gear hobbing machine

Introduction to Machine Tool

The N60J CNC hobbing machine is a CNC hobbing machine with 5 servo control axes and four linkage functions. It adopts the Chinese Heidemeng CNC system and is equipped with a human-machine interaction interface. The various motion axes of the machine tool, including the B, C, X, Z, and Y axes, are all controlled by CNC, and the B, C, X, and Z axes can be linked together. The tooth splitting motion, feed compensation motion, and differential feed compensation motion during the gear cutting process are completed by the software electronic gearbox (EGB), which greatly shortens the transmission chain. After adopting semi closed loop or fully closed loop control, numerical control compensation can improve the positioning accuracy and repeatability accuracy of each axis, thereby enhancing the machining accuracy and Cp value of the machine tool, and improving its reliability. This machine tool can process gear shafts and gears (including straight teeth, helical teeth, drum teeth, synchronous teeth, spline teeth, worm gears, bevel teeth, etc.) through expansion or division, and is widely used in industries such as robotics, aerospace, automobiles, smart homes, power tools, reducers, medical equipment, etc.

structural characteristics

⊙ Multi axis linkage: It has 5 motion axes and supports four axis linkage, enabling complex motion control. For example, the axial and radial feed of the rolling cutter, as well as the rotation and indexing of the workpiece, can achieve precise coordination and can process various types and precision requirements of gears.

⊙ High speed cutting: Using high-performance precision spindles, it can achieve high cutting speeds, effectively shorten processing time, and greatly improve production efficiency.

⊙ High precision transmission: Equipped with high-precision and high rigidity transmission components such as ball screws, linear guides, bearings, spindles, etc., it can ensure high-precision motion of each axis and the ability to handle complex tasks, thereby improving the machining accuracy of gears.

⊙ High degree of automation: It can be equipped with various automatic loading and unloading devices to achieve automated production of gear processing, reduce manual intervention, and improve the consistency and production efficiency of processing quality.

Processing advantages

⊙ High precision: capable of achieving level 6 machining accuracy according to GB/T10095-2008, it can meet the needs of fields with high gear accuracy requirements such as automobiles, reducers, medical devices, robots, etc.

⊙ High efficiency: The characteristics of high-speed cutting and multi axis linkage make the machining process more efficient, and complex gear machining can be completed in a shorter time.

⊙ Wide range: capable of processing gears with various tooth shapes such as straight teeth, helical teeth, and drum teeth, as well as various gear components such as worm gears and gear shafts, with a wide range of applications.

Machine tool operating system

Adopting the Chinese Heidemeng HI102M CNC system, with a fully Chinese operation human-machine dialogue interface (English version available for ordering), the machine tool's various motion axes are CNC controlled and B, C, X, Z are linked axes. The electronic gearbox (program) completes the tooth splitting motion, feed compensation motion, and differential feed compensation motion during gear cutting, increasing the machine tool's functions (such as rolling small taper and drum shaped gears, which become extremely simple); Shortening the transmission chain and adopting semi closed loop or fully closed loop control can improve the positioning accuracy and repeatability accuracy of each axis through numerical control compensation, thereby improving the machining accuracy and Cp value of the machine tool and increasing its reliability; When changing varieties, the time for calculating and changing gear teeth and differential gears, feed and spindle shifting is eliminated, thereby reducing auxiliary processing time and increasing the flexibility of the machine tool;

1. Support OPCDA2.0

2. Support: RS232 and Ethernet data interfaces

3. The machine can perform data monitoring: (The content is as follows)

CNC error number PLC error number Main itinerary number The actual number of loops in the main program The main program preset the number of loops Actual spindle speed Maximum spindle speed The preset speed of the spindle Processing file name Processing file path Zicheng serial number The actual number of loops in the subroutine The subroutine preset the number of loops Actual speed percentage Actual feed rate Actual speed percentage Current spindle magnification Current manual mode Current operating mode Current automatic mode Current operational status When advancing with magnification Display programming coordinates Maximum feed rate Executing machining program Program line number Configure the number of spindles Preset feed rate.

4. NC programs can be directly connected to the CNC system through the network: remote desktop software can be installed on the computer, connected to the machine, and machine data can be remotely monitored, modified, and set.

5. Integration with DNC and MES systems: Open communication interfaces with DNC and MES systems to ensure that the equipment can integrate with DNC and MES systems normally in the future.
