The present invention relates to the technical field of stainless-steel plate processing and specifically a high-efficiency cutting apparatus for use in stainless steel plate processing, comprising a left base and a right base. Several support legs are fixed on the bottom of the left base and of the right base. A slidable plate is slidably connected on the left base and the right base. A threaded rod mechanism is connected to the lower end of the slidable plate. A clamping mechanism and a cutting mechanism are connected to the upper end surface of the slidable plate. A stainless-steel plate is provided directly below the clamping mechanism. The stainless-steel plate is placed on a platform. The platform is arranged above the slidable plate. Two support plates are fixedly connected to the lower end of the platform. The support plates are fixed on the left and right respectively on the left base and the right base. The apparatus has high cutting efficiency, is capable of accomplishing greatly corresponding production cutting tasks, and is highly flexible in terms of controlling the orientation and depth of cuts.

An adjustable drilling device for stainless steel plate machining, pertaining to the field of stainless steel plate machining. The adjustable drilling device comprises a top frame (1), a side frame (7), a base plate seat (8), and a machining platform (9). A mounting plate (4) is provided between the top frame (1) and the machining platform (9). The mounting plate (4) is connected and fixed to the top frame (1) by means of multiple telescopic cylinders (2). A fixed pipe is fixedly mounted on the mounting plate (4). A lower end of the fixed pipe is connected to a rotary pipe (13) by means of a rotary body. A driving assembly used to drive the rotary pipe (13) to rotate is further mounted on the mounting plate (4). An adjustable damping fixing assembly (12) is mounted at a lower end of the rotary pipe (13). A drill bit (10) is mounted at a lower end of the adjustable damping fixing assembly (12). An upper end of the fixed pipe is connected to a vacuum pump (16) mounted on a lower side of the top frame (1) by means of a vacuum hose (17). The vacuum pump (16) is used to control the force of relative rotation between the rotary pipe (13) and the adjustable damping fixing assembly (12). The drilling device facilitates adaptive and dynamic adjustment of drilling torsion force, improves the quality and efficiency of drilling-based machining, and extends the service life of the drill bit.
