Feature of Carbide Metal

The characteristic of Solid carbide products

This meticulous manufacturing process allows excellent axial runout of side face and roughness, as well as dramatically improving the roughness of machined surface in contrast to the original high speed steel products.

The high speed cutting of varied materials such as nomal steel and cast iron saves time in the manufacturing process.

In contrast to high speed steel products, solid carbide products are far more resistant to wear. This means that tools are replaced less frequently, and at lower cost.

Cautions when using the products

  • As long as the cutting depth is not affected, please use the largest possible flange, and attach to the main shaft from both sides.
  • Metal slitting saws and screw slotting sutters become more and more vulnerable to vibrations and thrust stress as their thickness decreases. Therefore the machinery used should be in top condition.
  • Vibrations outside and from the side may cause problems. Therefore please make sure there are no external vibratinons.

Wear resistance

Toughness

Hard cast iron,
Chilled cast iron,
Thermal refining steel,
Cast iron,
Stone material
Used when wearing down from abrasive frictions (wear of flank face) is problematic, as opposed to damage from the heat caused by rough or hard surfaces.
K10Chilled cast iron,
Thermal refining steel,
Cast iron,
Aluminum alloy
Used for cutting cast iron.
It also lasts longer than other carbide grades for steel cutting, for interrupted wet cutting of steel and sensitive feed, thin depth of cut.
K20Cast iron,
Aluminum alloy,
Non-ferrous metals,
Wooden material
Best used when cutting non-ferrous metals in which small wedge angle and toughness is required.
Micro grain carbideZ01


Wear resistance

Toughness

Steel,
Cast iron,
Non-ferrous metals,
Non-metallic materials
Best used when cutting requires sensitive feed, thin depth of cut, high precision at low speed. Toughness is retained even though it keeps the hardness of the normal carbides because of micro structure. Best fit for precision machining of tools with small diameter and thickness.

※1 The processing difficulty is said to be “hard” when the material to be cut has uneven surfaces or hardness that requires varying conditions. The difficulty can also increase if the machinery, the cutting tools, and materials do not fit, or suffer from heavy vibrations.
