Hydraulic Semi-automatic

Pivot semi-automatic bandsaw machines – machines are equipped with a high-performance industrial hydraulic unit. The whole cutting cycle – work piece clamping, switching-on the saw blade, cutting, saw blade stop, raising the arm to the initial (adjustable) position, vice opening – takes place after pressing a single switch. This, in connection with a hydraulic feed into the cut, substantially increases the cutting productivity, especially of full materials. Individual control of all functions also available. Manual work piece feed.  S.A.F.  versions are equipped with stronger motor and frequency changer, which provides for an optimum blade speed control between 15 – 90 m/min. Optimum setting of the sawblade speed improves the machine productivity, cutting accuracy and saw blade lifetime.

Types marked with a plus are fitted with a more robust vice system with a dual range of cutting angles of 60 ° to the right and 45 ° to the left, as opposed to the standard version that allows for a continuous adjustment of the saw blade arm only unilaterally within 90 ° and 60 ° to the right. Vice pressure control is also part of all  ARG S.A.F.  machines.

RECOMMENDATIONS WHEN CHOOSING A BANDSAW FOR METAL CUTTING

The main, essential criterion for the choice is the size of the saw blade. 

Saw blades are manufactured in the following standard sizes: 13×0,65; 20×0,9; 27×0,9; 34×1,1; 41×1,3; 54×1,6; 67×1,6…
In general, the larger the diameter of the material, and the greater the volume of the cut pieces – the bigger the saw blade.

As an example, we will use full material with the diameter of 100 mm, grade 11 600, DIN ST 60-2.

1. Individual pieces in a month
Saw blade 13×0,65 mm, manual bandsaw for metal cutting ARG 105 mobile, ARG 130, cutting time approx. 9 min.
This saw blade is not manufactured in higher quality, M 51, that is suitable for cutting of high-grade materials.

2. Dozens of pieces per month
Saw blade 20×0,9 mm, gravity bandsaw for metal cutting ARG 200 (plus), cutting time approx. 4 min.
This saw blade is not manufactured in higher quality, M 51, that is suitable for cutting of high-grade materials.

3. Hundreds of pieces per month
Saw blade 27×0,9 mm, gravity bandsaw for metal cutting ARG 235 (plus), ARG 260 (plus E), ARG 300 (plus) F., or the hydraulic-gravitational type H., cutting time approx. 2,5 min.
Starting from this size, the saw blades are manufactured in many tooth designs that enable cutting of all material types.
Saw blade 34×1,1 mm, gravity band saw ARG 330 (plus), cutting time approx. 2 min. Cutting in bundles possible.

4. Approx. thousands of pieces per month
Saw blade 27×0,9 mm, semi-automatic bandsaw for metal cutting ARG 260 (plus) S.A.F., ARG 300 (plus) S.A.F. or CNC automatic machines ARG 260 CF-NC, ARG 300 CF-NC, cutting time approx. 2 min.
Saw blade 34 x1,1 mm, semi-automatic bandsaw ARG 330 (plus) S.A.F., ARG 380 plus S.A.F., ARG 400 plus S.A.F., 2-column semi-automatic ARG 330 DC S.A.F or 2-column CNC automatic ARG 330 DC CF-NC, cutting time approx. 1,5 min. Cutting in bundles possible.

5. Thousands of pieces per month
Saw blade 34×1,1 mm, bandsaw for metal cutting 2-column CNC automatic machine ARG 330 DC CF-NC, cutting time approx. 1 min. Cutting in bundles possible.

Cutting times are indicative. They depend on the tooth size, optimum cutting speed and wear of the saw blade. There is a number of options here. The choice depends on the overall range of the material. There are usually more options for the choice of the size and type of the bandsaw, which also implies the price of the machine. Our specialists of the Sales Department will be happy to help you with the selection of the optimal bandsaw according to your needs.
