Sheet Cutting Machine

A: The feeding table and leveling rolls are wrapped in high-density polyurethane or equipped with non-contact pneumatic lift guides. Additionally, an optional motorized PVC film applicator can laminate protective plastic film onto the top surface immediately before the uncoiling phase.

A: The guillotine shear uses a cassette-style quick-change blade holder. Operators unbolt the pneumatic locking gibs, slide out the worn blade assembly using an extraction trolley, and insert the pre-calibrated replacement set. The entire process takes approximately 30 to 45 minutes, minimizing line downtime.

A: Yes, provided the material specifications are defined prior to order placement. For high-yield steels (e.g., high-tensile automotive grades up to 700 MPa), we re-engineer the leveling section with smaller-diameter, closely-spaced backup rolls and upgrade the main shear cylinder tonnage to prevent springback distortion.

A: Standard configurations require a 3-phase power supply (typically 380V/415V/480V, 50/60 Hz with total connected load around 45 kW to 90 kW depending on line width), a compressed air supply of 0.6 - 0.8 MPa (500 L/min) for pneumatic gates/brakes, and a dedicated hydraulic oil reservoir fill (ISO VG 46 anti-wear hydraulic oil, approx. 300-500 liters).

A: The system utilizes a dual-loop control architecture. While the servo motor drives the feed rolls based on encoder pulses, an independent measuring wheel rides directly on the moving metal sheet surface. If micro-slippage is detected between the roll drive and actual sheet movement, the PLC applies real-time dynamic compensation before the shear triggers.

A: Standard configurations (e.g., 1500 mm width, 3.0 mm thickness) typically require 90 to 120 days of manufacturing, assembly, and testing time. Highly customized lines involving automated coil storage integration or heavy-gauge specifications (>6 mm) require 150 to 180 days.
