Why Choose Us
Precision-Focused Production
Precision grinding and dimensional inspection support the production and verification of tooling components. Product requirements are assessed against the applicable drawings and specifications.
Clear Model Selection
Our selection process considers the spindle interface, ER series, clamping diameter, gauge length, and accessory requirements. Providing these details helps identify a suitable configuration and reduces uncertainty during technical review.
Custom Project Support
For customized orders, drawings, samples, dimensional tolerances, marking requirements, and intended applications can be submitted for review. Technical details are assessed before the project proceeds to quotation and production planning.
Coordinated Export Orders
Order processing covers the confirmed model, quantity, inspection requirements, packaging details, and destination information. These details help align product preparation and shipping arrangements with the purchase order.
Collet Chuck Product Range
ER Collet Chucks
ER collet chucks use a compatible collet and nut to clamp cutting tools with suitable shank diameters. They are used in a range of CNC machining setups, including milling and drilling. Select the ER series according to the required clamping range, tool shank size, and holder dimensions.
NT ER Collet Chucks
NT ER collet chucks are available in specified configurations within the product range. Selection should be based on the exact spindle interface, taper dimensions, gauge length, and compatible accessories. Refer to the relevant model drawing to confirm dimensional requirements before ordering.
Configuration and Accessory Matching
Collets, nuts, and tightening tools should be selected to match the holder system. When requesting a quotation, specify whether the order is for the holder alone or a complete assembly, including the required accessories.
Key Product Features
Consistent Clamping Setup
The holder, collet, nut, and cutting tool work together as a clamping assembly. Correct component matching, clean contact surfaces, and tightening according to the applicable instructions support stable tool retention during machining.
Multiple ER Series
Different ER series provide different nominal clamping ranges. Matching the collet series and bore to the tool shank helps establish the intended fit. The selected holder must also match the machine interface and required working length.
Application-Based Configuration
Gauge length, holder dimensions, operating speed, and cutting conditions affect tool setup. Reviewing these requirements together helps determine whether a particular configuration is suitable for the intended machining operation.

Typical Applications
CNC Milling
Collet chucks can hold compatible end mills for slotting, contouring, shoulder milling, and general component machining. The selected configuration should provide the required tool access and suit the spindle interface and cutting conditions.
Drilling and Holemaking
Compatible shank tools can be held for drilling and related holemaking operations when the tool, collet, and holder specifications are aligned. Tool diameter, working length, and machine requirements should be confirmed during selection.
Mold and Component Machining
Collet chucks are used in tooling setups for mold components, precision mechanical parts, and general engineering work. Selection depends on tool geometry, access requirements, and the dimensions of the machining setup.

Dimensional Verification
Relevant dimensions are checked against the applicable drawing or agreed specifications. Critical dimensions and acceptance tolerances should be identified before production so inspection can follow the confirmed requirements.
Product Inspection
Inspection can address specified dimensions, visible surface condition, product identification, and packaging condition. The inspection scope is determined by the product and the requirements agreed for the order.
Inspection Documentation
If an order requires inspection reports, dimensional records, or defined acceptance criteria, include these requirements in the inquiry. The available documentation and inspection scope should be confirmed before order approval.
Packaging & Shipping
Protective Export Packaging
Packaging is selected according to the product configuration and order requirements. Protective materials and suitable packing methods help preserve tooling surfaces and product identification during handling, storage, and international transport.
Shipping Coordination
Shipping arrangements are based on the confirmed quantity, destination, packaging requirements, and selected shipping method. Provide the delivery address, preferred transport method, and required export documents during order review so the shipping plan can be coordinated with the order schedule.
