Donotusepower-cuttingtoolsinthepresenceofammableliquidsandgases.
Do not let visitors or untrained personnel near tools that are in use.
Ensure all observers wear eye protection.
Keep proper footing at all times.
2.5 Area Equipment
Secure the pipe with clamps, vises, chains or straps.
Ensure that both sides of the pipe at the cut site is fully supported so that the pipe will not move
after the cut is completed. Long lengths of pipe may be under load and the separation of the
pipe can release pressure. This pressure can cause both sides of the pipe to move.
2.6 Tool Care
Keep tools in good operating condition. Sharp tool bits perform better and are safer than dull
tool bits.
Do not use damaged tools. Always check your tools for damage especially if a tool has
malfunctioned, been dropped or hit, check it for damage.
Before you start operating the equipment, do no-load tests and feed function checks.
2.7 Tool Use
Use the right tool and tool bit for the job. Contact Tri Tool to help with your application.
Keep the tool bits fully engaged in the tool bit holders. Loose bits are sharp and can cause cuts
or punctures.
Disconnect power supply during setup and maintenance. Use all ‘Stop’ or Shut off’ features
available when changing or adjusting tool bits, maintaining the tool, or when the tool is not in
use.
Remove adjusting keys and wrenches before applying power to the equipment. Check the tool
before turning it on to make sure that all keys and wrenches have been removed.
Do not force tools. Tools and tool bits function better and safer when used at the recommended
speeds.
Do not reach into rotating equipment.
Do not reach into the rotating head stock to remove chips, to make adjustments, or to check the
surfacenish.

3. GENERAL DESCRIPTION
The Model 306 Tube Squaring Machine is a lightweight, portable machine designed
forfacingandsquaring1.00”(25.4mm)to6.63”(168.3mm)outsidediametertubing
up to .25” (6.35mm) wall thickness. The Model 306 is available with an integral,
variable speed 110 VAC or 220 VAC electric drive motor. The Model 306 features
quick-change aluminum Saddle Sets (no tools required for installation) and a .001”
(.025mm) graduated feed dial. The precision inside diameter Saddles hold the tubing
round to accurately square and face the tubing with minimum to no burr. The machine
accepts its own torque through the Saddle Clamping System. The Cutting Head
allows installation up to three Tool Bits for squaring, beveling or special preps. A set
of transparent chip guards cover the machine’s top window openings and allow for
safe and clear line-of-sight vision to the workpiece during use and open access to the
Cutting Head to changing Tool Bits.

If the pipe end is not square to the pipe axis, the Tool Bit will contact only a small
segment of the pipe during each revolution.
To avoid Tool Bit damage, the feed rate should be very slow until the Tool Bit is
contacting the pipe continually during at least one revolution.
Continue rotating the Feed Knob clockwise until the end of the pipe is completely
machined.
CAUTION
CAUTION: Be careful not to let the Tool Bit(s) cut into the Saddles or the Saddle.

9. CUTTING SPEED AND FEED
Use200surfaceinchesperminute(5080surfacemillimetersperminute)for:
Stainless steels in general when no coolant is allowed, all heavy-wall tube
and some chrome/molybdenum steels.
Use 250 surface inches per minute (6350 surface millimeters per minute) for:
Mild steels and some thin-wall stainless steels when coolants are permitted
and applied.
Use 300 surface inches per minute (7620 surface millimeters per minute) for:
Aluminum and some thin-wall mild steel and tube with coolants.
BASIC FEED RECOMMENDATION
Use very light feed for initial beveling or until a continuous cut is established.
Thisisveryimportantforlongertoolbitlifewhencuttingthroughamecut
or out of square pipe ends.
Useadequatefeed,.003”(.08mm)to.006”(.15mm)perrevolutionthereafter,to
establish a continuous chip cut.
If the feed is too light, only light stringer chips will be removed.
If the feed is too heavy, the drive will start to overload and the chip will start
to have a rough or torn appearance.

Tool Bit
Hex Wrench
Set Screws
Cutting Edge
Stainless, which work hardens, must be worked with a heavy enough feed to
stayundertheworkhardenedsurface,.003"(.08mm)to.006"(.15mm)feed.
Never allow the Tool Bit to burnish the surface.
A good rule of thumb for calculation purposes is a .0025" (.064mm) thick chip per
revolution. Actual measurements wil show a pseudo thickness of .006" (.15mm)
unless a pin micrometer is used for measure.
One revolution of the feed handle advances the Cutting Head .100" (2.5mm).
