GE 20 engraving device

The GE 20 engraving device is the ideal instrument for engraving ornamentations, letters or numbers on metal or plastic. Signs can therefore be created, small valuables decorated and individual embellishments created on jewellery with ease.

Retailers keep a broad selection of stencils in stock for this purpose, including every conceivable kind of template for plant ornamentation, animals, coats of arms, etc. Stencil templates can, of course, be individually created where a freely invented figure is to be engraved. In this case, no limitations are placed on creativity, and inspiration can be found practically anywhere!

Drawing stencils are provided for creating letters and numbers. These are fixed in position using a guide rail included in the scope of delivery. A maximum of 14 characters can be fitted here adjacent to each other, more than enough for nameplates or similar. The stencils are traced precisely with the guide marker on the GE 20 engraving device which, in turn, is guided with a comfortable ball handle.

This movement is reduced and transmitted to the clamped milling tool. The reduction ratio can be fixed at 2:1, 3:1, 4:1 or 5:1 by simply adjusting two screws.

Our step clamp set (article number 24256) is ideal for clamping and aligning the workpiece to be engraved. This is described in detail in chapter "Accessories" later in this manual.

Further information on useful accessories is also contained in this section. We hope you enjoy working with the engraving device!

Scope of delivery:

• GE 20 engraving device
• Allen key 1.5 mm
• Allen key 3 mm
• Allen key 5 mm
• Screwdriver HX 2.5
• Letter strip
• Letter set
• Fastening set for letter strip

Assembly of the GE 20 engraving device

Fitting the guide marker:

For packaging reasons, the guide marker is not prefitted, but assembly is very simple, as illustrated in Fig. 1:

1. Unscrew the ball handle 1 and stop 2 from the guide marker 3
2. Screw the guide marker 3 into the threaded hole 4 provided for this purpose
3. Screw the ball handle 1 and stop 2 into place again

Fitting the guide arm:

1. Insert axle 1 through the opening in the guide arm 2 (see Fig. 2)
2. Insert axle 1 together with the guide arm into the hole on the T-slot table 3 intended for this purpose (see illustration). Prior to this, fit the spacer sleeve 4 to the axle 1. Ensure that the axle is turned so that the screw 5 makes contact with the flat position on the underside of the axle!

Selection of reduction ratio

Four reduction ratios can be configured by varying the lever ratios on the guide arm: 2:1 (A), 3:1 (B), 4:1 (C) and 5:1 (D). Only varying combinations of positions of both elements of the guide arm need to be configured for this purpose.

This is really easy. Simply unscrew the knurled screw 1 (Fig. 3), select the desired position for the arms and screw the knurled screw in again.

Note that the arms are labelled with numbers, as shown in the illustration!

We have labelled the respective hole combinations with letters in the illustration which correspond to the details specified above in the text.

For example, Fig. 3 illustrates the configuration for a reduction from 2:1 (i.e. the en-graving is half the size of the original here).

On the other hand, Fig. 4 illustrates an example of a reduction of 5:1.

Positioning the number and letter plates on the guide rails

Push the desired number and letter plates laterally into the guide strip, as illustrated in Fig. 6.

Caution:

Ensure during this that at least 11 number and letter plates are used!

Where surplus plates are required for this purpose, please ensure these are reversed (face down) when pushed into the guide strip!

Please note:

A pressure piece should be inserted at the beginning and end, as shown in the illustration.

Securing the guide rail to the T-slot table

See Fig. 7 a and b: Push the guide strip with the desired letter and number combination and the screws and square nuts included into the centre of the larger of the two tables and screw firmly into position.

The electric tool can then be clamped into the 20 mm fit. Simply insert as illustrated in Fig. 8 and clamp firmly with the Allen screw 1.

Please do not forget to clamp the tool to be used in the electric tool prior to this!

Attention: The used power tool has to be operated with collets! Using the tree-jaw chuck is not possible.

Align the positions of individual elements and the engraving device settings:

Aligning the guide rail and workpiece (Fig. 9)

Naturally enough, options for movement of the guide arm are limited, depending on the reduction configured. This task is therefore important when it comes to aligning the workpiece position with the working range of the engraving needle.

1. Fix the workpiece 1 temporarily to the worktable 2 using appropriate fastening material (e.g. collet set, article no. 24256)
2. Then traverse to both end positions of the number and letter sequence 4 to be engraved with the guide marker 3, observing the movements of the engraving needle. Do these

remain in the correct area of the workpiece in every position, and can the needle move freely?

1. Please also ensure that the needle does not collide with the fastening media! Following correct aligning, please clamp the workpiece firmly.

Adjustment of the T-slot tables in their guides

This is a further option to align the positions of the workpiece and the stencil with each other if necessary. The procedure is as follows:

1. Release the clamping screws 1 (Fig. 10)
2. Push one or, if necessary, both tables 2 into the required position
3. Retighten the clamping screw 1

Aligning the height setting of the engraving needle and guide marker:

Two options exist for varying the height of the guide arm relative to the workpiece thickness and the engraving needle. Please proceed as follows:

Adjusting the height of the swivel joint:

1. Release the locknut 1 (Fig. 11)
2. The height can now be adjusted by turning on the handle 2
3. Tighten the locknut 1 again when adjustment is completed

Adjusting the height of the guide marker:

1. Release the locknut 3.
2. The height position can now be adjusted by turning the pin 5 on the handle 4.
3. Tighten the locknut 3 again when adjustment is completed.

The guide arm can be raised to a certain degree (see Fig. 11). This is essential when working if the guide marker needs to be moved, but the engraving needle is not engaged.

In addition, improved access to the electric tool when raising facilitates changing the engraving needle.

Engraving

Ensure that all settings are correct. This applies in particular to the guide arm height setting!

1. Activate the electric tool
2. Insert the guide marker into the slot where the desired number and letter plate is located.
3. Engrave the numbers and/or letters.
4. Raise the guide arm following completion of a character so that the engraving needle can move freely from engaging into the next letter without colliding with the workpiece.
5. Repeat the operation for each number and letter (see Fig. 12). For example, the arm should be raised here following movement 1, movement 2, etc.
