CRL52MSE, the new flagship dual-spindle turn-mill composite lathe under the COORAY Lathe SERIES by Foshan Kurui Machinery Co., Ltd., is officially released. Boasting dual-spindle coordination, multi-process composite machining capability and thermal shock resistant design, this equipment delivers a more efficient solution for precision component machining in the automotive, electronics, medical device and other sectors.
As a top-tier Chinese manufacturer of oil seal lathes, Kurui Machinery has deep roots in the industry for years, earning wide recognition as a trusted oil seal lathe factory, manufacturer and supplier in China. Its COORAY Lathe SERIES is even recognized as one of the best oil seal lathe brands in the industry. The launch of the CRL52MSE marks a significant expansion of the COORAY Lathe SERIES product line and further equips Kurui Machinery with a core competitive edge among oil seal lathe manufacturers and factories.
I. Dual-Spindle Coordination, Breaking New Ground in Efficiency
The standout feature of the CRL52MSE lies in its main and secondary dual-spindle design, with both spindles equipped with permanent magnet synchronous direct-drive motors, enabling full-process machining of components in a single clamping. The main spindle is fitted with an A2-6 8-inch chuck, while the secondary spindle is equipped with an A2-5 6-inch chuck and features an effective stroke of 540mm. It can directly take over components machined by the main spindle to complete subsequent processes without secondary clamping, drastically reducing process changeover time and positioning errors. Paired with a BMT45 power turret and a 5000rpm power head motor, it supports multi-process composite machining including turning, milling, drilling and boring. It is particularly suitable for precision components requiring double-end machining such as shaft and disc parts, boosting machining efficiency by more than 30% compared with traditional single-spindle equipment.
In addition, the equipment is equipped with a precision VDI turret system, which further enhances machining flexibility and accuracy. This makes the equipment not only outstanding in the field of oil seal lathes but also adaptable to diverse precision machining scenarios.
II. Robust Configuration, Ensuring Stable Precision
The CRL52MSE adheres to the high-spec process standards of the COORAY Lathe SERIES, with every detail from core components to structural design engineered to guarantee long-term stable operation:
High-rigidity structure: The bed is made of HT300 integral cast iron, subjected to tempering and over 90 days of natural aging treatment. Combined with a thermal shock resistant design, it maintains stable precision during prolonged high-load machining.
High-precision transmission system: Equipped with PMI & KET P-class guide rail pairs and C3-class ball screw pairs, the X/Z1/Z2 axes achieve a repeat positioning accuracy of ±0.002mm with a minimum setting unit of only 0.001mm, ensuring micron-level machining precision.
Thermal deformation resistant design: Fitted with a patented oil-cooled hydraulic station and liquid-cooled axial motor, it effectively controls equipment temperature rise, mitigates thermal deformation and significantly extends the service life of motors, ball screws and bearings.
These solid configurations have established Kurui Machinery as a benchmark forhigh efficiency and precisionamong Chinese oil seal lathe brands, making it a reliable oil seal lathe manufacturer for customers at home and abroad.
III. Flexible Customization, Adapting to Diverse Scenarios
In addition to its outstanding hardware performance, the CRL52MSE supports flexible configuration customization:
Different spindle and turret configurations can be selected according to production needs, and personalized adjustments to machining length and spindle through-hole diameter are available, adapting to both small and medium-batch custom production and large-scale assembly line operations. The appearance can also be customized based on customers' workshop layout and brand visual requirements, ensuring the equipment integrates seamlessly into the production environment.
