ESTUN E21S NC Hydraulic Shearing Machine
【Series】:Hydraulic Shearing Machine

1. Main Features

  1. Streamlined design originated from EU,the kind ofmachine tool consists of rack, cutter holder, oil cylinder, hydraulic controller, backgauge and other components. Finite-element analysis of main parts, welding parts uses tempering, vibration and other processing methods to eliminate stress ensuring the structural strength and rigidity of the rack and components;
  2. Cutter holder use three-point support rolling guide rail, reducingthefriction to the greatest extent and realizing seamless rolling during cutter holder moving.
  3. Leftmost front holder configured with verticalityregulatorand front positioning device, easy operation and high efficiency;
  4. Simple and effective adjusting mechanismis used torearrange blade clearance via CNC system, improving the cutting quality.
  5. Fine ball screw and bar structure, good-performance frequency converter is used to positioningX axis to ensureaccuracy, unique designed timing transmission-mechanism, stable and reliable.
  6. Light and shadow line is conductive to manual scribing for cutting; stable and reliable hydraulic transmission, integrated hydraulic system is ableto significantly alleviate problems causing by hydraulic fluid leakage.
  7. Made by high-quality alloy tool steel capable enough to against impact load and highwearresistance when cutting
  8. With reference to ergonomic design, easy CNC system surface, improving the operation precision and comfort; rolling ball worktable to reduce friction and prevent work piece from scratching; novel and practical safety guard device,line withsafety specification, protect the personal safety; delicate design, petty work piece can be done easily by hand.
