GMC3030 gantry CNC machining center machine tool

The Gantry Machining Center Refers To The Machining Center Where The Axis Of The Z Axis Of The Main Shaft Is Perpendicular To The Workbench. The Overall Structure Is A Large Machining Center With A Portal Structure Frame Composed Of Double Columns And Top Beams. There Is A Beam In The Middle Of The Double Columns. Especially Suitable For Processing Large Workpieces And Workpieces With Complex Shapes.

The Structural Features Of The Gantry Machining Center Are As Follows:

The Gantry Is Composed Of A Beam And Two Columns. It Can Be Divided Into Three Types: Beam Fixed, Beam Locked By Positioning Block And Segmented Lifting, And Beam Lifted And Lowered Arbitrarily.

The Machining Of Large And Complex Parts Often Requires Many Attachment Heads. The Accessory Head Is Specially Designed According To The Processing Requirements Of The Workpiece, Generally Divided Into a Right-Angle Head, Extended Head, Special

Angle Head And Universal Head Etc.

Numerical Control System. Now There Are Many CNC System Suppliers, And There Are Different Choices Of System Brands And Models According To Different Needs.

1.Base, working platform integrated structure, beam, column integrated structure, overall casting, base multi-point support, the middle of the working platform design has 9 points of support, all-round anti-distortion structure, strong seismic ability, to achieve the best dynamic horizontal accuracy and durability, increase the overall cutting rigidity and cutting stability of the machine tool. Through finite element analysis and optimization design, the structure of the machine tool is optimized. The castings are made of high quality resin sand shape, high strengthcast iron material and cast by mianna casting process. After the secondary aging treatment, the high stability of the machine tool is guaranteed.

2.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.

3.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.

4.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.

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

6.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.

7.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.

8.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

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