Kunshan Meiyaxing Hardware Machinery Co., Ltd. is a service-oriented enterprise specializing in the sales and operation of CNC cutting tools. We provide tungsten carbide end mills, end mill inserts, turning inserts, grooving and parting inserts, drilling and boring inserts, multi-functional inserts, threading inserts, and other indexable inserts, along with matching tool holders and tool holders. We have established long-term and stable strategic partnerships with well-known professional manufacturers of high-efficiency tungsten carbide end mills. Our company possesses advanced production equipment from Swiss ROLLOMATIC, German WALTER, and Japanese MAKINO SEIKI, as well as testing equipment from German ZOLLER-GENIUS 3S and American PG 1000. Based on our service and operations, combined with strong R&D and production capabilities, we solve various tooling problems for machining and manufacturing enterprises. We aim to become a professional partner integrating "total tooling solutions and cost optimization services," striving to optimize product processing costs and achieve a mutually beneficial and common development.
I. When are non-standard chucks needed?
The demand for customized non-standard chucks typically stems from the following typical scenarios:
1. 1. Clamping Requirements for Irregularly Shaped Workpieces
When the workpiece cross-section is a square hole, hexagonal hole, irregularly shaped hole, stepped hole, or eccentric hole, standard round hole chucks cannot effectively clamp it. For example, irregularly shaped workpieces such as shafts with helical blades or multi-faceted workpieces must rely on custom-made fixtures to ensure clamping contact area and stability.
2. Size Requirements Exceeding Standard Series
Standard ER chucks (such as ER16, ER20, ER25, ER32, etc.) have a fixed clamping range. When clamping non-standard diameters (such as ER32 clamping 24mm, 25mm, etc., non-standard sizes), custom-made non-standard chucks are necessary.
3. High Precision and High Stability Requirements
In precision machining, the runout accuracy of standard chucks (typically 0.01mm) may not meet requirements. Non-standard chucks can achieve AA-level accuracy (0.005mm), significantly improving surface finish and reducing machining noise and tool vibration.
4. Special Clamping Methods
· Internal Hole Tension Clamping: Suitable for applications where the workpiece's internal hole serves as the positioning reference. Rubber elastic chucks (tension sleeves) excel in such scenarios, offering a clamping range of ±0.5mm and rotational accuracy ≤0.01mm.
• Blind Hole Clamping: Some elastic chucks are specifically designed for blind holes, enabling clamping from below via pneumatic or hydraulic systems.
II. Selection and Customization Considerations for Non-Standard Chucks
1. Define Workpiece Parameters
Before customization, the following information is required: workpiece material, shape and dimensions of the clamping area, machining accuracy requirements (runout tolerance), and cutting parameters (speed, feed rate).
2. Select Appropriate Materials and Processes
• Spring Steel (e.g., 65Mn): After heat treatment, it offers good elasticity and a long service life, suitable for conventional clamping applications.
• Tungsten Carbide Internal Hole: Utilizing ultrafine tungsten carbide from Taiwan, it possesses excellent wear resistance and high-temperature resistance, suitable for heavy cutting or difficult-to-machine materials.
• Rubber vulcanization process: The rubber elastic chuck is bonded with high-polymer materials, making it waterproof and chip-proof, with a service life of 150,000 to 300,000 cycles.
3. Confirm the installation interface type
Non-standard chucks must be compatible with the machine tool spindle or tool holder. Common compatible brands include Nomura, Tsugami, Citizen, STAR, and TORNOS Swiss
