Turning the machine on

  • Remove any vice handles or loose parallels from the machine before running the startup process.
  • Press the green Power On button. Follow the instructions that appear on the screen.

Warming up the machine

You must warm up the spindle before use. This will take about 20 minutes, and gives you plenty of time to prepare your raw material for cutting. The warm up process ensure the bearings are warm and coated in oil before they are put under heavy load, thus extending spindle life.

Not warming up the spindle appropriately will cause damage to the spindle bearings.

  • Press the LIST PROGRAM mode button and find the "15K Spindle Warmup" program.
  • Press the SELECT PROGRAM button to load it into active memory.
  • Press the MEM (Memory) mode button, then press Cycle Start

You may wish to flush the coolant through during the warmup cycle. To do this, simply press the COOLANT button.

If you wish to flush the through-spindle coolant, press the Feed Hold button then the AUX COOL button to start the auxiliary coolant pump. Once through-spindle coolant is running press Cycle Start to resume the warmup program.

Turning the machine off

Clean the inside of the machine enclosure using the washdown coolant hose. Turn the coolant tap on the spindle head off to prevent showering yourself in coolant. Wash all the chips into the chip pan at the base of the machine casting, especially if they are ferrous metal. Make sure you get trapped chips underneath the trunnion out and clear.

If there is a lot of material in the chip pan you should remove as much of it as you can into the designated chip bin. Do not use the normal general waste bin. Leave the machine as clean as you would like to find it. Get chips off of ledges, out from the T-slots, everywhere. Spray the coolant lightly around exposed metal surfaces - the water will evaporate and leave a protective film of soluble coolant oil.

  • Change to the empty tool pocket by changing to MDI mode, typing T200 and then pressing ATC FWD.
  • Bring the tool head to the operator door by pressing the second home button on the side of the control panel.
  • Spray a reasonable amount of WD-40 or light machine oil into the taper to prevent rust formation while the machine is sitting.
  • Press the E-Stop button to prevent the spindle from moving.
  • Using a clean paper towel wipe out the spindle liner to remove any excess WD-40 and coolant residue.
    Ensure the paper towel is clean and does not have abrasive waterjet grit or metal chips on it. You must not scratch or score the spindle taper.
  • Press the red Power Off button to turn off the machine.

Once the machine is turned off clean around the machine. Place fixtures and setup blocks back where they came from, throw paper towels away, hang tools back in the rack.
