The MM high-speed compact through-hole rotary hydraulic cylinder is a patented product from Auto-Strong, with global patent coverage. Its lightweight and compact design aligns with international green and environmental trends. The special oil circuit design allows for flexible installation angles, making it suitable for both horizontal lathe main spindles and inverted lathes. The patented safety check valve design, combined with global product liability insurance, maximizes safety.The MM1552B has also won the Taiwan Golden Jade Award and the Innovation Achievement Excellence Award, making it a product exclusive to Auto-Strong.

Leading the industry, we have developed and launched the "extra-large bore design paired with A2-6 spindle" to meet international market trends, enhance machine cost-effectiveness, and satisfy specific customer needs.The CR65A6 collet chuck is typically used in NC/CNC lathes, automatic bar-feeding lathes, sliding head lathes, and dedicated machining centers. Its front-loading clamping operation allows customers to quickly detach the stop cover, significantly improving efficiency and convenience. This model features a large bore design that is interchangeable with the A2-6 spindle and the Auto-Strong NB-208 large bore hydraulic chuck, providing customers with more options. It is known for its high precision, high speed, high rigidity, and high durability.

The newly developed hollow rotary hydraulic cylinder is "lighter, thinner, and easier to install." With its lightweight, compact design and front-rear lock installation feature, it not only saves internal space in the machine but also makes installation more convenient. The MB2091 is 30% shorter in length compared to the previous M-series product. In addition to providing more stability during high-speed rotation, its weight has been reduced by over 10 kilograms, significantly lowering the spindle load and saving energy, achieving environmentally friendly and energy-efficient results. The MB2091 slim hollow rotary hydraulic cylinder is equipped with a new patented design, featuring a patented check valve safety mechanism that ensures pressure retention in the event of a power outage. Combined with global product liability insurance, this design maximizes safety protection, fulfilling Di Chun Iron Works’ commitment to its customers. The MB2091 has also been awarded the prestigious "Gold Label" in the 2024 TMBA Machine Tool Industry Energy Efficiency Certification. Currently, Di Chun Iron Works is the only company to have this product with such recognition.
