CNC Double Column High Precision Vertical Rotary Grinder

JL-100VG

The JL-100VG CNC Vertical Grinding Machine is a high-performance grinder designed specifically for internal grinding. The casting is made of high-grade cast iron, ensuring that the structure remains stable during prolonged use.

This grinder features a digital control system, enabling automated operations through panel graphics. Additionally, it offers optional automatic tool changing system, further enhancing processing efficiency.

Features

  • Drive Mechanism: The X-axis is equipped with precision linear guide rails, allowing the grinding wheel head to achieve precise and accurate motion control during the internal grinding process, ensuring a smooth surface finish. The Z-axis is configured with steel rails. The structural design of steel rails can withstand greater machining forces and pressures, contributing to the overall durability and longevity of the machine tool.
  • Hydrostatic Rotary Table: Equipped with oil temperature and pressure control system, the worktable does not come into contact with bearings, ensuring no noise and avoiding issues related to temperature rise and deformation.
  • Double Column Structure: The machine tool components are crafted from high-grade cast iron, ensuring stability and durability even under prolonged high-load operations.
  • Fully Enclosed Splash Guard: Ensures operator safety and prevents potential hazards such as dust, chips, coolant, etc., generated during the machining process.

Standard Accessories

  • Built-in type wheel spindle.
  • Ring gauge.
  • Wheel dresser.
  • Hydrostatic rotary table.

Optional Accessories

  • Online measuring device.
  • Automatic tool changer.

Application

  • Internal Grinding: Suitable for internal grinding of elongated cylindrical workpieces, including internal holes, internal circles, internal tapers, etc.
