SR-32JIII Type A/B Questions
Answers to common questions about the SR-32JIII Type A/B.
The primary differences between the SR-32JIII Type A and Type B lie in their backworking attachments and tool capacities. Type A features a 6-tool backworking unit, while Type B is equipped with an 8-tool backworking unit and an additional Y-axis control function. This makes Type B more suitable for complex machining tasks that require additional tooling and flexibility.
The SR-32JIII's modular design significantly enhances its performance by providing increased rigidity and stability, which ensures consistent quality over extended periods of continuous production. This design also allows for versatile machining capabilities, reducing cycle times and increasing productivity. The slanted guideways and dovetail slide ways on multiple axes further improve the machine's accuracy and stability.
The SR-32JIII is capable of machining a wide variety of parts, including small diameter cylindrical bar stock into complex, high-precision components such as small pins, shafts, and screws. It can handle parts with a maximum diameter of ø32mm (1-1/4in) and a headstock stroke of 320mm (12-19/32in), making it suitable for a broad range of machining tasks. Contact our specialist for more technical details.
The SR-32JIII's rigidity is a key factor in its accuracy. The machine's rigid construction minimizes vibrations and deflections during the machining process, ensuring stable production even during extended runs. This results in precise and consistent part production, meeting the required specifications and quality standards. The adoption of dovetail slide ways on multiple axes further enhances this rigidity.
