4.6 DIGITAL ANGLE GAUGE

The digital angle gauge is easily installed against 

the machined surfaces on the mill head, and held in 

place by the magnetic surfaces on the edges of the 

angle gauge . The digital angle gauge allows for easy 

angle setting of the head

. 

(Fig.4.13)

Features and Functions

1.

Automatic LCD Backlight

2.  Can measure in absolute or relative measurement

3.  The angle will be displayed in degrees

4.  The working range of the angle measurement is 4  

x 90°

5.  Automatic digit inversion for overhead 

 measurements

6.  Magnetic base.

Battery Installation (Battery 1 x AAA):

1.   Make sure the digital angle gauge is switched    

 OFF

2.  Remove the battery compartment cover.

3.   Install the new battery, following the polarity    

 indicator.

4.  Replace the battery cover.

NOTE: 

Always remove the battery before storing the 

digital angle gauge.

Operation

The operation of the digital angle gauge is very simple.  Press the ON/OFF button to switch on 

the gauge and press the “ZERO” button at anytime to zero the gauge. (Fig.4.14)

To set true Zero find a level surface and place the angle gauge on the surface, switch on the dig-

ital angle gauge and press zero.  It will remember zero until the “ZERO” button is pressed again.

4.7 CHANGING THE SPEEDS

Selecting the correct spindle speed is important for safe and satisfactory results, as well as max-

imizing tool life.

To set the spindle speed for your operation, you will need to: 

1.  Determine the best spindle speed for the cutting task,  

2.  Configure the spindle speed levers to produce the required spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operation, but the two 

most important are the recommended cutting speed for the workpiece material and the diam-

eter of the cutting tool, as noted in the formula. (Fig.4.15)
