Types of Grinding

  • Surface: Precision grinding is performed on flat surfaces to ensure the smoothness and parallelism of the workpiece surfaces meet precise requirements.
  • Creep Feed Grinding: The deep plunge grinding machinery we offer is suitable for achieving top shape precision and surface smoothness through deep grinding of workpieces. This is particularly applicable in the manufacturing of molds and precision components.
  • Profile (Forming) Grinding: Molding grinding machinery is employed in the manufacturing of workpieces with unique shapes, achieving highly consistent shapes through molds or duplicators. This is suitable for producing various non-standard-shaped components.
  • Hard Materials: Designed specifically for grinding hard materials such as hard metal alloys and ceramics, ensuring the maintenance of high hardness and surface quality throughout the grinding process.
  • Internal / External: It can process both the inner and outer diameters of workpieces, achieving comprehensive machining, particularly suitable for applications requiring highly consistent surfaces on both the inner and outer diameters.
  • Mirror: Utilized in the manufacturing of workpieces with highly reflective optical properties, such as lenses and optical components, ensuring that surface flatness and quality meet superior standards.
  • Silicon Wafers / Compound Semiconductors: Applicable in the semiconductor manufacturing field, achieving high-precision grinding of silicon wafers and compound semiconductor materials, ensuring that the processes comply with industry standards.
