SONGRI multi-axis motion control and CNC rotary table kinematics

Shenzhen Songri Intelligent Equipment Co., Ltd. designs precision indexing and rotary motion mechanisms for CNC milling centers. Adding fourth and fifth controlled axes transforms a standard 3-axis milling machine into a versatile multi-axis processing center.

This configuration enables continuous cutting tool access to five sides of a complex workpiece in a single setup.

Songri CNC rotary tables eliminate cumulative positioning errors caused by manual repositioning and significantly reduce cycle times in batch manufacturing.

The rigid structure withstands severe vibration, abrasive chips and high-pressure flood coolant during prolonged continuous metalworking shifts.

SRJ five-axis tilting rotary tables: cross-roller bearings and rigidity

The SONGRI SRJ series encompasses SRJ-125, SRJ-160, SRJ-180, SRJ-210, SRJ-255 and SRJ-320 frame sizes designed for multi-axis simultaneous contouring. Large-diameter cross-roller bearings support both the tilting cradle and faceplate.

Orthogonal cylindrical rollers arranged at ninety degrees absorb thrust, radial and tilting moment forces simultaneously.

A rigid iron housing suppresses mechanical resonance during heavy milling of tool steels and tough titanium alloys. Built-in pneumatic or hydraulic clamping systems lock the rotary axis firmly at required angular positions for accurate finishing passes and heavy roughing cuts.

SRJ-4A fourth-axis rotary indexing tables with zero-backlash RV reducers

For fourth-axis circular indexing and interpolation, SONGRI manufactures SRJ-125-4A, SRJ-170-4A, SRJ-210-4A and SRJ-255-4A models. Precision zero-backlash RV cycloidal gearboxes serve as primary speed reduction mechanisms.

Multiple teeth sharing the contact zone enable the unit to sustain heavy shock loads without plastic deformation.

RV reducers combine high reduction ratios in a compact footprint with high torsional stiffness and negligible lost motion.

This ensures accurate tool path tracking during helical milling, camshaft cutting, spline profiling and multi-sided prismatic component manufacturing on vertical machining centers.

High-speed NC-170 roller gear cam mechanisms for 3C volume production

The NC-170 rotary table series is built around a precision roller gear cam transmission. Unlike worm gear systems that rely on sliding friction, the roller cam mechanism utilizes pure rolling contact between preloaded needle bearing rollers and a globoidal cam rib profile.

This kinematics eliminates backlash, reduces the friction coefficient and avoids mechanical wear over millions of high-speed indexing movements.

The NC-170 series excels in rapid drilling and tapping centers for high-volume manufacturing of smartphone chassis, tablet frames, electronic connectors and precision hardware.

Disk tailstocks, hydraulic brake units and multi-stage seal protection

To support long shafts and extended workpieces, SONGRI manufactures pneumatic and hydraulic disk tailstocks. The large-diameter brake disk is matched to the rotary table holding torque, while an internal spring return piston guarantees prompt release upon hydraulic pressure decompression.

All SONGRI rotary tables and tailstocks feature multi-labyrinth contact seals combined with internal air purge pressurization.

Positive dry air pressure inside the housing prevents ingress of fine metallic dust, abrasive particles and cutting emulsion into bearings, gears and optical angular encoders.

Component selection, technical maintenance and nameplate identification

Engineers match replacement rotary tables, RV cycloidal gears, cross-roller bearings, brake seals, flexible couplings and servo adapters using the original SONGRI equipment nameplate and machine specifications.

Direct dimensional compatibility enables prompt restoration of production machinery without workshop downtime.

Detailed commercial proposals outline technical specifications, international trade documentation and reliable freight forwarding to destination facilities. Every motion unit undergoes dimensional verification, angular accuracy measurement and surface inspection before dispatch.
