Cemented Carbide Tool Milling Cutting Solutions
Problem | Reasons | Solutions |
Tool breakage | •Feed too fast •chip removal amount is too high •Blade or total length is too long •Excessive wear and tear |
•Reduce feed speed •Reduce the feed rate per tooth •A fixed shank deeper; using a shorter end mill •Early grinding |
Wear | •Speed is too fast •Harder workpiece •Chip stacking on edge •Incorrect feeding and speed (slow) •Incorrect Notching •The major clearance angle is too small |
•Reduce speed: using another lubricant •Use higher-level tool material and coating •Changing the feed rate and speed. Change the chip size or lubricant or air compressor to clear chips •Increase the feed rate and speed.Undercut feed •Switch to the correct cutting angle •With the larger clearance angle |
Short tool life (cutting edge passivation) | •Frictional force is too high while cutting •Workpiece is tough •Incorrect notching |
•Early grinding •Using advanced tool steel (the molecular metal polymer) •Switch to the correct cutting angle and clearance angle |
Blade notch | •Feed too fast •Feed is too fast in initial cutting •Insufficient rigidity of the machines, tools, or fixed appliances •Tool fixed is not strong •Fixing of the workpiece is not strong •Lack of rigidity •The blade is too sharp |
•Reduced to an appropriate feed rate •Deceleration in initial cutting •Switch to better rigidity machine, tools or fixed appliances •Indeed fixed •Indeed fixed •Use the shortest end mill, fixed shank deeper, incised feed •Reduce the clearance angle and cutting angle |
Chip stacking | •Chip removed too quickly •Chip removal lack of space •Lack of lubrication |
•Adjusting the feed rate or speed •Using fewer blade •Use of air compressor |
Burr | •Excessive wear of the main clearance angle •Incorrect milling set •Inappropriate Cutaway |
•Early grinding •Correct milling set •Switch to the correct cutting angle |
Edge no vertical degrees | •Feed too fast •Overcutting •Blade or total length is too long •Blade is too few |
•Reduced to the correct speed •Reduce the depth and width of cutting •Using the appropriate length of the tool, fixed shank deeper •Using multi-flute end mill |
Size is not accurate enough | •Overcutting •Machine or fixed appliance lack of accuracy •Lack of rigidity of machine or fixed appliances •Blade is too few |
•Reduce the depth and width of the cutting •Repairing the machine and fixed appliances •Change machines, fixed appliances or cutting set •Using multi-flute end mill |
Slot Miscellaneous | •Feed rate and too fast speed •Insufficient rigidity of the machine and fixed appliances •Clearance angle is too large •Workpiece fixed bad •Cutting too deep •Blade or total length is too long |
•Correct the feed rate and speed •Better machine or tool fixed appliances or change the setting •Reduce the clearance angle, edge processing (oilstone painted clearance angle) • Fixed workpiece •Reduce cut depth •The fixed shank darker, use the shorter end mill or try to switch to the incised feed |
Rough surface fine milling | •Feed too fast •Speed is too slow •Excessive wear •The chips piled at the edge to form cutting action •The end of the blade is not as chip removal surfaces |
•Reduced to the correct feed rate •Use higher speed •Early grinding •Reduce the chip removal amount •Blade at the bottom of grinding surfaces |
