ER Collets: Professional Grade CNC Machine Tool Accessories for B2B Distributors

Created on 09.22

Product Overview: Understanding ER Collets

ER Collets represent a critical component in modern CNC machining operations, serving as precision workholding solutions for manufacturing environments. These cylindrical collets feature a split design that enables secure gripping of cutting tools and workpieces through radial compression. The ER system has become widely adopted across the machine tool industry due to its versatility, accuracy, and reliable performance in various machining applications.

OLICNC® manufactures professional-grade ER Collets designed to meet the demanding requirements of industrial machining operations. Our collets provide consistent gripping force while maintaining dimensional accuracy throughout extended production runs.

Technical Specifications and Material Options

Material Composition Options

OLICNC® ER Collets are available in two premium material configurations:

65Mn Carbon Steel Collets:

Material: High-carbon manganese steel (65Mn)
Hardness Range: HRC44-48
Precision Grades Available:

Grade I: ≤ 0.003mm runout
Grade II: ≤ 0.005mm runout
Grade III: ≤ 0.008mm runout
Grade IV: ≤ 0.01mm runout
Grade V: ≤ 0.015mm runout

4Cr13ER Stainless Steel Collets:

Material: Martensitic stainless steel (4Cr13ER)
Hardness Range: HRC50-55
Precision Grade: <0.008mm runout

Performance Characteristics

The 65Mn material provides excellent wear resistance and dimensional stability for general machining applications. The 4Cr13ER stainless steel option offers superior corrosion resistance, making it suitable for environments where chemical exposure or moisture may be present.

Critical Role of ER Collets in Machine Tool Operations

Industry Importance

ER Collets serve as fundamental components in CNC machine tool setups, directly impacting machining accuracy, surface finish quality, and production efficiency.
