Conductor for drilling holes -A device used in engineering to simplify the processing of a part. In fact, it is a template that serves to guide the cutting tool, or position the workpiece. Can be used on a variety of equipment, such as a drilling machine or a diamond drilling rig.
In machine-building production, conductorsare quite precise devices (up to 0, 05 mm (depending on the requirements for the manufactured part)). They are of two main types: overhead (in the form of plates) and box, which are voluminous structures. There are also conductors for drilling of mixed type. These adaptations are used to reduce labor intensity: from the technological process of processing the part, the marking operation is removed, in addition, it becomes possible to drill several holes at the same time.
The conductor for drilling is used only inserial and mass production. This is due to the fact that for a small batch of parts it is not practical to produce a separate device, which, in addition, will have to be separately installed and adjusted.
A conductor for drilling is usually appliedTo process several holes lying in one plane. Best of all, if the parts are unified by size, this will allow using a device for a wide range of products.
The conductor for drilling is also used inlight industry and construction. Such devices are only of an overhead type, made of sheet steel or lighter materials, for example wood or plexiglass. These products are not designed for greater accuracy, the positioning error is only ± 0.5 mm. But this is more than enough to make holes for furniture fittings or to drill a series of holes in the wall of the house. As equipment use a conventional drill or a drilling machine of desktop type.
You can independently manufacture a conductor forhousehold needs. It will be needed in the repair, when it is necessary to make many similar holes and there is no desire to waste time on preliminary marking. For its manufacture, you can use any improvised materials: on a sheet of metal or a wooden board to plan and drill all the necessary holes that will serve as guides. If necessary, an additional plumb line is made so that the shavings or concrete crumb does not fall to the floor. You can make a conductor without dust, when the template is covered with a specially fitted half of a plastic bottle.
The main advantages of these devices arehigh accuracy of the positioning of the holes without preliminary marking, high labor productivity and a decrease in the deviation of the perpendicularity (due to the guide bushings). However, the use of a conductor for drilling is not always economically justified, especially with small batches of parts in production.
