PRECAUTIONS

Before commencing the installation it is important to read this section rst.

Travel Length

1. The travel length of the glass graduated scale must be longer than the maximum travel

of the machine, there should be at least 10mm clearance between the ends of the glass

scale and the maximum travel of the machine as shown in Fig. 1

(Clearance > 10mm)

Mounting Selection

2. To ensure the graduated glass scale to be installed is reliable, and to avoid any possibility

of the scale misalignment, the scale should be installed on a machined at surface of the

machine wherever possible. In the case where there are no machined at surfaces

available, optional backing plates are available and should be used. Wherever

possible the scale ends and the reader head should be installed on a at surface.

Alignment

When using a lever dial indicator to align the scale, it is important to ensure that the angle

between the Indicator lever tip and the surface being measured must be less than 30° to

avoid a cosine measurement error. If a vertical dial indicator is used as per the following

gures shown, it is important to ensure that the dial indicator is perpendicular to the mea-

sured surface to also avoid the cosine measurement error. (Fig. 2)

Mounting Position

4. The opening of the scale must not be

installed as to be directly exposed to swarf,

oil, water, dust or other foreign products.

(Fig. 3)

Covers provided should be installed.

Fig . 3

Backing Plates

5. In cases where machined at surfaces are

not available, optional backing plates

should be used to provide a at datum for

the installation. (Fig. 4)

Fig. 4

Mounting Plate

Cover Clearance

6. A clearance of at least 3.0mm between the

scale and scale cover should be maintained.

(Fig. 5)

Drilling and Tapping Holes

7. When drilling and tapping the holes be sure

that the drill and tap are square to the cover.

(Fig. 6)

All tapped screw holes must have at least 6

threads to allow the screw to be rmly

secured into the holes. When the screw is

needed to secure a heavy load, the tapped

holes must have at least 8 threads. After

tapping, the holes must be deburred and

cleaned

Fig. 5.

Fig. 6

Securing Cable

8. All cables must be xed, but allow for the

maximum machine travel movements.

Diagram (Fig. 7) recommends the

minimum radius that should be used for

bending the scale cable. Use the cable

clamps supplied to secure the cables to

the display arm. Fig. 7

Grounding & Earthing

9. Grounding / Earthing is very important for the

noise immunity. The grounding wire must be

attached between the metal body of the machine

and the grounding pin on the back of the display

unit to be eective. (Fig. 8)

Final Alignment

10. The Horizontal and Vertical alignment

measurement are taken at 20mm away

from the scale ends as shown in the

diagram. (Fig. 9)

1. Requirements for the Mounting Surface

a) If the scale mounting surfaces are not parallel to each other (ie. As per shown in figure A

and B), the parallelism of the two mounting surfaces must be less than 0.1mm.

b) If the mounting surfaces are perpendicular to each other (i.e. As per shown in figure C),

the squareness of these two mounting surfaces must be less than 0.1mm. (Fig. 10)

Fig. 10

2. Scale Alignment

It is very important that the scale must be

aligned parallel to the travel of the machine

slide. For scale travel less than 950mm, the

maximum parallel error between the scale and

the machine slide must be less than 0.1mm –

0.15mm. For scale travel longer than 950mm,

the maximum alignment parallelism error must

be less that 0.15mm - 0.2mm. (Fig. 11)

Direction

3. Clearances Between the reader head and scale body:

The clearance between the reader head and scale body must be

kept between 0.8mm-1.5mm. The reader head must be less than

0.5mm parallel with the scale and can be set with feeler gauge to

allow the reader head to move unrestricted along the scale. (Fig.

12)

Scale Direction

Before mounting the scales it is important that the scale reads in

the correct direction.

The chart below indicates the reading that should be obtained

when traveling in that direction. (Mill Fig.13, Lathe Fig.14)

Note! To reverse the scale direction refer page 6 of manual

I. Enter “SETUP” and then press until “DIRECT”

appears in message window.

Press !ENTER) to enter direction setup;

X window, Y window and Z window will display “O” or “I”

against them.

2. Select an axis by pressing the “X”, “Y” or“Z” button and then

press enter. This will display “O” or “I” against the “X”

axis.

3. Using the to change the display from “O” to “I” to

change the direction of the scale. Once the change has

been made press “enter” to conrm and save the change

and exit the setup section.

CHANGING THE SCALE DIRECTION.

After the scales have been installed it may be necessary

to change the direction of the scale so that it reads cor-

rectly. E.G. If you are using the scale on a lathe, then the

scale that reads the diameter must get smaller as the

tool gets closer to the centre.

This is all controlled by the display unit in the“SETUP”

section.

éê

If the linear scale is installed as the gure below (facing operators):

Direction “0” means the display value will increase when scale moves from right to left and

decrease when scale moves from left to right.

One of the easiest ways to set up an “X” scale on a

milling machine, if the side of the table is machined,

is to clamp two parallels to the flat table surface that

the table travels on and sit the scale on the parallels.

Carefully drill and tap the holes to take the screws

provided. (Fig. 15)

FITTING THE “X” SCALE ON A MILLING MACHINE

Fig. 16

When the scale is mounted then fix the reader

head to the saddle, if necessary packing the head

to ensure that it is parallel and in line with the

scales. (Remove the Grey packing between the

reader head and scale which allows for the correct

clearance and holds the reader head parallel to

the scale.) (Fig. 16)

Mount the cover over the scale, and drill and tap

the holes to secure it to the table making sure that

there is 3mm clearance between the cover and the

scale. (Fig.17)

Fig. 17

Fig. 18

FITTING THE “Y” AXIS SCALE.

If the surface is not machined, mount the backing

plate and use the grub screws to adjust the backing

plate, checking with a dial indicator until the scale

is square and perpendicular to the machine slides.

(Fig. 18)

Fig. 19

Mount the scale on the backing plate using the

pre-drilled holes, checking that the scale is parallel

with the machine slide with a dial indicator. (Fig. 19)

After the scale is aligned to the axis, then drill and

tap the saddle to suit the bracket provided and

mount the bracket ensuring that the reader head

is sitting correctly so that when the reader head is

attached it will be square and parallel to the scale.

(Fig. 20)

Fig. 20

Fig. 21

Mount the bracket on the saddle to take the

reader head making sure that the reader head is

in line and parallel to the scale. Secure the cable

making sure to leave enough free cable to allow

for the travel of the slide. (Fig. 21)

FITTING THE “Z” AXIS SCALE

Before mounting the scale ensure that it will read“+”as you wind the table down, increasing

the distance from the table to the cutter

The “Z” axis scale should be installed on the side of the column ensuring that the open side of

the scale is away from direct swarf and coolant and that the travel is in the right direction “-“

towards the spindle and “+” away from the spindle. The bracket (Fig. 22) is mounted off the

knee, and around the scale (Fig 23) to allow for the cover (Fig.24) to protect the scale, where

excessive coolant & swarf are present.

LATHE INSTALLATION

To install a readout on a lathe the following tips can be used. To mount the cross slide scale

select a flat surface that is suitable and clear of the traveling parts of the lathe.

The scale should be mounted ensuring

that it is parallel and square to the slide.

(Fig. 25)

Fig. 25 Fig. 26

When mounting the reader head if necessary pack the reader head (Fig. 27) so that it travels

in line and square to the scale to avoid any damage to the scale. Testing for parallel can be

done by either a dial indicator or a precision level. (Fig. 26) The cover must be tted (Fig. 28)

Fig. 29

The longitudinal scale should be mounted on the back of the Lathe (Fig. 29) with the open

side of the scale facing down and must be parallel to the bed. The reader head is mounted

to the saddle (Fig. 30) via the brackets provided. Some modication may be required for

some lathes. Covers should be mounted over the slides. (Fig 30)

The DRO is mounted to the bracket using the two angle brackets and the mounting pin and

secured with the bolt supplied. (Fig. 37)

FINDING A SUITABLE MOUNTING POINT.

Before mounting the DRO nd a suitable at surface to

anchor the bracket. Check that the movement of the DRO on

the bracket will clear all items and is in a place where it can

be read and operated easily.

Make sure that the cables attached to the DRO will reach

with out being stretched and caught or tangled.

NOTE:

Modication to brackets or reproducing of additional

brackets or spacers maybe required to suit your particular machine
