The grinding machine is equipped with two grinding spindles. Depending upon the various material of components and different technologies for both rough and fine grinding, the machine comes with a number of optional wheels with diverse material, linear speed, feed speed and grinding processes, which greatly enhances efficiency and precision of components during processing. The X-axis can be driven by an optional linear motor. The C-axis is driven directly by servo motor, which reduces transmission error and greatly improves the profile. The X-axis can be equipped with linear encoder. The spindle is configured in various rotating speed from 24000 rpm to 48000 rpm based on the particular demand.
The grinding machine is equipped with the structure of fixed immobile grinding wheel, the workpiece is installed vertically and moved left and right to process. The workpiece adopts the upper end face automatic compression mechanism for clamping that is convenient of mounting and dismounting. The workpiece performs an action of reciprocation with the grinding wheel, the external and the side of which are dressed automatically. The positioning can be chosen to process each slot or one slot according to the different requirement.
The grinding machine is equipped with one or two spindles in the various kinds of configuration. Depending upon the various material of components and grinding technologies, the machine comes with a number of optional wheels with different material, linear speed, feed speed and grinding processes, which greatly enhances efficiency and precision of components during processing. The internal bore can be grinded for range from diameter 4mm to 50mm according to the different configurations and compositions. Not only single step through hole and bore but also multi-step hole and bore enable to be grinded at the same time in one clamping. The spindle rotating speed range could reach from 36000 rpm to 120000 rpm based on the particular configuration.
The grinding machine has high-strength cast iron base frame. The critical iron castings are conducted a finite element structural analysis. All castings are carried out double aging treatment and vibratory stress relief to ensure the stability of machine accuracy.The upper plate, lower plate and inner ring are driven by three sets of precise worm gear reducers and separate variable frequency motor. The maximum speed for both of the upper and lower plate is 120 rpm, which not only guarantees the stability for quality of the part processed, but also greatly enhances the processing efficiency.CBN grinding wheel with dressing rings.100% in process measurement by SONY sensor with 0.001 mm accuracy ensures the dimensional stability of each batch.
The machine is equipped with a full CNC 7 axises and 4 axises linkage,using the principle of generating method,realize the indexing and differential compensation movement by the CNC system electronic gearbox function,it can complete the processing of cylindrical spur gear,helical gear,small tcone gear,drum gear,spline,worm gear,sprocket and other gear tooth processing.
The machine is equipped with a two coordinate & two axis linkage and semi closed-loop and adopts horizontal bed and large-span rolling guide rail support structure (X/Z axis: 550/300mm), with good dynamic characteristics, strong rigidity and good chip removal performance. It is widely used in machining of automobile, petroleum, military industry and other industries. It can realize the machining of internal and external surfaces, conical surfaces, circular arcs, threads, boring and reaming of shafts and discs.
