The meaning of the center height of the inclined rail lathe

The center height of the inclined rail lathe refers to the distance between the centerline of the tool holder and the centerline of the workpiece. The purpose of adjusting the center height of the inclined rail lathe is to ensure accurate dimensions and good surface quality of the machined parts, thereby ensuring production efficiency and product quality.

Secondly, adjustment methods

1. Measure the initial center height: First, measure the initial center height of the inclined rail lathe for subsequent adjustments. Use a radioactive detector or calibration rod to measure the distance between the centerline of the tool holder and the centerline of the workpiece, and obtain the initial center height value.

2. Adjusting the spiral gear: The spiral gear of the inclined rail lathe is the key to controlling the up and down movement of the tool holder. When adjusting, the spiral gear should be loosened first, and then fine tuned according to actual needs, so that the two centerlines of the tool holder remain horizontal when moving up and down.

3. Adjusting the workpiece clamping method: If the workpiece clamping method is incorrect, it can also lead to inaccurate center height. It is necessary to check whether the clamping method is correct. When clamping the workpiece, it is also necessary to ensure that the center of the workpiece coincides with the centerline of the lathe bed.

4. Check the spindle bearings: If the spindle bearings of the inclined rail lathe are damaged or excessively worn, it will cause displacement between the spindle and the tool holder, resulting in inaccurate center height. At this point, it is necessary to replace the spindle bearings and perform a new overall debugging.

Thirdly, precautions

1. When adjusting, power off first to prevent accidents.

Before adjustment, a comprehensive inspection of the entire lathe should be conducted to ensure that all components of the inclined rail lathe are in normal condition.

3. Do not make excessive adjustments to avoid affecting the lifespan and performance of the lathe.

After debugging is completed, conduct a test run to check if the entire machine is adjusted accurately. If necessary, make further adjustments.
