Product Overview
R8 Collets from SHANDONG OLI MACHINERY CO., LTD. are engineered to deliver reliable performance in traditional milling operations. Designed for compatibility with R8 taper spindle machines, these collets combine robust construction with cost-effective functionality, making them an ideal choice for educational institutions, repair workshops, and small-scale production facilities.
Technical Specifications
Manufactured from 65Mn steel, R8 Collets feature a hardness range of HRC55–60 in the clamping section and HRC40–45 in the elastic section, ensuring durability and consistent performance. These collets are specifically designed for milling machines with R8 spindle taper holes, such as the X6325 and X5325 models.
Key Features
1. Structural Design and Clamping Mechanism
The 7:24 taper design ensures a precise fit between the collet and the milling machine spindle, providing enhanced rigidity and positioning accuracy. This design is particularly suited for light to medium machining loads.
A drawbar mechanism secures the collet within the spindle taper hole. By applying tension through the drawbar, the collet maintains a tight connection, ensuring stability during operation. While this process requires manual intervention, it offers reliable clamping for various applications.
The spring clamping structure allows the collet to adapt to different tool shank diameters, typically ranging from 1/16" to 3/4". This flexibility makes R8 Collets versatile for holding straight-shank tools such as end mills and drill bits.
2. Application Scope
R8 Collets are primarily compatible with older manual or semi-automatic milling machines, including the Bridgeport series. While they are not designed for modern CNC machining centers, they remain a practical solution for traditional milling tasks.
These collets are ideal for educational settings, maintenance workshops, and low-volume production environments where high-speed or high-precision machining is not a primary requirement.
3. Performance Characteristics
The tapered contact surface provides excellent stability, making R8 Collets suitable for light to medium cutting forces. However, their rigidity is lower compared to modern toolholder systems like BT or CAT.
Manual clamping and tool changes can be time-consuming, which may impact efficiency in high-volume production scenarios. Nevertheless, the simple design and low maintenance costs make R8 Collets a budget-friendly option for users with limited resources.
