KX 1 gear centre

generating and profile grinding of gears

machine concept
The KX 1 is an extremely stable, quick and easy to set-up gear centre, enabling continuous generating grinding as well as discontinuous profile grinding.

The KX 1 is mainly designed for hard finishing of external spur and helical gears for medium to high-volume series manufacturing, predominately for the machining of shafts. Workpieces of modules up to 10 mm, of outside diameter up to 250 mm and a flank width up to 450 mm can be ground. Varying workpiece data is considered upon request.

Depending on the definition of the specific task even application-specific solutions can be realised, e.g. the machining of two gears in one single set-up. The KX 1 uses only non-dressable precision hard finishing tools. They consist of a hardened steel base body with a ground base profile and a single-layer galvanic coating of CBN abrasives.

Since the tool spindle can hold several CBN tools, grinding optimisation is possible by the sequential use of roughing and finishing tools in one single workpiece set-up. Alternatively, gears can be machined in one set-up.

A total of six NC-axes aligning gear and tool to each other. They swivel the tool to the axes cross angle and carry out the linear and rotary motions necessary for the machining process. Workpiece and tool are directly driven. The grinding process mostly applied is continuous generating grinding with cylindrical grinding worms. Alternatively, single or multi-set CBN profile grinding wheels can be used for full-form machining.

control and software
The control system Sinumerik 840D sl is equipped with an operator-friendly menu-driven user interface, developed by KAPP NILES to match the specific machining requirements.

Several loading systems can be integrated in the machine installation. Depending on the task definition, the type and volume of the workpiece loading as well as additional functions embedded in the automatic sequence can be freely defined.
