Tapping machine tips to know
Tapping machines are used in a wide variety of industries to automate production processes and improve quality, precision and efficiency. But, as with all machinery, the equipment technology needs to be learned and optimised to maximise its results within any application.
Tapping threads can be challenging, and even with the right equipment it still requires a number of factors to be optimised for success. Here are some user tips.
1. Use the right tap
It’s important to pick the correct tap for the type of hole you are threading and the material you are working with. Some tapping machines, such as those offered by https://www.cotswold-machinery-sales.co.uk/roscamat-tapping-machines/, may have automated features to make this easier.
2. Clamp down hard
Make sure the component material is strongly clamped, as lateral movement can damage the threads or cause breakage.
3. Use the right drill
It’s important to use the right drill for the size and material.
4. Check that work hardening is minimised
Check the condition of the drill as it’s working to make sure the component material isn’t overly hardening during the process.
5. Use the right speed
The right speed will affect the quality of the tap, so check the guidance carefully. Too fast and the thread may be damaged, but too slow and it may not drill at all.
6. Use the right fluids
There are various coolants and fluids that are available to use with tapping machines to give the best results. Use the right one for the job and clean the parts well between use to avoid any cross-contamination.
7. Check the feed value
Make sure you are using the right feed value for your programme when you are using NC applications. Floating tapping attachments tend to require 95% to 97% of the pitch for example, so the tap can make its own pitch. Use a good torque-limiting attachment to secure the tap and allow free axial movement so the tap squares correctly to the hole and prevents breakage.
These tips should help you to get better results from threading on your tapping machine.
