The Mirror Endmill

Product catalog summary

Overview: The document details specifications and applications for KORLOY's Mirror Endmill series, including PCD, cBN, and H-star Endmills, designed for high precision mold manufacturing. It also covers the ESLNB series of long neck ball end mills, providing technical specifications, recommended cutting conditions, and safety precautions.

PCD Endmill:

Designed for polishing high precision and high hardness molds.
Offers optimal surface finish with nano-level precision due to ultra-fine design.
Enhanced wear resistance through optimal PCD grade application.

cBN Endmill:

Suitable for ultra-fine, mirror-like finishes on workpieces and molds with hardness over HRC60.
Provides higher productivity and surface finish in high-speed cutting.
Improved wear resistance and longer tool life due to strong cutting edge design.

H-Star Endmill:

Ideal for various cutting processes including long neck, rib, and taper neck applications.
Features stronger cutting edge strength and enhanced high-temperature resistance.
Stable cutting performance for high-speed machining of workpieces with HRC50~63.

Specifications:

Includes detailed dimensions and tolerances for PCD and cBN Endmills, such as drill diameter, flute length, neck length, and overall length.
Recommended cutting conditions are specified for different hardness levels and cutting depths.

Application Examples:

Demonstrates the wear resistance and surface finish capabilities of the Endmills with specific tools and conditions for optimal results.

Customization:

Options for order-made tools are available, allowing customization of flute length and other specifications to meet specific machining needs.

ESLNB Series Specifications:

Lists multiple models with specific dimensions such as drill diameter, shank diameter, flute length, neck length, neck diameter, and overall length.
Provides tolerances for these dimensions to ensure precision in manufacturing and application.

Recommended Cutting Conditions:

Outlines cutting conditions for different materials, including carbon steel, alloy steel, pre-hardened steel, hardened steel, copper, graphite, cast iron, aluminum, and stainless steel.
Provides specific parameters such as spindle speed, feed rate, and depth of cut for optimal performance.

Application Examples:

Highlights the tool's performance in machining processes such as pocket machining on heat-treated steel, emphasizing wear resistance and chipping resistance.

Safety Recommendations:

Emphasizes the importance of safety during metal cutting operations, advising the use of protective gloves, safety glasses, and covers.
Highlights the need for proper clamping of workpieces and careful management of tool changes to ensure operator safety.

Contact Information:

Provides contact details for KORLOY's offices in various countries for further inquiries and support.

For the safe metalcutting Use safety supplies such as protective gloves to prevent possible injury while touching the edge of tools. Use safety glasess or safety cover to hedge possible dangers. Inappropriate usage or excessive cutting condition may lead tool's breakage or even the fragment's scattering. Clamp the workpiece tightly enough to prevent its movement while its machining. Properly manage the tool change phase PCDbecause Endmill the inordinately used tool can be easily broken under the excessive cutting load or severe wear, and it may threat the operator's safety. Use safety cover because...
