          G-230MY							
          

						
							
          

								
          Description: 
          

								
          

								The G-250M and G-220M lathes are particularly suitable for turning,milling,drilling and other one-time molding processes in rough and fine procedures of medium-large shafts and disks parts.The whole equipment adopts entire enclosure protection and features stable and solid,with an extensive use in the production of parts for various industrial products.In addition,it is available to be configured with high-speed robots on demands,realizing unmanned flexible production.
								
          
								
          

							
          
							
          
							
							
          
							
								
          Features:
          
							
								
          
							
								
          1、Y-axis:It realizes a compound function of turning and milling using an interpolated Y-axis structure,or turret with Y-axis structure.(model shall be marked with “Y”）
          2、spindle:The spindle is structured with a high-power,large-torque,and high-precision sleeve,characterized by increased reduction ratio and good low-speed performance,and configured with a high-precision internal magnetic ring encoder,thereby being suitable for C-axis cutting. 
          3、Turret:It is configured with the servo motor indexing, crankset positioning and hydraulic clamping mechanisms.It achieves milling-turning machining by a variety of fixed tool seats,0°，90°，and universal milling heads.
          4、X/Z-axis:It is driven by a high-grade imported precision ball screw with the roller guide widened and span increased,thereby with standing heavy cutting.
          5、Tailstock:Automatic programmable tailstock for easy operation and application
