ATC Door Assist Cylinder adjustments - Door opening
Front Flow Control
- this flow control is a “metering-out” type (labeled 6 on drawing 27563-1), it controls
the air exhausting from the front of the cylinder, it is used to adjust the speed of the door cylinder as it
extends and lifts the door up.
Initial adjustment
: close the flow control all the way**, mark the knob with a black marker to
establish a reference starting point, and then open it 2 full turns.
ATC Door Assist Cylinder adjustments - Door closing
Rear Flow Control - this flow control is a “metering-out” type (labeled 5 on Sheet 2 of drawing 27563-1),
it controls the air exhausting from the back of the cylinder, it is used to adjust the speed of the door
cylinder as it retracts and closes the door.*
Initial adjustment : close the flow control all the way**, mark the knob with a black marker to
establish a reference starting point, and then open it 3 full turns.
Door Close Flow Control
- In order to close the door in a relatively controlled manner, a second flow
control for controlling the air going into the cylinder is used; this flow control is commonly known as a
“metering –in” type (labeled 4 on drawing 27563-2).
Initial adjustment
: close the flow control all the way**, mark the knob with a black marker to
establish a reference starting point, then open it 3 full turns.
**Note: When closing the flow controls, you will not feel a hard stop when the control is completely closed,
but you will feel a noticeable change in resistance as you approach the closed position, please use
reasonable care and do not over tighten them.
5.9.8 Air/Oil Tool Change Cylinder
This is air-over-oil cylinder that is mounted at the top of the machine, behind the spindle. Its output line
carries high-pressure oil to a hydraulic cylinder built into the spindle, for clamping and unclamping tools.
The oil reservoir must be maintained at the correct oil level (see drawing 27563-2). See section 6.15 for
how to bleed this hydraulic system if air gets into it.
5.9.9 ATC Air Cylinder
This is the cylinder that moves the ATC to the front and back when changing tools. This cylinder has two
adjustable internal cushions designed to decelerate the carriage motion smoothly, as it approaches each
end of its stroke. Cushion adjustment screws are located in the front and back end cap of the cylinder next
to the air line connections.
