Grinding and finishing of steel parts were done with a hand-held grinding machine or a band-grinder. The size of the handled pieces varied from cookware slabs diameter ∼30 cm to large pulp-processing tanks which the worker had to enter. Figure 1 shows an example of grinding with a hand-held tool.

Grinding wheels are rated for specific speeds. The maximum working speed for each wheel is printed on a tag that comes with the wheel. Know what speed your grinder operates at. If it is a variable-speed grinder know how fast each setting spins the wheel and do not exceed the manufacturer& 39;s recommended speed for the wheel you have mounted.
Abrasive grinding is the process of metal removal through abrasive action. Abrasive grinding is an effective method to remove material but there can be certain defects due to abrasive grinding and hazards related to abrasive grinding wheels. This article describes these defects and hazards related to abrasive grinding.
Switch off the machine when work completed. Remove milling cutters and store them safely. Before making adjustments and measurements or cleaning swarf accumulations switch off and bring the machine to a complete standstill. Leave the machine and work area in a safe clean and tidy state. POTENTIAL HAZARDS AND INJURIES. Sharp cutters.

In the early 2000s machine tool technology emerged that can alleviate the dangers of manual deburring and grinding reducing injury risk for employees. This approach to finishing metal parts focuses on a process that cleans up both sides of a metal part at the same time preventing the need to retrieve the part flip it and feed it through the ...
The reaction is similar to a fireworks explosion can create 4500ºF sparks and can occur when a grinder is used on ferric material e.g. steel prior to being used on an aluminum material or vice versa. This type of sparking and associated fire hazard may be eliminated by restricting the use of a grinder to only one type of material.
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 ...
