High-Precision CNC Machining Center Parts Manufacturing
At Xierge Precision Machinery Co., Ltd., we leverage over 30 years of operational experience since 1990 to engineer high-performance CNC Machining Center Parts for the global power tool and industrial machinery industries. Drive components—such as rotor shafts, armature shafts, drive spindles, and gear shafts—are the core transmission elements of power tools, requiring extreme durability, high torque resistance, and perfect dynamic balance to withstand high-speed rotations and heavy impact loads.
Our state-of-the-art facility is equipped with Japanese imported Star CNC Swiss-type lathes, advanced multi-axis machining centers, and precision grinders. This allows us to machine complex geometries, such as helical gears, spline shafts, and cross-drilled lubrication holes, in a single setup. The Swiss-type guide bushing technology provides unparalleled support, enabling us to produce long, slender drive components with ultra-tight concentricity and straightness, completely eliminating deflection.
Following our core principle of "Integrity Oriented, Quality Foremost," we strictly adopt premium raw materials like 20CrMnTi and 42CrMo alloy steel. To guarantee reliable product performance under heavy-duty conditions, 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.

Core Advantages of Xierge CNC Machining Center Parts
- High-Torque Fatigue Resistance: We strictly select premium alloy steels (20CrMnTi, 42CrMo) designed to withstand the heavy impact loads and high torque generated by industrial power tools.
- Swiss-Type Precision for Shafts: Our Japanese Star CNC Swiss-type lathes excel at machining long, slender rotor and armature shafts, preventing deflection and ensuring exceptional concentricity for high-speed dynamic balance.
- Advanced Heat Treatment Integration: Through controlled induction hardening and carburizing, we achieve a tough core with an ultra-hard, wear-resistant surface (HRC 58+), extending the component's operational lifespan.
- Complex Single-Setup Machining: Our live-tooling capabilities allow us to turn, mill splines, drill cross-holes, and cut threads in a single operation, drastically reducing handling errors and ensuring perfect concentricity.
- Ultra-Precision Grinding: Equipped with advanced cylindrical grinders, we achieve flawless bearing journals and gear tooth profiles (Ra 0.2), reducing friction, heat generation, and noise in the drive assembly.
- Ultrasonic Cleaning Standard: Every drive component goes through dedicated cleaning machines to remove all machining chips and cutting fluids, guaranteeing a spotless surface ready for bearing assembly.
- 3-Decade OEM/ODM Expertise: Since 1990, we have accumulated deep engineering knowledge, allowing us to optimize designs for manufacturability (DFM) and reduce costs for custom power tool projects.
Payment Methods & Global Logistics Solutions
Secure International Payment Terms:
To facilitate smooth B2B international trade, we offer flexible and secure payment options. For mass production orders of CNC Machining Center Parts, we accept standard T/T (Telegraphic Transfer) with a 30% advance deposit and 70% balance before shipment. For large-scale international supply contracts, we are fully capable of processing Irrevocable Letters of Credit (L/C) at sight. For initial prototyping, sample orders, or custom tooling fees, PayPal and Western Union are also available to expedite the process.
Global Logistics & Protective Packaging:
We provide comprehensive end-to-end shipping solutions under FOB, CIF, and DAP Incoterms. For urgent prototypes or small batches, we utilize expedited international couriers such as DHL, FedEx, and UPS. For bulk mass production, we offer highly competitive sea freight (LCL/FCL) and air cargo rates through our trusted global forwarder network. Recognizing that drive components have precise bearing surfaces and threads, we utilize specialized packaging: each shaft is individually wrapped in VCI (Volatile Corrosion Inhibitor) anti-rust paper, secured in custom rigid cardboard tubes or EPE foam slots, and packed in sturdy export-grade wooden cases to prevent any bending or transit damage.
FAQ
Thermal deformation is a major challenge for long drive shafts. We use a two-stage process: rough machining on our Swiss lathes, leaving a specific grinding allowance, followed by induction hardening or carburizing. After heat treatment, we utilize our precision CNC cylindrical grinders to bring the bearing journals and critical diameters back to strict micro-tolerances, effectively correcting any minor thermal warping.
Yes. Our Star CNC Swiss-type lathes and 4-axis machining centers are equipped with live tooling. This allows us to perform hobbing, milling of straight keyways, and cutting of involute splines in a single setup. Because the part is not transferred to secondary machines, we maintain absolute coaxiality between the bearing journals and the splined sections.
For high-speed power tool rotor shafts, dynamic balance is critical. By utilizing the guide bushing support on our Swiss lathes and finishing with precision cylindrical grinding, we can consistently achieve concentricity/coaxiality tolerances within 0.005mm across multiple bearing journals, ensuring smooth, vibration-free operation at high RPMs.
For impact wrenches and heavy-duty power tools, we highly recommend 20CrMnTi or 42CrMo alloy steel. These materials, after carburizing and quenching, provide a hard, wear-resistant surface (HRC 58-62) while maintaining a highly tough core that can absorb sudden impact shock without fracturing.
Trapped chips can destroy bearings and gear mechanisms. After machining and deburring, all drive components pass through our dedicated industrial ultrasonic cleaning machines. This high-frequency agitation combined with specialized flushing fluids removes 100% of micro-burrs and cutting debris from deep cross-holes and blind threads.
Absolutely. Adhering to our "Quality Foremost" principle, we utilize imported Japanese and German testing instruments to conduct SPC (Statistical Process Control). Every shipment is accompanied by detailed dimensional inspection reports, roundness charts, and heat treatment hardness test logs to ensure full traceability and compliance with your specifications.
