Moving machine parts have the potential to cause severe workplace injuries, such as crushed fingers or hands, amputations, burns, or blindness. Amputations, lacerations, and abrasions are costly and have the potential to increase workers' compensation premiums.   Amputation is one of the most severe and crippling types of injuries in the occupational workplace, often resulting in permanent disability. Due to this fact, OSHA (Occupational Safety & Health Administration) has established a set of standards around milling machine guards . The purpose of machine guarding is to protect the machine operator and other employees in the work area from hazards created during the machine's normal operation.   This would include hazards of concern such as: ingoing nip points, rotating parts, reciprocating, trans-versing, and/or flying chips & sparks. The Importance of Milling Machine Guards Any machine part, function, or process that might cause injury must be safeguarded. ...

Lathes are often overlooked when Risk Assessments are conducted to determine appropriate machine guarding. OSHA regulations consider lathes to be a 1910.212 machine, saying to the employer, “One or more methods of machine guarding shall be provided to protect the operator and other employees in the machine area from hazards such as those created by point of operation, ingoing nip points, rotating parts, flying chips, and sparks” but requirements are vague because they cover such a wide variety of machinery. Therefore, a reference to something more detailed, like ANSI B11.6 on metalworking lathe chuck guards , is required for specific safeguarding alternatives. How to Build Lathe Chuck Guards ? From a practical standpoint, the rotating chuck cannot be fully enclosed, unlike gears, sprockets, or chains which can and usually are completely covered, often by the machine’s manufacturer. However, that same lathe manufacturer may provide no safeguarding at or near the point of operati...
