FEATURES

Structure

SHARK 230-1 NC HS 5.0	SHARK 350 NC HS 5.0
Saw head structure in grey heavy-duty cast iron (G25) that absorbs vibration and grants greater cutting stability and longer blade life. Saw head powered by a hydraulic cylinder.	Saw head structure in grey heavy-duty cast iron (G25) that absorbs vibration and grants greater cutting stability and longer blade life. Saw head powered by a hydraulic cylinder.
Saw head assembled on a linear guide with preloaded ball screw slides in the powered side and on a mechanical guide at the front.	Saw head assembled on double linear guides with preloaded ball screw slides.
Steel base equipped with: Removable drawer for chip collection that assures better operating conditions (it can be replaced by an OPTIONAL powered dredging chip conveyor to reduce downtime, thus preventing the interruption of the manufacturing process linked to the manual waste disposal). Nozzle to keep the working surfaces clean. Electric pump for the coolant. Tank allowing to recover the coolant.	Steel base equipped with: Powered dredging chip conveyor applicable on the right or left side of the machine. Nozzle to keep the working surfaces clean. Couple of triphasic electric pumps with high capacity (120 l/min) to cool off the blade, continually wash the working surface, conduct the chips in unloading and thus to ensure longer blade life. Tank allowing to recover the coolant.

Material clamping

SHARK 230-1 NC HS 5.0

SHARK 350 NC HS 5.0

Machine equipped with a clamping device only in the infeed side.

However, the sawing machine can be equipped with a split vice (OPTIONAL) to grant burr-free cuts.

Standard machine equipped with a split vice to clamp the material either in the infeed or the outfeed of the sawing machine, thus granting burr-free cuts.

Burnished and knurled steel jaws of both cutting and feeder vices to grant a proper clamping of the piece to cut.

Burnished and knurled steel jaws of both cutting and feeder vices. Moreover, the jaws of the cutting vice can be replaced.

Feeding system

SHARK 230-1 NC HS 5.0	SHARK 350 NC HS 5.0
Bar feeder with stroke 500 mm 19" (repeatable to cut at any length): cast-iron structure, stepper motor, screw assembled on preloaded opposing taper bearings and ball screw.	Cast-iron bar feeder with stepper motor and ball screw. Multi-indexing up to 600mm (23") in a single stroke with automatic blade kerf compensation.
Speed of the feeding vice: 4 m/min	Speed of the feeding vice: 4.5 m/min

Additional information

SHARK 230-1 NC HS 5.0	SHARK 350 NC HS 5.0
Manually-operated blade tensioning through electronic transducer displayed on the console. It ensures greater cutting precision and longer blade life.	Blade tensioning through a servo system constantly monitorized during the cutting cycle that ensures greater cutting precision and longer blade life. This system constantly monitors both blade tensioning during the cut according to the value set and its automatic releasing when in rest mode.
Self-regulation in real-time of head down feed rate according to the type of material or blade wear.	Self-regulation in real-time of head down feed rate according to the type of material or blade wear.
Upon request, the machine can be equipped with the following kits: Industry 4.0 Ready - IOT which allows to maximize data collection and use them in favor of a better sawing machine cutting performance and longer blade life. Kit MES which allows to add, manage and transfer production orders from the office directly to the sawing machines in the production department. It also enables remote monitoring of the various working phases as well as the machine status.

The machine can be equipped with the "Material Handling System" line: in particular, the sawing machine is suitable for products of the KK Line, entry-level line keeping the heavy-duty structure and both mechanical and electrical modularity from the K line.	The machine can be equipped with the devices of the "Material Handling System" lines designed by Mep: on the one hand, there is the entry-level KK line; on the other hand, there is the K line, our top line thanks to its heavy-duty and highly customizable structure.

DO YOU STILL HAVE DOUBTS?

Both machines are automatic band sawing machines for 0° cuts and they have been designed to meet the needs of mechanical workshops. However, while the Shark 230-1 NC HS 5.0 stands out for its optimized footprint (actually, the machine has a footprint of 2.5 sqm only); the Shark 350 NC HS 5.0 is characterized by high cutting speed and precision and it is ideal for medium-sized cutting (with sizes up to 350 x 350 mm).
