Bohrvorschub

Bohrvorschub is a machining term originating from German, referring to the linear feed or advancement of the tool or workpiece during drilling or similar machining processes. The term is particularly associated with metalworking and manufacturing, describing the controlled movement that determines the rate at which the cutting tool progresses into the material.

In the context of drilling, Bohrvorschub influences the efficiency, precision, and surface quality of the hole being produced. A proper feed rate balances material removal with tool longevity, preventing issues such as excessive tool wear, overheating, or material deformation. Typically, the Bohrvorschub is specified as the distance the drill advances per revolution or per unit time, depending on the machine setup and material properties.

The appropriate setting of Bohrvorschub depends on various factors, including the material's hardness, the diameter of the drill, and the desired finish. For example, softer materials permit higher feed rates, while harder materials require slower advancement to avoid damaging the tool. Modern CNC machines often automate this process, using pre-programmed feed rates optimized through empirical data or simulations.

In practical applications, controlling the Bohrvorschub is crucial for maintaining high production quality and efficiency. It is a key parameter alongside spindle speed (Drehzahl) and cutting speed (Schnittgeschwindigkeit). Proper adjustment of the feed rate helps optimize machining time, reduce tool costs, and ensure dimensional accuracy.

Overall, Bohrvorschub is a fundamental concept in machining technology, emphasizing the importance of precise feed control to achieve high-quality results in drilling and related operations.
