Abstract:
The deep hole honing is an effective and precise method in deep hole processing. It can remove the machining allowance to ensure the hole size and the shape accuracy, and have better surface quality of a hole. The difficult-to-cut materials such as precipitation-hardening stainless steel, stainless steel (1Cr18Ni9Ti) and titanium alloy have the properties of high hardness, wear resistance, heat resistance, and corrosion resistance. The conventional single-abrasive honing stones can not handle the difficult-to-cut materials effectively because of their single-abrasive property. For higher effic

In this paper, a new truing method is proposed instead of the conventional mechanical truing that has low truing rate for metal bonded diamond grinding wheels. In the proposed method, the metal-bond diamond grinding wheel is rubbed by a steel truer rotating at high speed. Generated frictional heat increases the oxidization and the diffusion of carbon into the steel truer, then diamond grains are thermally attrited on the wheel surface, so that the machinability of wheel is improved. Subsequently, high truing rate is achieved by mechanical truing with abrasive stones. These experiments are cond

Abstract:
Tillage machines such as plow, cultivator, rotavator, and rototiller are widely used for this purpose. However, one of the major problems in working with tillage machines is the wear of active parts over time. Abrasion occurs differently in active parts of tillage machines and can cause the machines used to lose the functionality expected of them. It is preferred to cover the active parts with wear-resistant coating materials to reduce the level of wear to meet both agro technical demands and high tillage efficiency. The way of wear the active parts of the machines; it is abrasive wear caused

Abstract The article analyses the method of testing the abrasion resistance of sandstones on Böhme abrasion test apparatus and describes the problems related to the implementation of this test, as well as the interpretation of the results. The tests were conducted in accordance with the requirements of the EN14157 standard on 14 samples of dry and water-saturated sandstones. The analysis of the results showed that the correlation coefficient for the results obtained in the case of dry samples tests in relation to water saturation was 0.944. It was also observed that the loss of volume during t

Abstract:
The diamond honing oilstone was fabricated by hot-pressing at 550–650 °C and 25 MPa pressure for 4 min, using Cu–Sn based alloys as binder metal and uncoated or W-coated diamond grains as abrasive material. The microstructures and phase compositions of the honing oilstone were examined and analyzed by SEM and XRD. Effects of the oilstone composition, sintering temperature and volume fraction of diamond grains on the mechanical properties of diamond honing oilstone were investigated. The experimental results show that the interfaces between the diamond grains and metal matrices of all the oilst

Several 40-year anniversaries of the modern area of the synthesis of diamond at high pressures and temperatures (HPHT) have come and gone. If you are a proponent of the Norton Company, this first synthesis would be somewhere between 1948 and 1950. ASEA's Feb. 15, 1953, accomplishment was noted at an international meeting in 1993 on high pressure (AIRAPT) with a small session that included papers by ASEA and General Electric (GE) representatives. The GE success in the Hall experiment of Dec. 16, 1954 (announced in February 1955), was marked only in the personal memories of the remaining members

Abstract:
Esthetic effects can be achieved by using color pigments or decorative stones in special concretes such as glass fiber reinforced concrete (GFRC). These special materials transform concrete from a purely structural element into a means of esthetic expression. Colored pigments allow concrete to be customized in a variety of colour palettes, moving away from grey tones, while decorative stones add textural richness and visual variety to the surface. The use of chemical solutions to remove the surface of concrete to reveal aggregates is called 'etching' or 'surfacing'. The 'Non-Corrosive Concrete

In this study, the durability and freeze-thaw strength of concrete paving stones produced from Ahlat stone powder and marble powder were increased by the special curing method. Six different types of paving stones were fabricated for study and were subjected to two different curing regimes. Tests of water absorption, splitting tensile strength, surface abrasion, and freeze-thaw were carried out for the specimens. In 3 days and at 20

Trevor Evans was responsible for revealing the main physical processes which take place in natural diamond both in the upper mantle of the earth, where it is stabilized by high pressure and temperature, and as it is ejected by volcanic action to the surface. By measuring the activation energies required for graphitization, he clarified the reason for its very long life as a metastable crystal, valuable both as a gemstone and as an industrial abrasive. He learned how to make diamond specimens for examination in the transmission electron microscope, which enabled his discovery of dislocation loo

Excavator bucket tool is one of the most important parts of an excavator. It is made of steel mixture. It is commonly equipped with protruding teeth on its cutting side to breakdown hard materials and also to prevent dryness and damage of the bucket. Excavator bucket tooth must have supporting geometrical shape to penetrate and to endure the digging process on the ground, gravels, stones, or any other abrasive field. It is because of the field’s natural characteristic when the bucket tool grinds the material. Mixed iron is common to be used as excavator bucket tool’s material because it is eas

The largest grinding stone from 34 randomly selected potholes, developed on the riverbed of Subarnarekha River at Ghatshila, Jharkhand, India, were analyzed to have an insight into 1) their sizes and shapes; 2) controls on grinding stone shape; and 3) roles of largest grinding stone on streambed pothole growth.
