Cylindrical Gear Hobbing Machine Technical Parameters
Cylindrical gear hobbing machines are specialized machines used for cutting cylindrical gears. These machines are used in a wide range of industrial applications, from automotives to aerospace, and are widely used for precision gearing operations. The machines can be used to cut both internal and external gears, and can cut gears with a variety of different pitches and diameters. Here we will cover some of the key technical specifications of cylindrical gear hobbing machines to help you understand their capabilities and limitations.
Cutting speed
Cutting speed indicates the speed of the hob, or the number of teeth per minute that the machine can cut. The cutting speed of different models of cylindrical gear hobbing machines varies, but typically the higher-end models can reach up to 2700 teeth per minute when cutting gears with a diameter of up to 250 mm.
Gear accuracy
Gear accuracy is the standard measure of precision for any gear hobbing machine, and it is typically expressed as the difference between the actual gear size and the target gear size. The accuracy of a cylindrical gear hobbing machine typically varies between 0.5 and 0.15 microns.
Power
The power of a cylindrical gear hobbing machine is typically measured in kW, and is a measure of how much torque the machine can generate. The power of the machine will vary depending on the size of the gears being cut, but typically it is around 7-8 kW.
Number of teeth
The number of teeth is an important factor to consider when choosing a gear hobbing machine, as it indicates how many teeth can be cut in one pass. The higher-end models typically have a capacity of up to 500 teeth, while lower-end models can only cut up to 250 teeth.
Feed rate
Feed rate is an important metric to consider when selecting a gear hobbing machine, as it influences the speed of the process. Feed rate is typically measured in millimeters per minute and is usually adjustable, allowing for finer control over the cut.
These are just a few of the key specifications of cylindrical gear hobbing machines. Other metrics that should be taken into account when selecting a hobbing machine include the overall size, the maximum depth of cut, and the hob material. By understanding these metrics, and analyzing them in comparison to the unique requirements of your application, you can select the right machine and ensure that it is able to properly and accurately cut gears to the desired specifications.
