Information Needed for Parameter Support
Prepare the following machining details to help us recommend suitable starting parameters.
Tool Model & Size
Diameter, flute count, coating and tool length.
Workpiece Material & Hardness
Material grade and hardness, if known.
Current RPM & Feed Rate
Current spindle speed and feed rate.
Cutting Conditions
Ap, Ae, hole depth, coolant and tool overhang.
Current Machining Issue
Chipping, chatter, short tool life or poor finish.
Recommended values are starting points and should be adjusted based on the actual machine, setup, and cutting conditions.
Troubleshoot Common Machining Problems
Review your current machining conditions to identify which parameters to check before changing the tool.
Short Tool Life
Check first: Cutting speed, workpiece hardness, tool engagement and coolant conditions.
Chipping or Tool Breakage
Check first: Feed rate, cutting depth, radial engagement, tool overhang and machine rigidity.
Chatter or Vibration
Check first: RPM, radial engagement, tool overhang, clamping condition and setup rigidity.
Poor Surface Finish
Check first: Feed rate, tool wear, runout, vibration and finishing allowance.
