（1) Workbench base: The material of the workbench base is HT250 material, which has undergone thermal aging and stress relief annealing treatment. The base design adopts symmetrical reinforcement technology to ensure the stability of the equipment foundation.

（2）. Workbench: The workbench material is HT300 material, which has undergone thermal aging and stress relief annealing treatment. The large gear used in the work is made of 45 steel that has undergone quenching and tempering treatment for precision hobbing. The main shaft bearings come standard with P5 grade produced by ZWZ, the main shaft manufacturer. The workbench design adopts symmetrical reinforcement technology, finite element analysis, mature and stable.

(3). Transmission: The worktable adopts continuously variable transmissionThe motor is a spindle specific type with rated power11Kw, The worktable speed range is 0.1-350r/min.

（4）. Bed frame: The bed frame is made of HT250 material and undergoes stress relief annealing treatment through thermal aging,The bed guide rail is subjected to ultrasonic quenching treatment with HRC50 or higher, followed by grinding treatment after quenching.The column is a monolithic structure made of high-strength, low stress cast iron and equipped with effective vibration reduction measures. The combination of the column and the worktable base greatly improves the overall rigidity and reliability of the machine tool.

（5) Horizontal Beam (Fixed Horizontal): The horizontal beam is made of HT300 material and undergoes stress relief annealing treatment through thermal aging,The crossbeam guide rail has undergone ultrasonic quenching treatmentHRC50 or above, quenched and ground.The crossbeam is fixed and locked onto the bed.

Horizontal ball screw for crossbeam（X-axis) P3 level heavy-duty advanced product, with screw support using high-precision bearings specifically designed for screws, featuring high precision, strong rigidity, and long-lasting accuracy retention. The appearance of the crossbeam adopts a white steel protective cover, which is beautiful and generous.

（6）. Beam slide seat: The beam slide seat is made of HT250 material and undergoes thermal aging stress relief annealing treatment. The beam slide seat is installed on the beam, and the sliding friction surface in contact with the beam is treated with plastic tape (including the sliding friction surface of the pressure plate and the inclined iron friction surface) to reduce the friction coefficient and greatly extend the service life.

（7）. Rotary slide seat: The rotary slide seat is made of HT250 material, which has undergone thermal aging and stress relief annealing treatment. The rotary slide seat is installed on the crossbeam slide seat, and the sliding friction surface in contact with the vertical tool holder is treated with plastic tape (including the sliding friction surface of the pressure plate and the inclined iron friction surface) to reduce the friction coefficient and greatly extend the service life.

（8) Sliding pillow: The sliding pillow is made of HT300 material and undergoes stress relief annealing treatment through thermal aging,The slider guide rail has undergone ultrasonic quenching treatmentHRC50 or above, quenched and ground.The structure is a square slider, and the processing accuracy of the slider is0.02mm/1000, The total length is 0.02mm. The vertical ball screw of the slider (Y-axis) adopts P3 grade heavy-duty advanced products, and the screw support adopts high-precision bearings specially designed for screws, which have the characteristics of high precision, strong rigidity, and long-lasting accuracy.

（9）. Hydraulic system:The main control components of the hydraulic system are all products from well-known domestic and foreign manufacturers, with reliable performance. The main function of this system is to:① Provide variable speed power to the hydraulic cylinder of the main transmission gearbox; ② To supply oil to the workbench guide rail device; ③ Supply oil to the balance cylinder of the slider; ④ Supply oil to the crossbeam clamping oil cylinder system; ⑤ Lubrication and oil supply related to machine tools.

（10）. Machine tool lubrication system: Each sliding part of the machine tool is automatically timed, quantified, and supplied with oil by an automatic lubrication pump, and the oil supply time is automatically controlled by the system PLC.

（11）. Electrical system: The electrical cabinet is equipped with refrigeration and air conditioning, and the button station cantilever is installed on the machine tool. The button station and cantilever can rotate at any angle, which is beautiful and easy to operate. All electrical components are made of Tianshui 213 products, which are durable, safe and reliable. The manual feed of the X and Z axes of the machine tool is achieved by operating a handheld unit. The button station is equipped with three color lights to indicate the operating status of the machine tool. The standardized power distribution process, reliable electrical components, and comprehensive PLC programming effectively ensure an extremely low failure rate. Our company solemnly declares that the electrical system is completely independently designed, constructed, debugged, and serviced (not outsourced) by our company, effectively ensuring product quality and solving users' worries.
