There are many brands of lifting indexing dividers, including imported and domestic ones. High cost-effective imported dividers are Taiwan dividers. Their positioning accuracy is ±15 arc seconds, the standard positioning accuracy is ±15 arc seconds~±20 arc seconds, the repeat positioning accuracy is ≤±5 arc seconds, and ordinary precision models can also reach ±30 arc seconds. There is no cumulative error. The larger the turntable, the greater the error. The accuracy of some special models can reach ±15 seconds. The second angle refers to the angle unit. Basically, for example, the positioning error at the edge of a one-meter diameter turntable is about ±0.07mm, and the accuracy detection of the lifting indexing divider -140df-12 station accuracy detection is ±5 seconds.

A lifting indexing divider is a high-precision mechanical transmission component. The accuracy of a lifting indexing divider includes usage accuracy and repeat positioning accuracy. Accuracy depends on the capabilities of the divider manufacturer. In terms of processing equipment and accessories, capable manufacturers are top-notch. Whether the assembly supervisor is professional is also important. As an experienced assembly master, the lifting indexing divider not only has high precision but also no gap.

Of course, this accuracy refers to the accuracy of all divider attachments processed in a standard machining center. Some low-end products are far from reaching this accuracy. This accuracy basically meets the accuracy requirements of most equipment on the market. Since the lifting indexing divider is indexed by a cam, there is no cumulative error, only a positioning error.

Many factors affect the accuracy of lifting indexing dividers. The lifting indexing divider itself is a combination of multiple mechanisms. During installation, motor connection plates, reducers, flanges, and clutches are needed. Gaps exist in these assembly processes, which will also affect accuracy. In addition, input shaft connection, unstable motor, output shaft offset and misalignment. Inaccurate model selection, exceeding the large torque of the divider, loose screws during use, untimely maintenance, etc., will all affect the accuracy of the divider.

When selecting a model of lifting indexing divider, professional personnel need to calculate the dynamic torque and select a suitable model. If the model is too small, it is also greatly related to the accuracy and stability of the lifting indexing divider. Therefore, when selecting a lifting indexing divider, we must find a regular manufacturer for model selection and production. For example, a lifting indexing divider loads a 1-meter diameter turntable at work station 6. When station 1 rotates to station 2 and stops, its positioning error is measured to be offset to the left by 0.07mm. Then, when station 2 rotates to station 3 and stops, its positioning error is also 0.07mm, that is, this position is fixed. If one station is offset to the left by a certain distance, the next station will be offset to the left by a waiting distance. Therefore, for some equipment with higher accuracy requirements, the next workstation can be fine-tuned according to the offset distance, such as equipment for drilling and tapping teeth, and the power head for drilling can be fine-tuned.

Many factors affect the accuracy of lifting indexing dividers, such as the materials, processing technology, mainframe assembly technology, and processing equipment of the various components in the lifting indexing divider. It is the comprehensive coordination of various components to meet the requirements of high precision. When selecting a lifting indexing divider model, professional personnel need to calculate the dynamic torque and select a suitable model. If the model is too small, it will also have a great impact on the accuracy and stability of the lifting indexing divider.
