What is BS 1660-1 - Self-holding tapers about?
BS 1660-1 is the first part of the BS 1660 multi-series that discusses machine tapers.
BS 1660-1 specifies the dimensions of self-holding tapers for tool shanks with a small taper of about 4 % to 5 %, classified, according to their use, into the three following categories:
- Tapers for general use
- Smaller tapers
- Larger tapers
Who is BS 1660-1 - Self-holding tapers for?
BS 1660-1 on machine tapers is useful for:
- Manufacturers of hardware tools
- Designers of hardware tools
- Quality control personnel
Why should you use BS 1660-1 - Self-holding tapers?
Self-holding taper is a tapered spindle used on lathes and drill presses to mount tooling. These tapers have types that vary in dimensions and designations. Any discrepancies in these dimensions can cause difficulties in fitting the tapers into tools.
BS 1660-1 specifies the dimensions of grooves and holes necessary for the design of tapers for applications where coolant supply is required. This ensures that your tapers fit the spindles accurately and their design is free from any deviations and deformations which can compromise the integrity of the machines.
Overall, the guidelines of BS 1660-1 enable you to identify the appropriate self-holding tapers for that have a suitable fit for your machines.
