(Column Series) Fully Auto Precision Surface Grinding Machine

JL-5010ATD ~ JL-7020ATD

(Column Series) Fully Auto Precision Surface Grinding Machine is Driven by a hydraulic system, this drive mode is less prone to vibration, effectively preventing the generation of threads on the workpiece surface, thereby enhancing processing quality.

The Z-axis feed adopts dual V-guideways and motor drive, equipped with advanced automatic tool approach function, providing the machine with stable and efficient motion performance. Models JL-5010 and above can be controlled through electronic handwheels, allowing operators to easily manage the process of automatic tool approach.

The main structure is made of high-quality cast iron, ensuring the machine's robust rigidity, resistance to deformation, and maintaining the stability of machining accuracy.

To better meet the practical needs of customers, Joen Lih has specifically designed multiple standard worktable sizes based on common workpiece dimensions. This allows customers to choose the most suitable grinding machine according to their actual machining cases.

Features

● Column Type: Utilizing a high-grade cast iron construction for the column, providing excellent robustness and durability.
● Multiple Standard Worktable Sizes:
Various worktable sizes are offered, including
500mm x (1000、1500、2000)mm
600mm x (1000、1500、2000)mm
700mm x (1000、1500、2000)mm
It can meet common processing requirements in the market, and the cross movement adjustment range for the worktable can reach 0.02mm.
● Auto Down Feed: Configured with a servo motor electronic handwheel control system, this setup ensures high-precision machining results with a minimum feed rate of 0.0001mm.
● Spindle: The precision cartridge spindle is incorporated with P4 super precision angular contact ball bearings in a temperature controlled room to ensure the highest accuracy and superior grinding finish.
● Rigid Structure: The machine structure is made of advanced Meehanite cast iron, ensuring optimal machine rigidity and vibration resistance.
