Cutting tools should be cut from what angle?

Work part of the tool is to produce and processing chip part comprises a blade, the chip - breaking structure broken or furled, chip or channel capacity storage chip space, cutting fluid and structural elements. Some tool work is part of the cutting part, such as turning tool, cutter, boring and milling; some tool part contains the cutting portion and a part of the calibration, such as drill, reamer, reamer, inner surface broach and taps. The function of the cutting part is to cut the chip with the cutting edge, and the function of the calibration part is to repair the cutting surface and guide the cutting tool.

The working part of the cutting tool has three kinds of structure, the integral type, the welding type and the mechanical clamping type. The overall structure is on the knife body make cutting edge; welded structure is the blade brazed to a steel knife body; a mechanical clamp solid structure and two, a is the blade holder is fixed on the cutter body, another is the brazing of the cutter head is clamped on the cutter body. Hard alloy tools are generally made of welded structure or mechanical clamping structure; ceramic cutting tools are used in mechanical clamping structure.

In the choice of tool angle, need to consider the influence of various factors, such as the workpiece material, cutting tool material, processing properties (rough, finishing), etc., must be based on the specific circumstances of a reasonable choice.

Usually tool angle, refers to the manufacturing and measuring annotation angle in practical work, due to changes in the installation position of the tool and cutting movement direction, angle of practical work and annotation angle different, but differs very school manufacturing tool materials must have high temperature hardness and wear resistance, the necessary bending strength, impact toughness and chemical inertness, good manufacturability (cutting, forging and heat treatment, etc.) and not easy to deform.
