7.2 Machine Operation

Step 1:

 Activate air supply to machine

 WaRninG

When air pressure is first applied to the machine, the boring head 
carriage may move. Do not stand behind the machine. 

NOTE: The air supply must be on to make certain adjustments and 
enable movement of the workpiece hold-down clamps and boring 
carriage.

Step 2:

 Turn on power to machine

Step 3:

 Ensure air pressure is correct

Step 4:

 Select operation mode 

There are two operation modes available on the DBR50 machine. 

Manual Mode (hand symbol): Use for manual setup of the machine.

Turn the knob to the left for manual control. The boring head 
carriage will move pneumatically into the desired position without 
spindle rotation, unless spindle rotation is manually turned on.

Automatic Mode (circular arrows): Use for normal machine 
operation. 

Turn the knob to the right for automatic up/down movement 
of the boring head carriages. The foot pedal activates the 
pneumatic movement of both the boring head carriages and the 
work hold-down clamp. The drill spindles will run automatically 
when the boring head carriages move up and stop when they are 
in a lowered position.

Step 5:

 Set boring depth

Attach the crank handle to the left or right digital readout to set 
the boring depth for the back and front carriages. The depths are 
displayed in millimeters (mm) on the integral digital readouts for both 
controls. 

To adjust:

1.  Turn the crank handle to change position of boring depth, 

observing position on digital readout. 

Step 6:

 Position rear boring head

The rear boring head can be adjusted to change the spacing 
between the front and rear boring heads by using the center digital 
readout.

To adjust:

1.  Turn the crank handle to change position of the rear boring 

head, observing position on the digital readout. 

Step 7:

 Position the workpiece hold-down clamps

Hold-down clamps

Position the hold-down clamps according to the dimensions of your 
workpiece to securely hold it in place while boring.

To accommodate workpiece thickness:

1.  Place the workpiece on the table under the hold-down clamps.

2.  Lower the hold-down clamps to within an inch of the surface of 

the workpiece.

3.  Lock the hold-down clamps in place.

To accommodate workpiece width:

1.  Loosen the lock lever for each hold-down to be adjusted.

2.  Move the hold-down(s) right or left to the optimal position to 

secure your workpiece.

3.  Tighten the lock levers.

NOTE: A minimum of two workpiece hold-down clamps should 
always be used when possible.

To reposition the hold-down assembly:

1.  Loosen the lock levers at each end of the assembly.

2.  Move the assembly forward or back as needed.

3.  Tighten the lock levers.
