gear hobbing machine

Introduction to Machine Tool

The N40 high-speed CNC gear hobbing machine is an advanced high-speed small module gear hobbing equipment. The machine tool adopts a horizontal structure layout, precision casting bed body, and enclosed body cover. Equipped with Higeman control system (or optional FANUC control system), it is operated by 8 CNC control axes, namely B (tool spindle), C (workpiece spindle), C1 (tailstock spindle), A (helix angle rotation axis), X (tool radial feed axis), Z (workpiece axial feed axis), Z1 (tailstock axial feed, can move synchronously with the Z axis), Y (tool movement axis), among which B, C, X, Z are linked; The human-computer interaction interface is easy to operate and does not require complex programming; Based on the principle of generating method, the meshing process of gears is simulated by the relative motion between the rolling cutter and the workpiece, and the gear tooth profile is machined on the workpiece. Accurately control the cutting trajectory of the rolling cutter and the rotation of the workpiece to achieve efficient and high-precision gear machining; The processing accuracy can reach 5-6 levels of GB/T10095-2008, and is widely used in industries such as robotics, aerospace, smart homes, clocks, home appliances, instruments, and medical devices. The design of dual workpiece spindle C/C1 and dual axis feed Z/Z1 structure is particularly suitable for the machining of high-precision small and micro gears and gear shafts (slender shafts can be clamped and tightened by double heads). The machine tool design reserves automatic equipment installation stations and electrical interfaces, which can be matched with various types of automatic loading and unloading equipment.

Structural Characteristics

⊙ The machine tool bed adopts HT300 gray cast iron base, with strong overall rigidity, high wear resistance, good shock absorption effect, two failure annealing+natural failure stress relief, and stable working accuracy; The overall layout of the machine tool is reasonable, with a horizontal spindle layout and a dual workpiece spindle C/C1 and dual axis feed Z/Z1 structure design; Equipped with HigemanHI102M control system (or optional FANUC0i MFPlus control system), it is operated by 8 CNC control axes, namely B (tool spindle), C (workpiece spindle), C1 (tailstock spindle), A (helix angle rotation axis), X (tool radial feed axis), Z (workpiece axial feed axis), Z1 (tailstock axial feed, can move synchronously with the Z axis), Y (tool movement axis), among which B, C, X, Z are linked.

⊙ The machine tool adopts imported precision grade ball screws and high rigidity, high-precision linear roller guides to ensure transmission accuracy and rigidity, and can process high-speed hard tooth surfaces.

⊙ The machine tool spindle and workpiece spindle are both driven by servo motors in a direct connection manner, effectively eliminating errors and clearances caused by mechanical transmission chains, and meeting the high-speed and high-precision machining of various parts.

⊙ The CNC system of the machine tool is equipped with electronic gearbox (EGB) function, human-machine dialogue interface, and does not require complex programming; By entering the corresponding workpiece parameters, rolling cutter parameters, and machining parameters in the interface dialogue bar, the gear machining process program can be implemented, making the operation simpler and faster.

⊙ The machine tool is equipped with an independent quantitative lubrication system to automatically lubricate the workpiece spindle, tool spindle bearings, ball screw, roller linear guide and other moving components in a quantitative cycle, ensuring the working accuracy and stability of each moving component.

⊙ The machine tool adopts a fully enclosed protective cover design, effectively preventing the overflow of cutting fluid and oil stains; Equipped with a circulating cutting cooling system, effectively ensuring the thermal balance of the bed body; Configure a magnetic chip removal machine to remove iron chips, resulting in cleaner and smoother chip removal (copper and aluminum chip removal machines can be customized and selected).

⊙ The electrical system of the machine tool complies with the GB/T5226.1-2019 standard, with a power supply of 380V/50HZ. The electrical control box is located above the rear of the machine tool and is equipped with a constant temperature air conditioning system; The electrical switches, pipelines, and cables are arranged neatly and reasonably, easy to operate, and the overall appearance is beautiful and clean.

⊙ The machine tool is equipped with an oil mist treatment device to recycle and treat the oil mist generated during high-speed cutting, purify the environment, and protect the health of employees.

⊙ Power off protection function: When a fault occurs during the machining process and the emergency stop button is pressed or the power is suddenly cut off, the workpiece and the tool remain synchronized and quickly retract, protecting the tool from collision damage (optional device).
