3 Key Factors to Consider when Conducting Drilling and Tapping Processes
29 September 2021Parts and components, especially those that are made from metals, undergo a lot of processes before they are distributed to specific industries. Two processes that are often applied to metal parts and components are drilling and tapping.
Drilling is the process of creating holes in a part or component, while tapping is the generation of threads into the sides of the holes. These processes may be different in terms of their working principles, but they can work together to ensure that certain parts and components can be fully maximised by businesses in various industries.
When conducting drilling and tapping processes, there are several key factors that one must consider. Some of these factors are as follows:
- Initial Arrangement
One of the factors that need to be considered when conducting these processes is the setup of their respective tools. A great set up for the tools may yield the best results possible and prolong their service lives. Tools that have excess runout may boast shorter service life and could cause irregularities on the holes. The runout of the tools may even get worse if they boast poor rigidity. High-quality tools, alternatively, will only have minimal runout and can yield great results. To ensure that the tools can generate great results, they must be cleaned regularly. Great results are also expected if the tools are placed appropriately. Workpieces must likewise be held firmly on a flat and levelled surface.
- Feeds and Speeds
Feeds and speeds are pivotal in ensuring that the drilling and tapping processes are done effectively. Feeds or feed rate determine the relative linear speed between the workpiece and the tool. Speeds or speed rate, alternatively, refer to the rotation speed of the tool or the workpiece. Obtaining the correct value of feeds and speeds must be done to ensure that the machining processes yield high-quality results. The feeds or feed rate of tools may be too low if inconsistent chips are present during the machining processes. Too high feed rate, on the other hand, may lead to stalled tools.
- Proper Lubrication
For the drilling and tapping tools to be effective, they must be lubricated properly. The application of a suitable lubricant can effectively reduce the friction of the cut and minimise heat. In some cases, applying wax or stick lubricants can be cost-effective as they do not generate a lot of mess. But if a business will be utilising high-quality coated carbide bits, they do not generally need lubrication since they can already resist high temperatures. Coolant, alternatively, can be applied to the tools so that the chips from the workpieces can be removed easily.
