Rotarycraft provides specialized guidance, design insights, and technical support for clients working with advanced fabrication and high-speed rotating assemblies. From spindle retrofits to custom calibration rigs, we help turn complex mechanical challenges into reliable solutions.
Explore our capabilitiesHigh-Speed Spindle Retrofit — Complete redesign of a CNC spindle assembly achieving 40% higher RPM with 25% less thermal drift.
Practical support for precision rotating systems, from design validation to production-ready solutions.
Bearing selection, shaft dynamics, and thermal analysis for high-speed assemblies.
Modular clamping systems for complex geometries and thin-walled parts.
Custom test rigs and measurement procedures for rotary accuracy.
Whether it's a spindle retrofit or a custom fixture, we help you move from concept to precision fabrication.
Start a project discussionEvery project we support is built on measurable outcomes — tighter tolerances, shorter lead times, and fewer iterations.
Closed-loop cooling and ceramic hybrid bearings cut thermal displacement by 25% in high-RPM spindles. Your toolpath stays accurate run after run.
Automated data acquisition and air-bearing fixtures reduce angular verification time by 60%. You get repeatable results within 2 arc-seconds.
Hydraulic clamping with custom inserts cuts changeover time by 70% across varying blade geometries. First-pass yield improves by 15%.
Every clamping and spindle assembly is simulated before fabrication. We catch distortion and resonance issues before metal is cut.
Hybrid bearing preload and dynamic balancing keep spindle speed variation below 0.5% under load. Surface finish improves consistently.
Calibration rigs and fixture systems are designed to drop into existing quality workflows. No retraining or custom software required.
We work on a wide range of rotating and fabrication systems, including spindle retrofits, rotary indexer calibration, turbine blade fixtures, and custom workholding solutions. Our focus is on mechanical craftsmanship and advanced fabrication.
Yes. We offer preliminary design reviews and technical guidance during the planning phase. This helps identify potential issues early and ensures the final solution meets your performance requirements.
Timelines vary based on complexity. A spindle retrofit might take 6–10 weeks from analysis to installation, while a modular fixture system could take 8–12 weeks including testing. We provide a detailed schedule during the proposal stage.
Both. We can refine your existing design for manufacturability or develop a completely new solution based on your specifications. Our team handles FEA analysis, material selection, and fabrication drawings as needed.
We use calibrated measurement equipment, perform in-process inspections, and validate final assemblies against your tolerance requirements. For rotating systems, we test for vibration, thermal stability, and angular accuracy before delivery.
