Matters Needing Attention in the Installation and Daily Maintenance of CNC Gantry Type Machining Centers

CNC Gantry Type Machining Center is a high-precision, efficient automated device. It has specific requirements for early installation and later maintenance. If your Gantry Type Machining Center has errors or low processing efficiency, we will suggest you check it.

CNC Gantry Type Machining Center Installation Requirements

The higher the precision of a CNC Gantry Type Machining Center, the stricter the requirements for poor installation environment, temperature, humidity, and vibration. Let us briefly discuss the installation foundation requirements for a CNC Gantry Type Machining Center.

The installation of the gantry foundation must be firm, and the foundation should be made according to specific foundation drawings created by the manufacturer. For tight concrete floors, if thick enough, the anchor bolts can be directly installed according to the drawings. For loose ground, it must be re-excavated and constructed according to the foundation drawings, and enough thick concrete should be poured to prevent the Gantry Type Machining Center from sinking at a later stage. After sinking, the bed will deform, so it will not have precision. The foundation size must not be smaller than the shape size of the support area of the Gantry Type Machining Center. The construction thickness of the foundation concrete must meet the standard.

Gantry Type Machining Center processes large workpieces, causing vibration easily. The heavier the Gantry Type Machining Center, the thicker the foundation. The low-pressure strength of the concrete is 1800 N per square meter, and the tensile strength is 180 N per square meter. The load-bearing strength of the ground should be more than 5 tons per square meter. There should be no cracks in the concrete foundation, and the foundation workshop should add shockproof materials.

The tool magazine is a high-precision machine tool device. In daily use, how to maintain the Gantry Type Machining Center's precision and extend its service life?

Gantry Type Machining Center Precision Maintenance Checklist

• The startup preheating time is about 10 minutes. If the machine has been idle for a long time, the preheating time should be appropriately extended.

• Check if the oil circuit is smooth.

• Before shutting down, place the workbench and saddle in the center position of the machine (move the three-axis travel to the center of each axis travel).

• Daily cleaning of the Gantry Type Machining Center.

Gantry Type Machining Center Daily Maintenance

• Check the liquid level height of the Gantry Type Machining Center lubricating oil. It is recommended to use T68# guide rail lubricating oil.

• Add coolant to the Gantry Type Machining Center's coolant tank in time.

• Check the oil level height of the Gantry Type Machining Center pneumatic three-piece, approximately 2/3 of the entire oil pipe height.

• Drain the water vapor in the pneumatic three-piece oil filter tank every day through the drain switch.

• Check the Gantry Type Machining Center's air pressure, relax the adjustment knob and adjust the pressure according to the principle of right turn to increase and left turn to decrease. It is generally set to 5～7KG/㎝². The pressure switch is generally set to 5KG/㎝². When it is lower than 5KG/㎝², the system will alarm. The alarm message disappears when the pressure increases.

• Check if the air blow in the Gantry Type Machining Center spindle taper hole is normal. Wipe the spindle taper hole with a clean cloth and spray it with light oil.

• Timely clean the Gantry Type Machining Center's tool arm, tools, and tool claws. Clean the Gantry Type Machining Center's exposed limit switches and collision blocks.

• Remove chips and oil stains from the Gantry Type Machining Center's workbench, CNC machining center, and three-axis flexible shields.

• Check if all the signal lights and abnormal warning lights of the Gantry Type Machining Center are normal. Check if the pipeline of the Gantry Type Machining Center oil pressure unit is leaking.

• After completing the daily processing tasks, cleaning should be performed to ensure that the surrounding areas of the Gantry Type Machining Center are organized.

• When the Gantry Type Machining Center is not used for a long time, it should be cleaned, and the machine tool guide rails should be coated with lubricating oil to prevent rust.
