High-Accuracy Ball Screws & Lead Screw Shafts

At XML Tech, we manufacture custom, high-accuracy ball screws and lead screw shafts engineered to convert rotational movement into flawless, linear positioning under high mechanical loads. Linear motion transmission demands extreme geometric compliance; even a micro-level deviation in thread pitch or coaxiality can lead to severe mechanical backlash, position drifting, and premature component wear.

Utilizing advanced multi-axis CNC whirling, thread-milling, and high-precision cylindrical grinding machinery, our facility processes both high-efficiency ball screws (for low friction and high-speed inputs) and robust lead screws (for high static load capacity and self-locking requirements). We serve global OEM brands in CNC automation, robotics, medical devices, and aerospace hardware components.

Technical Capabilities & Specifications:

• Microscopic Tolerance Control: We regularly lock in linear and dimensional tolerances as tight as $\pm0.005\text{mm}$ on thread profiles, ensuring repeatable positioning accuracy and eliminating mechanical backlash.

• Precision Thread Whirling & Milling: Our multi-axis CNC machines utilize high-speed thread whirling to cut precise, deep screw tracks in a single setup, guaranteeing flawless lead consistency and extreme concentricity.

• Advanced Materials & Hardening: Sourced from certified gear alloys, high-carbon steels, or wear-resistant stainless steel (SUS304/316L). We provide specialized in-house induction hardening and nitriding to optimize surface hardness for long-term smooth operation.

• Ultra-Smooth Surface Finishes: Multi-stage internal and external thread grinding processes achieve superior surface finishes down to $Ra\ 0.4$, significantly minimizing friction coefficients and expanding screw service life.

Why Partner with XML Tech?

• Direct-to-Factory B2B Pricing: As an all-encompassing, direct hardware contract manufacturer, we eliminate sourcing brokers and trading company markups to deliver transparent, factory-direct quotes.

• Flexible Batch Control: Equipped with modular workholding fixtures, we easily handle low-volume flexible prototyping runs (1-50 pieces) for R&D validation, as well as automated, large-scale mass manufacturing campaigns.

• Engineering-Driven DFM Support: Submit your .STEP, .STP, or .PDF drawings. Our technical department conducts a comprehensive Design for Manufacturing (DFM) analysis to streamline cycle times and reduce your per-unit purchasing costs.
