Situo Hardware is a professional original manufacturer specializing in tapping machine chuck base assemblies, automatic tapping machine chuck bases, precision tapping machine chuck fixing seats, integrated machine tool fixture combinations and non-standard CNC machined fixture base assemblies. Our products are widely applied in automatic tapping equipment, CNC drilling and tapping machines, multi-head tapping equipment, tooling jigs and precision machine tool fixing systems.
This series of tapping machine chuck base assemblies are core integrated components for tapping equipment, manufactured from high-quality alloy steel and aluminum alloy with CNC turn-mill composite integrated machining technology. Integrating chuck positioning, locking fixation, precision guiding and load-bearing functions, the integrated structure eliminates cumulative errors caused by traditional split assembly.
Featuring compact structure, high rigidity and excellent coaxiality, the assembly fits various standard and non-standard chucks perfectly. It ensures stable clamping without looseness, effectively avoiding chuck offset, tap shaking, thread deviation and tap breakage during tapping processing. Full-parameter non-standard customization is available for base outline, mounting holes, chuck matching aperture, positioning steps and locking structures, suitable for single-head, multi-head, vertical and horizontal automatic tapping equipment to meet high-precision thread processing assembly requirements.
High-strength alloy steel and aviation aluminum alloy are optional with quenching and tempering pretreatment. The materials feature strong deformation resistance, compression resistance and wear resistance, maintaining stable performance under long-term high-frequency tapping operation. Alloy steel fits heavy-duty high-strength working conditions, while aluminum alloy features light weight and good heat dissipation for high-speed precision tapping scenarios.
All structures including base outline, mounting holes, positioning steps, chuck assembly positions and locking grooves are completed in one clamping setup. Strict control of flatness, coaxiality and verticality ensures higher precision than split assembled structures, eliminating jitter and offset problems and guaranteeing consistent thread processing accuracy.
The integrated design combines base fixing, chuck positioning and limit locking functions, enabling direct installation without complicated assembly. Built-in limit structure prevents chuck rotation, offset and axial movement, ensuring stable clamping force during forward and reverse tapping, reducing tap breakage and defective thread rate, and supporting long-term continuous mass production.
Compatible with vertical, horizontal, multi-head, full-automatic and semi-automatic drilling and tapping equipment, matching ER chucks, spring chucks and quick-change chucks. Customizable base size, hole spacing, matching aperture, step height and locking structure. Special structures such as through holes, counter holes and positioning pin holes are available. Customization based on drawings and samples supports new equipment assembly and old equipment renovation.
Precision grinding and edge chamfering remove all burrs for smooth surface. Carbon steel versions adopt blackening, galvanizing and hard chrome plating for wear resistance and oxidation resistance; aluminum alloy versions adopt hard anodizing treatment for scratch and corrosion resistance, adapting to complex industrial environments with oil and moisture.
Complete quality control procedures include raw material verification, blank screening, first-piece inspection, geometric tolerance full inspection, hole gauge testing and appearance trimming. Key dimensions are precisely measured to ensure high batch interchangeability, meeting high-end assembly and mass production standards for automation equipment and precision machine tools.
We specialize in non-standard customization of tapping machine chuck base assemblies. Complete production workflow: material cutting & tempering → CNC turn-mill integrated machining → precision hole processing → limit & locking structure forming → deburring & chamfering → hardening & anti-rust treatment → full precision inspection → finished product delivery.
Sampling lead time is 3-5 days. Small and large batch orders are acceptable. Material certificates and dimension inspection reports can be provided with export-grade packaging. We optimize product structure and technology according to equipment model, processing load, precision requirements and installation space, providing one-stop custom solutions for all types of tapping machine chuck bases.
