A General Turning THREADING Parting and Grooving B How to choose your threading tool Select the threading method, page C4: Select insert size, grade, geometry and type of infeed Select tooling system and type of holder Select suitable shim Threading Tooling systems Choose your pitch and size of insert If possible choose a multipoint insert for better productivity Choose your geometry, grade and type of infeed Detailed recommendations on page C80 Choose Coromant Capto or shank tool, depending on clamping possibilities in turret/spindle, on page G5 Choose type of holder and coupling size or shank on page C7 The insert seat must correspond to the size of the insert Choose correct shim for your pitch/workpiece diameter See page C45 for CoroThread 266 and page C57 for T-Max U-Lock Shims are used to give different tilts to the insert and are available in 1° steps from -2° to +4° Threading holders are supplied as standard with a shim giving a +1° inclination angle Note: No shims for smaller diameter bars as the angle is fixed at +2° Select size, number of passes and speed The recommendations are intended as starting values (Page C70) Cutting speed recommendations, see page C82

General information J A General Turning THREADING Choosing inserts and tools Selecting the method of thread cutting The machine tool and the design of the workpiece determine which method is to be used to cut a thread Working towards the chuck is the most common method The advantage of using right hand tools for right hand threads and left hand tools for left hand threads is that the holder design is made to give maximum suport to the insert Working away from the chuck is also possible but when producing right hand threads with left hand tools and vice versa, compensation must be made for the negative helix angle by means of changing the shim Note that a holder and insert of the same hand must be used together for the CoroThread and U-Lock programs Parting and Grooving B C Methods

infeed can have a decisive impact on the threading operation The infeed recommendations are intended as starting values Suitable number of passes must be determined by trial and error The harder the workpiece, the more passes will be required - The workpiece diameter should not be more than 006 inch (0.14 mm) larger than the max diameter of the thread to achieve optimum tool life - Infeeds of less than 002 inch (0.05 mm) should be avoided; for austenitic stainless steels, avoid infeeds less than 003 inch (0.08 mm) - When using grade CB20 the max infeed value should be 003 inch (0.07 mm) - For C-geometry inserts, spring pass (a pass without infeed) should not be used - For Multi-point inserts it is essential that the recommendations on page C79 are used - The recommended number of passes for full form inserts can also be used for V-profile inserts C A-geometry C geometry Threading F-geometry Tooling systems G Multi-task machining H I Radial infeed Modified flank infeed
