    Thread milling up to 65 HRC with easier radius correction

    Milling a thread into a hard material of up to 65 HRC without any pre-drilling is an operation that is now enabled by the newly developed WH-EM-PNC thread milling cutter from OSG. At EMO Hannover 2017 the company will be introducing the tool together with its DCT thread correction aid.

    The newly developed thread milling machine WH-EM-PNC is considered to be the ideal solution especially for tool- and mold-making.

    Although thread milling tools are not entirely new, as the exhibitors from OSG admit, their test results speak for themselves. Very long service lives were reportedly achieved, making the exhibited thread milling cutters particularly interesting for the hard machining segment of the die- and mold-making industry, where thread cutting is usually the last task carried out. The cutting tool specialists point out that conventional taps are not necessarily process-safe when working with hard materials because they can often break. Nevertheless, they insist that many more threads can be cut with their new thread milling cutter. A further advantage is that if a break does occur, the tap crumbles, so to speak, making removal quick and easy. The manufacturers will also be showcasing their DCT thread correction tool at the fair, a diameter testing tool that tackles current issues that occur in practice. The device makes it possible to check the range of the diameter in terms of dimensional tolerance, enabling the measurement of the effective diameter and thread tolerances. This is said to significantly facilitate radius corrections and a true-to-gauge thread can be effectively produced in a second procedure. Regardless of this, OSG specifies the radius correction on every tool, a value that can then also be entered into the control system of the machine tool to obtain an immediate true-to-gauge thread.
