Features and uses of Ceramic Cutting Blade

Posted by Tom Brady on November 23rd, 2022

All Ceramic Cutting blades have excellent wear resistance at higher cutting speeds. There are wide ranges of Ceramic Cutting blades available for a variety of applications.

The Oxide ceramics are aluminum oxide-based, with added zirconia for crack inhibition. This generates a substance that is chemically very stable but deficiencies thermal shock resistance.

Mixed ceramics are particles strengthened through the addition of cubic carbides or carbonitrides. This improves toughness & thermal conductivity.

The Whisker-reinforced ceramics use silicon carbide to dramatically increase the toughness & enable the use of coolant. Whisker-reinforced ceramics are perfect for machining Ni-based alloys.

Silicon nitride ceramics represent another group of ceramic materials. The elongated crystals form a self-reinforced material with higher toughness. Silicon nitride grades are positive in grey cast iron, but a lack of chemical stability limits its use in other workpiece materials.

Features of Ceramic Cutting Blade:

It has a silver brazed blade

The metal bond of the Ceramic Cutting Blade is strong

It has high-quality diamond grit

Benefits of Ceramic Cutting Blade:

It has high cutting efficiency & precise cutting

It has a fast-cut speed

It is suitable for wet & dry cutting application

Properties of Ceramic Cutting Blade

It has good wear resistance, higher temperature resistance, and can achieve stable processing;

 It has good wear resistance and impact resistance, & the metal removal rate is much high than that of cemented carbide tools;

Various standard blades are available

A coating process is provided to ensure a long service life under high-speed cutting.

The benefits lead to increases in efficiency. The ceramic grade tools are typically classified into three general categories.

The Oxide ceramics are alumina-based & are generally used in roughing and concluding applications of the cast and grey irons. Progressively, oxide ceramics are being used in dry machining applications at higher speeds. This is due to the advancements in materials science, including the incorporation of whisk-based materials.

Nitride ceramics exhibit high fracture toughness & are used for roughing & semi-roughing of cast irons under harsh conditions when there is considerable starting and stopping that would characteristically increase fracturing. It contains ceramics mixed with other harder materials like cemented & titanium carbides. The ceramic cutting wheel can contain reinforcing whiskers and additional materials to increase wear resistance & toughness under very hot machining conditions. These ceramic cutting wheels are usually referred to as whisker-reinforced. Alumina reinforced with whiskers is the toughest & most resistant to thermal shock of the oxide-based ceramics due to the very high tensile strength of the whiskers. The ceramic cutting wheel offers the extra benefit of being able to be run without coolant, making dry machining a common application while being able to offer an increase in machining rates up to 800%.
