Pneumatic Self-Feeding Automation Controls
Automation adds versatility to a system. Many control options are
available. Some of our standard pneumatic controls are:
-
Cycle Automation - This is the least complex drill control. The system
consists of a "Start" operator to initiate the cycle and a limit switch mounted
on the drill to signal the end of stroke. The limit switch signal sends
the tool back to its' retracted position. This cycle will repeat
with each "Start" signal. Options are available to start the cycle
from a remote source, such as a PLC or to receive a start signal from an
upstream operation.
-
Sequencing Control - Many applications are not a single step but require
a series of operations. Drill, chamfer and tap is a familiar multiple
step operation. Our Sequencing Control handles these multi-step operations.
-
Peck Drill Control - Deep hole drilling can have problems extracting chips.
These problems usually occur at Depth/Diameter ratios above 5/1.
This ratio is not uniform but varies widely with material type and
tooling. Drill-Unit has a basic pneumatic peck drill control based on
time cycles. The drill and retract time cycles are individually adjustable.
A typical drill cycle may be double the retract cycle since the return
can be rapid.
-
Clamp Control - Clamps may be necessary to contain the work for drilling.
This usually true for all drilling except vertical down operations. Our Clamp
Control integrates with our other controls to automatically sequence the
clamp closure, drill and open clamp operations.
-
Air Motor Control - Air motors should be integrated in the stroke control
to reduce air consumption. Our control automatically starts the air motor
anytime a drill cycle starts and stops it when the Drill-Unit returns to the
retracted position.
-
Signal kits are for integrating our system into a customer's control system.
A common situation is when the Drill-Unit is started from an upstream
signal and must return control signals to downstream equipment. We
offer factory mounted industrial rated limit switches for "proofing"
both stroke limits. Optional switches, such as inductive proximity
type, are available.
Options are available to customize a control for your project.
Some options are:
-
Foot Pedal Start/Operation
-
Two Hand Anti-Tiedown Safety Start
-
Remote Electric or PLC Start Signal Option
