Finishing is a basic requirement for obtaining the required surface quality in production of various components used many industries. A relatively new finishing process, called magnetic abrasive finishing, complex shaped surfaces. This article presents latest developments polishing and describes results obtained by research scientists based on their experiments field polishing.
Two finishing trials and a metabolism trial were conducted to evaluate level of supplemental degradable intake (crude) protein (DIP) in finishing diets on cattle performance, carcass characteristics, and ruminal metabolism. Finishing trials were conducted in two consecutive years using 128 crossbred yearling steers (BW = 343+/-5 kg, Trial 1) and 176 crossbred yearling steers (BW = 375+/-4 kg, T...
Objective. This study evaluated the effect of immediate or delayed finishing/polishing using different systems on the surface roughness, hardness, and microleakage of a silorane-based composite. Material and Methods. Specimens were made with silorane-based composite (Filtek P90, 3M ESPE) and assigned to the treatments: control (light-cured); aluminum oxide discs (Sof-Lex, 3M ESPE); diamond-impr...
Abrasive flow machining also known as abrasive flow deburring or extrude honing, is an interior surface finishing process characterized by flowing an abrasive-laden fluid through a work piece. This fluid is typically very viscous, having the consistency of putty, or dough. In this paper, the main purpose of the process is to investigate the surface finishing of die steel with the use of abrasiv...
Finishing methods of machining superhard composite’s working elements based on cubic boron nitride BL group are considered. The results the microgeometry formation research cutting inserts’ surfaces during by free powders synthetic diamond, grinding wheels and a method vibro-magnetic-abrasive (VMAM) presented. It is shown that VMAM friction between abrasive particles result in microremoval mate...
Obtaining the required surface finish and geometric accuracy together with attaining high production rate is a challenge in finishing of inner surfaces steel pipes bushes. One promising techniques for metal parts electrochemical machining. In this paper, roughness dimensional inaccuracy CK45 bush were controlled electrochemically. For this, special machine was constructed. The effect electric p...
Leather is used to make various daily life goods including footwear, clothing, automobile seats, furniture, etc. from prehistoric time. Various defects can occur either due failure of controlling the factors processing or low grade raw material both. The tanned leathers are, before use, necessarily being passed through different processes re-tanning, filling, coating surface with dyes, and othe...
Background and Aim: This study aimed to assess the effect of finishing and polishing time, technique and surface coating on microleakage of encapsulated restorative resin modified glass ionomer (RMGI). Materials and Methods: In this in vitro study, 40 freshly extracted human premolars were selected. Two standard class V cavities were prepared on the buccal and lingual surfaces of each tooth. T...
BACKGROUND The intracellular bacterium Lawsonia intracellularis is an important pathogen in modern swine production. The aim of this study was to investigate the effect of a live attenuated L. intracellularis vaccine (Enterisol Ileitis®) on the health and production parameters of weaned and finishing pigs in a commercial Finnish 850-sow farm with diagnosed L. intracellularis infection. The herd...
