English Overview of DCMT YZ735 and YZ7225 Inserts for Stainless Steel:
Product Description:
The DCMT YZ735 and DCMT YZ7225 are indexable turning inserts with a 55-degree diamond shape (ISO code: DCMT). They are specifically engineered with substrate, coating, and edge preparation optimized for machining various types of stainless steel, aiming to improve productivity, tool life, and surface finish.
Key Features and Specifications:
1.Insert Geometry (DCMT): This denotes a 55° diamond shape, 1/8 inch (3.97mm) inscribed circle size, with a positive rake angle and a molded chipbreaker. The "D" shape is versatile for turning, facing, and chamfering.
2.Cutting Material & Grade:
1)YZ735: This grade is typically designed for general-purpose machining of a wide range of stainless steels, including 200, 300, and 400 series. It offers a balanced performance between wear resistance and toughness.
2)YZ7225: This grade is typically engineered for high-speed machining and finishing of stainless steels. It often features a sharper edge and a coating optimized for higher cutting speeds and better surface quality.
3.Coating Technology: Both grades likely feature advanced Physical Vapor Deposition (PVD) coatings, such as AlTiN (Aluminum Titanium Nitride) or similar multilayer coatings. PVD coatings are preferred for stainless steel due to their smoothness, heat resistance, and ability to maintain a sharp cutting edge.
4.Edge Preparation: A critical feature for stainless steel machining is a honed or lightly chamfered cutting edge. This reinforcement (T-land or hone) protects the edge from chipping caused by the work-hardening tendency and low thermal conductivity of stainless steel.
Intended Applications and Machining Parameters
These inserts are suitable for turning, facing, and contouring operations on stainless steel workpieces.
1.Typical Applications: Machining components for the valves, pumps, food processing equipment, and chemical industry.
2.Machining Style:
1)YZ735: Suitable for medium to roughing cuts, offering stable performance under varying conditions.
2)YZ7225: Optimized for finishing and semi-finishing operations, where higher speeds and better surface finish are required.
3.Important Note: Specific cutting speed (Vc), feed rate (fn), and depth of cut (ap) recommendations depend on the exact stainless steel grade and machining conditions. These parameters must be obtained from the official manufacturer's technical datasheet.
