LESTHER J-NCL Single Head Cutting Machine

The LESTHER J-NCL is a horizontal automatic high-production cutting machine for aluminium with a special design which helps avoid return-cutting, while ensuring fine surface of cut and cutting accuracy.

Features

  • Automation feed, positioning. oil splashing and sawing.
  • Feed stroke 1,250mm/2,500mm/6,000mm. (Repeat cycle feed stroke no limit for length)
  • Horizontal cutting and saw move on linear guide way, that assure accurate and large cutting.
  • Employ touch sensing screen for maximun operation convenience. The controller. Features self-diagnostic function which is displayed on the screen for convenient troubleshooting.
  • Feed driven by hydraulic system, providing maximum stability of cutting.
  • Two sets each of vertical clamps and horizontal clamps provided on the feeding system permits cutting of irregular work piece.
  • 100 sets of size memory capacity. Each set allows for setting 12 sizes.
  • The computer automatically records required time and quantity for each machining, providing convenient calculation of machining cost.
  • During operation, the machine provides detection for lack of material. Available to set remain material.
  • Feed models :
    • Stepping feed
    • Repeat cycle feed
    • Manual feed

Sawblade Feed Way Diagram

Specially designed cutting way:After the saw blade moves forward for cutting, table moves to right and left for retracting 2 mm.Then the saw blade return to its home position. This special design may avoid return-cutting, while ensuring fine surface of cut and cutting accuracy.

  1. Clamping material
  2. Cutting material by straight line
  3. After cutting
  4. The right moves backward by 2mm
  5. Sawblade returns to original position
  6. Worktable returns to original position

Feed Table's Clamps

The clamps on the feed table are suited for cutting irregular stock without need of additional fixtures to fix the work piece.

Auxiliary Support

Auxiliary support prevents work piece deflection.

Transmission Device

Employs precision ground rack with accuracy up to 0.02mm ( suitable for 3 and 6 meter feed travel )

Vacuum Oil Mist Unit

The vacuum oil mist unit employs vacuum generation principle to transform cutting fluid into oil mist for spraying. It provides lubrication and cooling functions, ensuring no dust deposit and saw blade, high cutting accuracy and long service life of saw blad.
