Heavy Duty CNC Gear Milling Machine For Spur/Helical Gear

Acceptance of the Heavy-Duty Gear Milling Machine:

A Smooth and Highly Efficient Collaboration

Just yesterday, we welcomed an important milestone--the acceptance of a new heavy duty gear milling machine designed for large gear processing. As one of the key objectives of the customer's visit to China, this machine acceptance directly affects their future production capacity planning and gear quality improvement. For this reason, we made thorough preparations in advance. From pre-communication, inspection data verification, on-site demonstration, to technical explanations, every step was handled with precision to ensure the gear milling machine could be presented in its best condition.

Before the customer arrived, our technical team worked closely with the factory to confirm every set of inspection data related to the gear milling machine. All records including worktable accuracy, tool arbor accuracy, spindle performance, and system response-were compiled into printed documentation for convenient review. When the customer arrived at the factory workshop, we accompanied them to inspect the heavy-duty gear milling machine up close and observe its structural design and running condition.

Structural Advantages of the Gear Milling Machine-Engineered for Heavy Cutting

The machine bed adopts a rectangular guideway structure featuring excellent rigidity and vibration damping performance. The column uses a double-ribbed design with a bottom locking mechanism to further enhance cutting rigidity. An optional rear-column module is available for machining shaft-type gear components-an option that particularly interested the customer, given the large number of gear shafts they produce.

CNC System with Secondary Development-More User-Friendly Operation

The gear milling machine is equipped with a Siemens CNC system, enhanced with secondary HMI development. After hands-on operation, the customer praised the interface layout, program navigation, and ease of use. They noted that while many machines on the market have strong hardware, few offer such intuitive and efficient software interaction. The user experience of this gear milling machine left a strong impression on them.

Key Structural Features Enhance Accuracy and Stability

The spindle head includes an automatic rotation mechanism for helical gear machining. Its dual-side drive structure ensures high torque transmission, while the hydraulic backlash-elimination system reduces cutting noise and improves gear surface finish. The customer asked several detailed questions about the spindle head and expressed satisfaction with its vibration control and finishing quality.

The rotary table adopts a heavy-duty, high-precision worm-gear design with a locking device that increases circumferential cutting rigidity and suppresses radial and tangential vibration. During simulated cutting, the gear milling machine demonstrated exceptional stability, prompting the customer to remark repeatedly: 'Achieving this level of stability when machining such large parts is truly impressive.'

Complete Machining Workflow: Rough Milling, Semi-Finishing & Finishing

We explained the machine's flexible process configurations:

Rough milling: large cutting depth and high metal removal rate, ideal for rough gear profile shaping.

Semi-finishing: suitable for pre-grinding preparation of hardened components, balancing efficiency and cost.

Finishing: capable of achieving GB Class 8 accuracy, perfectly aligned with customer requirements.

The gear milling machine supports multiple process combinations. From 'rough + finish milling' completed on a single machine, to 'gear milling + gear grinding' for high-precision hardened gears, the process adaptability ensures minimal machine changeover and maximum efficiency.

Smooth Acceptance and Excellent Communication Experience

The acceptance process went very smoothly. After verifying the accuracy and performance of the gear milling machine, the customer stated: 'This machine fully meets our expectations-and even exceeds them in several details.' The inspection was successfully completed within the day.

We then provided the customer with operation videos, machining videos, and trial-cut footage, while also organizing all the photos taken at the workshop for their internal review.

Before the customer left the factory, we prepared an additional set of accessory configurations-tool holders, cutter heads, and consumables as a complimentary upgrade. The customer was pleasantly surprised and expressed genuine appreciation for this thoughtful gesture: 'We are not only satisfied with the gear milling machine, but also with your service.'

A Successful Delivery: A Dual Validation of Product and Service

This acceptance of the heavy-duty gear milling machine is more than just a handover; it represents full recognition of our technical capability, manufacturing strength, and service professionalism. From the preparation of documentation to every detail demonstrated on site, our team ensured a flawless experience.

The customer will return from Shanghai the next day, but has already expressed clear intent to continue purchasing additional machines from our gear milling machine product line. This trust is more than a commercial decision it is an affirmation of our long-term commitment to quality and reliability.

Moving forward, we will continue enhancing the performance, automation, and intelligence of our gear milling machines, providing global customers with more efficient, stable, and advanced gear machining solutions.
