How to choose the cutting tool for vertical deep hole drilling machines?

Choosing the appropriate cutting tool is crucial for the work efficiency and machining quality of vertical deep hole drilling machines. When selecting cutting tools, the following aspects need to be considered:

The hardness of materials: Different materials have different hardness, and it is necessary to choose suitable tool materials and coatings to ensure cutting effectiveness. Usually, for materials with higher hardness, such as steel, stainless steel, etc., it is necessary to choose hard alloy cutting tools or coated cutting tools; For materials with lower hardness, such as aluminum alloy, copper, etc., high-speed steel cutting tools can be chosen.

Cutting conditions: Different types of cutting tools need to be selected for different cutting conditions, such as cutting speed, feed rate, cutting depth, etc. Generally speaking, for high-speed cutting, coated tools with high hardness and wear resistance can be selected; For heavy cutting, a tool with a larger cutting edge angle and strength can be selected.

Cutting form: Select the appropriate tool form based on the shape of the workpiece and processing requirements. Flat bottomed drill bits are suitable for processing with high surface smoothness requirements; Conical drill bits are suitable for machining holes with internal taper, etc.

Cutting stability: When selecting cutting tools, it is necessary to consider the stability of the cutting process and try to avoid vibration and tool damage as much as possible. You can choose cutting tools with high strength and stiffness, and ensure appropriate cutting parameters.

Brand and quality of cutting tools: Choosing a well-known brand of cutting tools can ensure stable quality and performance of the tools. At the same time, regular inspection and maintenance of cutting tools, timely replacement of severely worn tools, can extend the service life of cutting tools and ensure machining quality.

In summary, selecting the cutting tool for a vertical deep hole drilling rig requires consideration of factors such as material hardness, cutting conditions, cutting form, cutting stability, and tool brand and quality to ensure cutting efficiency and machining quality. In practical selection, comprehensive consideration can be given to specific processing requirements and conditions, and adjustments and optimizations can be made based on experience and actual situations.
