Core Product Advantages
1.Durable Structure
The 12 series manual centerless grinding machine body is made of high-quality castings, optimized through natural aging and heat treatment processes, resulting in minimal deformation and a long service life. The grinding wheel (GW) and guide wheel (RW) adopt a cantilever design, facilitating wheel replacement. The grinding wheel is fixed to the machine bed, ensuring more stable and reliable operation.
2.High-Precision Control
The cross roller guide rail, combined with a servo motor and ball screw, achieves precise feed of the guide wheel, with a minimum feed amount of 0.001mm driven by the servo motor. The grinding wheel dresser is driven by a servo motor and ball screw for feed and reciprocating. The guide wheel dresser supports stepless speed regulation, offering flexible operation and outstanding precision.
Application Scenario
The 12 series manual centerless grinding machine is compatible with both hydrodynamic and hydrostatic structures, and is widely used in precision manufacturing fields such as automotive and motorcycle parts, electrical appliances, molds, cutting tools, tungsten steel, ceramics and glass, medical devices, and aerospace, meeting the needs of high-precision batch processing of small and medium-sized workpieces.
