Wiper cutting edge design

When machining surfaces, customers often encounter problems such as unevenness or roughness. An effective solution to these challenges is the use of wiper inserts. These specialized inserts feature a wiper edge, located at the radius run-out, which enables uniform machining of the material.

How does the wiper edge work?

The wiper edge is a specially shaped secondary cutting edge that broadens the contact area on the workpiece beyond the feed per revolution. This leads to a significant improvement in surface quality. Compared to conventional inserts, surface roughness can be reduced by a factor of 2 to 4, even when the feed rate is doubled.

Advantages of the Wiper Geometry

Improved surface finish: The wiper edge ensures a smoother surface, which is particularly important in applications where a high surface finish is required.

Increased productivity: By enabling higher feed rates, machining time can be reduced, which increases productivity.

Extended tool life: The special geometry reduces wear on the cutting edge because it minimizes friction and provides better chip control.

 

Application Areas:

Wiper inserts are versatile and are frequently used for machining materials such as steel, stainless steel, cast iron, and other metals. They are particularly useful in die and mold making, where high surface finishes are required.

In summary, the use of wiper inserts offers an effective solution for resolving surface problems, by combining improved surface quality and increased productivity.

BN1000 Uncoated CBN

The BN1000 tool is a high-performance tool made from a exceptionally durable CBN (cubic boron nitride) material. This specific composition allows it to achieve exceedingly smooth surfaces during machining, which is particularly critical when addressing surface finish issues.

Benefits:

Superior Surface Finish: Thanks to the CBN material's high hardness and abrasion resistance, very precise and uniform surfaces can be produced. This is particularly important in applications requiring a high surface finish to minimize friction or meet optical requirements.

Enhanced Wear Resistance: The BN1000 offers exceptional wear resistance, meaning it lasts longer even under intensive use and needs to be replaced less often. This reduces maintenance costs and increases productivity.

Stable Machining: The combination of high hardness and wear resistance enables stable machining, even at high cutting speeds. This results in a consistently high surface finish throughout the entire machining process.

Adaptability: The BN1000 can be used in a variety of applications, from continuous cutting to interrupted cutting. It is particularly well-suited for machining hardened steels and offers high fracture toughness, making it ideal for demanding machining tasks.

By using BN1000, customers can effectively address their surface finish issues by achieving a consistently high surface quality while increasing machining efficiency. This leads to improved product quality and reduces the need for subsequent machining steps, which ultimately lowers overall costs and increases productivity.
