Synchronous threading To reduce process times in threading operations, manufacturers are increasingly favoring higher rotation speeds and cutting speeds (HSC). For high cutting speeds especially, synchronous tapping is recommended. The Synchrospeed product range from Walter Prototyp has been optimized specifically for this particular process. The key characteristics of these tools are their extremely high clearance, their extra short threaded part and their sharp cutting edges. Weldon chucks as well as collet chucks (where possible with square drive). Both fixtures have the disadvantage of being unable to compensate for the axial forces that are generated A better alternative is the Protoflex C tapping chuck with minimum compensation. Protoflex C is a tapping chuck for machining centers with the capability to perform rigid tapping. It guarantees a precisely defined minimum compensation and is matched to the geometry of Synchrospeed tools. While Synchrospeed threading tools have been developed exclusively for synchronous applications, ECO threading tools can be used for both rigid and conventional tapping. Synchronous tapping requires a machine that can synchronize the rotary motion of the main spindle with the feed motion. This is usually a standard feature on today's machining centers. Synchronous taps are compatible with conventional Protoflex C synchronous tapping chuck For order documentation, see page G 96. The special features of Protoflex C Unlike other tapping chucks, the Protoflex C design is based on a precision-machined flexor with high spring rate, which compensates both radially and axially for microscopic deflections. The patented microcompensator is made from a special alloy originally developed for NASA. The conventional synchro chucks on the market use plastic parts for this purpose, but these lose their flexibility over time, at which point they are no longer able to provide microcompensation. Flexor with minimum compensation The Protoflex C helps to reduce considerably the pressure forces that act on the flanks of the tap. This results in improved surface quality on the flanks of the cut thread greater process reliability thanks to the reduced risk of fracture, particularly where dimensions are small. a longer tool life due to less friction. maximum utilization of machine power. threading D 450 WALTER Technical information PROTOTYP
