Overview
The refurbished Heavy Duty Board Cutter CONTRAIL 320 is a laser-guided, blade-based cutting system for fast, clean cutting, trimming and scoring of large rigid sheets up to 320 cm long and 30 mm thick. Brand indicated on the page: SALLMETALL. The machine is refurbished, inspected, cleaned, tested and restored to reliable working condition by Crest and validated by the original manufacturer, offering proven cutting performance at a lower investment than a new unit.

Key specifications (from product header)

• Max. cutting length: 320 cm
• Max. product thickness: 30 mm
• Max. cutting speed: 60 cm/s
• Machine height (upright position): 410 cm

Materials & cutting capabilities
The CONTRAIL 320 handles a wide range of rigid materials: it fully cuts softer and mid-density boards such as foamcore and Gatorfoam (up to 19 mm), foamed PVC (Forex) up to 10 mm using the heated blade, and rigid polystyrene and cardboard up to 3 mm. It scores clear rigid polystyrene, acrylic and glass up to 4 mm to enable clean snapping. Other substrates are often possible, as the machine was developed and tested in Crest's R&D department.

Features & operation

• Laser-guided cutting line for accurate alignment
• Teach-in function for repetitive work
• Adjustable acceleration and adjustable pressure bar for precise, repeatable results
• Variable speed feature and blade guide in rear carriage to handle harder substrates
• Blade-based cutting technology eliminates saw/router dust and fumes (no extraction required for the cut itself)
• Short cycle times, high cutting speed and easy knife changes suited for batch production

Installation & service requirements
The machine requires a 230 V, 50–60 Hz power supply and a compressed-air supply of 6 bar at 200 l/min during operation. In upright working position it stands 410 cm high and 280 cm wide over the rulers and weighs approximately 340 kg; plan floor space and access accordingly.

Frequently asked questions (summary)

• What is it used for? Fast, clean cutting, trimming and scoring of large rigid sheets including materials that historically required saws or routers (e.g., Gatorfoam, foamcore, foamed PVC, polystyrene, acrylic, glass).
• What does refurbished mean? Pre-owned machine fully inspected, cleaned, tested and restored to reliable working condition by Crest and validated by the original manufacturer.
• How does it cut without dust/fumes? Blade-based cutting eliminates the dust and fumes produced by saws and routers.
• Difference between cutting and scoring? The machine fully cuts softer/mid-density boards and scores harder/brittle materials to allow clean snapping.
• Maximum cutting length and speed? 320 cm and up to 60 cm/s. Upright design keeps footprint compact while handling full-size boards in a single pass.
