borrsystem

Borrsystem is a term used in Swedish technical contexts to describe the organized approach to drilling and boring operations in manufacturing and construction. It denotes the combination of tools, fixtures, and procedures that enable holes to be placed with consistent position, size, and depth, and to be finished to a defined tolerance when required. A borrsystem typically integrates locating devices, such as jigs and fixtures, with the cutting tools (drill bits, countersinks, reamers or boring heads) and the means of clamping and guiding the workpiece. For automated environments, it may also include CNC programs, robotic handling, and sensor-based feedback that ensures repeatability.

Components and setup often include: a fixture that locates the workpiece relative to a datum; a drill or drilling head; a boring head or reamer for finishing holes; guides, bushings or drill bushings; depth stops; and measurement instruments for inspecting hole diameter and position. In manual setups, a drill press or hand drill paired with a jig suffices; in high-volume production, dedicated drilling stations or CNC mills implement borrsystem concepts.

Applications and benefits: borrsystem is used in metalworking, woodworking, cabinetry, electronics housings, and automotive components to achieve high repeatability, precise hole locations, and efficient production. It supports interchangeable parts and consistent quality, while reducing setup time for repeated operations. Limitations include upfront design and tooling costs, tool wear, and the need for precise maintenance of fixtures and alignment.
