  • Machine Enclosure according to the latest CE Criteria
    • The KASTOwin A 3.3 is equipped with complete enclosure. A high degree of safety, cleanliness and low-noise cutting is achieved with best accessibility on the material infeed and outfeed side.
  • Saw Unit (Saw Frame)
    • Manufactured in robust weldment without distortion, with ribbing optimized against vibration. By using the latest constructional technology and manufacturing methods, an extremely quiet running without vibration is obtained. This means shorter cutting times and longer tool life.
  • Guide of the Saw Unit
    • Linear guide with two guide carriages on one guide rail. The recirculating ball unit consists of one solid pretensioned roller running system.The greased guide carriages ensure a maximum usable life.
  • Saw Blade Guide
    • Lateral guiding by hydraulically pretensioned carbide slideways, with clearance stroke system for fast exchange of saw blade. Back guiding by rollers. Automatic adjustment of the blade guide in accordance with the width of the material to cut.
  • Clearance Stroke System for Material
    • After a cut has been finished in automatic cycle the clamped material to be cut is retracted on the infeed side by approx. 2 mm from the saw blade by means of a clearance stroke system for material (to prolong blade life).
  • Adjustment of the Saw Unit’s Height
    • Start of cutting operation and cutting height can be adjusted either via teach function or automatically via the entered material diameter.
  • Saw Blade Tension
    • Hydraulic, electronically monitored with automatic pressure reduction if the machine is out of operation, automatic switching-off if the saw blade breaks.
  • Swarf Removal at Saw Blade by motor-driven, self-adjusting Chip Brush
    • This smart mechanical system adjusts itself over the complete lifetime of the chip brush. The brush is thus always in its optimal position, which extends its life considerably.
  • Material Clamping - Machine Vice
    • The hydraulically actuated horizontal vice enables an optimum work piece clamping on the outfeed side of the saw blade and cutting of short remnants.
  • Material Clamping - Feed Vice
    • Hydraulically actuated horizontal vice with integrated material limit switch.
  • Automatic, Numerically Controlled Material Feed
    • Via feed gripper system. Material feed length 500 mm. Standard multiple feed. Short cut lengths up to 250 mm are achieved by an incremental feed. Material feed via servomotor and ball bearing spindle.
  • Operation
    • All operating elements are arranged centrally and ergonomically at the front side of the machine.
  • Material Feeding
    • By a roller conveyor, integrated into the machine.
  • Material Outfeed
    • Via deposit table. Transfer height 700 mm, container height max. 650 mm.
    • The material outfeed side meets the effective European and international safety standards. A safety inspection of the complete machine has been performed by the German Professional Association and the French Apave.
  • Hydraulic System
    • Compact system in block construction, removable, integrated into machine base and easy to access and check from outside. In that way, maintenance time for oil-level control and exchange of filter can be minimized.
    • This extremely energy-saving system only runs when required.
  • Coolant Tank
    • In machine base. Coolant supply through nozzles at the blade guides.
  • KASTOrespond
    • The new KASTOrespond system, especially designed for this machine line, provides ideal settings of the machine for solid materials, pipes and profiles of all material types and is available for all sizes of the KASTOwin series.
    • The system continuously records the forces on the tool without using an additional and often error-prone sensor system. It intelligently converts information into the optimum digital downfeed speed. Thick-walled and thin-walled material, constantly changing contact length in round material as well as hard spots in solid materials are recognized on time by KASTOrespond and the feed speed is smartly adapted accordingly. The operator only needs to program the relevant data such as the cutting lengths, the quantities and the type of material to be cut. Everything else is taken care of by the KASTOwin.
  • Diagnosis of performance and energy consumption
    • Recording and display of the current data of performance and energy consumption based on non-recurring measuring values for basic functions as well as the calcula-tion of motor performance of all drives during the running process.

Included optional equipment:

  • Saw blade dimensions 5090 x 41 x 1.3 mm
  • Safety Package
    • Recommendable if the machine partly works in unmanned shift, consisting of:
    • Supervision of the non-driven blade running wheel by SpeedControl (electronic supervision of minimum number of revolutions). If the minimum number of revolutions is too low, e.g. by reason of a blade break, the machine stops automatically.
    • Supervision of deviation of cut by BandControl. If a programmable value of deviation is exceeded, the machine stops automatically.
    • Supervision of coolant quantity by FlowControl. If the coolant flow rate is too low, the machine switches off automatically.
  • LED machine lamp
  • Automatic zero positioning start/KASTOsense
    • After having entered the requested cut-off length and number of pieces and after having activated the control function “zero positioning”, the first cut-off piece is at once positioned fully automatically at the requested cut-off length and then cut. The system is designed for material heights from 30 mm.
    • Function expanded by two additional types to start:
      • “Automatic zero positioning start”: Put the leading edge of the material to any position in the outfeed vice and start the cutting job. The first cut-off piece will be positioned automatically to the cut-off length.
      • “Automatic zero positioning start for remnants”: same as “automatic zero positioning start”, but the material is not clamped anew in the infeed vice.
    • These types to start are possible from a material height ≥ 30 mm.
    • They are selectable and deselectable. When they are deselected, the types to start “Manual zero positioning start” and “Manual zero positioning start for remnants” are active.
    • KASTOsense:
      • Automatic recording of the material height from any position of the saw feed in all types to start.
      • With all types to start, except for zero positioning starts, the recording is active also for restart of cutting operations that have begun already.
    • KASTOsense is possible from a material width ≥ 30 mm.
    • KASTOsense is not possible for very easy to cut special materials (e.g. plastics, partly aluminium).
    • KASTOsense is selectable and deselectable.
  • KASTO worm-type chip conveyor
    • Ejection height 450 mm
  • Performance package
    • For cutting of predominantly difficult to cut material qualities, power 5.5 kW, total power 8 kW, V = 12 – 150 m/min.
  • Coolant hose for machine cleaning
    • With spray pistol
  • 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.
  • Clearance stroke system for material feed and machine vice
    • In order to be able to guarantee safe transport of forged material as well, the fixed vice jaw at the machine vice is automatically retracted from the guide edge by approx. 10 mm during material transport movement (clearance stroke system).
    • During return stroke movement, the fixed vice jaw of the material feed vice is retracted automatically by approx. 5 mm from the guide edge. By the clearing stroke system, the remnant length is reduced to 35 mm.

    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.


    This sawing machine is particularly suitable for easily to normally machinable materials in solid material, tubes and profiles. Only conditionally suitable are materials that are difficult to machine as well as plastics. An application up to two-shift production operation is envisaged. The specified cutting ranges and performance characteristics must be observed. The use of uneven, twisted or burred starting material can severely impair the cutting accuracy. For more detailed information on the correct use of the machine, please refer to the operating instructions. Disregarding this area of application and/or General Terms and Conditions can lead to the warranty claims becoming void.
