Wiper technology in carbide cutting tools in a lot of attempts have been made and tested. Use wiper inserts advantage is obtained at a higher feed rate - processing capacity. Principle wiper shown in Figure 3. In fact the principle is the wiper tip arc after placing a large arc or more large arc. Since the contact area is wider and can reduce the ratio of hard turning generate peaks and valleys of the surface, which makes the blade has a blade with a large arc or circle the same effect. It also makes the feed amount of the surface roughness does not deteriorate after the increase.

With the advances in tool manufacturing technology, this principle is used pcbn blade is feasible. Benefits The wiper technology for hard turning has two aspects: First, increase productivity, and the second is to reduce the contact time and provide longer tool life. In gear machining, wiper inserts are typically used for processing the hole.

One of the latest pcbn wiper technology is secomax cbn100 crossbill: emoji: wiper blade development (Figure 4). This unique blade and the integral pcbn points left and right wiper blade design combines the advantages. Until recently, wiper blade design integral pcbn on its ability to receive processing steps toward limiting. This is due to the wiper design a cutting edge and on the opposite side of the corner radius design. cbn100 crossbill: emoji: Release the blade has solved this problem, both supply the right type of blade type also supply left. It can be used toward the axial turning steps (take advantage of wiper technology), and attributed to this design, it can be processed into a perfect arc.
