Gantry-type Machining Center vs Traditional Structure

Traditional structure	Yangsen new
Traditional structure: double track T-type ram. The traditional structure is connected by a belt, which has high noise and poor dynamic balance effect. It is easy to produce vibration tool marks during processing and cannot be processed at high speed.	Yangsen new: four-Rail square ram. The built-in direct connection design reduces the power transmission consumption from the spindle motor to the spindle.
Traditional structure double track T-type ram The traditional T-shaped ram adopts the design of double track (6 sliders), which has poor rigidity.	Yangsen new four-Rail square ram Yangsen adopts four-line rail (10 sliders) square ram structure design, which has stronger rigidity
Common square ram: direct coupling spindle Common square rams are driven by long couplings, and the length of the coupling is too long to easily cause motion: 1. Poor dynamic balance effect 2. Low transmission rate 3. There is a problem of torque loss	Yangsen new: built-in motor spindle Yangsen’s new model adopts built-in direct installation, cancels the long coupling and reduces the use of built-in direct installation: 1. Reduce the problem of torque loss in long couplings 2. Improve machining accuracy and cutting rigidity 3. Good dynamic balance for finishing and high surface finish
Traditional:Structural Beams. The traditional structure only has no reinforcement ribs inside the beam box structure.	Yangsen new:Cross rib thickened beam. Yangsen’s new beam has a large span and adopts a cross rib structure with strong deformation resistance
Traditional:Structural Columns.	Yangsen new:Sun rib Columns 1. The one-piece cast column structure, combined with the thick column section size, effectively connects the rigidity transmission between the beam and the base, and greatly improves the cutting rigidity of the YZ axis. 2. The sun-shaped rib design inside the column provides high stability and high rigidity
1. Split bearing motor base, the coaxiality of the bearing and motor installation holes is difficult to control; the screw and the motor are connected by a belt, there is a gap, and the transmission rigidity is poor. 2. The auxiliary support structure of the fixed-point lead screw, the spring support force is unstable, and the gravity deformation of the follow-up support lead screw is large.	1. Yangsen’s One-piece bearing motor base, strong rigidity, high coaxiality of the bearing and motor installation holes; the connection between the screw and the motor is connected by a planetary reducer, no gap, and good transmission rigidity 2. The follow-up screw auxiliary support structure reduces the influence of the position accuracy caused by the gravity droop of the long-stroke screw

Gantry Machining Center Structural Features:

1. Workbench:

The table of the gantry machining center is basically rectangular. The large and heavy castings such as the table, bed, column, beam, and ram are made of cast iron or welded parts. The inner cavity of the casting is a honeycomb composite arrangement structure with advanced design, all of which have been treated by aging and secondary tempering to eliminate residual internal stress and stabilize the material, to ensure the stability of workpiece machining accuracy and machine tool life.

2. Spindles:

Using BBT50-D200 high rigidity spindle, 6 imported large steel ball bearings, super cutting ability.

3. Gantry--column:

The gantry consists of a beam and two columns. It can be divided into three types: beam fixed, beam locked by positioning block segmented lifting, and beam free lifting.

4. Ram:

The ram can be divided into two types: open type and closed type. The ram of the open structure is clamped on the headstock by the pressure plate, and the cross-sectional area of ​​the ram is large; the ram of the closed structure is clamped in the headstock, and the cross-sectional area of ​​the ram is small.

5. Automatic Tool Changers (ATC) System:

There are three basic types of tool magazines: turret type, drum type, and chain length type.

6. Accessory Header Charger System:

The machining of large, heavy, and complex parts often requires many attachment heads. The attachment head is specially designed according to the processing requirements of the workpiece and is generally divided into a right-angle head, extension head, special angle head, and universal head.

7 Gantry Machining Center (Computerized Numerical Control) CNC System:

There are many CNC system suppliers, and there are different choices of system brands and models according to different needs.

8. Gantry Machining Center Processing Accuracy:

The accuracy of the machine tool refers to the original accuracy of the machine tool under the condition of no external load. Accuracy is usually represented by its opposite - the deviation from the ideal state (abbreviated as error), and the smaller the error, the higher the accuracy.
