Product Description
This machine tool is equipped with a Siemens 840D SL CNC system, featuring eleven axes and five-axis simultaneous control. The grinding wheel profile is dressed using a single diamond dresser with double-sided dressing, enabling automatic adjustment of the pressure angle; the outer circumference of the grinding wheel is dressed with a carbide blade, significantly enhancing dressing efficiency. The machine supports automatic workpiece clamping, automatic and uniform distribution of grinding allowances, automatic tool setting and engagement, and employs multi-head grinding wheel technology. It also utilizes in-phase dressing technology, which facilitates high dressing accuracy; moreover, the dressing position is lower than the workpiece clamping position, effectively preventing dressing debris from compromising clamping accuracy. The machine adopts a design philosophy emphasizing thermal symmetry, high rigidity, and lightweight construction, thereby enhancing machine stability, machining efficiency, and machining accuracy.
This machine tool is a high-efficiency, high-precision worm-wheel grinding machine specifically developed for industries such as automotive, construction machinery, and gear reducers. It is suitable for the mass production of high-precision involute cylindrical gears with module ranging from 1 to 6 and diameters up to 300 mm. With the goals of high precision, high efficiency, and high reliability, the machine incorporates features such as universal dressing, tooth-surface anti-torsion, and single-sided dressing, thereby meeting the stringent requirements in gear drives for transmission accuracy, noise reduction, and improved transmission efficiency. The machine adopts a vertical configuration and consists of key components including the bed, large column, slide block, grinding-wheel slide, workpiece spindle, grinding-wheel spindle, workpiece column, tailstock, loading/unloading mechanism, and feed drawer.
