VF-1/2/3/4/5 - X-Axis Way Cover - Replacement - Introduction

This procedure tells you how to replace the X-Axis way cover. The new way cover attaches directly to the guide bars. This gives stronger support for the way cover.
Safety Notes
Caution: When you do maintenance or repair on CNC machines and their components, you must always follow basic safety precautions. This decreases the risk of injury and mechanical damage.

Do these steps before you do work in the machine or in the control cabinet:
  • Set the main circuit breaker to the OFF position.
  • Use an approved lock with an approved safety tag. Always follow lock-out procedures in accordance to local government rules.
  • After turning off the machine, wait at least 5 minutes before working in the control cabinet, to allow power to dissipate. Wait for the voltage indicator LED on the vector drive to go off completely.
  • Always turn off the main air supply when you work on any part of the pneumatic system.
  • Make sure to rest the spindle head on a block of wood when work is done on a vertical axis. This will prevent any unintended movement that could result in the axis falling.
  • Never alter any safety circuits on the machine.
You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes. Serious damage to the machine components can result in costly repairs. The service technicians at your Haas Factory Outlet (HFO) have the training and experience, and are certified to do these tasks safely and correctly. The repair and service work performed by your HFO is protected with a limited warranty.
danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not fully understand. If you have any doubts about doing a procedure contact your Haas Factory Outlet (HFO) and schedule a service visit.

VF-1/2/3/4/5 - X-Axis Way Cover - Installation

Step 1

Make sure that the transition between the way cover guide bars [1] and the guide [2] in the casting is smooth.

If necessary, use a grinder to adjust the height or the width of the guide bars [3].

Step 2

Remove chips and debris from the linear guides.

Remove the used gasket or sealant [1] from the table mounting surface.

Clean the table mounting surface.

Apply a thin coat of Red-I grease to the way cover guide bars [2].

Step 3

Install the way cover over the guide bars.

Attach the way cover end panel to the way cover guide bars with the (2) screws [3].

Move the table to the full X-Axis travel [1].

Fully extend the sections of the way cover [2] to make sure the way cover moves correctly and is the correct length.

Lightly spray a multi-purpose lubricant onto the tops and sides of each of the new way cover panels.

Step 4

Move the largest section of the way cover away from the table.

Put RTV 598 BLACK SILICONE on the way cover where it touches the table mounting surface [1].

Put a small amount of black silicone on the horizontal seam between the way cover and the table [2].

Attach the way cover to the table with the (8) screws [3].

Remove any silicone that is squeezed out of the space between the way cover and the table.

Push POWER ON.

Check the X-Axis movement to make sure the way cover does not bind.
