Application:
| The Chipbreaker Instruction of Carbide Indexable CNC Turning Inserts | |
| DF | Chip-breaker with special angle design can make cut easy,control chip and get good surface quality. |
| DM | Widely used chip-breaker is used for semi-finishing and finishing machining steel and stainless steel. |
| DR | Special chip-breaker with high toughness cutting edge can reduce cutting force. |
| PM | With stronger cutting edge,it is better for intermittent cutting than -DM,with widely cutting zone of P type material. |
| HF | With sharp cutting edge,used for finishing machining inner hole,fine finishing surface can be got with small feed rate. |
| HM | With sharp wave cutting edge to reduce cutting force,it is the first choice for semi-finishing machining of inner holes and can make chip flow smoothly. |
| HR | With tough cutting edge,used for roughing/machining of inner hole and intermittent machining workpiece with irregular surface. |
| LH | Mainly recommended for finish turning,Typical parts: Ordinary aluminum parts. |
In addition to normal milling operations, there are certain applications that are particularly damaging to carbide. Here are some of the most difficult jobs that demand a lot of strength from the shape of the insert:
Clearly the shape of the round insert is the major reason for its strength and reliability. One major reason for the success of the round insert in so many applications is that the axial and radial cutting forces can be managed by changing the axial depth of cut. A high radial cutting force can cause vibration and chatter. Conversely, a high axial force can cause the workpiece to move in its fixturing and cause poor tolerances. With the use of traditional milling cutters, the lead angle dictates the kind of cutting force produced.
Multiple Cutting Edges
A milling insert is limited to the number of indexes by its number of corners. A round insert, on the other hand, is able to provide many cutting edges. It all depends on how deep the cut is. The fewest edges available would be where the insert is "buried" at one-half the IC of the insert -- this would provide four edges. The maximum amount of edges can be as many as eight or more for very light cuts. Thus, the per-index cost of a round insert is less than an insert with three or four indexes.
In the past, it was difficult for an operator to index to a new edge with a round insert. After loosening the insert screw, he would have to "eyeball" to find the new cutting edge. Recent insert pressing advancements have allowed some manufacturers to press-in location facets into the back of the insert (Figure 6). With these facets, the operator gets a true, distinct index every time he goes for a new edge. This way the guess work is taken out, and all of the insert may be utilized. The facets also help to hold the insert in the pocket, keeping it from rotating under heavy loads.
