CNMG CNC inserts for turning

Product Description

CNMG NC inserts for turning


cemented carbide cnc insert for turning, milling, cutting, grooving, roughing, grounding, polishing.

all kind of function for different machine and field



more display for all kinds of inserts:






Tungsten steel sintering process can be divided into four basic stages:
1: Removal of pre-burn phase forming agents, the following changes occur during this phase sintered body:
Removal of the initial sintering agent as the temperature rises, forming agent gradually decompose or vaporize,
excluded from the sintered body, at the same time, more or less to the sintered body forming agent by carbon,
carbon amount will vary depending on forming agent different type, quantity and sintering process change.
Powder surface oxides are reduced, at the sintering temperature, the hydrogen reduction of cobalt and tungsten
can be oxides, if removed in vacuo to a forming agent and sintering, carbon and oxygen reaction is not strong.
Contact stress between the gradual elimination of the powder particles, bonding metal powder begins to generate
recovery and recrystallization, surface diffusion began, briquette strength increased.
2: The solid-phase sintering stage (800 ℃ - eutectic temperature)
Temperature occurs in the liquid phase under the previous, except to continue the process of what happens on
stage, the solid-phase reaction and diffusion intensified, plastic flow enhancement, significant shrinkage
of the sintered body.
3: liquid phase sintering (eutectic temperature - the sintering temperature)
When the liquid phase sintered body appeared after contraction done quickly, then crystallization transition
form the basic organization and structure of the alloy.
4: cooling phase (sintering temperature - room temperature)
At this stage, the organization and the phase composition of tungsten steel with different cooling conditions
to produce some variations, can use this feature, tungsten steel heat treated to improve its physical and
mechanical properties.
