Situo Hardware specializes in custom micro collet chucks and CNC machined mini tool holder precision mechanical tool accessories, focusing on precision clamping parts for automated dispensing equipment, micro drilling tools, miniature grinding devices, instrument tooling and precision testing jigs.
Product Overview
All micro collet chucks are integrally CNC machined from high-strength stainless steel and alloy steel. Featuring high concentricity, uniform clamping force and stable elastic opening performance, our micro collets solve common defects of standard collets such as eccentricity, slipping, unbalanced clamping and short service life.
We provide full non-standard custom sizes and structures for ultra-small precision tooling and micro equipment assembly scenarios.
Core Product Advantages
Precision One-Piece CNC Machining
One-piece CNC turned and milled in a single clamping process ensures zero secondary processing deviation, zero mold tolerance and zero residual internal stress. Excellent batch consistency and interchangeability meet micron-level precision clamping requirements.
High Concentricity & Vibration-Free Clamping
Smooth inner clamping surface ensures uniform roundness and ultra-low center deviation. Firmly locks micro cutters, thin shafts and pin parts without shaking, eccentricity or slipping during high-speed operation.
Precise Elastic Slot with Stable Rebound
Precisely cut and finely polished elastic gaps with symmetrical slot structure provide balanced opening and contracting elasticity with durable reset performance, resisting fatigue failure and deformation.
High-Strength Wear-Resistant Material
Dense solid stainless steel and alloy tool steel with professional heat treatment achieve high hardness, excellent toughness and strong fatigue resistance, maintaining stable clamping accuracy under demanding conditions.
Full Non-Standard Customization
Customize ultra-small bore collets, extended/shortened collets, stepped outer diameter collets, multi-slots elastic chucks and special-shaped micro clamping holders according to specific equipment requirements.
Strict Precision Quality Control
All finished micro collet chucks pass concentricity testing, roundness calibration, dimensional inspection, elastic performance testing and simulated equipment clamping tests with batch qualified rate over 99%.
Application Scenarios
Precision micro cutter clamping collets for automated dispensing, drilling and grinding equipment
Mini tool holders and micro shaft clamping accessories for small precision machinery
High-precision elastic collet chucks for instrument jigs and micro tooling modules
Anti-eccentric clamping parts for micro rods, thin pins and miniature cutting tools
Custom non-standard micro clamping tool accessories for special small-scale equipment
Service & Production Capacity
Situo Hardware provides full-process CNC custom machining for micro collet chucks and precision tool holder accessories. Our production covers raw material selection, integrated CNC precision machining, elastic slot optimization, heat treatment hardening and strict quality inspection.
We support 3-5 days rapid prototyping, flexible small-batch orders and large-scale mass production. Inspection reports and export-grade packaging are available for global cross-border delivery.
Frequently Asked Questions
What is a micro collet chuck used for?
A micro collet chuck is a high-precision CNC machined elastic clamping accessory, mainly used for clamping and positioning micro cutters, thin shafts and tiny components in automated dispensing, drilling, grinding and precision instrument equipment.
What are the advantages of CNC machined micro collets?
One-piece CNC machining ensures high concentricity, uniform elastic force and zero deformation, effectively avoiding eccentricity and vibration problems of traditional stamped collets, suitable for high-precision micro working scenarios.
Can you customize special size micro collet chucks?
Yes, we fully customize inner diameter, outer diameter, length, slot structure, stepped shape and special clamping sizes according to customer drawings and samples.
What material is best for micro collet chucks?
High-hardness alloy steel and stainless steel are adopted, featuring wear resistance, fatigue resistance and excellent elasticity, ensuring long-term stable precision clamping performance.
