5. Maintenance Instructions
Important Note Regarding Operation:
The air motor is supported by two guide rods attached to the front plate of the deburring tool.
To prevent binding of the compliance, one of these guide rods is rigidly attached to the front
plate. The second guide rod and the compliance piston rods are free to float in the front plate.
This allows the motor assembly to achieve free compliant motion while resisting the motor’s
torque. DO NOT attempt to change the floating nature of the rods by adding washers or
additional thread locker. These actions will prevent the rods from floating, which will result in
binding of the tool’s compliance.
5.1 Routine Operational Maintenance
The VersaFinish is warranted by ATI for a period of one year or 2000 hours of operation
from date of purchase, whichever occurs first. The tool utilizes a vane-type air motor with
integral speed reduction gearbox. When subjected to normal use, this robust unit will
provide many hours of operation before service or repair is necessary. When subjected to
high shock loading or periods of continuous service without interruption, the unit will
require service or repair earlier. While simple in design, there are few user-serviceable
parts in the assembly. The user is encouraged to return the unit to ATI for service. The
following information is provided to assist the user when they choose to service the unit in
the field.
For all service, it is recommended that the air supply (before the solenoid valves) be
disconnected. Drain any trapped air pressure in the lines. It is suggested that the air supply
be ―locked out‖ to prevent accidental operation of the spindle. During maintenance
operations, refer to drawings in Section 7.
5.2 Media Replacement
The standard VersaFinish unit ships with a simple drill chuck to hold customer-supplied
media. A standard chuck key is used to loosen and tighten the chuck. When tightening the
chuck, insert and turn the key into each of the three holes around the chuck's perimeter.
ATI can design special media holders for custom applications upon request. It is assumed
that the customer requesting such special media holding devices will be familiar with their
use. When in doubt, the customer should refer to the manufacturer of the media to
determine how to properly secure that media to the spindle.
5.3 Boot Replacement
The tool is equipped with a simple boot between the moving motor mounting plate and the
main housing. This boot is provided to minimize contamination of the guide and piston rods
allowing free axial motion. This boot is not provided as a safety device. Under no
circumstances should the user operate the unit without the boot. The user should never
have their hands on or near the unit when in operation.
To replace the boot, perform the following steps.
1. Discharge any pressure in the air lines to the tool's spindle and compliance
connections.
2. Use a suitable pick or small ball-end hex wrench to lift and remove the o-ring securing
the boot to the front plate of the unit.
3. Similarly remove the o-ring securing the boot to the main housing.
CAUTION: The floating VersaFinish rods attached to the front plate must not
be restrained. Rigid mounting of the rods attached to the front plate will result
in binding of the tool’s axial compliance.
