Turning inner and outer cylindrical surfaces and planes;

Turning inner and outer conical surfaces;

thisLarge castings for machine tools are processed using high-quality casting techniques and then subjected to heat aging treatment after rough machiningScientific elimination of internal stress; Small and medium-sized castings are subjected to heat aging, and all steel parts are quenched and tempered The sliding surface of the machine tool is treated with plastic coating, which improves the wear resistance by more than 5 times and increases the precision retention of the guide rail The crossbeam and crossbeam slide are equipped with independent automatic centralized lubrication devices, and the electrical components are selected from Tianshui 213 Electric The main shaft bearing uses tile shaft KaiweiproductionP5 grade bearings, other bearings use tile shafts and products from Harbin Axle Factory

Single column vertical latheMain structural performance

This machine tool consists of a bed, base, worktable, crossbeam, crossbeam lifting mechanism, stand tool holder, gearbox, feed box, electrical cabinet, etc.

（1) Workbench base: The material of the workbench base is HT300 material. The base design adopts symmetrical reinforcement technology to ensure the stability of the equipment foundation.

（2）. Workbench: The workbench material is HT300 material,The workbench adopts a spindle structure, and high-precision thrust ball bearings are used radially to provide directional load-bearing functionAdopting double row cylindrical roller bearings for centering. Its inner ring has a 1:12 taper, which can adjust the radial clearance to ensure the rotation accuracy of the worktable.The material of the worktable spindle isQT500 material, all of which have undergone heat aging and stress relief annealing treatment. The working large gear is made of 45 # steel and precision hobbing has undergone quenching and tempering treatment. The main shaft bearing comes standard with NN3000 series tile shaft and Kewei P5 grade. The workbench design adopts symmetrical reinforcement technology, finite element analysis, mature and stable. The workbench is equipped with four manual claws.

(3). Transmission: The worktable adopts a 16 speed transmission, and the worktable speed range is 3.2-100r/min. The gearbox gears are made of 40Cr ground gears (6th level precision) produced by Shenyang Machine Tool Co., Ltd. Gear Branch, and the spiral bevel gears are made of 20CrMnTi carburizing and quenching grinding process (6th level precision), so the worktable rotation noise is particularly low. The gears and spiral umbrellas can be separately accompanied by the manufacturer's certificate of conformity.

（5）. Bed: The bed is made of HT250 material. The processing accuracy is 0.02/1000mm, with a total length of 0.02mm. The bed is connected to the worktable base. The bed design is mature, stable, and has sufficient rigidity.

（6) Beam lifting: The beam lifting adopts turbine lifting and T-shaped screw lifting mechanism, and there is a hydraulic locking mechanism on the beam. The hydraulic lever wedge block mechanism with self-locking function is used to clamp and interlock with the beam movement, firmly locking the beam on the column. The lifting of the crossbeam is equipped with dual limits of mechanical and electrical soft limits, ensuring safety and reliability.

（7) Beam: The beam is made of HT250 material.The crossbeam moves vertically up and down on the column guide rail. A worm gear reducer and lifting screw are driven by an AC motor. The crossbeam is clamped by a wedge ironRelax. Clamping is achieved through hydraulic means.

（8）. 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.

（9）. 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.

（10) Sliding pillow: The sliding pillow is made of HT300 material, which has undergone thermal aging and stress relief annealing treatment. The structure is a square sliding pillow, with a processing accuracy of 0.02mm/1000 and a total length of 0.02mm.

（11）. Electrical system: The button station cantilever is installed on the bed, and the button station and cantilever can rotate at any angle, which is beautiful, elegant, and easy to operate. All electrical components are made of Tianshui 213 products, which are durable, safe and reliable. 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.

（12）. Machine tool 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 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.

（13）. Machine tool lubrication: The machine tool adopts centralized fixed-point automatic oil supply lubrication for beams and other moving parts.

（14）. Machine tool protection: The moving parts of the machine tool are equipped with comprehensive safety interlocks and interlocks.
