      Shuokai large gantry machining centerLM-1402/LM-1502/LM-1503/LM-2202B/LM-2203B
       
      Shuokai large-scale gantry machining center adopts casting base, super-large column and crossbeam box structure. The machine tool has strong rigidity and high stability. The crossbeam adopts oblique back design. The widened slideway has a wide force and the center of gravity of the head is close to the average Beam center to achieve better motion accuracy and heavy chipping ability. Design the center symmetrical spindle system to ensure the configuration of the spindle, spindle motor, ball screw and variable weight hydraulic cylinder position to avoid heating and displacement, resulting in imbalance and affecting processing accuracy. The Z-axis variable weight oil cylinder adopts suspended support, close to the position of the center of gravity of the movement, and is symmetrical with the configuration of the main shaft, driving screw and main shaft motor center, in order to eliminate the unbalanced force generation and ensure the precision of micro-feeding processing. Y-axis square rail slide, full-stroke mobile support, stable motion bearing up to 25000kgf.

      Performance characteristics：

      1. Machine tool precision and stability:
      1、Ensure working accuracy, positioning accuracy and repeat accuracy during high-speed operation±0.005。
      2、Shuokai large-scale gantry machining center, high-rigidity integrated base and wide column base are made of Mina cast iron. Its ultrafine particle structure has high physical properties and will not be distorted in harsh environments.
      3、The main shaft structure adopts high-quality alloy steel parts, with precise structure and stable operation.
      4、The casting is calculated and analyzed by the finite element analysis method. The structural strength and the combination of reinforcing ribs increase the rigidity of the machine.
      5、Three-axis adopts C3 large-diameter screw, pre-tensioned design at both ends, excellent rigidity, X and Y axes adopt heavy-load roller linear guide, Z-axis slide rail / roller linear rail are optional, can support heavy load, fast Movement, accurate positioning.
      6、The cast iron base has a wide and solid structure, the saddle is widened and lengthened, and the full support design has excellent heavy load capacity and machine tool stability.
      7、The main shaft cavity is reinforced with ribs, and the main shaft is firmly supported to ensure the accuracy of processed products during high-speed operation.
      8、Z axis adopts energy storage nitrogen balance design, excellent motion balance, precise and reliable processed products.
       

      2. Shuokai large-scale gantry machining center adopts imported high-precision and high-performance spindle:
      1、Fast response, high strength and high processing efficiency.
      2、The high-strength four-lobe claw broach has a large contact surface, a strong gripping force, and a small loss of the tool head.
      3、Shuokai gantry machining center adopts high horsepower spindle motor, which is suitable for high-speed heavy chip processing. It adopts mechanical pressure knife release device to complete loading and unloading while Z axis moves, which improves tool change efficiency.
      4、The spindle is directly driven by the motor and directly transmits torque to obtain a higher drilling and tapping effect.
      5、High-speed spindle operation with spindle oil temperature control system, automatic temperature difference detection control, to ensure that the spindle runs at a constant temperature, improve the spindle running accuracy and life.
       

      3. Application field of Shuokai large gantry machining center:
      It is suitable for processing large-scale automobiles, home appliance molds, military products, mold frame processing and other related products.
