Disclosure and implementation of:

The first important feature is the presence of the movable centering plates on the clamping board and on the body of the device to coordinate the replaceable guide guns at any distance but limited by the dimensional scales and their replacement on hinge plates. a similar type, but with different tasks for expanding the number of models.

Another essential feature is the presence of dimensional scales on all sides of the device, which help to identify certain dimensions of the workpiece and serve as the coordinate tool the device and its components on the workpiece (from edge, previously allocated marking, etc., etc. ...).

A third essential feature is the presence of vertical slots, whose axial spacing is equal to international standard furniture construction 'System 32' with dimensional scales on the back side of the body, which allows making markings using stitching tools or write for large diameter holes.

The drilling template can be produced in different sizes and with a different number of guiding cannons arranged in a row and keep all the essential technical characteristics.

The operation of this drilling template is as follows:

If two pieces are machined simultaneously, the best quality is achieved by using a vise or specialized clamping devices to facilitate the operation to be available for all intended surfaces. The device is installed on the workpieces (12.0), in which they are located between the rear side of the body (1.0) and the clamping panel (2.0) as shown in FIG. 15. The central screw (6.0) pulls the clamping panel (2.0) to lock the device to the parts. If necessary, using dimensional scales (1.8), (2.5) deposited by the lower parts of the body (1.0) and the clamping panel (2.0), can be coordinated by the preset point. Using the dimensional scale (1.6) that are on the lateral sides of the body (1.0) one can understand the actual thickness of the workpieces, and at the same time coordinate the guiding cannons (8.0), (9.0) that are inserted in the apertures (3.1) of the upper centering plate (3.0) at the required distance due to the lateral marks (3.3). Simultaneously, on the clamping panel (2.0), by the dimensional scale (2.6), the lateral centering plate (4.0) is coordinated by means of the lateral marks (4.3) at the required distance and into the orifices (4.1) which are insert the guiding cannons (8.0), (9.0) with the required inner diameter. All two centering plates are fixed by fastening elements (10.0). At the same time, the rear side of the body (1.0) through vertical slots (1.3) being guided by the dimensional scale (1.7), using the stitching or writing tools, are made marks for holes on the third surface. As long as the holes are drilled through guiding cannons (8.0), (9.0), to the desired depth, the device is removed from the parts and finished producing the piercing by the marks made on the third surface.

In addition, the machined parts can be applied at right angles by means of special mounting supplies of the appropriate type.
