SUMITOMO ELECTRIC AC1030U Material Blade

Core features and advantages of the product

Coating and substrate structure

New multi-layer PVD coating (Absotech Bronze): 4-layer functional structure 1) Smooth anti collapse layer: achieving excellent workpiece surface quality; 2) High hardness heat-resistant layer: enhances wear resistance; 3) High adhesion technology: prevents coating peeling off; 4) Strong and tough hard alloy matrix: significantly resistant to chipping.

Compared to conventional blades and competitor blades: AC1030U blades have no breakage after processing; Competitors and ordinary brands have coating defects.

Excellent surface quality during processing

The blade has undergone high-quality edge grinding, with an Rz of 0.65 μ m for AC1030U; Ordinary grade Rz=1.20 μ m.

4137 steel outer circle precision machining test: AC1030U without tearing, Rz=2.0μm； The ordinary blade Rz=4.1 μ m and the competitor Rz=4.3 μ m both have machining tear defects.

It can suppress micro chipping and material adhesion, greatly improving the roughness of the processed surface.

The applicable cutting speed SFM range for machining intervals is about 165-650SFM, suitable for high-precision machining scenarios. Compared with other Sumitomo grades such as AC520U, AC530U, AC6040M, ACZ150, AC1030U focuses on high-precision precision machining of small parts.

Recommended cutting parameters (in English units SFM/IPR)

Processing material cutting speed Vc (SFM) feed f (IPR)

Soft steel 165-500 0.0008-0.006

Carbon steel 165-500 0.0008-0.004

Stainless steel 165-500 0.0008-0.004

Brass 230-1000 0.002-0.008

Cast iron 160-650 0.0008-0.004

Special alloy 100-200 0.0008-0.004

The processing conditions are generally wet cooling.

Actual Processing Cases

304 stainless steel processing: Vc=330SFM, f=0.002IPR, ap=0.004 “; AC1030U has less wear on the back cutting surface, and the Rz roughness of the workpiece is maintained at a low level throughout the process, with better stability than ordinary blades and competitors.

1047 steel stator shaft: AC1030U single blade can process 140 pieces, while ordinary blades can only process 70 pieces.

304 stainless steel valve body; 430 stainless steel sensor housing: AC1030U can process 1600 pieces, while ordinary blades only have 800 pieces, significantly improving the lifespan of individual cutting tools.

Introduction to chip breaker

The manual is divided into two categories: Handed Chipbreakers and Neutral Chipbreakers, providing applicable cutting depth and feed window diagrams for each slot type.

FX/FY/FYS (Left and Right Hand Slot Type)

FYS: For soft materials, improve chip removal, resist crescent wear, reduce edge damage, suitable for fine cutting, 15 ° groove angle.

FY and FX are used for precision machining of outer circles/inner holes with different feed cutting depths.

MESI/(M) EFC/(M) EFM (Neutral Slot Type)

Code prefix M: represents negative tolerance tool tip radius.

EFC, EFM, and MESI are suitable for neutral and non directional precision turning.
