Drilling performance analysis of impregnated micro bit
نویسندگان
چکیده
Abstract. The cutting mechanical properties of impregnated diamond bit depend on the performance its elements. Aiming at factors affecting element bit, laboratory rock breaking experiment micro is carried out. results show that work ratio and unit wear first decrease then increase with particle size concentration when drilling sandstone; efficiency resistance are highest 125 %. decreases increases limestone; 100 With size, granite; 150

Surface Finish in Micro-drilling of Ptfe
Surface finish of engineering components plays a key role in their functionality, particularly where the size of the geometric features of the component decreases. This paper reports on such an application – the drilling of micro-holes in PTFE during manufacture of molds for use in the bio-medical field. These molds are used for production of silicone scaffolds requiring very large aspect ratio...

Instantaneous Frequency Measurement (IFM) devices are the essential parts of anyESM, ELINT, and RWR receiver. Analog IFMs have been used for several decades. However, thesedevices are bulky, complex and expensive. Nowadays, there is a great interest in developing a wideband, high dynamic range, and accurate Digital IFMs. One Digital IFM that has suitably reached allthese requirements is mono-bi...
متن کاملMicro-hole drilling with femtosecond fiber laser
In this paper, micro-hole drilling in ambient air is presented using fs fiber laser (750 fs & 1030 nm). Micro holes were fabricated in both transparent (glasses) and non-transparent materials (metals and tissues). Hole shape and morphology was characterized and evaluated with optical microscope and scanning electron microscopy (SEM). Debris-free micro holes with good roundness and no thermal da...
متن کاملInvestigation of Thermal Operational Regimes for Diamond Bit Drilling Operations (TECHNICAL NOTE)
This paper reviews existing studies and investigates thermal operational regimes of diamond bit during drilling operations. The operating temperature of the diamond core drill is studied under bench condition and an optimal thermal range are presented. Based on this study, it was noted that glazing of diamond tools is observed at temperatures less than 327°C, and normal wear of diamond tools is...
