KASTOhba U Semi-Automatic & Hydraulic Bandsawing Machine

• Hydraulic horizontal clamping vise with side shift cylinder of the fixed clamping jaw
• Saw head and band guides adjust automatically via light barriers to material height and material width.
• Hydraulically preloaded carbide slide guides of the saw blade
• Hydraulic and electronic control of saw blade tensioning
• Protective fence on infeed side

The large bandsaws of the KASTOhba series combine modern machine tool design and KASTO’s extensive experience in the efficient, cost-effective cutting of large workpieces. This combination results in exceptionally solid construction, high rigidity and extremely good vibration dampening, short cutting times and high cutting performance. These are the outstanding features for effective utilization in the engineering industry and tool manufacture, heavy industry, shipbuilding and forging as well as in the steel production and steel service centre industries.

Three machine sizes cover the cutting ranges from 1.060 x 1.260 mm (KASTOhba 10 x 12) to 1.320 x 1.720 mm (KASTOhba 13 x 17). All three sizes are available as semi-automatic machines KASTOhba U and as fully automatic machines KASTOhba A. For the larger models there are either roller conveyors with feed vices for handling of very long work pieces, or NC-controlled movable ball screw feed tables in the delivery program. Upon request, additional well-thought-out equipment for cutting with carbide tipped saw blades is available. A wide range of accessories allows any model of machine to be tailored to the tasks at hand.

The outstanding rigidity of the saw head (a composite construction of steel and polymer casting) ensures superb vibration dampening, quiet running of the saw blade and high cutting accuracy. The KASTOhba twin column machines cut profiles, tubes and solids up to a width of 1.720 mm fast and very clean. The superior stability of the polymer casting construction is especially important when sawing difficult to cut materials, resulting in shorter cutting times and longer saw blade life.

Automatic material feed is assured with accurately controllable ball screw. Precise, large dimensioned guides guarantee accurate material feeds at all times. The saw feed takes place at ground and hardened rails via adjustable, pretensioned rollers or playfree, virtually friction-free linear guides. This ensures constant and repeatable feed values.

• Higher blade speed: 15 - 190 m/min, required power 18 kW
• Adaptable, extremely strong gearbox for saw blade drive
• Hydraulic separation of band clamping and band guide
• Special blade guides for carbide tipped blades
• Adaptable saw feed control for beginning and end of cut
• Control of minimum rpm
• Adjustable chip removal brush; optional: automatically self-adjusting brush

Carbide packages are available for each size of the KASTOhba!

• Special cutting speeds
• Extended saw feed control for feeds less than 1 mm/min for extremely difficult to cut material
• Central lubrication system
• Preselectable automatic incline of saw unit by 1°. Ideal for trim cuts of forged or scaled material.
• Extension of material support table up to 6.000 mm (236.22”)
• Additional, strong horizontal vice
• Device for perpendicular set-up and clamping of short, heavy remnants: Two electro-magnets and an electronic control unit
• Hydraulic alignment device with separate hydraulic unit to align heavy workpieces on the infeed table
• Heavy-duty, rail-guided material cart for long shafts
• Pendulum operation for fast change between two workpieces (table version)

Fast and safe cutting

The KASTOhba 13 offers a cutting range of 1.320 x 1.320 mm with square material. With an 11 kW saw drive, the bi-metal or carbide tipped saw blades cut even difficult to cut material efficiently. The hydraulic horizontal vice offers a side shift cylinder of the fixed clamping jaw for safe material transport. The KASTO EasyControl with memory for repeat cutting jobs and characteristic material features for operating the fully automatic KASTOhba A 13 contributes considerably to economical cutting, providing at the same time an extraordinary safety package.
