Guidelines offered to choose the best
saw
When is it best to use a bandsaw or a circular saw for cutting-off? A saw manufacturer says that while both techniques are complementary it is difficult to choose and offers guidelines.
Missler, manufacturer of bandsawing machines since 1980, are continually improving bandsawing systems by building machines with numerous innovations such as autoregulation, dual drive etc Today, Missler also offers sawing technology using Carbide and high speed steel circular blades with machines as technically advanced, as those with a bandsaw blade for instance, 3 numerical axis, automatic setting etc Both technologies are complementary

High production circular saw makes quality cuts
Fully automatic high production sawing machine, with a carbide and high speed steel circular saw, offers three-axis CNC and vibration damping for quality cuts.
Steel prices on the rise - time to review sawing
Confronted with global price increases and scarcity of raw materials, namely steel, users of sawing machines have to revise processes and speed up their productivity programmes.
However choosing is sometimes difficult.
Below is an objective analysis that may be of use when deciding which machine.
Capacity - this comparison is for capacities less than 100mm only, over which, except for specific cases, the bandsaw blade is best.
Productivity - without question, circular sawing is faster than bandsawing.
Nevertheless, the cutting capacity of the bandsawing machines enables cutting several bars at a time, in layers and bundles.
In this case the production becomes identical, even higher for the bandsaw blade.
Quality - the sawn pieces precision is better with a circular saw (about +/-0.05mm) whereas with a bandsaw blade it is +/-0.1mm.
The surface finish is much better with the circular blade: Ra 1.6, versus Ra 6.4 with the bandsaw blade (average values).
Cost - owing to higher tool costs, the cost per cut price is higher with a circular blade than with a bandsaw blade, but this cost can be justified in several circumstances * When a surface finish equivalent to a milled finish is required.
* When the sawn pieces must be free from swarf and coolant.
* When a robot is used to handle the sawn blanks as one piece at a time is easier to handle than a stack.
Exhibited for the first time in France at Simodec 2004 and Industrie 2004 this new Missler model CS4 circular sawing machine with Carbide blade will be demonstrated along with Missler DEB CE bandsawing machines.
