27 Maintenance (Clone)

The following sections provide guidelines for the correct maintenance of SYIL X and T Series machines.

To prevent hazardous conditions that can result in injury or equipment damage, ensure that the equipment and personnel at your worksite fully satisfy these requirements.

For some procedures, to be performed, specialist tooling may be required. Contact Technical Support for advice as needed.

27.1 Lockout – Tagout

Always follow your company lockout tagout procedure in addition to the instruction given here

27.1.1 Lockout procedures and indicators

The mains isolator switch is designed to be locked out with a padlock when doing the lockout. Use a 5 mm

diameter padlock.

To prevent the possibility of accidental startup and the sudden release of accumulated energy, put the SYIL into lockout before beginning inspection and maintenance work.

During lockout, post signs to indicate the machine’s service status and prevent unauthorized personnel from accessing its main energy isolation facilities. In addition, paste labels over the closure of the electrical cabinet in such a way that opening it requires breaking or tearing them, thus indicating whether any attempt has been made to activate the equipment during lockout.

27.2 Lubrication

It is critical that the machine rolling and sliding elements remain lubricated. Failure of the lubrication system can lead to rapid damage to costly elements such as ballscrews, linear rails and sliders.

The automatic oiler is set on a timer controlled by the PLC ladder of the controller. Parameters within the service level of the controllers dictate the interval at which the oiler will run and for how long each burst is.

Always ensure the correct grade of lubricant is used in the automatic lubrication pump as indicated on the sticker above the oiler.

It is recommended that an ISO 32 grade oil is used rather than any heavier oils.

The Automatic Tool Changer, lubrication of the two roller runners is key. Use waterproof grease on the bearings and the runners.

27.5 Resetting the Home Position of Axes

All SYIL CNC machines work with absolute position servo motor, negating the need for home switches. This means that if during installation or maintenance, if the servo motors of the axes are disconnected either electrically, from the cables, or mechanically from the mounts and ballscrews, their absolute position must be reset.

This process writes the absolute encoder position to the controller such that the rotational position of the servo motor corresponds correctly to the linear location of the axis it is connected to.

The X, Y and Z axis follow the same process, while the spindle orientation, (Referred to in other service bulletins as setting the ORI position), is different.

As the Z axis is also responsible for actuating the tool changer, a separate set of steps is required for resetting the actual position of the Z axis prior to resetting the home position.

27.5.1 Finding the physical locations of Home

The Home position of each axis corresponds to a physical location along the axes of travel. It can help to remove the protective covers of the X and Y axis when attempting to reset them.

X5

The location of the X and Y Home are when the table casting is positioned at 370mm from the left enclosure wall and 370mm from the rear enclosure wall as shown in Figure 92.

X7

The location of the X and Y Home are when the table casting is positioned at 210 mm from the left enclosure wall and 335 mm from the rear enclosure wall as shown in Figure 125.

Figure 125: Location of Home in the X and Y directions - drawing

27.5.2 Finding the physical locations of Z axis home

The Z axis home location is the same achieved when the tool change mechanism grabs/catches a tool. Resetting the Z axis home is best done using a Tool Changer Alignment tool as shown in Figure 93

Assemble the alignment tool and manually install it into the spindle and tool changer.

When Z home is achieved, there will be 0.03-0.05 mm gap between the taper and the flange portions of the alignment tool as shown in Figure 94

(a) Arm type tool changer

For the arm type tool changer equipped machines, the Z home location corresponds to the Z height at which a tool change occurs.

WARNING

Because of the inherent risk involved while setting up the tool change height, contact Technical Support

(b) Umbrella type tool changer

For umbrella type tool changer equipped machines, the Z home location is 90 mm above the Z height at which a tool change occurs.

27.7Recovering after a Crash

It is not uncommon for new as well as experienced users to miscalculate tool lengths or mistakenly declare WCS coordinates resulting in the machine violently ramming into the workpiece.

To protect the machine, torque limits have been defined in the Controller and Drivers such that the machine will error in the event of a crash. In the event of a very violent crash, it is possible that the ballscrew to motor coupling may slip resulting in the apparent machine coordinates not corresponding to those set by the factory.

In this case, it is very important to establish if the machine has lost its absolute positions. The implications are that the machine may hit hard stops on any of the axis travels before the soft limits become active. In the case of the Z axis, the tool change position may be incorrect in space and an result in further errors or damage if not corrected.

NOTE: Set the home positions of the axes that require resetting. The following instruction describe the required steps to recover the absolute positions of each axis.

27.8.2 Battery replacement procedure

The process is common on both the LNC M6800 and the SYNTEC 22MA systems.

The power to the controller must be switched on while the batteries are being replaced as there is otherwise no means for the drivers to maintain their memory.

  1. Switch the machine power on and start the controller
  2. When the controller has booted up completely, press the E-Stop button
  3. Locate the battery needing replacement
  4. Unscrew or unclip and remove the battery housing cover
  5. Remove and dispose of the spent battery
  6. Insert new batteries of the same specs with the correct polarities
  7. Refit the cover
