the use of podiatry drills, in the absence of engineering controls and personal protective equipment, is an occupational hazard to the healthcare provider.nail dust collected during foot care procedures performed in office settings has been found to contain keratin, keratin hydrolysates, microbial debris, and viable fungal elements, including dermatophytes most commonly trichophyton rubrum .
a file is a tool used to remove fine amounts of material from a workpiece. it is common in woodworking, metalworking, and other similar trade and hobby tasks. most are hand tools, made of a case hardened steel bar of rectangular, square, triangular, or round cross-section, with one or more surfaces cut with sharp, generally parallel teeth. a .
a meat grinder also called a 'meat mincer' in the uk is a kitchen appliance for fine chopping 'mincing' and/or mixing of seven trust or cooked meat, fish, vegetables or similar food. it replaces tools like the mincing knife, for example, which is also used to produce minced meat, filling, etc. the producer puts the minced food into a funnel, which is placed on the top of the grinder.
the filling and grinding process steps can therefore be combined in a single machine. this means that the filling product is moved by the vacuum filler and, during filling, it is chopped to the final grain size within the grinding system. an important application for inline grinding systems is dry sausage or fresh sausage production. minced meat lines
grading. grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage. the earthworks created for such a purpose are often called the sub-grade or finished contouring see .
abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay non-carious cervical lesions .it is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel, especially at the cementoenamel junction cej , undergoes large amounts of stress, causing micro fractures and tooth tissue loss.
the surface of the weld can be manipulated either by welding technique or by use of machining or grinding tools after the weld is completed. when reading a manufacturers technical dings, you might also come across weld dimensions. the weld can be sized in many different ways such as the length of the weld, the measurements of the legs of the .
filings are mostly a byproduct of the grinding, filing, or milling of finished iron products, so their history largely tracks the development of iron. for the most part, they have been a waste product. iron filings have some utility as a component in primitive gunpowder. in such a fine powdered form, iron can readily burn, due to its increased .
tolerances for cylindrical grinding are held within ±0.0005 inches 13 μm for diameter and ±0.0001 inches 2.5 μm for roundness. precision work can reach tolerances as high as ±0.00005 inches 1.3 μm for diameter and ±0.00001 inches 0.25 μm for roundness. surface finishes can range from 2 microinches 51 nm .
to fabricate an amalgam filling, the dentist uses a mixing device to blend roughly equal parts by mass of shavings of a silver-base alloy with mercury until the shavings are thoroughly wetted. the silver alloy is typically 40–70% ag, 25-29% sn, 2–40% cu and 0–2% zn when the alloy is formulated. zn is a scavenger and is mostly consumed .
grinding does not affect the hydraulic capacities of curbs and gutters on municipal streets. on the other hand, bituminous overlays fill curb and gutter, reducing drainage capabilities. citation needed diamond grinding should be applied to the portion of the pavement where restoration is needed.
human tooth sharpening is the practice of manually sharpening the teeth, usually the front incisors. filed teeth are customary in various cultures. many remojadas figurines found in part of mexico have filed teeth and it is believed to have been common practice in their culture.
an abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction.while finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. in short, the ceramics which are used to cut, grind and .
filing metalworking filing is a material removal process in manufacturing. similar, depending on use, to both sawing and grinding in effect, it is functionally versatile, but used mostly for finishing operations, namely in deburring operations. filing operations can be used on a wide range of materials as a finishing operation.
pavement milling cold planing, asphalt milling, or profiling is the process of removing at least part of the surface of a paved area such as a road, bridge, or parking lot. milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal.
a dental restoration or dental filling is a treatment to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants. they are of two broad types—direct and indirect—and are further classified by location and size.a root canal filling, for example, is a .
