1.0 INTRODUCTION
The CPO-315 HFA-NF Fully Automatic Cold Saw is a high speed saw designed to cut solids, tubes, flats
and other profiles in grades of nonferrous material that range from aluminum, brass, copper, synthetics
and extrusions.
Cold sawing is a process similar to a milling process. In most cases, this gives a finished cut that does not
require any secondary machining or de-burring.
The high spindle speeds of this saw make it ideal for extrusions with varying cross section thicknesses.
To achieve the best results from this machine, choose the proper spindle speed. Proper material clamping
and a good quality coolant are also important.
Cold sawing has several advantages over band saws and abrasive saws. Besides the mill quality cut, cold
saws have the ability to generate faster cutoff times than band saws. There are no sparks and excessive
noises that are associated with abrasive cutoff saws. There is no work hardening of the workpiece.
The vise allows for easy change over to special clamping jaws for profiles and extrusions. Having two
spindle speeds enables the user to cut a wide range of materials.

programmed from the factory to count up. If you have an application that requires the counter to be set
to count down, please SEE SECTION 6.9. To set the counter for an operation, press the white buttons
until the number of pieces you want to cut is displayed on the bottom row of the counter. If you press a
number you do not want, continue pressing the button until it returns to zero and then, start over. The
machine will run in the automatic position until the top row of the counter reaches the same number as
the one you selected on the bottom row. The machine will also quit the automatic operation if the
machine runs out of material. The machine will not run in the automatic mode if there is not a quantity
set on the counter.
5.1N FEED RATE CONTROL
This valve controls the down feed rate of the saw head and is used in the set-up of the up and down
stroke control of the saw head. To adjust the down feed cutting rate of the head, turn the control all the
way to the right (clockwise) and then, open it one turn. The down feed rate is set by sound. Start with a
slow rate and gradually increase it until the blade chatters, then back it off slightly. Selecting the proper
blade and the condition of the blade will effect the down cutting rate dramatically.

6.1 BLADE INSTALLATION
SEE FIGURE 4 BELOW.
CAUTION: THIS MACHINE IS DESIGNED TO USE CARBIDE TIPPED BLADES, ONLY.
USE ONLY BLADES DESIGNED FOR THIS MACHINE. DO NOT USE BLADES DESIGNED
FOR THIS MACHINE ON ANY OTHER EQUIPMENT. THE MAXIMUM RPM’S FOR THESE
BLADES ARE 4,000.
FIGURE 4

Page 19
The CPO-315-HFA-NF saw is designed to use a maximum 12 inch (300mm) diameter blade.
The arbor size is 40mm with two 8mm pins spaced at 55mm.
BEFORE INSTALLING THE BLADE, make sure that the power to the machine is off.
USE THE FOLLOWING STEPS TO INSTALL A BLADE:
An 8mm hex key wrench (D), shipped with each machine, is required to change blades.
1. Raise the movable hood guard to the open position.
2. Release the upper stroke control stop (H) and allow the head to travel to its full up position.
3. Remove the blade bolt (B) and the blade flange (C).
NOTE: The blade bolt is left hand threaded and must be turned clockwise to remove it.
4. Check the blade flange, the blade and the saw spindle for any chips or nicks that will affect the
way the blade seats.
5. Install the blade. Make sure that the pin holes in the blade line up to the holes in the spindle.
6. Replace the blade flange (C) and start the bolt (B) into the spindle.
7. Before locking the blade in position, the back lash must be taken up. To take up the back lash,
rotate the bottom of the blade toward you until it seats against the drive pins.
CAUTION: THE BLADES ARE VERY SHARP AND CARE MUST BE TAKEN WHEN
REMOVING THE BACK LASH. DO NOT GRIP THE CUTTING EDGE OF THE BLADE
BARE HANDED. THE BACK LASH MUST BE TAKEN UP EVERY TIME A BLADE IS
CHANGED.
8. After taking up the back lash, tighten the blade bolt (B).
9. Reset the upper stroke control and return the movable hood guard to the down position.
10. Break in the saw blade. The teeth on new or re-sharpened blades have a very sharp edge and
should be fed through the first three or four cuts, very slowly, before starting normal cutting.
Besides taking up the back lash and breaking in the blade, it is very important to keep the blade
flange, the spindle and the blade clean and free from nicks. Failure to do these things will result in
broken or damaged blades.
