Grinder Machine Hazards All types of grinding machines, whether pedestal, bench mounted, free-standing or portable, can be potentially hazardous if they are not well maintained and used correctly. In addition to the common hazards of flying particles, dust and sparks, shattering abrasive wheel while in Motion can cause severe injury to both the ...
Deburring is a type of finishing for removing burrs, irregular edges, and flashes. One method of deburring is through mechanical equipment. Mechanical deburring machines create abrasion imparted by an abrasive media placed together with the part inside a chamber. The chamber is agitated by vibration or tumbling.

PEF: This image extension stands for Pentax Electronic Format, a RAW image file type created by Pentax Digital Cameras. Working with images is a lot more complicated than you'd think at first glance. Hopefully this guide has provided a better understanding of the standard file types and which are most appropriate for your project.
An essential for beginners. A flat file has (you've guessed it) a flat surface and is used to file larger, flat areas of metal, to straighten up edges, and to work on the outside curve of a ring. With your flat file, you should always use a forward …
JPEG is the most common format used by digital cameras and images living on the World Wide Web. This file format is based on lossy compression, meaning that it keeps information that is visible to the viewer and gets rid of data that the human eye can't perceive.The popularity of the JPEG file stems from the fact that it is lightweight, while still being good …
THREAD GRINDING-Produce very accurate threads on hardened materials-Three basic methods are used. 1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ).
