Overview
ISO 2587:1972 is an international standard published by the International Organization for Standardization (ISO) that specifies the precise dimensions for side and face milling cutters with plain bore and key drive in metric series. These milling cutters are designed to fit on cutter arbors and are used primarily in machining processes involving the milling of materials. This standard covers cutters with straight-sided teeth and those with double helical (staggered) teeth, ensuring consistency and interchangeability in manufacturing and industrial applications. The range of outside diameters for these cutters aligns with the recommendations set out in ISO 523.
Key Topics
- Dimensional Specifications: Defines the exact size parameters of the cutters, including outside diameter, bore, and keyway sizes, facilitating compatibility with cutter arbors.
- Tooth Types: Applies to cutters featuring both straight teeth and double alternate helix teeth, expanding versatility for different milling needs.
- Metric Series Focus: All dimensions and tolerances are standardized according to the metric system, supporting global consistency.
- Compliance with ISO/R 240: The standard references ISO/R 240 for bore and keyway dimensions to maintain interchangeability across milling cutter components.
- Applications in Tooling: Primarily intended for use in metalworking and precision machining industries that rely on milling operations.
Applications
ISO 2587:1972 is essential in various industrial and manufacturing settings, particularly those involving precision milling tasks:
- Metalworking Shops: Enables the selection of milling cutters with guaranteed dimensional accuracy, improving tool fit and machining quality.
- Cutter Arbor Manufacturing: Helps ensure that cutter arbor designs can accommodate cutters with standardized bores and key drives.
- Automotive and Aerospace Industries: Supports the machining of high-precision components by providing cutters conforming to exact specifications.
- Tool & Die Making: Offers reliable cutter options necessary for producing detailed dies and molds requiring exact cuts.
- Mechanical Engineering: Facilitates maintenance of machinery involved in milling by providing standardized cutter choices.
By adhering to ISO 2587, manufacturers and end-users achieve enhanced compatibility between cutters and arbors, reducing downtime and tool replacement costs.
