Main configration

Frame		O-type closed integral welding press frame special for servo punch press.Holistic welding structure, stress relief from tempering treat- ment.The strong rigidity and high tonnage ensure the stable accuracy for long time, extend the service life of the machine and tools, and improve the positioning precision, reliability and durability.
Drive Mode		Mechanical drive mode, through the main motor to drive the flywheel rotation, the use of flywheel inertia stamping, stamping control by the clutch, simple structure, low product price, stable performance, simple and convenient maintenance.
Full Auto Indexed Station		Unique worm gear structure to ensure the ac- curacy of positive and negative bidirectional transmission. Single import synchronous belt drive to ensure synchronization between up and down.
Worktable		The worktable surface with hard brush and steel ball, to lower down the noise while working and protect the surface of the sheet. Seamless worktable design to avoid collision during sheet metal movement. Folding table design, side auxiliary platform automatic fold- ing control, easy to change tooling. Aluminum edging design, side aluminum edging, protect the worktable surface from wear. Side loading auxiliary roller, easy to loading the plate.
Floatable Pneumatic Clamps		The pneumatic floatable clamps reduce the deformation of the plate. The self-protection function makes no dead area for punching on sheet. The clamp automatically floats when clamping the plate, convenient for the plate clamp. Automatic unloading when the clamp returns.
Turret and Tooling		Precision wear-resistant guide holder inlaid on turret, large machining center in pairs pro- cessed International standard Japan AMADA long guide tool, Reasonable.
Feeding System		High-precision Feeding: X, Y-axis guides and lead screws are integrated, ensuring precise material handling. Pneumatic clamps enhance stability.
Lubrication System		Multi-point automatic lubrication ensures sufficient lubrication, reducing wear.
