Big Difference In Micro Machining

MICRO DEFINED

Miniature tool edge geometries may not be visible to the naked eye, but they’re critical for machining quality and consistency. Diameters are available from RobbJack in every increment of .001.

• Cutting diameters starting at 0.005”
• Tolerances in microns (0.000039”), smaller than a human hair
• Hand-select diameters to nearest 0.0002”
• Primary relief angles maximize quality machining performance
• CVD diamond coating for certain applications

MINIATURE APPLICATIONS

• Micro-electromechanical Systems
• Nanotechnology
• Dental and Medical Appliances
• Die/mold
• Aerospace
• Electronics

MINIATURE TOOL USAGE

• Axial depth 25% of the tool diameter in Z-depth per pass
• Use accurate tool holders.
• Indicate the shank of the tool in.

MINIATURE TOOL MEASUREMENT

• Don’t use micrometers or calipers to measure tools. (use no contact measurement)
• Use shim stock for tool length measurements
