Description

The MY3270 is a heavy-duty hydraulic surface grinder, engineered for high-precision flat grinding, surface finishing, and precision sizing of large and medium-sized metal workpieces. It features a fully automatic hydraulic table traverse system combined with manual fine adjustment, making it ideal for mold manufacturing, tool and die shops, heavy machinery component processing, and general precision machining industries, perfect for both small-batch prototyping and mass production.

Built with a reinforced, stress-relieved cast iron frame and precision linear guideways, it delivers exceptional rigidity and vibration-free operation even under heavy cutting loads. The machine is equipped with a high-torque, precision-balanced spindle assembly, a robust hydraulic drive system, and an ergonomic control panel. Integrated with a large-capacity coolant system, automatic centralized lubrication, and magnetic chuck compatibility, it ensures consistent, high-quality surface finishes with minimal operator intervention. Backed by CE/ISO certification, a 12-month global warranty, and full customization for voltage and configuration, it meets the stringent standards of global metalworking industries.
