Gear Honing Machine

Gleason Works (India) Pvt Ltd offers a Gear Honing Machine, Model 150SPH Spheric, for honing with small axis intersection angles. This is used, among other things, for machining gear teeth with an interference contour. Results are now being achieved here that were previously unimaginable. Workpieces of this kind can only be finished by shaving or honing. Normally, axis intersection angles of 10 to approximately 20 degrees are used for honing, since this process only requires a small tool overtravel and, despite this, an adequate cutting speed is achieved. However, as a rule, only an axis intersection angle of approximately 3 to 3.5 degrees is technically feasible for parts with adjacent gear-shift toothing, which means that the cutting speeds achievable are reduced. However, the 150SPH opens up new possibilities. Of course, this machine is also subject to the geometric limitations of the workpiece but since the 150SPH works at workpiece revolutions of up to 3000 rpm and is also very stable in its structure, it can also run at cutting speeds, which result in a highly economic process. While dressing cycles of approximately 50 parts were previously normal for parts of this kind, 180 to 200 parts can be processed without any dressing using the 150SPH, which means that the tooling costs are reduced by up to 75 Percent. A workpiece with a module of 1.5 mm and 35 teeth only requires 29 seconds floor-to-floor-time. At the same time, the removal rate per flank amounts to 70 Micro mtr/flank at an axis intersection angle of 3.4 degrees.
