GENERAL
This section gives step-by-step setup and operating
procedures for Sunnen
®
Vertical Honing Machine.
SAFETY PRECAUTIONS
The following precautions should be observed to
ensure maximum safety while working on or around
your Machine.
• Wear proper Safety Items (such as safety glasses
and other personal safety equipment as necessary or
required).
• DO NOT wear loose fitting clothes or jewelry
while working on or around Machine.
• Keep area around Machine free of paper, oil, water
and other debris at all times.
• Keep Machine and area around machine cleaned
of excessive lubricant and lubricant spills.
• Keep tools and other foreign objects clear of
Machine while in operation.
• Keep tools clean and in their proper storage
compartments to maintain them in proper working
condition and to prolong tool life.
• Inspect Tools before using. Check for cracks, burrs
or bent parts that might effect operation.
• DO NOT force tools when operating. Tools will do
a better and safer job when operated at the rate for
which they were designed.
• Turn OFF electrical power when performing service
on your machine, which does not require power.
• Disconnect Machine from main power supply and
allow drives to drain before any work is performed
inside of Electrical Enclosure.
• Ensure all Guards are in place and are in proper
working order.
• DO NOT override safety switches or lockouts.
Where interlocking systems rely on special
actuators or keys, DO NOT keep spare/master
actuators or keys on, around or near machine.
• Use proper lifting procedures when loading and
unloading the Machine.
• Keep all non-essential persons clear of work area.
Visitors, especially children, should not be permitted
near the work area.
• DO NOT use machine for other than its intended
use. Using these Machines for other purposes could
result in damage to machine and loss of warranty.
• Be sure to work in a well lit area and to use light
supplied to avoid dangerous unseen conditions
which may exist otherwise.
• Use ONLY factory authorized or recommended parts
or replacement accessories. Using parts or accessories
other than those approved by Sunnen could result in
damage to machine and loss of warranty.
• Electrostatic discharge can damage the circuitry of the
electronic components used in this Machine. Use proper
electrostatic controls when working with or around
electronic components. Ground Machine and use wrist
strap to reduce the chances of static discharge.
• Residual Voltage exists for 2-3 minutes after
Master ON/OFF Switch is turned OFF. Before
working inside Enclosure, wait for all fans to stop
running to allow drives to drain.
OPERATING TIPS
If load meter is indicating loads of over 95% consistently,
reduce spindle speed. If lowest speed is being used,
increase feed rate to break down stone, or use a softer
stone. Also verify that “Rapid Until Load” is set
correctly by reviewing Load graph and observing
trend. Remember, if starting load is higher than steady
state operating load, result is stone wear without
corresponding stock removal.
If honing technique above does not result in greater
stone life, use a lower feed rate setting.
If a low operating load accompanies poor stone life,
increase spindle speed or use a harder grade stone.
If stock removal rates are too low:
Increase stroking rate.
Use a higher feed rate.
Use a coarser stone.
Use a harder stone.
If bore is tapered, remove taper by using the dwell
feature activated by pushing BLUE dwell button. You
can push this button while machine is honing. On RUN
screen (inside Bore Profile), there are five marks in
middle of screen that represent five locations in bore
