Setup
Proper installation is crucial for the safe and effective operation of your surface grinder. Follow these steps carefully.
Uncrating
Carefully remove the machine from its shipping crate. Inspect for any visible damage that may have occurred during transit. Retain all packing materials until the machine is fully installed and tested.
Placement
Position the grinder on a solid, level foundation capable of supporting its weight. Ensure adequate space around the machine for operation, maintenance, and material handling. Maintain proper ventilation.
Leveling
Use a precision level to ensure the machine is perfectly level in both longitudinal and transverse directions. Adjust the leveling feet as necessary to achieve stability and prevent vibration during operation.
Electrical Connections
Connect the machine to a power supply that matches the voltage and phase requirements specified on the machine's data plate. Ensure all electrical connections are made by a qualified electrician and comply with local electrical codes. Verify proper grounding.
Operating Instructions
Familiarize yourself with the controls and functions of the DoALL G-10 and G-14 Surface Grinders before beginning any operation.
How to "Grind In" your New Chuck
To ensure optimal accuracy and parallelism, a new magnetic chuck must be "ground in" after installation. This process involves lightly grinding the chuck's surface with a grinding wheel to achieve a perfectly flat and parallel workholding surface. Consult the detailed steps in the original manual for specific procedures and recommended grinding parameters.
Mounting the Wheel
Select the appropriate grinding wheel for your application. Ensure the wheel's bore matches the spindle diameter. Mount the wheel securely onto the spindle flange, using blotters and tightening the retaining nut to the specified torque. Always perform a ring test on new wheels before mounting to check for cracks. Balance the grinding wheel after mounting to prevent vibration and ensure a smooth finish.
Maintenance
Regular maintenance is essential for the longevity and reliable operation of your DoALL surface grinder. Follow the lubrication schedule and procedures outlined below.
Spindle Lubrication
The spindle bearings require specific lubrication to maintain high precision and prevent premature wear. Refer to the lubrication chart for the recommended lubricant type and frequency of application. Over-lubrication or under-lubrication can both lead to issues.
Hydraulic Reservoir
Regularly check the hydraulic fluid level in the reservoir. Maintain the fluid level between the indicated marks. Periodically inspect the fluid for contamination and change it according to the manufacturer's recommendations to ensure smooth hydraulic system operation.
Pump Motor
Inspect the pump motor for unusual noises or excessive heat. Ensure the motor's cooling fins are free from dust and debris. Lubricate motor bearings if specified by the motor manufacturer's guidelines.
Saddle and Table Ways
Keep the saddle and table ways clean and free of grinding swarf. Apply a thin film of way lubricant regularly to ensure smooth movement and prevent wear. Check for any signs of scoring or damage.
Column & Elevating Screws
Lubricate the column and elevating screws with the recommended grease or oil to ensure easy and precise vertical adjustments. Keep these components clean to prevent abrasive wear.
Troubleshooting
This section provides general guidance for common operational issues. For detailed troubleshooting steps and solutions, refer to the comprehensive troubleshooting guide within the full manual.
- Machine not starting: Check power supply, emergency stop button, and circuit breakers.
- Poor surface finish: Inspect grinding wheel for wear or imbalance, check wheel dressing, verify coolant flow, and ensure workpiece is securely clamped.
- Excessive vibration: Check wheel balance, spindle bearings, machine leveling, and motor mounts.
- Hydraulic system issues: Check fluid level, filter condition, and pump operation.
If problems persist, contact qualified service personnel.
