High-Quality CNC Bed Leveling Manufacturer & Suppliers

A basic sheet flattener typically utilizes 5 to 7 rolls without intermediate backups. It only removes obvious gross curl (coil set) by applying minimal surface bending, leaving high differential residual stress inside the core of the sheet. In contrast, a CNC roller leveling machine employs 13 to 23 smaller-diameter, closely spaced rolls supported by multi-segment adjustable back-up roller banks. The CNC controller precisely bends the sheet past its elastic limit (70-85% plastic deformation) through alternating decaying curvatures. This eliminates edge wave, center buckle, camber, and crossbow while equalizing internal stress throughout the sheet thickness, ensuring the metal stays flat during subsequent laser cutting, stamping, or bending.

We manufacture complete automated coil processing systems: high-precision slitting lines (rotary shear lines), stop-and-go cut to length lines, continuous flying shear and moving shear production lines, CNC bed leveling and straightening machines, and continuous hot-dip galvanizing production lines. Equipment can be supplied as a complete turnkey turnkey system or as standalone high-precision leveling modules to retrofit and upgrade existing customer lines.

Our lines are engineered to process hot-rolled carbon steel, cold-rolled sheet, galvanized coil, high-strength structural alloys (up to 1200 MPa yield strength such as Hardox, Weldox, and Domex equivalents), stainless steel (grades 200, 300, 400 series), titanium alloys, copper, and surface-critical aluminum alloys. Every line is custom-configured around your exact coil thickness range, maximum strip width, strip yield point, and surface finish criteria.

The decision is driven primarily by target sheet throughput and surface sensitivity. A conventional cut to length (CTL) line stops the strip intermittently while the mechanical or hydraulic shear cycles. This is ideal for heavy plate (up to 25mm), short production runs, and applications where moderate line speed (30-40 m/min) suffices. A flying shear production line synchronizes the cutting carriage with the continuous movement of the strip. Because the material never stops, line speeds can reach 80 to 120 m/min without risk of slippage marks or roll indentation, delivering up to three times the sheet output per hour.

Yes. Wuxi Jianfa maintains a dedicated foreign technical service division. We dispatch senior mechanical, hydraulic, and electrical engineers directly to your plant site in the Americas, Europe, Middle East, Africa, or Asia. Our engineers oversee foundation placement, mechanical alignment, electrical integration, live material commissioning, and comprehensive hands-on training for your operating and maintenance staff. Remote PLC tele-service is also integrated for instant software diagnostics.

Absolutely. We strongly encourage client visits and third-party inspection agencies (SGS, TÜV, Bureau Veritas) to inspect machines at our 40,000 m² factory in Wuxi, Jiangsu Province. Our location offers direct expressway and high-speed rail access from Shanghai (approx. 45 minutes). You can witness mechanical test runs, hydraulic pressure trials, and electronic simulation before your machinery is packed in export-grade seaworthy framing.
