A device for the manufacture of drilled holes, cut-outs, plane surfaces or the like, includes an attachment structure, which is designed for the attachment of the device to at least one component to be machined, a feed device, which is designed to track a drill of a drilling machine, and a control device for controlling the feed device and a drilling machine. In one example, the feed device includes a support for the drilling machine, which is arranged substantially in the center of a crossbeam.

Device for the manufacture of drilled holes, cut-outs, plane surfaces, or similar

A lubricating mixture of a lubricant and air is supplied to a cutting location by a lubricating tool with a spring biased piston dividing a cylinder into an air chamber and a lubricant chamber. The air chamber is connectable to a pressurized air source. The lubricant supply chamber is selectively connectable through a control valve to a lubricant source or to an exchangeable lubricant and air mixing attachment also connected to the pressurized air source. The attachment includes three flow restrictors. Two restrictors feed air and lubricant to a mixing area. One restrictor feeds the mixture to an output. Different sets of restrictors with different flow restricting characteristics provide an exact mixture dosage for satisfying any cutter lubricating requirement. It is merely necessary to replace one attachment by another attachment having different flow restricting characteristics.
