The Features of this model
GMC2518 CNC is a fixed beam and fixed column gantry machining center machine tool. It is developed based on the most popular, advanced and flexible machine tool design concepts in the world. It is suitable for aerospace, shipbuilding, power generation, industry, heavy machinery, locomotives, machine tools, and textile machinery. Printing machinery, automotive covering molds and other industries of various large-scale workpiece machining equipment.

Advantages of gantry machining centerThe machine tool's high-strength, high-rigidity design and large-flow chip removal channel structure have the characteristics of high precision, high efficiency, flexibility, and environmental protection. Its performance indicators and accuracy indicators comply with relevant national standards.

GMC2518 adopts the gantry structure of moving table. The bed is fixed, the worktable moves in the X direction on the bed; the ram moves in the Z direction on the sliding seat; the sliding seat and the ram move in the Y direction on the gantry beam; the X and Y axes adopt heavy-duty linear rails, Z The shaft is a plastic hard rail. The main shaft assembly is placed at the lower end of the ram; the whole machine has a reasonable layout, beautiful appearance and convenient operation

1. Three axis guide rail

X / Y / Z axis standard with Taiwan HIWIN / PMI rail, small beating, low friction and high running speed. Strong rigidity, large bearing capacity, and long service life. With Taiwan Okada 24T disc manipulator knife warehouse, improve the processing efficiency. Standard 8000 rpm high rigidity high precision BT40 spindle, direct connection drive, high transmission efficiency. The Z-axis is equipped with a double nitrogen balance cylinder to reduce the motor load and improve the response speed.

2. Three-axis bearing

The three-axis bearings use German FAG / Japanese NSK brand, the main electrical components use French Schneider / Japanese Fuji and other brands, the pneumatic system adopts Japanese SMC / CKD brand, the reducer adopts imported high precision and low backgap, stable processing accuracy. The big brand configuration of real material, to ensure that its easy to use, quality assurance, more durable.

3. External protective sheet metal

High semi-closed around the full protection, waterproof effect is good. Double open open door, the door size is large, convenient loading and unloading. Rotary boom operation box, convenient operation and debugging. On both sides of the workbench double screw row + front side chain row, convenient exhaust.

4. Pneumatic system

It is mainly used in clip knife; spindle center blow; spindle front seal blow.

5. Lubrication system

The three axes are lubrby grease. The ball screw pair adopts automatic dilute oil lubrication mode. Three coordinate guide track, there is automatic control of the lubrication point, lubricating oil through the shunt lubrication guide track, the action is automatically controlled by the numerical control system.

6. Electric cabinet

The heat exchanger of electric control box is installed in sealed type, avoiding convection from internal and external air; blocking moisture, oil, gas and dust into the electric control box; simplified light space and simple maintenance.

Electric control box air conditioning (optional): the special air conditioning machine (air conditioning) can be selected according to the external environmental conditions; the temperature control accuracy of electronic temperature control is ± 1℃, which can keep the constant temperature in it, control the heat source and have dehumidification function, and improve the life of electronic components.

7. Spindle oil cooler

This machine tool can be equipped with thermostatic control oil cooling machine, can prevent the mechanical spindle due to temperature rise and affect the working accuracy, improve the mechanical processing accuracy and efficiency, prevent the working machine spindle center deviation or hot deformation, prolong the mechanical life, stabilize the oil pressure, prevent oil shock, simple operation, low noise operation

8. System

Siemens / Fanuc / Mitsubishi system, with very high reliability. Good stability, low failure rate, strong performance.
