Constructed Sturdy, Steel, Small Lathe Chuck Shields –
These sturdily constructed small steel lathe chuck shields are fabricated of 18-gauge steel with reinforced sides and can be used on smaller lathes that have up to 18 1/2″ diameter chucks.
Each shield is furnished with a 1″ x 13″ mounting rod which can be cut to length if required. This mounting rod is fastened to the headstock of the lathe. The mounting rod is also used to hinge the entire shield. The shield can be lifted and swung up for quick and easy access to the chuck and the part being machined. This shield includes a high-impact polycarbonate window which permits visibility into the point of operation.
Remember to order a mounting bracket when purchasing small steel lathe chuck shields.
According to OSHA:
“There is no specific OSHA standard for lathe chucks. It has been, and continues to be OSHA’s policy that in the absence of an applicable specific standard for a machine, the general requirements for all machines, 29 CFR 1910.212(a)(1) shall apply. When there is a National Consensus Standard, it can be used as a guideline for applying the general requirements of 29 CFR 1910.212(a)(1).
There is a National Consensus Standard, ANSI B11.6-1975, Safety Requirements for the Construction, Care, and Use of Lathes. Section 5 of this standard contains the safeguarding requirements. Paragraph 5.3 states:
Work-Holding-Device Hazard. When the work holding or driving device in the clamped mode has components that extend beyond the outside diameter of the holding device; or the periphery of the body of the holding device is of irregular shape; or a pinch point is created and the operator is not effectively protected by location, machine components, or other means from coming into contact with these projections; a fixed or moveable guard, device, awareness barrier, or peripheral cover over area exposed to the operator shall be required.
Therefore, automatic or semiautomatic lathes used for production operations that have work-holding device such as a lathe chuck, operating under the conditions outlined in paragraph 5.3 of the ANSI B11.6-1975, requires a fixed or movable guard. All guarding methods stated in paragraph 5.3 are acceptable except the awareness barrier as this latter barrier does not meet the requirements of 29 CFR 1910.212(a)(1). All work-holding devices do not require guarding. Therefore, a thorough evaluation must be conducted of the work-holding device.”
