For manufacturers processing long oil tubes and heavy-wall pipe materials, maintaining stable clamping and machining accuracy is a consistent challenge. In a recent application, MYDAY Machinery integrated AUTOGRIP’s AP-375 large thru-hole air chuck on its CNC precision oil-tube lathe to address these requirements. The combination delivers a high-stability workholding system designed specifically for long-pipe turning and deep-hole machining environments.

High-Stability Workholding for Long Oil Tubes

The machining setup adopts a dual-chuck configuration, positioning the AP-375 at the front spindle while a secondary chuck supports the rear. This arrangement ensures the entire length of the oil tube remains securely clamped as the material feeds from the back of the machine. A hydraulic steady rest is installed at the tail end to stabilize extended sections of the tube, enabling smooth, vibration-free turning of long or heavy components.

This system is particularly effective for oil-and-gas pipe machining, long hydraulic tubes, drilling pipes, and other extended bar materials that demand rigid support throughout the process.

Key Features of the AUTOGRIP AP-375 Air Chuck

1. Large Thru-Hole Pneumatic Chuck Structure

The AP-375 integrates a built-in pneumatic actuator to deliver consistent clamping force.
Its large thru-hole design supports long tubes, hollow bars, or solid materials that must pass entirely through the spindle—making it ideal for oil tube machining applications.

2. Built-In Pressure Monitoring for Safe Operation

The chuck incorporates an internal pressure-sensing mechanism that automatically detects abnormal pressure drops.
This protects against unexpected workpiece loosening and enhances operational safety during continuous cutting.

3. AUTOGRIP’s Patented Air-Supply System

AUTOGRIP’s patented design removes the need for traditional sealing rings, reducing installation complexity and preventing seal-ring wear or failure.
This structure lowers long-term maintenance costs and minimizes machine downtime—key factors in high-volume tube manufacturing lines.

4. Compatible with C-Axis Machining Requirements

When paired with the lathe’s C-axis positioning, the AP-375 ensures precise chuck alignment and repeatable clamping accuracy, supporting advanced turning processes or secondary machining operations.

Measurable Benefits for MYDAY’s Oil Tube Machining

By implementing the AP-375 dual-chuck system with steady-rest support, MYDAY Machinery achieved notable improvements:

• Higher machining efficiency, with reduced manual repositioning

– Greater process stability during long-duration cutting

• Improved operator safety due to pressure-monitoring protection
• Consistent accuracy for long tubes and heavy-duty pipe turning

The integration demonstrates how AUTOGRIP’s advanced workholding technologies can significantly enhance CNC lathe performance in oil-tube and long-pipe production lines.

Patented Liquid Fermentation Technology Delivers Stable Erinacine A Content with Full International Certifications – Positioning for Strong Entry into the North American Neurohealth Market

New Bellus Enterprises Co., Ltd. (www.newbellus.com) proudly announces that its Hericium erinaceus mycelia raw material has officially successfully completed the U.S. Food and Drug Administration (FDA) New Dietary Ingredient (NDI) notification process. The FDA has acknowledged receipt and filed the submission under NDI No. 1422 without raising any safety objections, fully complying with U.S. regulatory requirements for market entry.

This milestone makes New Bellus the world’s first company to obtain FDA NDI acknowledgment for Hericium erinaceus mycelia, representing international recognition of its technological strength and marking the official launch of its strategic expansion into the North American market.

Hericium erinaceus (Lion’s Mane mushroom) has long been regarded in Asia as a precious tonic mushroom. In recent years, scientific research has demonstrated its potential in neuroprotection, cognitive function improvement, and delaying neurodegeneration, rapidly gaining attention in the European and North American dietary supplement industries. Previously, the lack of sufficient safety data in the U.S. market restricted commercial development. The successful completion of the FDA NDI process confirms the safety profile of this ingredient, allowing legal sales in the United States and laying a solid foundation for future product development across North America and Europe.

New Bellus’ R&D team emphasizes that the company has focused over 30 years on microbial fermentation technology. By employing its patented deep-tank liquid fermentation technology, the company achieves stable production of the key bioactive compound Erinacine A as well as polysaccharides. This advanced method enables scalable, sustainable mass production while overcoming the quality and yield limitations of traditional solid-state cultivation. The product has already earned multiple international quality certifications, including FSSC 22000, HACCP, NSF GMP, ISO 17025, and HALAL, ensuring safety, consistency, and global market acceptance.

Erinacine A, the signature bioactive compound found exclusively in liquid-fermented Hericium erinaceus mycelia (not present in wild or solid-cultivated fruiting bodies), has been shown in numerous peer-reviewed international studies to promote the expression of nerve growth factor (NGF). It supports neurological health, learning and memory function, and helps modulate neuroinflammatory responses, providing strong scientific evidence for its role in delaying neurodegeneration and promoting healthy aging.

Looking ahead, New Bellus remains committed to advancing functional fermentation technology. The company will continue to strengthen R&D capabilities and drive innovative applications of probiotics powder, mushroom mycelium powder, and other natural medicinal fermented powder, with a particular focus on cognitive health and nutritional support for middle-aged and elderly populations. In response to the global aging trend, New Bellus will uphold evidence-based science, sustainable manufacturing processes, and international partnerships as core principles to deliver safer, higher-value natural health solutions that enhance quality of life and human well-being worldwide.

About New Bellus Enterprises Co., Ltd. With over three decades of expertise in microbial fermentation services, New Bellus specializes patented liquid fermentation technology to develop high-potency, science-backed functional ingredients for the global nutraceutical and dietary supplement industries.
