Description

  • The EGA Series is designed to achieve high precision, efficiency, and ease of operation.
  • They find suitability across various industries, including automotive, medical instruments, tooling, job shops, and mold industries.
  • Work Head: The work spindle, equipped with NN bearings, provides heavy-duty load capacity, optimal rotation accuracy, and high rigidity.
  • The servo motor drive maintains consistent speed and torque during grinding operations.
  • A positive purge system keeps grinding swarf and coolant out of the work head, ensuring a long lifespan.
  • Rigid Machine Base: The machine base is designed to ensure rigidity, fully supporting the table on both ends.
  • It consists of a heavily ribbed box-type base made of Meehanite casting, offering excellent rigidity and maintaining machine stability.
  • Wheel Head Spindle Bearing Options: Standard The contact bearing type spindle is easy to maintain, environmentally friendly, and minimizes thermal growth issues.
  • Tailstock: Equipped with a coolant nozzle on the top for cooling the center tip, the tailstock features an air floating device that facilitates smoother movement and table protection.
  • Optional tailstock quill travel of 75 mm aids in easy workpiece loading/unloading.
  • The oil-bathed quill enables smooth movement, and the optional taper adjustment feature makes it easy to correct taper errors.
  • X-Axis Guideways: The hand-scraped Double V guideways offer maximum support to the wheel head, resulting in greater stability and grinding capacity.
  • This design ensures superior accuracy and extends the machine's lifespan.
