Cleaning the Machine

Interval

1 Year(s) Real time

Reduce this interval depending on the contamination of the machine.

Component

Machine with all units and fittings

Recommended cleaning agents:

  • Water-soluble cleaning concentrate which dissolves grease, diluted for basic cleaning and undiluted for heavily contaminated areas.
  • For protective screens and screens: Glass cleaner.

The cleaning agent must have the following properties:

  • No explosive mixtures must be allowed to form.
  • They must not attack any of the machine elements, e.g. cables, connectors, seals, hose lines, plastic, paint, screens.
  • Use products that least affect health and environment.

Other aids:

  • Chip hook, broom, sweeping sheet
  • Cloths, sponges, window leather
  • Oil extractor

The following are not permissible:

  • Compressed air and waste steam fixtures. These aids damage guideways and other machine components.
  • Aggressive and scouring agents. These can attack plastic components, protective screens, screens and paint.

Cleaning agents may contaminate the cooling lubricant. Take the following precautions:

  • Before cleaning:
    • Completely evacuate chips and circulating cooling lubricant.
    • Ensure that cleaning agent cannot enter the cooling lubricant supply.
  • After cleaning: Completely remove cleaning agent collected in the machine bed, in the collection pans of attached components and in the drain channels before restarting up the machine.

Used oil, grease and cooling lubricants, contaminated cleaning solutions and contaminated cloths should be regarded as special waste and disposed of according to the locally applicable regulations.

Having made all machine areas accessible, take the opportunity to check all the fluid equipment. Proceed as follows to avoid doubling work:

Please observe chapter 4.2 "Special safety measures" when entering or leaving the machine. Danger to life within the traversing range of the gantry loader. Before climbing onto the machine, always move the portal loader to its parking position, switch off and secure to prevent it being switched on again. Do not remove gantry loader padlock before end of work or before removing the ladder. Proceed with caution if a tool is placed in the tool spindle whilst you are working within the work area.

Step 1:

Adequate clearance in the machine. Remove the bulky workpieces and clamping fixtures.

Step 2:

Traverse Z-axis (rotary table) to center of travel.

Step 3:

A tool is inserted into the tool spindle to prevent the ingress of dirt.

Step 4:

Machining unit traversed into support position.

Step 5:

Tool change door opened using the individual function.

Step 6:

Loading hatch closed.

Step 7:

Gantry loader in parking position, switched off and secured against being switched on again.

Step 8:

All safety doors open and secured to prevent closing.

Step 9:

Electrically protected doors, if available, open and secured to prevent closing.

Step 10:

Machine switched off at main switch and secured against being switched on again.

Step 11:

Compressed air shut-off valve closed and secured to prevent opening.

Step 12:

Maintenance openings open.

Step 13:

Machining unit protected from falling by supports.

Step 14:

Secure tool change door to prevent it from falling.

Step 15:

Remove chips from the entire machine area using a broom or chip hook.

Step 16:

Check all housings with oil filling for escaping oil.

  • Depending on the machine version, pay particular attention to the following components:
    • Rotary table lower part
    • Gear motors
    • Gear unit of machining unit
  • If components are not sealed, repair damage yourself or have it repaired by Customer Services. Do not operate machine with damaged equipment!

Step 17:

Check all fluid equipment components for leakages and visible external damage.

For procedure, see: "Inspection of fluid equipment"

Step 18:

Clean entire machine using cleaning solution.

Step 19:

Rub dry blank, metallic surfaces and lightly rub with lubrication oil.

Step 20:

On machines with "oil pan" option:

  • Exhaust and rub out the oil pan.
  • Check oil pan for leaks.

Step 21:

Clean vision panels and screens using window cleaning agent.
