In the field of precision gear processing equipment, choosing the appropriate CNC vertical gear hobbing machine manufacturer directly affects production efficiency and processing accuracy.
As an enterprise specializing in the R&D and manufacturing of gear processing equipment, Tengsending Machine Tool (Ningbo) Co., Ltd. relies on thirty years of technology accumulation and industrial transformation experience to provide highly reliable and economical solutions for the gear processing industry.

Tengsending Machine Tool was established in 2020. Its predecessors were Taizhou Huadong Machine Tool Co., Ltd. and Shanghai Aolong Machine Tool Factory established in 1996.
This development process reflects the company’s unique strategic path: transforming from a gear processing factory to a gear processing equipment manufacturer.
This transformation has given the team a deep understanding of the process pain points, equipment performance requirements, and actual production scenarios of gear processing.
The corporate team has decades of experience in gear processing and has accumulated technical capabilities in the use, maintenance, and modification of imported and domestic equipment.
This “user perspective” is transformed into product research and development advantages, allowing Tengsending Machine Tool to provide improvement solutions for practical problems of traditional equipment.
At present, the company has a 15-person R&D team and 60 production technicians, equipped with a 33,000 square meter production plant, has passed ISO9001 certification, and has a number of utility model patents.
Tengsending Machine Tool’s CNC gear hobbing machine series covers multiple models, and each product is optimized for different processing needs.
Its technology supports module 6M, processing tooth number range 4-2000z, spindle speed up to 2000rpm, covering cylindrical spur gears, helical gears, worm gears, drum gears, spline shafts, sprockets, synchronous pulleys and other workpiece types.

The main technological breakthroughs of the YK3120 series are significant.
The YK3120 six-axis (four-axis linkage) vertical high-speed CNC gear hobbing machine aims at the pain points of cumbersome and low-efficiency operation of exchanging gears and differential hanging wheels of traditional old-fashioned gear hobbing machines. It uses an electronic gearbox (EGB) to replace the traditional mechanical hanging wheels, which significantly improves the adjustment efficiency.
The workbench uses a high-precision direct drive torque motor to achieve gapless rotation and improve transmission rigidity.
The spindle transmission system is equipped with P3 grade bearings and precision grinding grade ball screws, and is equipped with automatic overload monitoring and alarm devices to ensure the stability of the processing process.
The YK3120-2 model is reinforced and optimized on this basis. The guide rail adopts a hard rail design to enhance the overall rigidity of the machine tool and the wear resistance of the guide rail surface.
The hydraulic, lubrication and cooling systems are completely independently designed to improve system reliability and maintenance convenience.
For different application scenarios, Tengsending machine tools also have adaptation plans.
In response to the needs of high-speed processing of small and medium modules, YK3118 uses heavy-cut roller linear rails to ensure accuracy and stability for long-term processing. Each kinematic pair is equipped with reliable protection or sealing to adapt to high-intensity production environments.
YK3116 simplifies the traditional mechanical transmission chain through dual direct drive motors, improves dynamic response speed, and independently controls axial and radial motion to enhance processing flexibility. It is suitable for application scenarios that require high indexing accuracy.
For workpieces with long shafts or specific clamping requirements, Tengsending Machine Tools provides horizontal structure solutions.
The YK3618 six-axis (four-axis linkage) horizontal high-speed CNC gear hobbing machine adopts a horizontal layout and cooperates with the movement of a large column to achieve radial feed. The layout is compact and adaptable to special workpiece shapes.
Based on the horizontal structure, YK3625 is equipped with a 750mm slide plate stroke to expand the processing size range. The rated torque of the worktable motor reaches 720N.m, ensuring strong cutting capabilities and meeting the processing requirements of larger-sized workpieces.
Tengsending machine tool products provide diversified system options. Users can choose FANUC system, Siemens system or new generation system according to actual needs.
The product supports secondary tool setting functions, automatic loading and unloading functions and other options, adapting to the integration needs of production lines with different degrees of automation.
The company has established standard testing methods and scientific process equipment to provide users with product maintenance and technical support.
This service system is derived from the team’s long-term practice accumulation of equipment maintenance and modification, and can quickly respond to customers’ technical needs during use.
The competitive advantages of Tengsending Machine Tools are reflected in multiple dimensions.
Product design driven by practical experience enables products to focus on solving pain points in real production scenarios; reinforcement and improvement of machine tool components improve machine tool rigidity, precision stability and dynamic response capabilities; modular and individual system architecture reduces fault correlation and improves equipment maintainability; the scene adaptability of the product matrix covers the needs of different production scales and workpiece characteristics.
