Connection System Boring ead For Boring eads: Pages to arge assortment of boring heads and inserts Wide range of capacity ø-ø8 ESY Operation only by allen key 0 SECURE Connection mechanism is based on a simple design but assures strong face contact. Steep taper is the key. Point Point Only one piece of a special Set Screw with a unique steep taper works to pull the boring head in an axial direction resulting in strong face contact. Boring operations requiring large stock allowances are made possible by the B Pin, designed to provide high torque transmission.

It is further helpful to arrange and minimize the interference while retaining its rigidity. Including chamfering tools, adjustable for any bore depth position, the optimum tool layout for every workpiece is easily assembled. Shank & older For Shanks & olders: Pages to Various standards are available. Modular system, yet ccurate repeatability of m or less Modular system presetting is possible by provides: boring head alone. Using the same head and shank, assembly and disassembly always locates the cutting edge to the same position within the tolerance of only m. Repeating this procedure many times with the same results proving boring accuracy is high and stable. Repeatability Within m Extension Reduction Chamfering Tool Due to the high accuracy of the Connection design, presetting job can be done with only the boring head. It is not necessary to carry a heavy tool and you can reduce your operation and set-up time. lso, you can prepare for many boring heads set to different jobs in advance for total operation efficiency. We recommend our Presetter for this. (BBT) Presetter PZ Dual Contact Spindle System assures the highest rigidity possible in high speed and difficult metal machining applications.
