not used, the coolant may generate an unpleasant odor.

      CAUTION

      Be sure to use the specified chelating reagent.

      The chelating reagent works to make calcium and similar substances contained in the water inactive, making it easier to clean off milling powder that adheres to the machine and the cutting tool after milling.

      Refer to the appropriate safety data sheet (SDS) for the chemical substances used in the additive and chelating reagent and the safety related to those substances.

      To purchase additives, contact your authorized DGSHAPE Corporation dealer or access our website (https://www.dgshape.com/).

      IMPORTANT

      Add an additional 12.5 ml of chelating reagent to the coolant in the following cases.

      • It is easy for milling waste to adhere to the inside of the machine.
      • The milling time exceeds 8 hours, regardless of whether milling waste adheres to the machine.
  5. Fill the coolant tank with the coolant.

    Do not add coolant past "MAX" indicated on the coolant tank.
