Needle Chuck

A needle chuck is a specialized tool used to hold small cylindrical objects, most commonly needles, for various applications. It functions as a secure, temporary clamp, allowing for manipulation and work to be performed on the held item without damaging it.

Material:

Needle chucks are typically constructed from hardened steel, stainless steel, or brass. Steel provides high clamping force and durability. Stainless steel is preferred in applications requiring corrosion resistance, such as medical or laboratory settings. Brass is softer and less likely to damage delicate needles, often used in jewelry making or watch repair.

Purpose:

The primary purpose of a needle chuck is to provide a stable and firm grip on small cylindrical objects, enabling precise handling for operations like:

• Threading: Facilitating the threading of needles, particularly in sewing, embroidery, or surgical procedures.
• Insertion: Assisting in the precise insertion of needles into materials or components.
• Alignment: Holding needles steady for alignment purposes, such as in micro-assembly or electronics work.
• Extraction: Securely gripping needles for removal from materials or components.

Function:

A needle chuck operates based on a collet mechanism. This involves a tapered sleeve (the chuck body) with internal jaws that converge when rotated. When a needle is inserted into the chuck, rotating the chuck body causes the jaws to tighten around the needle, providing a secure grip. The clamping force is adjustable by the amount of rotation applied. Many designs incorporate a knurled grip for improved control during rotation.

Usage Scenarios:

• Sewing & Embroidery: Threading needles for hand sewing, machine sewing, or intricate embroidery work.
• Medical Procedures: Holding needles during suturing, acupuncture, or other surgical applications. Sterilizable stainless steel versions are crucial in this context.
• Jewelry Making: Holding small pins, wires, or needles for assembling jewelry components.
• Watch Repair: Securing small parts during watch assembly, disassembly, or repair.
• Electronics Assembly: Holding fine wires or pins during micro-assembly or soldering.
• Laboratory Work: Holding needles for precise injections, sampling, or other delicate procedures.
• Model Making: Holding small pins or wires for assembling models.

Common Types:

• Straight Needle Chuck: The most common type, featuring a straight body with a collet mechanism.
• Offset Needle Chuck: Designed with an offset angle to provide better access in confined spaces.
• Self-Closing Needle Chuck: Features a spring-loaded mechanism that automatically closes around the needle when inserted.
• Adjustable Needle Chuck: Allows for adjustment of the clamping force to accommodate needles of varying diameters.
• Threaded Needle Chuck: Features a threaded end for mounting onto a handle or tool holder.
• Micro Needle Chuck: Specifically designed for holding extremely small needles used in micro-assembly or electronics work.
• Plastic Needle Chuck: Often used for disposable applications, such as in medical settings, or for less demanding tasks.

Needle chucks are components used in sewing machines to hold the sewing machine needles. Based on the provided information, the following HS codes are relevant:

• 8452300000: This HS code covers sewing machines (other than book-sewing machines of heading 8440), furniture, bases and covers specially designed for sewing machines, sewing machine needles, and parts thereof. Specifically, it includes sewing machine needles. As a part directly related to the function of a sewing machine, a needle chuck would fall under this classification.
