CNCTOPBAOS K11-65mm CNC 4th Axis
The K11-65mm 4th axis uses a 4:1 reduction belt system and a 63mm chuck, designed for cylindrical work on milling machines and CNC routers. Key components include a 54mm middle height tailstock, a 20mm gear output shaft, and precise centering. The assembly supports three-dimensional processing of cylinders, bends, and circles, expanding capabilities beyond standard two-axis milling. Mounting footprint and compatibility with common CNC platforms make it suitable for hobbyists and professionals pursuing additional rotational capability in a compact form.
CNCTOPBAOS K12-100mm Rotary Table
The K12-100mm rotary table offers a larger working footprint with a 65 mm center height and a 115 mm overall height. It features a 6:1 reduction ratio and a 22 mm through-hole shaft, along with an MT2 tailstock for added axial support. The unit’s aluminum alloy base provides a sturdy yet lightweight platform ideal for CNC engraving and milling where precision and repeatability are essential. Its modular design supports integration with MT2 tooling and standard 8 mm shank components commonly used in hobby and commercial CNC setups.
5th Axis Rotary Axis With Chuck Table
This 5th axis configuration adds a dedicated rotary axis with a chuck table suitable for DIY CNC routers. It includes a 4:1 gear ratio on the primary axis and a 57 two-phase stepper motor, enabling controlled rotation for complex multi-axis operations. The setup is compatible with typical CNC routers and engraving machines, enabling advanced operations on curved surfaces, cylindrical features, and circular contours. When paired with a primary XYZ machine, it broadens the range of possible geometries for parts and prototypes.
11 Pcs CNC Engraver Rotational Kit
This kit features an ER32 hollow-shaft motor arrangement with a complete set of 11 ER32 collets ranging from 3 mm to 20 mm. The hollow shaft design enables flexible integration with various spindle configurations, while the 65 mm center height and 21 mm hollow shaft diameter support compact rotary applications. A 6:1 reduction ratio enhances slow, controlled rotation for engraving and milling tasks, and the NEMA-compatible stepper motor enables straightforward drive compatibility for most 2- to 4-axis CNC systems.
CNCTOPBAOS 3D Edge Finder
The 3D edge finder provides X, Y, and Z axis measurement with a claimed positioning accuracy of up to 0.01 mm. Its sealed aluminum alloy body and tungsten steel ball tip deliver stability during centering and probing, while a full 180-degree probe rotation improves usability without spindle rotation. The tool is designed to boost alignment precision for milling setups and complex multi-axis work, making it a practical addition to a multi-axis CNC workstation.
ACEMETER Z Axis Zero Setter
The Z axis zero setter is a high-precision tool for correcting and setting Z axis on CNC machine tools. It offers a reading resolution of 0.01 mm with a 0-2.5 mm measuring range. Magnetic mounting aids secure positioning, and the aluminum body provides durability. This device is useful for tool height calibration, setup consistency, and rapid height verification, supporting more accurate tool paths and repeatable results in multi-axis milling and drilling workflows.
FOCMKEAS Chucking Reamer 5mm
The 5 mm chucking reamer is a high-speed steel cutting tool designed for precision hole enlargement and deburring in stainless steel and other metals. Its 5 mm shank and 5 mm cutting diameter make it suitable for finishing operations on small-diameter features, chamfering, and producing clean, accurate holes. The tool’s cobalt M35 composition offers a blend of hardness and wear resistance for repetitive machining tasks on CNC mills and lathes.
4 Axis Mach3 Motion Control Card
The Mach3 motion control card provides multi-axis support (up to six axes) for CNC engraving machines, lathes, and plasma cutters. It emphasizes high-speed I/O processing, stable machine communication, and standalone operation to reduce reliance on host PCs. The device supports standard CNC software ecosystems and offers compatibility with a range of servo and stepper motor configurations, enhancing multi-axis synchronization and control with a focus on reliability and safety.
Buying Guide: Key Purchase Considerations for 5 Axis CNC Centers
- Axis configuration and compatibility: Confirm the number of controllable axes, the supported stepper/servo motors, and how the rotary axes integrate with your existing CNC router or mill.
- Load capacity and precision: Assess center height, overall height, chuck size, and centering tolerances. Higher precision and heavier load capacity expand potential part geometries.
- Gear reduction and gearing options: Reduction ratios (e.g., 4:1, 6:1) influence torque, speed, and control resolution. Ensure the drive system matches your spindle and feed rates.
- Tailstock and support: A robust tailstock (MT2/MT3 options) provides axial support for long cylindrical features and helps prevent deflection during long-cut operations.
- Compatibility with tooling: Check ER collets, hollow shafts, and shuttle paths to ensure your existing tooling set fits the adapter and spindle interfaces.
- Mounting footprint and weight: Measure the base dimensions and weight to ensure stable mounting on your machine bed and proper vibration control during heavy cuts.
- Electrical and control integration: Confirm driver, controller, and software compatibility (Mach3, GRBL, LinuxCNC, etc.), as well as power requirements for the axis motors.
- Maintenance and replacement parts: Availability of spare parts such as gears, claws, and tailstock components affects long-term reliability and downtime.
- Use-case versatility: Consider whether you need 4th-axis only, true 5th axis with a separate rotary table, or a modular kit that can evolve with your projects.
In multi-axis CNC workflows, selecting a rotary axis or edge-finding accessory depends on balancing precision, load capacity, and integration with your machine. For hobbyists, compact 4th-axis kits may deliver substantial expansion at a lower upfront cost. For more complex prototypes and production, higher-precision 5th-axis configurations combined with a robust motion controller provide greater capability and repeatable results. Always verify compatibility with your spindle, control software, and toolholding system before purchase.
