Safety Precautions for Diamond / CBN Cutting Tools
1. Work Environment / Work Clothes / Protective Equipment
1. Work Environment / Work Clothes / Protective Equipment
it is not plugged and is set properly to provide sufficient coolant. Check overhang length does not surpass limitation Important notice ◎ May balance on machine after being attached to the machine ◎ May loose attachment of wheel and flange to screw by checking run-out of reference face close to abrasive layer
4. Trial Run
Warning Wheel guard must be properly attached Only authorized people attend around machine and do not stand at rotation direction Must wear dust-proof glasses, safety shoes, safety hat and appropriate clothes Caution Ventilate to remove mist coolant and dust Must wear dust-proof mask and ear plug Clean floor around grinding machine Instruct moving range of table of grinding machine etc. on the floor Do not put anything or stand within its moving area Do not operate in the area of inflammable object because grinding tools sparks in use
Warning Designated wheel guard must be properly attached Otherwise, in case tool is broken, serious injury may occur Only authorized people attend around machine Do not approach to the area of rotation direction and moving area of machine table Must wear dust-proof glasses, safety shoes, safety hat and appropriate clothes Sleeve or bottom of clothes need to be tight not to occur serious injury Must wear dust-proof mask and ear plug Do not operate in the area of inflammable object because tool sparks in use Caution Ventilate to remove mist coolant and dust Clean floor around machine
Warning Check tool is firmly attached and operation of feed mechanism work correctly Check work material is firmly attached and operation of feed mechanism work correctly Tool or work material breakage may occur injury Check rotation direction of tool It may occur injury if it is not correct Check irregular sound or vibration by no-load operation around 1-3 mins
4. Trial Run
Warning Check work material is firmly attached and operation of feed mechanism work correctly Check grinding tools is firmly attached and operation of feed mechanism work correctly Check rotation direction of grinding toolsl Check irregular sound or vibration by no-load operation around 1-3 mins Caution Check coolant is correcly supplied
2. Before Use
5. Grinding Operation
Caution Check grinding tools sizes to match with requirement of grinding machine Check apperance (crack, fracture, breakage etc.) after cleaning grinding tools Wash corrosion inhibitor in case grinding tools body is ferrous material Clean grinding tools mouting portion of spindle Clean flange and chuck to confirm no damage, warp and bend etc. Check warp and bend on grinding tools Read user manual and confirm grinding tools is for appropriate usage Please be sure to confirm if your grinder is designed for wet dressing before using diamoand rotary dresser. Please confirm before using diamond rotary dresser that both grinding wheel and dresser are run by consistent speed and dresser certainly feeds into grinding tool under the condition. Warning Turn off a switch when grinding tools is attached to spindle Attach grinding tools gurad appropriately Caution Check scratch and dust etc. around or inside of mounting portion of grinding tools , flange and chuck For grinding tools other than rotary dressers, remove fine scratches with sandpaper. Hold wheel with enclosed cushion material to prevent crack etc. in case of vitrified bond grinding tools Grinding tools and flange need to be smoothly attached Do not attach with force by hammering etc. Do not operate to change inner dia Please instruct us if necessay Screw flange by equable torque at the position of diagonal line Please check before running if body or diamond zone of grinding wheel will not hit grinder or drive unit. Please check run-out is less than 2μm at both outer diameter and end face with grinding wheel set on machine. After grinding tool is set, please make sure coolant nozzle to see if
5. Cutting Operation
2. Before Use
Warning Do not touch grinding tools when rotating
Warning Please use within peripheral speed stated Caution Check tool sizes to match with requirement of the machine Remove edge protection and store it in the case Check crack and breakage etc. after washing corroision inhibitor In case no irregular is confirmed, please attach edge protection Protection removes risk of crack or injury of user Clean mounting portion of main spindle Please inspect tool and cramp area to check if there is no contamination or dirt on it.
Warning Do not touch tool when rotating to remove risk of serious injury Make completed stop when irregular sound or vibration occured to remove risk of injury Cutting operation needs to be processed after reaching allowable rotation Turn off a switch of main spindle after completion of cutting process Do not touch or put object to stop rotating tool Turn off a switch when tool is taken out from main spindle Caution Confirm feed, D.O.C. and cycle time by trial run Be careful of overload Important notice ◎ Please consult us in case cutting condition or tool specification is not correctly chosen
Please be sure to use a dresser within available highest surface speed. Please be careful to handle dresser not to occur impact that is caused by hitting with grinding tool or larger feed rate. Please do not use rotary dresser and grinding tool designed for wet process in dry condition. Please stop operation and remove grinding tool as soon as unusual noise or vibration is recognized. Turn off a switch only after stopping coolant supply Do not touch or put object to stop rotating grinding tools Turn off a switch when grinding tools is taken out from spindle Please do not use dresser when unusual appearance is recognized after grinding and dressing process. Caution Be careful of excess cutting especially dry tool cutting
3. Attachment
Confirm feed, D.O.C. and cycle time by trial run Check burning or chatter mark on work material Be careful of overload
Please contact our sales team about dressing parameter such as preliminary rotation direction, relative circumferential speed ratio, speed of cut, amount of cut or amount of dress-out. Please be sure to run dresser by different surface speed from grinding wheel.
6. Storage and Handling
3. Tool Attachment
Warning Turn off a switch when tool is attached to main spind Please check left or right hand of cutting edge and direction of spindle. Check scratch and dust etc. around mounting portion of tool and request the manufacturer to investigate, if necessary. Wear the prescribed protective equipment when tools is attached Do not attach with force by hammering etc. Do not operate to change the shaft or hole diameter. Please instruct us if necessary Screw holder by equable torque at the position of diagonal line Please do not touch cutting edge by hand as it is very sharp.
Warning Attach edge protection Touching directly to cutting edge may occur injury Impact to tool may occur crack or breakage etc., which making it unusable. Caution Check irregular wear, breakage, crack, peeling etc. on working face Store storing in place after anticorrision treatment and edge protection etc. Do not operate to change tool shape. Please instruct us if necessary
6. Storage and Handling
Caution Check crack, scratch, breakage, burning etc. on working face Please inspect grinding tool body to check if there is damage such as scratch, deformation, crack or melting issue. Store dry area and prevent drop-off and crash etc. Apply corrosion inhibitor to ferrous grinding tools body to store Do not operate to change grinding tools shape. Please instruct us if necessary
