Introduction

Titanium alloy parts represent the pinnacle of high-performance manufacturing, standing at the intersection of advanced materials science and precision engineering. At Xierge Precision, we specialize in transforming this demanding material into highly accurate, application-ready components that meet the strict requirements of modern high-end industries. Titanium alloys are widely recognized for their exceptional combination of properties, but their machinability presents significant challenges that require deep technical expertise and carefully controlled production processes.

One of the primary difficulties in titanium machining is its poor thermal conductivity. During cutting, heat tends to concentrate at the tool edge rather than dissipating through the workpiece, leading to rapid tool wear and potential deformation of both tool and material. In addition, titanium’s high chemical reactivity at elevated temperatures can accelerate tool degradation, making conventional machining strategies ineffective. At Xierge Precision, we address these issues through rigid machine setups that maximize stability and minimize vibration, ensuring consistent cutting performance even under demanding conditions.

Another challenge lies in titanium’s inherent elasticity and strength. Unlike more brittle metals, titanium tends to spring back during machining, which can affect dimensional accuracy and surface finish. To overcome this, we employ optimized cutting parameters, including carefully selected feed rates, spindle speeds, and tool geometries tailored specifically for titanium alloys. Our engineering team continuously refines these parameters based on real-time feedback and accumulated process data, allowing us to maintain tight tolerances and superior surface quality across complex geometries.

Cooling strategy is also a critical factor in titanium machining. Because of the heat concentration during cutting, effective cooling is essential to extend tool life and maintain part integrity. At Xierge Precision, we utilize advanced cooling techniques, including high-pressure coolant delivery systems that directly target the cutting zone. This not only reduces thermal buildup but also improves chip evacuation, preventing re-cutting of chips and further enhancing machining stability. In some cases, we also integrate specialized lubricants designed for high-temperature alloy processing to further improve efficiency.

Titanium alloys are highly valued in industries where performance, reliability, and safety are non-negotiable. One of the most prominent application areas is the aerospace sector, where titanium is used in structural components, engine parts, and fasteners due to its outstanding strength-to-weight ratio. Titanium offers the strength of steel at nearly half the weight, making it an ideal material for reducing aircraft weight while maintaining structural integrity and fuel efficiency. This advantage directly contributes to improved performance, longer range, and reduced operational costs for aerospace systems.

In the medical field, titanium’s excellent biocompatibility makes it a preferred material for implants, surgical instruments, and prosthetic devices. It is non-toxic, corrosion-resistant, and capable of integrating well with human bone tissue, which is essential for long-term implantation success. At Xierge Precision, we produce medical-grade titanium components that meet stringent regulatory and quality standards, ensuring both safety and reliability for critical healthcare applications.

Beyond aerospace and medical engineering, titanium alloys are also increasingly used in high-performance automotive, marine, and chemical processing industries, where durability and resistance to extreme environments are required. Xierge Precision supports these sectors by delivering custom-machined titanium solutions tailored to specific engineering requirements, whether for prototyping, small-batch production, or large-scale manufacturing.

Through a combination of advanced machining technology, process optimization, and strict quality control, Xierge Precision continues to push the boundaries of what is possible with titanium alloy parts. Our commitment to precision and innovation ensures that every component we produce meets the highest standards of performance, reliability, and consistency, reinforcing titanium’s role as a truly premium engineering material in modern manufacturing.

High-Precision Swiss-Type CNC Turned Parts (Star CNC) for Advanced Mechanisms

At Xierge Precision Machinery Co., Ltd., we leverage over 30 years of operational experience since 1990 to manufacture premium Swiss-Type CNC Turned Parts (Star CNC) for the automotive, medical, and industrial machinery sectors. Small module gears are critical for high-ratio, compact drive systems—such as micro-motors, robotic joints, and precision medical pumps—requiring exceptional tooth profile accuracy, minimal backlash, and superior surface finish to ensure smooth, quiet transmission and high fatigue resistance.

Our production facility is equipped with Japanese imported Star CNC Swiss-type lathes, advanced 4-axis CNC machining centers, and precision grinders. This allows us to machine complex gear geometries, including spur gears, helical gears, and bevel gears, with micro-level tolerances. The Swiss-type machining capability enables us to integrate gear hobbing and milling processes directly onto long, slender shafts in a single setup, guaranteeing extreme concentricity between the gear pitch circle and the bearing journals.

Following our core principle of "Integrity Oriented, Quality Foremost," we exclusively adopt premium raw materials, such as 20CrMnTi, SUS303/304, and brass, tailored to your specific torque and environmental requirements. We apply strict quality inspection protocols utilizing a complete set of testing instruments imported directly from Japan and Germany. We keep innovating to maintain sound business development, and we warmly welcome domestic and overseas clients to visit our factory and explore custom OEM/ODM cooperation opportunities.

FAQ

1. How do you verify the tooth profile and pitch accuracy of small module gears?

Micro-precision gears require advanced metrology. We utilize imported German and Japanese gear measuring machines (GMM) to conduct comprehensive inspections. These instruments map the actual tooth flank topography, measuring involute profile deviation, helix deviation, and cumulative pitch deviation, ensuring they meet strict ISO Grade 6-8 or AGMA Q10+ standards.

2. Can you manufacture small module gears integrated directly onto long shafts?

Yes. This is one of our core specialties. Our Japanese Star CNC Swiss-type lathes, equipped with live tooling and hobbing attachments, allow us to cut gear teeth directly onto long, slender shafts in a single setup. This eliminates secondary clamping errors, ensuring perfect concentricity between the gear pitch circle and the bearing journals.

3. How do you address thermal deformation when heat-treating small module carburized gears?

Small module gears are highly susceptible to thermal warping. We mitigate this by leaving a precise grinding allowance before heat treatment. After carburizing and quenching, we use specialized fixtures and CNC gear grinding machines to correct any micro-deformation, restoring the exact tooth profile and achieving the required surface finish (Ra 0.4).

4. What materials do you recommend for low-noise, high-speed medical pump gears?

For medical applications requiring quiet operation and corrosion resistance, we highly recommend SUS303 or SUS304 stainless steel, or POM (Delrin) for plastic gears. For higher torque requirements, we can use brass (C36000) which offers excellent machinability and inherent anti-galling properties.

5. What is the minimum module size you can reliably machine?

With our precision Swiss-type lathes and micro-machining centers, we can reliably machine spur and helical gears with modules as small as 0.2M. We utilize specialized micro-hobbing cutters and optimized cutting parameters to prevent tooth chipping and ensure smooth meshing for micro-mechanisms.

6. Do you offer QPQ (Salt Bath Nitrocarburizing) for small module gears?

Absolutely. QPQ is an excellent surface treatment for small module gears, particularly those made of carbon steel. It significantly increases surface hardness and wear resistance while improving corrosion protection, all with minimal thermal distortion compared to traditional quenching, which is ideal for preserving tight gear tolerances.
