Machining Has Never Been This Efficient
We can meet all your machining needs for large, heavy workpieces.
Let us relieve the pressure of achieving the required machining precision, so you can fully enjoy the benefits of high-efficiency machining!
Milling Instead of Grinding,
Surface accuracy and smoothness rival those of grinding machines
High-speed cutting technology and advanced cutting parameters; no compromise on surface quality or accuracy; offering faster machining speeds and potential cost savings, making it the preferred solution for your precision machining needs.
A. Spindle
The machine features a high-rigidity mechanical spindle and a two-speed gearbox to deliver greater cutting torque, meeting the demands of heavy-duty machining at low speeds with high torque.
The optional electric spindle ensures smooth operation and high surface finish on machined parts, while providing more stable and reliable compatibility between the cutting tools and the system.
B. High-Speed Nut Rotation Drive Technology and Direct-Drive Technology
- The machine tool offers an optional three-set ball screw configuration, utilizing the company’s innovatively optimized ball screw-rotating nut drive structure, which features low rotational inertia, minimal heat generation, high drive efficiency, and excellent dynamic response performance.
- The machine tool offers optional direct-drive technology for the X and Y axes.
C. Optional Encoder-Based Synchronous Control
- When the X-axis uses a dual-drive configuration and the Y-axis uses a single-drive configuration, full closed-loop control via an encoder scale must be employed, significantly improving measurement sampling speed, measurement accuracy, and control of vibration interference.
D. Optional Direct-Drive Motor Synchronous Control Technology
- When the X-axis uses dual-drive and the Y-axis uses single-drive, full closed-loop control via a linear encoder must be employed, which significantly improves measurement sampling speed, measurement accuracy, and control of vibration interference.
Full-process In-house Design & Production
Starting from Casting Design
Up to Customer Production Implementation
Let’s See How We Do It？
For example, castings from Changzhou Yongjin Equipment: applied according to design drawings, they must withstand high-impact, vibration, and tensile forces without deformation.
- Casting Material: GB standard HT300; no porosity, sand holes, cracks, or other casting defects allowed
- Castings are stress-relieved by annealing, followed by manual vibration to remove residual stress; stamped with serial numbers
- Casting material density and hardness are balanced; six points are measured on each casting, all must be HB200±5%
- Surface roughness complies with GB/T6060.1, and casting surface evaluated according to GB/T15056 reaches Ra25
- Non-machined dimensions per drawing are executed according to casting dimensional tolerance grade CT5
The manufacturing process of CNC machine tools is highly rigorous!
