Benefits of rough machining

Source: https://www.saimotools.com/8-reasons-to-rough/ Roughing is a critical stage in the machining process. Its main purpose is to quickly remove excess material from raw materials or semi-finished products to form parts that are close to their final shape. Reasons for roughing include: 1. Improve production efficiency: Roughing usually uses larger cutting depth and feed rate, which can…

How to choose the right boring tool

Boring tool is a specialised tool for roughing, semi-finishing or finishing existing holes, mainly used for cylindrical hole machining of workpieces such as boxes, brackets and machine seats. Boring tools can be used on boring machines, lathes or milling machines with one or two cutting sections and are suitable for operations such as bore machining, reaming and profiling.

When selecting a boring tool, the following aspects need to be considered:

1.Type of boring tool: Depending on the machining requirements, different types of boring tools such as multi-flute boring tools, heavy-duty boring tools, step boring tools and indexable deep hole boring tools can be selected. For example, double-edged boring tools are suitable for low to medium power machines, non-stationary processes or large diameter machining, while heavy-duty boring tools are suitable for large, heavy-duty boring operations.

2.Machining accuracy requirements: For holes with low accuracy requirements, rough boring can be used as the final process; while for holes with high accuracy requirements, rough boring is used to remove most of the allowance, improve the dimensional accuracy of the holes and reduce the surface roughness value, in preparation for the subsequent semi-finish boring and finish boring.

3.Boring dosage: Reasonable selection of boring speed and feed is critical to ensure the hole size and finish. For example, the reasonable cutting dosage for castings is Vc=12m/min, f=1-2mm/r; for steel parts, it is Vc=10m/min, f=0.5-1mm/r2.

4.Cutting fluids and coolants: In the boring process, the use of appropriate cutting fluids and coolants is critical for chip removal, cooling and lubrication, which will directly affect hole quality and tool life.

5.Technical improvement of the tool: With the development of technology, new boring tools such as digital boring tools, vibration-damping boring tools can improve machining accuracy, reduce the time of tool setting, and can be automatically adjusted, corrected wear, compensate for errors or automatic forming.
