(Saddle Series) Fully Auto High Precision Surface Grinding Machine

JL-52ATDII / JL-2550ATDII / JL-63ATDII / JL-4080ATDII

Fully Auto High Precision Surface Grinding Machine (ATD Series) is a fully automatic precision surface grinder equipped with an advanced microcomputer controller, enabling efficient achievement of fine grinding surface results while improving production efficiency.

The vertical axis elevation is controlled by a stepper motor with adjustable speed, and operates in conjunction with an electronic handwheel for precise control, achieving a minimum feed rate of 0.001mm.

Features

  • Microcomputer Control: The vertical axis is controlled by a stepper motor, allowing adjustable speed. The total automatic feed can be flexibly set to either 450mm or 600mm. Combined with electronic handwheel operation, precise control of the minimum feed rate down to 0.001mm is ensured, ensuring high-precision machining results.
  • Multiple Standard Worktable Sizes: Provide 200 x 500 (mm)、250 x 500 (mm)、300 x 600 (mm)、400 x 800 (mm) Multiple worktables are available to meet common machining needs in the market.
  • Spindle: Utilizing V-3 grade motor direct drive. With minimal transmission error and excellent lubrication, it can effectively extend the spindle's lifespan. The vertical feed adjustment of the grinding wheel head can reach 0.005mm.
  • Rigid Structure: The machine structure is made of advanced Meehanite cast iron, ensuring optimal machine rigidity and vibration resistance.
