A calibration method for machine tools comprises: providing a workpiece on a machine tool; rotating the workpiece around a first rotation axis parallel to a main shaft of the machine tool and processing the workpiece by a first machining mode; measuring a first dimensional error of a shape of the workpiece along directions of first and second linear axes perpendicular to the first rotation axis; calculating a positional error of the first rotation axis according to the first dimensional error; rotating the workpiece around a second rotation axis perpendicular to the main shaft and processing the workpiece by a different second machining mode; measuring a second dimensional error of the shape of the workpiece along a direction of a third linear axis perpendicular to the second rotation axis; calculating a positional error of the second rotation axis according to the second dimensional error.

Calibration method and calibration system for machine tools

A monitoring method and a monitoring system for a machine tool to machine a workpiece are provided. The monitoring method includes the following steps. First, a vibration signal of a spindle of the machine tool is detected. Next, a vibration feature value of the vibration signal is obtained. Whether the vibration feature value exceeds a threshold condition is determined, wherein the threshold condition is determined by a training model based on a predetermined surface quality of the workpiece. When the vibration feature value exceeds the threshold condition, a machining parameter of the machine tool is adjusted.

Monitoring method and system for machine tool

A thermal compensation system for machine tools includes a thermal compensation-monitoring device and a cloud processing device. The thermal compensation-monitoring device receives a plurality of temperature signals of a workpiece and corresponding processing tolerance data to build or update a thermal compensation database. The cloud processing device provides a thermal compensation model, and applies the model with the characterized temperature signals and the tolerance data to generate a compensation value so as to decide whether or not to modify the model or to run a compensation is necessary.

A hollow screw cooling device, which has a set of apertures provided on an oil-proof base on the driven end of the hollow screw. By having fixing screws go through the apertures and the through holes on the bearing press board and fixed on the bearing base, the oil-proof base can be fixed on the outer side of the bearing press board. By directly taking off fixing screws, the oil-proof base can be directly taken off the bearing base when maintaining or replacing the seal without disassembling the components such as the bearing and bearing device.
