5. CNC high-speed vertical lathe
Jiahua CNC high-speed vertical lathe products cover the full range of 400-3000 products. The product is mainly used in industries such as energy, petrochemicals, rail transit, engineering machinery, new energy vehicles, medical machinery, bearings, semiconductors, and 3C.
Bed frame
Advanced reinforced cast iron integrated molding, symmetrical, box shaped, and highly rigid structure with reinforced mesh ribs, capable of withstanding gravity compression and resisting deformation. The reinforced structure of the rice shaped rib plate can resist bending, thermal deformation, and torsional forces, while achieving seismic resistance and enhancing rigidity. After the casting is completed, it undergoes a tightly controlled annealing process to eliminate internal stress and reduce creep effects.
Column
Advanced reinforced cast iron box structure with increased length to width ratio section coefficient and reinforced mesh rib plates on the inner wall.
The rice shaped rib plate enhances rigidity, can resist cutting lateral forces, resist torsional forces, and has the effect of shock absorption and strengthening rigidity. After the casting is completed, it undergoes a tightly controlled annealing process to eliminate internal stress and reduce creep effects.
Saddle (X, Z axis seat)
Advanced reinforced cast iron, the assembly of all track slides and sliding tables, the material is annealed to eliminate stress and prevent the influence of creep. Structural castings that are resistant to torsional and cutting forces.
High strength spindle head
The spindle adopts high-precision angular ball bearings and NN series ball bearings, with excellent radial and axial rigidity accuracy for clamping and positioning. Lubricate with specialized grease to effectively control heat generation, suppress thermal deformation, and ensure the durability and stability of the spindle. Assemble in a constant temperature chamber, pass the test, and then send the machine for assembly; Can ensure spindle life, high precision, high speed, and 24-hour continuous operation effect.
Two axis feed system
The servo motor is directly linked with the ball screw, with excellent accuracy and high induction response, ensuring positioning accuracy and repeatability.
The two ends of the ball screw are equipped with heavy-duty high-precision angled ball bearings, also known as bearing preloading and screw preloading, which are assembled based on accumulated theoretical and practical experience to ensure the rigidity, accuracy, and stability of the system.
High speed and high-precision turret
High speed and high-precision convex wheel turret for quick tool change. Using a curved toothed connector for positioning, zero clearance ensures repeatability and positioning accuracy.
Rear mounted chip conveyor and cooling water device
The chip is discharged close to the spindle, and the bed is washed with chip water to quickly remove iron chips and heat to the conveyor, reducing thermal deformation by separating from the main body.
The guide rail and ball screw support bearing seats at both ends. The ball guide screw is equipped with heavy-duty high-precision angled ball bearings at both ends, known as bearing preloading and screw preloading, which are assembled based on accumulated experience from theoretical and practical use to ensure the rigidity, accuracy, and stability of the system.
The control system adopts the latest Fanuc 0iTF control system, which is perfectly combined with Fanuc motors. It can perfectly solve the processing of various complex programs, improve the machining accuracy of workpieces, enhance surface smoothness, and improve machining efficiency. It also adds program pre reading function.
The nameplate clearly identifies the part information, making after-sales maintenance convenient
All parts of the machine tool are processed and assembled to ensure that the quality of the finished product meets the product drawings and relevant technical requirements. Its safety standards comply with the relevant provisions of GB15760-1995 "General Technical Conditions for Safety Protection of Metal Cutting Machine Tools". Its accuracy standard complies with the relevant provisions of ISO 230-1 "General Rules for Machine Tool Inspection".
