 CNC Gear Grinding Machine

CNC Gear Grinding Machine, Model YK7640

Product Features
1. The CNC gear grinding machine utilizes a modular design with consideration to numerous factors including: thermal equilibrium, temperature influence, and structure optimization, all in order to obtain the best possible performance.
By using a Rexroth IndraMotion MTX micro system, a stable and reliable performance is carried out. The grinding spindle is driven by a powerful built in motor with a maximum power of 15kw in order to achieve a cutting speed of 60m/second.
2. The work table is driven by high precision worm gears that offer a high rigidity and precision. The table is also designed with a dampening mechanism.
3. Axial cutting tool movement, combined with a wider grinding wheel allow the machine to dress up to 20 different wheel shapes at one time, so that the frequency of wheel dressing and wheel changeover is significantly reduced, leading to a higher productivity.
4. A closed circuit control, combined with a featured dressing unit enables the grinding wheel to perform any contour of wheel dressing.
5. A builtin temperature sensor combined with special software ensure consistency and accuracy of the machine.
6. Application of an infinite element analysis achieves a high stability in the machine structure, and all base castings are made of high performance, heat treated gray iron in order to obtain an excellent rigidity and reliability. A state of the art wheel spindle design allows for high speed grinding.
7. A special interface with manual input allows for easy operation, and different parameter combinations are preset for selection. The signal status can easily be checked on the operation panel for easy and convenient maintenance.
8. An online remote diagnosis function is available.
9. The machine is designed to fit a wide range of applications, including grinding internal cycloid wheels within a specification of No. 7. Spur gear grinding is achieved after changing to a special profile grinding software.
10. The compact design is great for easy installation in a small floor space, and the high rigidity fits both small and large batch production.
11. The machine is completely enclosed.
12. The simple and compact enclosure design features a built in hydraulic and piping system.
