The PATH-Series is an entry-level tube honing machine. Precision sizing and finishing of
long and large bores has never been easier and more productive.
The field-proven features of the PATH-series include:
Available in customized lengths. Lengths start at 6 feet.
Optional Sunnen MPS feed system.
V-type fixturing. It provides an economical way to hold a variety of part
diameters.
CENTER
FEATURES THAT MAKE THE PATH-SERIES IDEAL FOR SIZING AND
FINISHING BIG BORES
Spindle Load Meter For Peak Efficiency:
Built-in load meter indicates high and low spots in the tube bore. Operator can adjust the
stroke as required for optimum cycle time.
“Blind Hole” Capabilities:
Work out tight spots in the bore when using the short stroke cycle and stroke dwell
features.
Adjustable Work holding Fixture:
Accurately position and securely hold a wide variety of work pieces with the adjustable
work-holding fixture.
Optional Compensating Stone Feed:
The Sunnen Modular Honing Tool System continually compensates for stock removal
and stone wear. This keeps the operation running at peak efficiency at all times.
Variable Speed Drive Unit:
The perfect spindle speed for most honing jobs is quickly set by means of the variable
speed spindle drive unit.
Easy-To-Set Stroke Stops:
This feature makes set-up quick and easy. The tool can be short-stroked at any point
within the stroke using the manual override (ideal for honing blind bores or work pieces
with localized tight spots).
The stroke speed can be controlled to allow the operator to hone rough bores at slow
speeds on the first pass.
Stroke Range, Capability And Speed: 72"
End Stroke:
Short stroking is activated with a touch of the joystick. This is ideal for working on
“barrel” shaped holes and “blind” holes.
Dwell Feature And Manual Reversal:
The touch of a button allows the operator to dwell the stroke at either end of the work
piece. Manual reversal of the stroke can take place anywhere in the work piece.
Honing Cycle Times:
Times can be increase or decreased with the use of a mechanical timer.
Modular Honing Tool System:
Several different tooling systems are available depending on the specific application.
Standard components include a remote feed unit and controls at the operator’s station.
