Used Machinery: Drilling machines

Drilling machines - more than just making holes

The term drilling machine includes not only machine tools but also the hand drills known from everyday life and craft with the multifunctionality for wood, steel and stone. The hand drill is a universal machine in which the material to be drilled is determined only by the choice of tool. If the hand drill is to be used for drilling in stone or concrete, the impact function of the hand drill is also required. Rotary hammers have proven to be particularly effective for concrete.

Now we come to the structure and the most important components of a drilling machine (the machine tool is meant here). First of all, the frame should be mentioned here. This carries all important components such as spindle, drives, clamping devices, slide, tools, table and the weight of the workpieces.

When it comes to automation, a lot is also possible with drilling machines. This development goes step by step from the simple column drilling machine with manual feed to the automated control of the axes and spindles (CNC control) and the automatic drilling machines. In the end, the simple drilling machine can become a drilling center or a drilling and milling center. With the help of a magnetic stand, a normal hand drill can also be turned into a locally independent column drill. However, this only works if it can be placed on a metallic and magnetically appealing surface. The classification of the categories for drilling machines.

At tramao we have decided on the following categorization of the drilling machines:

• Automatic drilling machines
• Drilling & boring machines
• Jig drilling machines
• Multi spindle drilling machines
• Radial drilling machines
• Gang drilling machines
• Revolving drilling machine
• Column type drilling machines
• Other drilling machines
• Box column drilling machines
• Deep-hole drilling machines
• Bench type drilling machines

All machining centers, including those that contain drilling machine functions, are grouped together on tramao.de in a separate "Machining Centers" category. The advantages of the drilling centers or the automatic drilling machines lie in the economical production of large quantities with constant quality, as well as a plannable production with constant set-up and manufacturing costs.

A drilling machine can also belong to several categories. For example, a deep hole drilling machine can also be CNC-controlled. That is why it is possible on tramao.de to assign more than just one category to a machine.

However, a maximum of three categories are possible per drill.

There are many classic areas of application for drilling machines. It starts in small workshops with conventional machines and ends with complex workpieces in interlinked production systems, where the highest precision is also required from the drilling machine. For example, valve manufacture or the manufacture of stands with lubrication holes are mentioned here.

There is no typical user who uses the drill. The skilled private citizen needs these machines just like the craft or the industry.

A large number of materials can of course also be processed by drilling machines. Examples are metal, wood, plastic, glass or composite materials. As a rule, the machines can be used universally and the adaptation to the material to be drilled takes place through the choice of the tool, the feed rate and the speed of the drill.

As mentioned at the beginning of this report, not everything that looks like a hole was made by a drill. Bores can be created, for example, by punching, nibbling, lasering, water jet cutting or plasma cutting. It is also possible to produce bores on lathes or milling machines.
