Features

The flat surface grinding machine bed and worktable are constructed from high-quality, wear-resistant cast iron and feature a monolithic casting design. Utilizing specialized 3D analysis software, the components underwent rigorous stress analysis to ensure optimal dimensions and a rational structural layout, thereby guaranteeing a balanced distribution of forces. Furthermore, the castings were subjected to a dual-stage vibration aging process to minimize residual stress following machining.

The structure of the flat surface grinding machine grinding head spindle is a critical component of the grinding machine, directly influencing grinding precision, surface roughness, waviness, and grinding efficiency. The grinding head structure on this machine tool utilizes a hydrodynamic-hydrostatic bearing design.

a. The horizontal grinding head, featuring a hydrodynamic-hydrostatic bearing structure, offers numerous advantages, including high rotational precision, high load-bearing capacity, excellent vibration resistance, and a long service life.

b. The grinding head is equipped with an independent oil supply system. This system incorporates an oil cooling device to regulate the temperature rise of the spindle's lubricating oil, thereby ensuring the rotational precision of the spindle. Furthermore, the system employs multiple protective measures-including a two-stage precision oil filtration system, low oil pressure protection, and an accumulator-to safeguard the spindle.

The flat surface grinding machine is driven by an independent hydraulic station, the system features stepless speed regulation, ensuring smooth operation and convenient handling. The hydraulic station is equipped with an air-cooling device, resulting in minimal temperature rise within the system oil.
