This lets you take advantage of the XT Pro insert benefits in deep hole applications. The coolant configuration increases coolant flow and directs additional coolant to the cutting zone. of spiral fluted taps for blind holes (VUSP) and spiral pointed taps for through holes (VUPO) and they are suitable for a range of batch sizes, small to large. After its introduction on the market, European users have quickly recognised the series as a technological benchmark for high performance tapping. New sizes and types have since been added such as the VUSP CH and VUSP E(1.5P). VUSP CH is a coated spiral fluted tap with central coolant suitable for water-soluble cutting fluid processing. The coolant hole is optimised to allow abundant internal lubrication to prevent overheating and welding reduction resulting in improvement of wear resistance and the quality of the internal thread. Let’s consider a comparative text as an example. The test has been carried out at 15m/ minute cutting speed on a vertical machining centre with synchronous feed. 42CrMo4 steel was machined using Yamawa Z-PRO VUSP CH M8 x 1.25 using 5% emulsion as cutting fluid. After tapping more than 180 holes, the Yamawa tap proved to be still reliable in ensuring outstanding thread surfaces, while on a competitor tap significant wear occurred after 92 holes. VUSP CH tap smoothly discharges chips, allowing for continuous machining and process reliability. The VUSP E(1.5P) tap has a short chamfer length – a feature that makes it ideal for machining blind holes where there is little room between the bored hole depth and the full thread length. Finally, concluding the overview on Yamawa VU Z-PRO Series taps, it is worth mentioning the broad range of VUSP and VUPO taps’ available dimensions with M and MF thread types. Furthermore, both the VUPO and the VUSP are also available in longshank versions (JIS standard) and oversized versions from M3 to M16. n Yamawa www.yamawa.eu
