Koepfer's Heavy Duty Hobbing Machine Offers Extended Part Size Capacity
June 6, 2007—The Heavy-duty Model 300 from Koepfer America provides for a bigger part diameter, coarser diametral pitch, and bigger hob capacity than traditional Koepfer hobbing machines.
According to Koepfer's press release, the Model 300 is equally suited to handle both the traditional Koepfer parts, as well as, the new increased capacity workpieces.
The Model 300 has nine axes of CNC control with the gantry loading system, allowing for nearly all (parallel-axis or cylindrical) gear cutting applications, including the timing of one gear to another on the same workpiece and the timing of a gear tooth to an external or internal feature.
The Model 300 provides a maximum module of 4.0 mm (6.35 DP) with a maximum workpiece diameter of 195 mm (7.677"), and a maximum workpiece length of 500 mm (19.685") when manually loading (300 mm or 11.811" with automatic loading).
The design concept of symmetrical distribution of cutting forces ensures a longer machine life with consistent part quality. The slant design of the hob head provides optimum chip flow for dry or wet cutting.
Some other features of this machine include a composite epoxy bed, ensuring the highest possible static, dynamic, and thermal stability; direct drive digital work and cutter spindles, providing consistency and accuracy over the life of the machine; quick clamping work and cutter spindles for quick changeover; full color control panel with TFT touch screen; and optional CNC controlled gantry automation system.
