Zünd has brought to market a PCD polishing bit for finishing acrylics. Because of its geometry, the P201 bit is very efficient and distinguishes itself with unbeatable price and performance. The new P201 polishing bit is available immediately.
Routing through acrylic results in dull edges which, depending on the application, require polishing in post-processing to make them smooth and clear. With diamond polishing bit P106 and P106-A, Zünd has already been offering high-quality bits for this purpose. Now the leading manufacturer of digital cutting systems has added another pair of diamond bits to its lineup. The P201 and P201-A have a polycrystalline diamond cutting edge (PCD). Polycrystalline diamond is a high-tech manufactured diamond material that has become indispensable in many industrial finishing applications.
The PCD bit is suitable for polishing any kind of routed edges and grooves. It features a particularly long, 16 mm cutting edge, which allows for efficiently and economically polishing even thick materials in one pass. This eliminates any bothersome ridges that may occur when multiple passes are necessary for polishing the entire edge. Compared to the monocrystalline (MCD) diamond bit, the Zünd PCD has a cutting edge treated with laser, which makes it extremely sharp. This helps minimize differences in polishing results, which are further offset with the PCD’s lower cost and longer cutting edge. The PCD cutting edges offer similar hardness and wear resistance to those of MCD bits and close to the same polishing quality. With a diameter of 5.5 mm, PCD bits can safely be used for polishing grooves upwards of 6 mm wide.
The new PCD polishing bit is optimized for use with Zünd router spindles. As P201-A, this bit is also available with stop ring, which makes it suitable for fully automated routing applications with the Zünd ARC automatic bit changer. To facilitate identification and tracking, the bit type and batch number are laser engraved in the shaft.
