Introducing Blade Technology

With the inflation cost nowadays, machine operators and manufacturers are constantly looking for a more cost-effective ways to cut steel. Fortunately, the sawing technology is continuing to improve every year. Today, we’ve seen new breed of sawblades that are designed to cut down manufacturing cost.

Blade Basics

Choosing the ideal blade for the material to be cut is extremely important in ensuring the cost-effectiveness of the sawing process. Today, we’ll give you some information to help you with your decision-making process.

·         Blade Back

This refers to the body of the blade, excluding the tooth portion

·         Width

The nominal dimension of a saw blade as measured from the tip of the tooth

·         TPI

The number of teeth per inch as measured from gullet to gullet

·         Thickness

The dimensions from side to side on the blade

·         Kerf

The amount of material removed by the cut of the blade

·         Set

The bending of the teeth to left or right to allow clearance of the back of the blade through the cut

·         Tooth Pitch

The distance from the tip of one tooth to the tip of the next tooth.

·         Tooth Rake Angle

The angle of the tooth face measured with respect to the line perpendicular to the cutting direction of the saw

·         Tooth Face

The surface of the tooth on which chip is formed

·         Gullet

The curved area at the base tooth. The tooth tip to the bottom of the gullet is the gullet depth.

Blade Construction

Band saw blades are made from a single piece of steel or built of two pieces. Your choice will largely depend on the life expectancy and performance requirements. Below are the key information you need to know about blade construction.

Bi-metal

It’s a blade composed of a high steel edge material. An electron beam is wielded to fatigue resistance spring steel backing. This specific construction is ideal for high performance cutting requirement and longer life fatigue.

Carbon

·         Hardback

A one-piece blade made out of carbon steel with a hardened back and tooth edge

·         Flexback

A one piece blade made of carbon steel with a hardened tooth edge and softback
