MuChaIOAK Boring Cylinder Machine Accessories

The MuChaIOAK boring cylinder machine accessory is built from No. 45 steel, delivering high strength and resistance to deformation. Its durable construction supports automatic feeding face milling when boring and aims for a longer service life. The smooth iron surface minimizes dust buildup, simplifying cleaning between jobs. Key dimensions include an inner hole diameter of 50 mm (1.97 in) or 40 mm (1.57 in), with a processing diameter range of 55–300 mm (2.17–11.81 in). Product size is approximately 21×7×3 cm (8.26×2.76×1.18 in) and weighs around 5 kg (11.02 lb).
CNCTOPBAOS K12-100mm 4th Axis Rotary Table

The CNCTOPBAOS 4th axis rotary table combines a 100 mm work diameter with MT2 tailstock support. It features a 6:1 reduction ratio, a Nema23 hybrid stepper motor, and a 0.3° per step resolution, enabling precise rotation for complex milling operations. The unit includes a tailstock with a Morse Taper 2 live center, stroke expansion of 45 mm, and a 50 mm travel. Overall dimensions are 210×168×115 mm with an approximate weight of 7.9 kg, making it a solid option for enlarging a milling setup’s capabilities.
CRYBY Boring Cylinder Machine Accessory 50mm

CRYBY’s boring cylinder accessory uses a high-quality 45 gauge steel construction designed for automatic feed face milling during boring. It emphasizes a close fit with original parts and offers a smooth, well-made surface to ensure safe replacement. Its 50 mm inner hole is compatible with standard tooling, and the component is designed for easy integration into existing boring setups, contributing to efficient, repeatable milling cycles.
kitneed 50mm Boring Facing Head

The kitneed 50mm boring facing head is crafted from No. 45 steel for high strength and deformation resistance. It offers easy replacement by removing the original parts and swapping in the new head, saving time and effort. The smooth surface finish supports safe handling and installation, while the device’s 50 mm interface matches standard boring machine configurations for straightforward integration into existing workflows.
VEVOR 4 Inch ACCU Lock Down Vise

The VEVOR Accu Lock Down Vise is designed for precise milling and drilling work. It features a robust, high-hardness structure and a smooth jaw movement for minimal vibration during clamping. With a 4-inch jaw width and 4-inch opening, it provides reliable clamping force and accuracy, helping to secure cylinder head components during milling, surfacing, and finishing tasks. The vise contributes to repeatable setups and reduces workpiece shift during machining.
Buying Guide: Cylinder Head Milling Tool Considerations
- Material quality and tool rigidity: Durable steels (like No. 45) reduce deformation and extend service life for boring and facing heads used in head milling work.
- Compatibility with existing equipment: Ensure bore diameters, inner hole sizes, and tailstock interfaces fit your machines, whether converting to a 4th axis or using a fixed vise.
- Precision and repeatability: Look for tools with tight tolerances and precise adjustment capabilities, such as 0.002″ parallelism/squareness in vises or fine stepper-driven rotation in rotary tables.
- Ease of replacement and maintenance: Parts that install quickly without complex steps save downtime and support consistent production.
- Clamping stability: A secure vise or clamping system minimizes workpiece movement, improving surface finish and dimensional accuracy during milling.
- Versatility and accessory ecosystem: Tools offering multiple hole sizes, heads, or tailstock options allow a broader range of cylinder head milling tasks without buying multiple standalone units.
- Safety and ergonomics: Smooth surfaces, proper shielding, and manageable weight help workers operate tools safely and efficiently.
