This CZ Sigma Purlin making machine can make C purlin, Z purlin, and Sigma purlin. Now, more and more clients need to produce a Sigma profile using by roll forming machine. To save workshop space and save some cost. We design one machine to produce C channel, Z channel, and Sigma channel.

The main technical specifications of the CZ Sigma Machine

• Forming stand: 28 rolling stands, including 1 rolling stand for flange side 87°-95°adjustment,

Including 12 groups of CZ interchangeable units, turning over 180° can finish changing from C to Z.

• Shaft material: 40Cr, diameter φ95mm/φ80mm
• Processing of shaft: solid shaft, CNC processing, tempered heat treatment HRC 28-32, fine lathe machine processing, electroplate
• Rollers: roller material Cr12
• Processing of rollers: CNC processing, quenched heat treatment HRC 58-60, fine lathe processing
• Machine structure: arch structure, more stable, durable, and accurate
• Transmission: standard by chains
• Rib: linear Rib
• Driven by a servo motor: power 55KW
• Straightening unit: 4 straightening units, make sure the CZ or sigma purlin is straight

• Cutting type: hydraulic, step-less cutting, there is no limit, cutting different sizes, no need to change the blade; only need to adjust the cutting blade
• Blade material: Cr12MoV, quenched, HRC 58-62
• Length measuring: automatic encoder measuring 
• Tolerance of length: 3000mm+- 1.0mm

From this photo, we can see that there are 7 rolling stations that are different from other rolling stations. These 7 rolling stations are used to press the Sigma bottom ribs. When you need to produce the sigma profile, press the up rollers. If you don't need to produce the sigma profile, lift the up rollers.
