Prolinemax Precision MT5 Bull Nose Live Center 75° 0.0007″ TIR 5MT

Description

Product Overview

The Prolinemax Precision MT5 Bull Nose Live Center is engineered for the most demanding machining environments, offering a combination of high‑precision geometry and rugged construction. Its 75 degree tapered bull nose design provides a smooth transition from the point to the shank, reducing stress concentrations and extending tool life. The point diameter of 1.37 inches and a point length of 3.46 inches deliver a substantial contact area, while the total indicated runout (TIR) of just 0.0007 inches ensures that every cut is performed with exceptional accuracy. Constructed from high‑grade steel and heat‑treated to achieve a hardness that resists wear, this live center can sustain a maximum load capacity of 1,760 pounds, making it suitable for heavy‑duty turning operations.

Designed to fit a Morse Taper MT5 socket, the live center integrates seamlessly with standard lathe tool posts and CNC spindle assemblies. Its outside diameter of 6.29 inches provides a stable bearing surface, and the bull nose bottom diameter of 160 mm (approximately 6.30 inches) offers additional rigidity when engaged with workpieces. The center is capable of operating at speeds up to 1,600 RPM, delivering consistent performance across a wide range of materials, from soft aluminum to hardened steel. The overall dimensions of 6‑1/4″ L × 6‑1/4″ W × 10″ H make it compact enough for tight machine setups while still delivering the mass needed for vibration damping.

Every component of the Prolinemax live center is manufactured to tight tolerances, and the product undergoes a rigorous quality inspection process before shipment. The result is a tool that not only meets but exceeds industry standards for live centers, providing machinists with confidence that their turning operations will be both precise and repeatable. Whether you are a professional CNC operator or a hobbyist machinist, the Prolinemax MT5 Bull Nose Live Center offers the reliability and performance required to achieve superior surface finishes and dimensional accuracy.

Usage

This live center excels in a variety of machining scenarios. In CNC turning applications, it serves as a reliable support point for long, slender workpieces, reducing deflection and improving concentricity. Its high load capacity allows it to handle large diameter blanks without compromising stability, making it ideal for automotive and aerospace component production where precision is critical. For manual lathe users, the bull nose geometry simplifies setup by providing a self‑centering point that quickly aligns with the workpiece, reducing setup time and minimizing the risk of misalignment.

Beyond traditional turning, the Prolinemax live center can be employed in specialized processes such as tube bending, mandrel turning, and even as a reference point for coordinate measuring machines (CMM) when high repeatability is required. Its ability to maintain a TIR of 0.0007 inches ensures that even the most delicate operations, such as micro‑machining or finishing of intricate contours, are performed with the utmost fidelity. The tool’s compatibility with standard MT5 chucks also means it can be easily swapped between machines, providing flexibility for shops that operate multiple lathe models.

FAQ

What size workpieces can the Prolinemax live center accommodate?

The live center is designed to support workpieces up to a maximum diameter of approximately 6.29 inches (outside diameter) and a minimum diameter of about 1.37 inches at the point. This range covers most turning applications, from small precision components to larger shafts used in automotive and aerospace industries.

Can the live center be used on both CNC and manual lathes?

Yes. The Prolinemax live center features a standard MT5 Morse taper, which is compatible with the spindle noses of most CNC and manual lathes. Its bull nose geometry simplifies alignment on manual machines, while the precise TIR and high RPM rating make it an excellent choice for high‑speed CNC turning operations.

How does the 0.0007″ TIR improve machining results?

A total indicated runout of 0.0007 inches means the point of the live center deviates very little from true concentricity. This tight tolerance reduces vibration and chatter during cutting, leading to smoother surface finishes, tighter dimensional tolerances, and longer tool life because the cutting forces are more evenly distributed.

What maintenance is required to keep the live center performing optimally?

Regular cleaning of the bearing surfaces and periodic lubrication with high‑temperature spindle oil are recommended. Inspect the point for wear after extended use, and replace the point if it becomes rounded or damaged. Following these simple maintenance steps will ensure consistent performance and extend the service life of the live center.

Is there a warranty or support program for this product?

Prolinemax offers a one‑year limited warranty covering manufacturing defects. In addition, our technical support team is available to assist with installation, troubleshooting, and optimization advice. We also provide a parts replacement program to quickly address any wear‑related concerns, minimizing downtime for your shop.
