YK3150 CNC Gear Hobbing Machine (Customizable)
◆ Product Presentation
The YK3150 is a 5-Axis CNC Gear Hobbing Machine featuring a five-axis, four-linkage control system. It is primarily designed for machining spur and helical cylindrical gears with a module of ≤6 mm, and it can also process worm gears using the radial feeding method. This machine is especially suitable for the efficient production of spur gears, helical gears, and worm gears across a wide range of industrial applications.
This 5-Axis CNC Gear Hobbing Machine is well-suited for mass production, small-batch manufacturing, and single-piece processing of cylindrical gears and worm gears. It is also capable of hobbing short spline shafts with a cutting length of less than 300 mm and with 6 teeth or more. Additionally, by using a chain wheel hob cutter, the machine can process sprockets. When machining cylindrical gears, both climb hobbing and conventional hobbing methods can be applied, and full tooth width can be achieved through axial (vertical) feeding.
For standard worm gear processing, the 5-Axis CNC Gear Hobbing Machine adopts a radial feeding method to ensure stable and accurate cutting performance. When machining spline shafts and sprockets, the setup and operation procedures are similar to those used for spur gear machining, making the machine easy to operate and highly versatile.
Widely used in industries such as automotive powertrain components, transmission bearings, and high-speed railway balance spline shafts, this machine delivers high-precision performance. Its advanced machining capabilities make it ideal for producing high-precision gears, automotive axle shafts, drive shafts, water pump motor shafts, and other critical mechanical components.

Scraping the contact surfaces between components |
1.After scraping, it can make the surface flatness better, the contact better, and the contact points more. Moreover, it has a certain hardening effect on the surface and enhances the wear resistance. |
|
|
The surface quality of the scraper is evaluated by the number of contact points per unit area, and the standard adopted is 12-16 points /25*25mm. |

2. |
Laser interferometer detection |
It can conduct dynamic characteristic analysis of machine tool ball screws, response characteristic analysis of drive systems, dynamic characteristic analysis of guide rails, etc. It features extremely high precision and efficiency, providing a basis for error correction of machine tools. |
|
|
3. |
Ball screw transmission assembly |
The parallelism between the ball screw and the guide rail is adjusted by grinding the lead screw nut seat during assembly, with the control requirement being 0.01mm/300mm |
|
|
4. |
Spindle Assembly |
The assembly process takes place in a constant-temperature workshop to ensure the accuracy and quality during the assembly process. After assembly, the main shaft needs to be test-run before installation to detect abnormal noise, temperature rise, etc. Only after confirming that there are no problems can it be installed. |
|
|
5. |
The gear inspection instrument examines the precision of the products processed by the gear hobbing machine |
Gear measuring instruments can measure and evaluate various precision indicators of gears in accordance with the provisions of international and national standards. These indicators include tooth profile deviation, helix deviation, pitch deviation, radial runout, etc. |

Mechanical parts
|
1 |
Castings |
The main machine parts such as the bed, column, worktable and hob head are made of high-quality gray cast iron with excellent anti-vibration performance. They are produced by specialized manufacturers certified under the ISO 9000 quality management system. Special processes are adopted in the casting process to enhance the mechanical properties of the material. The castings undergo two aging treatments to eliminate internal residual stress, ensuring good thermal stability and long-lasting dimensional accuracy. |
|
2 |
Hob Spindle |
The machine adopts a self-manufactured hob spindle. The main spindle is produced by a professional spindle manufacturer. After carburizing and quenching, the quenched surface layer possesses compressive stress, which improves its bending strength, featuring rotational accuracy, rigidity, and speed adaptability. High-precision bearings from well-known Chinese brands are adopted for the spindle bearings, ensuring extremely high accuracy and rigidity of the spindle. The entire assembly process is completed in a constant-temperature workshop to avoid accuracy deviations caused by environmental factors. The hob spindle speed is 0–600 r/min with stepless speed regulation.
|
|
|
3 |
Workpiece Spindle (Worktable) |
It adopts high-precision Class 6 double-thread worm gear drive. The worm wheel is made of tin bronze, featuring excellent wear resistance and lubricity. Driven by a servo motor with gear differential reduction, the rotation speed is 0–35 r/min with stepless speed variation.
|
|
|
4 |
Guide Rails |
Hard guide rails are adopted. The contact surfaces between the sliding table and guide rails are hand-scraped to achieve better flatness, improved contact quality and more contact points. The scraping process also provides a certain surface hardening effect to enhance wear resistance. Ball screws are used for transmission. |
|
|
5 |
Tailstock |
The tailstock center is Morse No. 4, adopting hydraulic drive with adjustable pressure. |
|
|
6 |
Hydraulic Power Unit |
The hydraulic system and cooling circulation system are separate to avoid mutual mixing. The hydraulic power unit is equipped with a hydraulic oil level alarm, which alerts the operator when the oil level is too low or too high. |
|
|
7 |
Lubrication System |
Adopts automatic centralized lubrication that supplies oil to the lead screws and guide rails at fixed intervals and in fixed quantities, ensuring sufficient lubrication during machine operation. This guarantees excellent rapid response and low-speed feed performance, prolongs service life, and improves accuracy retention. The system is also equipped with a fault alarm function and can automatically run the lubrication program upon startup. |
|
|
8 |
Chip Conveyor |
A magnetic chip conveyor is adopted, which can handle metal chips, fine iron chips, casting chips and so on. It can also adsorb residues in the cooling oil and collect them on the conveyor, featuring low energy consumption and high efficiency. |
|
|
9 |
Oil Mist Separator (Optional) |
It can effectively remove oil mist, water mist and other contaminants in the air, improve the workshop production environment, extend the service life of equipment and reduce costs. |
|
|
10 |
Electrical Cabinet Air Conditioner (Optional) |
It cools the heat generated by the power consumption of electrical components, providing an ideal temperature and humidity environment inside the electrical cabinet. Meanwhile, it isolates dust and corrosive gases from the external environment, extends the service life of electrical components, and greatly improves the reliability of the machine. |
|
|
11 |
Sheet Metal & Protection Covers |
The machine tool is equipped with a fully sealed protective cover, eliminating pollution to the production environment caused by oil mist or dust during high-speed gear hobbing. With an innovative protective design, the machine resolves oil leakage and seepage issues. In addition, L-shaped sliding doors are adopted for convenient workpiece hoisting, making operation and maintenance of the machine tool easier. |
