Machine Features

AUtomatÍc PYecÍSÍon SUt face GrÍndÍng MachÍne - The highly advanced AD111 series of automatic precision surface grinding machines are a result of the ongoing and extensive research and development program
at CHEVALIER. in addtion to improved accuracy, quality, and machine life, the overall design of the machine incorporates ergonomics; all operating handwheels, levers ,stroke setting devices and the pendant control panel are
arranged to allow ease of operation, which increases working efficiency.

Driving Force Test - After the guide ways are assembled, the resistance to movement on each axis is inspected
to ensure that the proper preload is set and that friction is minimized, resulting in maximum life of the guide ways.

Spindle System

Spindle Bearings: The spindle is supported by four pieces of Class 7 P4 super precision angular contact ball bearings, accurately measured, selected, preloaded, and assembled in a temperature-controlled clean room.Lubrication: The spindle is permanently lubricated and requires no maintenance.Balance: Spindle motor, spindle shaft, and couplings are precisely balanced to ensure accuracy and superb surface finish.

Elevating Guideway System

Construction: The wheelhead and column system is composed of hardened and ground inserted steel guideways and precision roller bearings.Preloading: The wheelhead and column guideways are preloaded to provide zero clearance for precise straight-line movement.Low Friction: The low friction wheelhead guideway system enables accurate feeds even at minimal increments.

Machine Construction

Table Guideway System: Composed of hardened and ground steel guideways with precision needle roller bearings to ensure longevity, low friction, and precise linear movement without deviation, even during rapid traverse movement.Saddle Guideway System: The saddle guideway system includes specially designed preloaded needle roller bearings and hardened and ground slide rails. Loading bearings support vertical load, and preloaded leading bearings assure accuracy of the saddle's cross movement, providing longevity and low friction, stick-slip free accurate movement.

Control Features

Adjustable Control Station: Can be adjusted to a comfortable position for the operator, with all switches, buttons, LEDs, indicating lamps, and displays ergonomically positioned for user-friendly operation.Control Interface:High reliability NC control platform.8" TFT high-resolution 65,536 pixel color touch panel control interface.Powerful graphic conversational function with surface/plunge standard built-in grinding program.Clear operation panel.Machine abnormal alarm message display and alarm history record.Y-axis home positioning function.Multi-language support.Display of mechanical and relative coordinates.Digital I/O check mode for efficient service.User-friendly operation for grinding, wheel dressing, and automatic compensation without needing CNC programming.
