◆نظرة عامة على المنتج
إن Carbide Turning and Milling Inserts for CNC Machining range covers indexable cutting inserts for external turning, facing, profiling, roughing, semi-finishing, finishing, shoulder milling, face milling, and other production operations. Common turning families include CNMG, DNMG, SNMG, TNMG, VNMG, and WNMG, while APMT and other dedicated geometries are used with compatible indexable milling cutters.
The insert shape alone does not define the application. Size, clearance angle, tolerance, corner radius, chipbreaker, carbide grade, coating, and holder or cutter-pocket compatibility must be checked together. For shoulder and face milling, compare the APMT1604 / APMT1135 milling insert series.

◆Turning Inserts vs. Milling Inserts
Both products use indexable carbide cutting edges, but their motion, clamping systems, geometry, and loading are different. They must be matched to the correct holder or cutter body.
إدخالات الخراطة الكربيدية
The insert is clamped in a stationary toolholder while the workpiece rotates. Shape and included angle determine edge strength, access, profiling capability, and the number of usable cutting corners.
- ◆External turning and facing
- ◆Roughing, semi-finishing, and finishing
- ◆Profiling, chamfering, and contour access
Carbide Milling Inserts
Multiple inserts rotate with the cutter body and repeatedly enter and leave the cut. The insert must withstand cyclic impact while maintaining pocket seating, chip evacuation, and edge-height consistency.
- ◆Face and shoulder milling
- ◆Slotting, side milling, and profiling
- ◆High-feed and specialized indexable operations
◆Common Insert Families & Their Roles
The descriptions below are general geometry guidelines. The complete ISO code and manufacturer suffix determine the actual dimensions, corner radius, tolerance, chipbreaker, and grade.
| Family | General Shape | Main Strength | Typical Use |
|---|---|---|---|
| CNMG | Strong diamond turning insert | Balance of strength and accessibility | General external turning, facing, roughing, and semi-finishing |
| DNMG | Narrow diamond turning insert | Improved profile access | Profiling, contour turning, semi-finishing, and finishing |

◆Match the Grade to the Workpiece
◆Insert Geometry & Coating Details
◆Coating, Chipbreaker & Edge Preparation
PVD-Coated Grades
Often selected when edge sharpness, coating toughness, and lower cutting pressure are important. Suitability depends on the substrate and application.
CVD-Coated Grades
Commonly chosen for strong wear and heat resistance in stable steel or cast-iron machining. Edge requirements must still be confirmed.
Chipbreaker Geometry
Controls chip formation within a defined feed and depth range. A roughing chipbreaker should not be treated as a finishing geometry, or vice versa.
For high-productivity milling with shallow axial engagement, compare the
LNMU / ENMU / BLMP double-sided high-feed inserts.

◆Product FAQs
What is the difference between turning and milling inserts?
A turning insert is held in a lathe toolholder while the workpiece rotates. A milling insert rotates with a cutter body and repeatedly enters the cut. Their pocket, clamping, geometry and cutting data must be selected for the corresponding tool system.
Which turning insert families does this range cover?
The Overview names CNMG, DNMG, SNMG, TNMG, VNMG and WNMG as common turning families, plus APMT and other cutter-specific milling geometries. These are range examples, not a complete list of stocked codes. Send the full model for an exact size and grade check.
Can inserts with the same shape or ISO size be substituted?
Matching shape and nominal dimensions are only the first checks. Compare the complete code, thickness, corner radius, fixing hole, chipbreaker, grade, edge preparation and holder or cutter-pocket fit. Test the candidate under the actual cutting conditions before approving a production replacement.
How do I select a grade for steel, stainless steel or cast iron?
Provide the exact workpiece grade and hardness, operation, continuous or interrupted cut, coolant and current wear pattern. Then match a supplier-defined carbide grade and chipbreaker. ISO material groups are starting categories; a family name alone does not identify an approved grade.
Should I choose PVD, CVD or an uncoated insert?
The suitable surface treatment depends on the substrate, edge preparation, workpiece and cutting load. Confirm which coating is offered for the complete code and use its recommended operating range. A similar-looking coating does not establish equivalent performance.
Where can I find exact insert dimensions and cutting parameters?
This broad product page does not contain a verified size chart for every turning and milling family. Request the selected series drawing and grade-specific cutting data using the full insert designation and holder or cutter-body model. The APMT1135 / APMT1604 series provides a focused milling reference.
◆Ordering & OEM FAQs
Can I order different insert models together?
Send a line-by-line list with each complete insert code, grade and quantity. Mixed-model supply, minimum quantities and lead times are confirmed by item. The Overview lists 10 pieces per box as a reference; the actual pack quantity can differ by model.
What should I send for an insert replacement request?
Provide the original manufacturer and complete code, grade and chipbreaker, box-label photo, insert photos from both sides, holder or cutter-body model, workpiece, cutting conditions, observed wear and required quantity. This allows dimensional and application review before a sample trial.
Are private-label packaging and custom specifications available?
The Overview lists OEM and ODM services. Send the requested grade, geometry, marking, label artwork, packaging, quantity and target application for feasibility review. The approved drawing and quotation should identify the actual specification and lead time.
Can I request samples before a larger order?
Include the full codes, holder details, material and trial conditions with your inquiry. Confirm sample availability and quantity by model, then compare wear, finish, chip control and cost per accepted part under consistent machining conditions.
