CNC Router – Maintenance Procedures

Resurfacing the Spoilboard

The spoilboard on top of the vacuum bed becomes scarred through use and eventually the resulting leakage reduces the effectiveness of the suction.  Once this point is reached, the spoilboard can be milled down 0.015 inches to recover a clean flat surface.  The following procedure is only to be performed by management staff:

  1. Locate the spoilboard cutter tool in the drawers, Onsrud 91-102.  Install it in a collet in tool holder 8.
  2. Turn on the dust collector.  Verify that the bed is clear.
  3. Click RESURFACE on the interface to start the process.
  4. Press Enter to confirm, then double-check that the vacuum table comes on.
  5. The router will pick and measure T8, then cut the whole surface at Z=-0.015″.
  6. It will then store the tool and run a vacuum sweeping pass.
  7. Remove the spoilboard cutter and store in the drawer.
  8. Turn on the vacuum bed, then  pick and measure a milling tool (e.g. T3, MEASURE).
  9. Slowly jog to Z=-0.015 inches.  Verify this is the new table height.
  10. Click RECALIBRATE Z to set the new Z=0 height.

After many cycles the spoilboard will need to be completely replaced.  It is probably thick MDF (e.g. 3/4″) surfaced on both sides to increase porosity.

Cleaning and Lubrication

The following guide documents periodic procedures for cleaning and lubricating the router. These should be performed only by trained staff. Use of the IDeATe CNC Router is restricted to approved users; this guide is not a substitute for training and certification.

Following the maintenance schedule described in this section will increase the life of your machine and reduce downtime due to breakdown or malfunction. These are guidelines only. These guidelines assume that the machine is being operated approximately 40 hours per week.

Main Power and Circuit Breakers to the Machine MUST Be Turned Off during Maintenance Operations.

To be performed as required:

  1. Empty dust collector.
  2. The gear rack drive system on the 1000 & 950 series Machine has an oil/air mixture blow off tube at the pinion gear. Make sure that a proper flow is maintained to insure the gear rack is kept clear of material. Check rack for particles that may have become lodged in the teeth and remove with a stiff brush.
  3. Blow out and clean the intake filters on the pressurized electronics box and computer control cabinet. Dirty air filters will reduce the flow of air to the components in the cabinet and may shorten their useful life.
  4. Most high speed Routers come with sealed bearing and require no lubrication for maintenance. For routers that require lubrication refer to the manufacturers maintenance guide for details. Routers with brushes should be checked for wear and rotated 180 degrees to insure proper operation and longer life. Cooling fans should be kept clean and clear of obstruction. Periodic checks to confirm proper calibration and orientation of your router to the work surface should be performed if the router runs into fixturing or any other obstructions by mistake.
  5. Ensure that the air filter in the optional regenerative blower or vacuum pump remains clean.


  1. Clean and wipe down the machine while making a visual inspection. This will allow the operator to become familiar with the mechanics while maintaining the machine.
  2. Check the oil level in both bearing oiler lubricators. The oil is a light 10 weight air tool oil.
  3. Back up all your programs and files.


  1. Remove the end plates on the two Y Axis transmission boxes. Using compressed air blow out any dust and debris. You must wear eye protection during this operation.
  2. Check all timing belts for adequate tension and wear. The belts should be tight but not so tight that it takes extreme pressure to achieve deflection.
  3. Check Belt tension on all axis
