What is ISO 2250:2017 Finishing reamers for Morse and metric tapers, with cylindrical shanks and Morse taper shanks?
ISO 2250:2017 is a standard specification published by the ISO, that pertains to the design and manufacturing requirements for finishing reamers used for Morse and metric tapers, with cylindrical shanks and Morse taper shanks.
Finishing reamers are used in the final stage of a machining operation to achieve a smooth and precise surface finish, typically on a pre-drilled hole or bore. These reamers have a cutting edge that is designed to remove a small amount of material from the inside of the hole or bore. And they are commonly used in the production of metal components such as engine blocks, gears, and bearings.
ISO 2250:2017 specifies the dimensions, tolerances, and other requirements for finishing reamers with cylindrical shanks and Morse taper shanks. Which are commonly used in machine tool operations. The standard defines various parameters. Such as the overall length, shank diameter, cutting edge angle, and flute length, that ensure the compatibility and interchangeability of the reamers with other machine tools and components.
In summary, it provides a set of specifications and guidelines for the design and manufacturing of finishing reamers used for Morse and metric tapers, with cylindrical shanks and Morse taper shanks.
Requirements of ISO 2250:2017
ISO 2250 specifies the following requirements for finishing reamers for Morse and metric tapers, with cylindrical shanks and Morse taper shanks:
Dimensions and tolerances: The standard specifies the dimensions and tolerances for various parameters. Such as the overall length, shank diameter, cutting edge angle, flute length, and chamfer dimensions. These dimensions and tolerances ensure the compatibility and interchangeability of the reamers with other machine tools and components.
Materials and hardness: This standard specifies the material requirements and hardness values for finishing reamers. The reamers should be made from high-speed steel, cobalt high-speed steel, or solid carbide. Also, the hardness values should be within a specific range. To ensure the appropriate level of durability and wear resistance.
Design features: The standard specifies the design features of finishing reamers. Such as the number of flutes, the shape of the cutting edge, and the helix angle. These design features are critical to the performance and efficiency of the reamers.
Marking and identification: The standard requires finishing reamers to be marked or labeled with specific information. Such as the manufacturer’s name or trademark, the type or size of the reamer. And any relevant markings indicating compliance with ISO 2250.
ISO 2250:2017 ensures that finishing reamers for Morse and metric tapers, with cylindrical shanks and Morse taper shanks, are manufactured to precise standards and specifications. Which in turn ensures their compatibility, interchangeability. And performance in machine tool operations.
Benefits of this ISO Standard
Improved compatibility and interchangeability: By specifying the dimensions and tolerances for finishing reamers, the standard ensures that the reamers are compatible and interchangeable with other machine tools and components. Thus, this improves the efficiency and flexibility of the manufacturing process.
Increased precision and accuracy: The standard’s requirements for design features. Such as the shape of the cutting edge and the helix angle, help ensure that the finishing reamers produce a precise. And accurate surface finish on machined parts.
Enhanced durability and wear resistance: By specifying the material requirements and hardness values for finishing reamers, the standard ensures that the reamers are durable. And have the necessary wear resistance to withstand the demands of machine tool operations.
Improved quality control: The standard’s requirements for marking and identification help ensure that finishing reamers are traceable and that the manufacturer’s information is readily available. Which can help with quality control and problem-solving in case of any issues or defects.
