Spindle Speed Calculation

Formula: n (rpm) = (Vc × 1000) / (π × D)

Example for Steel: n = (50 × 1000) / (π × #82) ≈ 7,840 rpm

Example for Aluminum: n = (150 × 1000) / (π × #82) ≈ 23,520 rpm

Operating Guidelines

Pre-Machining Setup

Verify spindle runout is less than 0.005 mm at the tool tip
Use precision collets (ER11/ER16 class 1) or hydraulic chucks
Ensure workpiece is rigidly clamped to minimize vibration
Program a 0.2 mm dwell at hole bottom for blind holes
Use center drilling or spotting for holes deeper than 5xD

During Machining

Maintain consistent coolant flow (minimum 15 L/min external, 20 bar internal)
Monitor chip color — blue chips indicate excessive heat; reduce Vc by 10%
For peck drilling, retract to 1xD above bottom for chip break
Do not exceed recommended feed rates — micro-drills are sensitive to overload
Listen for chatter — if present, reduce speed by 15% and increase feed by 10%

Post-Machining Care

Clean tool immediately after use with soft brush and alcohol
Inspect cutting edges under 10x magnification for wear or chipping
Store in original packaging or foam insert to prevent edge damage
Re-sharpen only by authorized Kyocera service centers
Replace tool when flank wear exceeds 0.1 mm or edge chipping is visible

Safety Warning: Always wear appropriate PPE when handling solid carbide tools. Carbide is brittle — avoid dropping or impacting the tool. Do not use damaged tools as catastrophic failure may occur during cutting.
