准备工作：在进行切割之前，确保准备好所需的工具和设备，如电锯、切割机、量具、眼镜等。同时，清理工作区域，确保周围没有杂物和障碍物。

Preparation work: Before cutting, make sure to prepare the necessary tools and equipment, such as electric saws, cutting machines, measuring tools, safety glasses, etc. At the same time, clean the work area and ensure that there are no debris or obstacles around it.

测量和标记：使用量具测量门套的尺寸，并在石塑门套上做出标记，以指导切割的位置和长度。使用直尺或者模板来确保标记的准确性和一致性。

Measurement and marking: Use measuring tools to measure the size of the door jamb and make markings on the stone plastic door jamb to guide the cutting position and length. Use a ruler or template to ensure the accuracy and consistency of markings.

选择合适的切割工具：根据门套的厚度和材质，选择合适的切割工具。对于较薄的石塑门套，可以使用手持电锯或者切割机进行切割。对于较厚的门套，可能需要使用更强力的电锯或者的切割设备。

Choose the appropriate cutting tool: Based on the thickness and material of the door pocket, choose the appropriate cutting tool. For thinner stone plastic door jambs, a handheld electric saw or cutting machine can be used for cutting. For thicker door jambs, it may be necessary to use a stronger electric saw or professional cutting equipment.

操作：在进行切割之前，戴上眼镜和手套，确保自身。将门套稳定固定在工作台上，以防止移动或晃动。在切割过程中，保持稳定的手势和均匀的切割速度，避免突然用力或者过快的切割。

Safe operation: Before cutting, wear safety glasses and gloves to ensure personal safety. Stabilize and fix the door cover on the workbench to prevent movement or shaking. During the cutting process, maintain stable gestures and uniform cutting speed to avoid sudden force or excessive cutting speed.

切割技巧：根据标记的位置，将切割工具沿着门套的边缘或者指定的线条进行切割。对于直线切割，可以使用导轨或者直尺来保持切割的准确性和平直度。对于曲线或者弯曲的切割，需要更加小心和耐心，逐步进行切割，以保持切割线的平滑和精确。

Cutting technique: According to the marked position, use the cutting tool to cut along the edge of the door jamb or the specified line. For straight cutting, guide rails or rulers can be used to maintain the accuracy and straightness of the cutting. For curved or curved cutting, it is necessary to be more careful and patient, gradually cutting to maintain the smoothness and accuracy of the cutting line.

整理和修整：完成切割后，检查切割线的质量和准确性。如果有需要，可以使用砂纸或者锉刀对切割边缘进行修整和打磨，使其更加平滑和整齐。

Sorting and trimming: After completing the cutting, check the quality and accuracy of the cutting line. If necessary, sandpaper or a file can be used to trim and polish the cutting edges to make them smoother and more neat.
