Let’s delve into the world of aluminum profiles and linear rail extrusions for CNC machines and 3D printers.

The T-slot and V-slot aluminum profiles you’ve mentioned are commonly used in various applications, including building frames, machinery, and DIY projects. Here’s a breakdown of what each part of your query refers to:

1. T-Slot Aluminum Profile:

   • T-slot profiles have a distinctive T-shaped groove along their length, allowing you to easily attach accessories, brackets, and other components.
   • The numbers (e.g., 2020, 2040, 2060, etc.) represent the profile dimensions. For instance:
     • 2020: 20mm x 20mm cross-section.
     • 2040: 20mm x 40mm cross-section.
     • 2060: 20mm x 60mm cross-section.
   • These profiles are versatile and can be used for constructing frames, enclosures, and workbenches.

2. V-Slot Aluminum Profile:

   • V-slot profiles have a V-shaped groove, which provides additional rigidity and allows for smooth linear motion.
   • They are often used for building linear motion systems, such as CNC routers, 3D printers, and camera sliders.
   • The numbers (e.g., 3030, 3060, 4040, etc.) indicate the profile dimensions, similar to the T-slot profiles.

3. Linear Rail Extrusion:

   • Linear rail extrusions are precisely machined aluminum profiles designed for linear motion applications.
   • They provide a stable guide for moving components (such as printer heads or CNC toolheads) along a straight path.
   • The specified lengths (e.g., 200mm and 500mm) refer to the extrusion’s overall size.

4. CNC 3D Printer Parts:

   • These aluminum profiles are essential components in CNC machines and 3D printers.
   • They serve as the framework for assembling the machine, ensuring stability and accurate movement.

If you’re interested in custom-cut aluminum extrusions, some suppliers offer services where you can specify the desired length in millimeters. Keep in mind that there are tolerances for length and angle, so precision matters when ordering pre-cut pieces. Whether you’re building a CNC machine or upgrading your 3D printer, these profiles play a crucial role in creating a robust and functional system.
