Cemented carbide can be machined withdiamond grinding wheels. When selecting the grinding wheels, the grain size, type of connection (synthetic resin,metal sintering,ceramic or galvanic bonds) and concentration represent important factors. The larger the abrasive grain: the higher the grinding forcesGet Price
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.
Hongxing rod grinder is especially suitable for crushing river gravel to make sand. It's a kind of effective and energy saving rod grinding machine.
The dryer machine has been mainly used for drying materials with some humidity and granularity in the fields, such as ore dressing, building materials, metallurgy, chemical industry, etc.
Cemented carbide has to bemachined by grinding with diamond tools or by electrical discharge machining (EDM). CTD has an extensive and state of the art machine parc with machines and technologies specifically adapted to machining of cemented carbide.
Cemented carbide is extensively used as cutting tool material because of the advantages it offers. Initiallybrazed cemented carbide tips were used which could be renewedbygrinding when cutting edge turned blunt. Brazing introduces stresses in the carbide matrix.Grinding of cutting edge also introduces grinding stresses in carbide.
Themicro grinding of the cemented carbides tool materialis rarely investigated. The cutting edge damage mechanism of the cemented carbides micro tools grinding are still unclear. Herein, the micro mills of cemented carbides grinding experiments are carried out.
Cemented carbides are ofgreat importance in the manufacturing industry, which havelong been used in applications such as cutting,grinding, anddrilling.
Alumina ceramicsand cemented carbides are ground bydiamond wheelin many cases. And a vertical spindle surface grinding machines with a rotary table are widely used for grinding of these materials. In these type of machine tools, a cup grinding wheels are usually used.
Routes of Exposure: Grinding cemented carbideproduct will produce dust of potentially hazardous ingredients which can be inhaled,swallowed or come in contact with the skin or eyes. Effects of Overexposure: Inhalation - Dust from grinding can cause irritation of the nose and throat. It has also has the potential for causing transient or permanent respiratory disease, including occupational asthma …
Thegrinding wheel is not deformed easily during the grinding process, and the comprehensive cost is lower than that of resin bond diamond grinding wheel. At present, cemented carbide tools are widely used, and the type of tungsten and titanium carbide is increasing, and their quality is constantly improving.

The workers are exposed to fume or dust from the cobalt used as a binder in thecementedtungstencarbidemetal. The usual symptoms are dyspnea on exertion, cough, and fatigue. The chest x-ray may show infiltrates, and the pulmonary function test may reveal a restrictive defect.
More specific aspects related to wheel weargrinding cemented carbides. Binder hardness connecting diamond abrasive grains and binder material porosity is relevant in determining the wheel’s capacity to grind. Porousgrindingwheels demonstrated a greater capacity than conventional abrades and are easier to balance and recondition.
It can be likened to concrete. Small stones (tungstencarbide) are surrounded bycement(cobalt).Cemented carbide, when sintered, will have nearly twice as high gravity, and about half as much volume as before the sintering process. Sinteredcemented carbideis ground by a diamondgrindingtool and can then be used as a cutting tool.

Cemented carbidescommonly use tungstencarbide(WC), titaniumcarbide(TiC), tantalumcarbide(TaC) or niobiumcarbide(NbC) as the aggregate.Mentions of "carbide" or "tungstencarbide" in industrial contexts usually refer to thesecementedcomposites. It is mainly used to make high speed cutting tools,cold working molds, measuring tools and ...
Cemented carbidesare nine kinds of metalcarbidesof IVa, Va and VIa groups in the periodic table of elements, and iron group metals such as Fe, Co and Ni are prepared by powder metallurgy. Thecarbidephase gives the alloy high hardness and wear resista
Thecemented carbidesare a range of composite materials that consist of hardcarbideparticles bonded together by a metallic binder. The proportion ofcarbidephase is generally between 70 and 97% of the total weight of the composite. Its grain size averages between 0.4 and 10 μm. Tungstencarbide(WC), the hard phase, together with cobalt ...

For example,grindingoperations usingcementedtungstencarbidesnormally need not be analyzed for soluble W. 1) Carefully remove the filter from the polystyrene cassette with forceps and place the sample filter, dust side up, on the moistened platform of a filtering apparatus.
Because of the high hardness,cemented carbidestools can be finished only by diamondgrinding.Cemented carbidetools are produced in insert form (sometimes with a molded-in chip groove geometry for ease of chip disposal and to reduce forces) by cold pressing to shape and nominal size, followed by liquid-phase vacuum sintering.
