Metal Inner Spinning Machine Features

Process: square & irregular metal sheets are fixed, and the internal spinning mechanism forms the metal inner hole.
Capacity: Straight Edge, Arc, Small Flanging And Flaring;
Material: aluminum, iron, copper, stainless steel;
Spinning range: Plate Width 200-2200mm; Max Spinning Inner Hole 2000mm; Thickness 1-3mm;
Advantages of internal spinning: lower mold cost and higher efficiency compared to deep drawing; short development cycle.
Deep drawing comparison: metal sheet is flat after metal spinning, and the internal stress deformation caused by deep drawing is small.

CNC Inner Metal Spinning Machine For Industrial Fan Guide Video

CNC intern spinning machines mainly produce:

Industrial radiators, air conditioning fan panels, air conditioning fan guide plates, negative pressure fan outlets, cabinet fan outlet panels, centrifugal fan air inlet cones, impeller guards and other metal accessories;

Main features

The metal plate is rectangular and needs to be formed into a single hole or multiple holes;

Description of metal internal spinning machine

The main features of this machine are similar to hydraulic deep drawing equipment. The working principle is opposite to that of ordinary metal spinning machines. The metal plate is fixed, the spinning roller rotates at high speed, and the spinning is repeated many times, and finally it is formed according to the outline of the drawing!

How to Choose Inner CNC Spinning Machines

Inner CNC metal spinning is mainly designed, developed and produced for sheet metal air guide covers of industrial fans! The machine diameter currently in the testing stage can spin inner holes with a diameter of 2000mm and a wall thickness of 4mm for carbon steel;

Determine the model of the inner metal spinning machine according to the size of the rectangular panel;
Determine the size of the inner hole to be formed, the minimum and maximum inner hole diameters! Ensure that enough
material is fixed on the mold, and the narrowest point cannot be less than 60mm from the inner hole;
In the machine plan confirmation, Altron will assist you in selecting the appropriate machine model, analyze the drawing parts, and determine the final processing plan!
