SUMITOMO T2100Z steel turning

SUMITOMO T2100Z steel turning

Core technical characteristics of the brand

Matrix: A newly developed alloy matrix for high-strength and tough metal ceramic substrates, effectively suppressing crack propagation; The anti collapse blade (fracture resistance) reaches three times that of traditional metal ceramic grades, breaking through the shortcomings of the old metal ceramic models that were afraid of intermittent impact.

Absotech coating system, coating thickness 3 μ m, HRA hardness 92.0, TRS flexural strength 2.2 GPa

High adhesion coating technology reduces coating peeling;

The blade edge is smoothed to directly obtain excellent machining surface roughness.

Comparison of positioning intervals with the same series of metal ceramics

Key focus of brand positioning

T1000A uncoated metal ceramic high-speed continuous precision machining, almost unable to withstand interruptions

T1500A uncoated metal ceramic universal continuous precision car

T1500Z coated metal ceramics focus on wear resistance and are suitable for continuous use

T2100Z (new) coated metal ceramic with wear-resistant and anti collapse balance, can be lightly to moderately intermittent

T2500Z coated metal ceramic universal, medium load

T3000Z coated metal ceramics focus on rough machining and have low cutting speeds

T2100Z fills the gap in "intermittent processing of metal ceramics": not only can it be used for continuous precision machining, but it can also be used for light intermittent working conditions with notches and slight casting and forging oxide scales. Compared with hard alloy AC8000P, T2100Z is more suitable for pursuing mirror finish machining; When the main form of processing damage is sticking to the knife, hard alloy is preferred; In the future, the wear of the cutting surface will be the main issue, and the advantage of T2100Z is obvious.

EGU medium cutting, inner and outer circular, weakly rigid boring

MESI/MEFC small part dedicated groove type for walking machines (CCGT/DCGT/VCGT, etc.)

The sample is accompanied by AP-F chip breaking window diagrams for each groove type, distinguishing the applicable feed cutting depth range for negative M-level, negative G-level, positive M, and positive G blades.

Performance test results (all wet cooling, steel)

Continuous outer circle wear test (4135 steel) shows that the wear of the rear cutting surface is much smaller than that of traditional metal ceramics and competitor A after the same processing time; the tool life is 1.5 times that of traditional grades and 2 times that of competitor A.

Surface quality comparison (4118 end face turning) T2100Z starting Ra=1.6, after wear Ra=2.5; Compared to traditional grades, the starting Ra is 1.9, and after wear, Ra is 2.5; The roughness is maintained better throughout the processing process, and the surface degradation of the workpiece is slower after blade wear.

The intermittent impact test (4135 steel intermittent outer circle) can withstand more than three times the number of impact fractures of competing brand numbers; Traditional metal ceramics are prone to chipping under intermittent conditions, but the T2100Z significantly improves this.

Tip: Metal ceramics are not suitable for large cutting, deep and rough machining; Priority wet; Intermittent working conditions require a reduction in cutting speed.
