threading
The document outlines detailed specifications for threading inserts, including sizes, profiles, and grades. It covers both partial and full profile threading standards such as ISO Metric, UN, and Whitworth. Insert sizes range from 06 to 27, with corresponding dimensions provided.
An example procedure for selecting thread turning is detailed, including steps like choosing the thread turning method, insert size, toolholder, helix angle, anvil, carbide grade, and cutting speed. The example uses an ISO Metric M40x2.5 external right-hand thread on material 4140.
Technical data includes cutting conditions based on workpiece material type, dimensions, chip flow character, hardness, and thread application. Considerations for machine stability, RPM, clamping system, and coolant type are also included.
Recommendations are provided for selecting the correct anvil, carbide grade, and cutting speed. The document suggests a feed direction towards the chuck and specifies the number of passes required for the threading process.
Extensive tables list order codes, reference numbers, pitch dimensions, and stock grade codes for various threading inserts, providing critical data for selecting appropriate threading tools.
The document details specifications for TRAPEZ, AMERICAN ACME, STUB ACME, and UNJ threads, including geometry codes, pitch dimensions, and stock-grade codes for both external and internal threads.
Stock availability for each thread type is provided, indicating items available on request and referencing additional details on page E-694.
Tables include critical dimensions such as IC (Internal Clearance), L (Length), X, and Y, along with stock-grade codes like PH6920 and PH8920.
Order codes are generated by combining geometry codes with stock-grade codes. Additional technical data and spare parts information are referenced on various pages.
Three primary methods for thread cutting are outlined: radial infeed, flank infeed, and alternate flank infeed, each recommended based on specific conditions.
A detailed table is provided for rotation, feed direction, and helix method for different thread insert and toolholder configurations.
The helix angle is crucial for ensuring the cutting edge does not rub against the workpiece. A formula and diagram are provided for calculation.
Tables recommend the number of passes for various thread types, organized by pitch (in MM or TPI) for optimal thread cutting.
Specific data for thread types like MJ and RD threads, with recommended numbers of passes based on pitch measurements, is included.
