A sander with angular adjustability includes a main body, a workbench, a grinding shaft, a driver, and an angle-adjusting device. The workbench is mounted on a top of the main body. The grinding shaft is rotatably installed on the main body and exposed outside the workbench. The driver is installed in the main body, for driving the grinding shaft to rotate. The angle-adjusting device is configured to be in transmissive connection with the driver. The angle-adjusting device is configured to be switched and operate between a locked position and a released position. In the released position, the grinding shaft has its grinding angle adjustable with respect to the workbench, and in the locked position, the grinding shaft is held at a grinding position by the angle-adjusting device. Thereby, operation of the sander is angularly adjustable to fit different wooden workpieces.

The present invention provides a method for processing a molded tray based on bamboo-wood mixed shavings, comprising: extracting, crushing, mixing, drying, separating by wind separation, heat balance treatment, mixing glue, paving and hot pressing, cooling and grinding, inspecting and warehousing. In the invention, the industrial trays are manufactured by mixed bamboo and wood materials. The bamboo materials do not include bamboo peels and other impurities. The use of bamboo materials can improve the quality of trays from raw materials and reduce the moisture content of the trays. In addition, the brittleness of bamboo materials can improve the hardness of trays. The combined bamboo materials and wood materials can increase the toughness of the product and reduce the cost; furthermore, each link in the production process is elaborately designed and adjusted in the invention. The industrial trays made by the processing method of the present invention have increased the weight supporting capacity by at least 1.5 times compared to ordinary trays, and the product's service life is 3 to 5 years in normal uses (no water soaking, no overpressure).

With the machine, workpieces are machined as they pass through the machine. At least one of the spindles of the machine is coupled with an adjusting unit with which the spindle, for producing a contour on the workpiece, can be adjusted transverse to the throughfeed direction of the workpiece during workpiece throughfeed. The adjustment of the adjusting unit is realized as a function of the advancing speed of the workpiece and/or the workpiece position upon throughfeed of the workpiece. The adjusting unit has such a stiffness and/or low clearance and/or positioning precision that the end products machined from the workpieces after exiting from the machine can be used without further post-machining. The end products have such a geometry precision and surface quality that further post-machining is no longer required.

The angle-adjusting device is configured to be in transmissive connection with the driver. The angle-adjusting device is configured to be switched and operate between a locked position and a released position. In the released position, the grinding shaft has its grinding angle adjustable with respect to the workbench, and in the locked position, the grinding shaft is held at a grinding position by the angle-adjusting device. Thereby, operation of the sander is angularly adjustable to fit different wooden workpieces.
