Walter USA's TC117, TC217 Advance Cut Taps Provide High Threading Productivity
Walter’s TC117/TC217 Advance cut taps provide high threading productivity in a wide range of materials.
The TC117 (blind-hole) and TC217 (through-hole) taps tackle
The WY80RG option provides chip control, wear resistance and higher cutting speeds.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
