| - a new perspective on feed and surface finish in turning | |
Generating a good surface finish on turned components has become a demand for semi-finishing and even roughing operations. The Wiper indexable insert technology has provided turning with a new means to achieve improved production performance where the key is to being able to raise the feed rate.
The generated surface finish and tolerance are effected by a combination of nose radius size, feed rate, machining stability, workpiece, tool clamping and machine condition. |

| The Wiper insert has a completely new type of nose configuration. It has been developed to provide a high capability of generating a better surface finish. Or, put another way, is capable of generating the same finish at a much higher feed. |
| Changing the feed rate can also lead to chip control being unsatisfactory, the cutting edge load excessive and tool wear too rapid. Yet feed rate remains the most direct way to lower actual machining times but does not have the marked effect on tool-life that cutting speed does. The Wiper technology is a direct means with which to improve productivity. |

GUIDELINES
Two times the feed rate
= Same surface finish
Same feed rate
= Twice as good a surface finish |
|
| Eliminate grinding
By using Wiper inserts you can achieve excellent surface finish and eliminate many grinding operations. You also get better component quality and roundness compared to grinding. The best surface quality is achieved when using a positive Wiper insert like the CoroTurn 107.

Surface quality in Parting & Grooving operations
The CoroCut geometries -CF/-TF generate excellent surface quality in parting, grooving and face grooving operations due to the unique Wiper radius on the insert.

 | FACE GROOVING

| Turning with a grooving tool
Itīs possible to make axial turning operations with the very stable CoroCut system. The main idea is to reduce the number of tools involved in the operation. When using geometries -TF/-TM the feed rate must be increased to tilt the insertin order to achieve the Wiper effect resulting in better surface finish quality and increased productivity. |
