Work order is to include: | instructions for sharpening and aligning blades and knives in designated equipmentand may also include:instructions for the environmental monitoring of work and proceduresenvironmental care requirements relevant to the work |
Appropriate personnel may include: | supervisorssuppliersclientscolleaguesmanagers |
Sharpening | is the angle, depth of cut, and speed that the knife or blade passes over the grinding wheel to obtain a sharp edge and required surface finish |
Equipment is to include: | procedures for equipment lock-out, such as protecting operators and co-workers from accidental injury by isolating the machine from the power sourceand may include:grinding machines and babbitt making equipment, such as melting pots |
Alignment | is the process of setting blades or knives so that all blades and knives sit at the same angle and height in relation to the abrasive wheel |
Communication may include: | verbal and non-verbal languageconstructive feedbackactive listeningquestioning to clarify and confirm understandinguse of positive, confident and cooperative languageuse of language and concepts appropriate to individual social and cultural differencescontrol of tone of voice |
Cutting performance | is how the knife or blade performs in relation to production expectations |
Knife holder | is the assembly that houses the knife when positioned on the machine chuck during sharpening |
Pre-startup checks | are conducted to ensure:machine has been set up correctlysystems are performing accurately machine is operating to optimum performance |
Babbitts | are the spacers that extend from the backs of knives and blades to determine knife extension and position in relation to the disc or knife holder in the machine |
Defects may include cutting edges with: | burrsburnschipssplitsdents |
Geometry is to include: | angle that a knife or blade is sharpened at allowing for the device the knives or blades are in and the material they will be cutting |
Grinder attachments are to include: | grinder mounted tables or blade holders:with or without clampswith or without automatic feed |
Wheel speed | is the speed at which the grinding wheel rotates - too fast and it may burn the metal, too slow and it may produce a rough finish or grab the knife or blade |
Coolant | is used in conjunction with grinding operations to cool the metal blade or knife as it generates heat from the sharpening process |
Burrs | are thin raised sections of metal that extend from the cutting edgemust be removed through a honing process before the knife or blade commences cutting |
Dealing with may include: | recycling blades and knives that cannot be sharpened or are damaged in the process and cannot be repairedsending blades and knives that cannot be sharpened or are damaged in the process and cannot be repaired to waste |
Records and reports may include: | knife or blade type and sizeinspection informationgrading and labelling outcomesstorage locationsquality outcomeshazardsincidentsequipment malfunctionsand may be:manuala computer-based systemother appropriate organisational communication system |
Reconditioning | is the process of removing, melting and re-pouring babbitt material to the correct width, length and thickness |
Pouring temperature | is the temperature at which the molten babbitt metal can be poured into a mould without solidifying at an early stage of the babbitt forming process |
Set screws | are the spacers that extend from the backs of knives and blades to determine knife and blade extension and position in relation to the disc or knife holder in the machine |
