Machine Column

• Heavy-duty, distortion-free welded construction

Fully Enclosed Workspace

• The KASTOverto A 2 is equipped with a fully enclosed workspace. A high degree of safety and cleanliness is achieved with best accessibility at the material infeed and outfeed side.

Saw Unit (Saw Frame)

• Distortion-free welded construction, modular design, with vibration optimised ribbing: Using the latest design, technology and manufacturing methods, an extremely quiet and vibration-free operation is achieved. This means shorter cutting times and longer blade life (foundation free assembly).

Guidance of the Saw Unit

• Two linear guide units with backlash-free carriages guarantee a high rigidity and cut precision. The greased guide carriages guarantee maximum usable life.

Saw Band Guidance

• Side guidance via mechanically preloaded carbide guides with quick release for fast band change. The band back is guided via rollers. Manual adaptation of saw band guidance arm to material cross section via scale.

Saw Band Tensioning

• Hydraulic, electrically monitored, with automatic pressure reduction at standstill of machine. Automatic stop in case of band breakage.

Cleaning of Saw Band

• Via chip removal brush, synchronised with cutting speed.

Chip Flow

• Plane and steep walls guarantee an ideal chip flow directly into the serial chip drawer or into the optional chip conveyor.

Clearance Stroke system for Saw Blade

• Before return stroke of the saw unit the material to be cut is retracted in automatic cycle from the cutting surface. The wear at the tooth tips is reduced, longer blade life can be achieved.

Material Clamping - Machine Clamping Vice

• The hydraulic and linear guided horizontal full stroke double clamping vice enables an optimum work piece clamping on both sides of the saw band, also for cutting of short remnant pieces.

Material Clamping - Feed Vice

• Hydraulic and linear guided horizontal clamping vice with integrated material-end feeler.

Automatic NC Material Feed

• Via linear guided feed vice. Safe material transport, even with forged work pieces. Material feed length 850 mm, standard multiple feed, short cut lengths up to 250 mm are achieved by an incremental feed. Material feed via ball bearing spindle.

Single Cuts or Small Series

• Single cuts can be realized under consistent compliance of all safety measures in the fully enclosed workspace.

Remote Adjustment of the Cutting Speed

• Central operation of the infinitely adjustable cutting speed 12 -120 m/min through switch +/- at the BasicControl.

SpeedControl (Electrical monitoring of low RPM)

• Below the minimum RPM, the machine stops automatically.

Material Infeed

• Via a continuous transport roller conveyor with 12 ball bearing transportation rollers, integrated into the machine.

Material Outfeed

Via large-dimensioned and easy removable support table of 400 x 300 mm as well as a replaceable coolant splash guard if necessary incl. the safety device.

• Hydraulic System
• In block design, exchangeable, built into the machine base and easily accessible from the outside. This reduces maintenance times for oil control and filter change to a minimum.

LED machine lamp

Coolant hose for machine cleaning

• With airgun

Clamping power regulation

• By means of handwheel with reading at pressure gauge

Vertical roller

• In extension with the material supporting edge, guarantees undisturbed material feed.

Mains voltage: In accordance with EN 60204; 400 V three-phase current (-10 %, +6 %); Control voltage 24 V-DC

Mains frequency: 50 Hz (-1 %, +1 %; transient –2 %, +2 %)

Type of mains: TN mains according to IEC 364/VDE 0100

The power is supplied from the mains to the switching cabinets including advance fusing by the customer. The position of the switch cabinet is to be seen from the lay-out.

Protective measures against indirect contact: Over-current protector (zero balancing). The mains supply of the operator (size and characteris-tic of the main fuse selected as well as the total imped-ance of PE and outer conductor in the supply line to the machine) has to be designed in such a way that the per-missible shutdown time in the event of an error is not exceeded. The use of a differential current switch in the mains in-coming supply is not permitted.

Safety requirements: The offered machine corresponds with the valid safety requirements according to the machinery directive 2006/42/EG

Subject to the individual conditions of use and to the in-stallation site, additional equipment such as fences, safety light beams and barriers in the area of material supply and cut-off removal may be necessary. Possibly, such additional equipments are not included in our scope of supply and must therefore be procured by the buyer.

Delivery terms: Possibly valid company’s own operating material regula-tions have not been taken into consideration when work-ing out the offer, unless they are specifically mentioned in the quotation. The machine will be equipped with proven components selected by KASTO. If you insist on the ob-servance of your operating material regulations we kindly ask you to make these regulations available to us for working out the appropriate offer. After placing the order, any specifications can no longer be considered. This is also valid for so called fire protection regulations.

Cutting accuracy: On perfect conditions with perfect tools the deviation of cut is within ±0.1 mm per 100 mm cutting height with standard steel qualities. For material with a perfect geo-metric surface an accuracy of length of cut-off pieces in accordance with ISO 2768-1, degree of accuracy fine is achievable with individual bars and cut-off pieces longer 6 mm. When using uneven, twisted or burred initial ma-terial, the achievement of the mentioned cutting accura-cies is restricted. The tolerance of length of cut-off pieces is valid for machines with automatic material feed.
