CNC Machine Tools and Lathes HONGGANG CNC / Chongqing Honggang

We deliver advanced CNC lathes, automated production lines and precision components from HONGGANG CNC manufactured by Chongqing Honggang CNC Machine Tool Co. Complete engineering selection by machine nameplate, factory quality compliance and international export logistics.

Precision CNC Lathes IS Series

The flagship line of HONGGANG IS series precision CNC lathes is engineered for high-accuracy machining of complex parts. The rigid monolithic slant-bed angled at 30 degrees and precision spindle bearing sets guarantee exceptional surface finish and positioning stability.

Solid 30-degree slant bed made of HT300 gray iron with full thermal stress relief
Four-layer labyrinth waterproof seal protecting spindle bearings from cutting fluid
Spindle support featuring four front and two rear matched precision bearings
Flexible platform supporting live tooling turrets, Y-axis and synchronized sub-spindle

Horizontal Slant-Bed Lathes HG Series

Universal CNC turning centers of the HG series are designed for highly productive metal turning and heavy-duty cutting operations. Engineered thermal equilibrium and rigid box slideways ensure consistent dimensional precision during long production runs.

Advanced spindle headstock featuring heat-dissipating ribs for thermal balance
Bi-directional pre-tensioning of ground ball screws along both X and Z linear axes
Heavy-duty rectangular guide tracks providing rigid support for tailstock
Modular platform compatible with 12-station servo turrets and steady rests

Engine Valve Dedicated CNC Machines

Specialized turning machines by HONGGANG are developed for high-speed contour processing of internal combustion engine valves. The dedicated machine layout performs valve stem turning, head facing, locking groove profiling and seat angle cutting in a single clamping.

Purpose-built tooling layout for turning valve outer diameter, taper and radiuses
Seamless integration with pneumatic feeders and multi-joint gantry robotic arms
Ultra-precise pneumatic collet clamping ensuring workpiece runout within two microns
Fast cycle times delivering fully turned engine valves in four to seven seconds

Crankshaft and Flywheel Machining Centers

Dedicated machine tools from HONGGANG designed for machining critical engine crankshaft and flywheel components. Configured with heavy-duty servo turrets and eccentric indexing chucks, these units machine crankpins, flywheel mounting faces and bolt patterns accurately.

Rigid 45-degree slant bed design facilitating free chip fall and heavy-duty stock removal
Hydraulic chucks with indexing eccentric mechanisms for crankpin turning
High-torque live tool turret performing precision drilling, tapping and slot milling
Programmable steady rests stabilizing slender multi-cylinder crankshafts

Combined Turn-Grind and Double-End Lathes

Multi-functional CNC solutions combining hard turning and high-speed grinding in one setup, as well as simultaneous double-ended axle turning. These specialized machines eliminate re-clamping runout errors and ensure strict coaxial tolerance between opposite bearing journals.

Seven-axis CNC system managing dual main spindles, slides X1/X2, Z1/Z2 and grinding unit
High-velocity grinding spindle assembly achieving wheel speeds up to 120 m/s
Double-ended horizontal turning layout with dual-channel CNC for simultaneous profiling
Dual-spindle architecture with fixed and movable spindles accommodating varying lengths

Spindle Units, Guideways and Motion Drives

Complete assembly units and mechanical spare parts for HONGGANG CNC and Chongqing Honggang machine tools. We supply cartridge spindle units, servomotors, ground linear slideways, tool indexing turrets and hydraulic chucking cylinders matched to manufacturer technical specifications.

Balanced cartridge spindle units equipped with matched high-speed bearing sets
Precision ground ball screws for X and Z linear axes with double preloaded nuts
Twelve-station servo-driven BMT and VDI tool turrets with hydraulic coupling locks
High-pressure hydraulic clamping chucks, hollow rotary cylinders and control blocks

Technical Inspection and Diagnostics of HONGGANG CNC Lathes

Comprehensive on-site technical inspection of HONGGANG CNC and Chongqing Honggang machine tools is conducted by qualified service engineers.

Diagnostic procedures include precision spindle runout testing, bearing vibration analysis, box slideway alignment verification and laser measurement of ball screw backlash along X and Z axes.

Based on metric measurements, an official technical inspection report is prepared outlining component wear rates, baseline alignment deviations and restorative maintenance recommendations to restore specified factory performance.

Preventive Maintenance Regimes and Scheduled Lubrication Cycles

Scheduled preventive maintenance for HONGGANG CNC lathes follows standardized manufacturer protocols tailored to machine operating hours. Regimes encompass flushing of automated oil distribution manifolds, hydraulic pressure stabilization, coolant filter renewal and drive belt tension adjustment.

Technical specialists inspect telescopic slideway wipers, adjust taper gibs and verify inductive limit switches to prevent unexpected downtime and maintain repeatable positioning.

Overhaul of High-Speed Spindles and Multi-Tool Turret Units

Overhaul and rebuild services for heavily loaded assemblies of HONGGANG CNC turning centers restore high-precision machining tolerances. Spindle cartridge refurbishment entails selective replacement of matched angular contact bearing sets followed by dynamic balancing and preload calibration.

Rebuilding twelve-position BMT and VDI tool turrets addresses curvic coupling alignment, hydraulic locking seal replacement and servo tool indexing calibration.

Slideway Geometry Alignment and Double Pre-Tensioned Ball Screws

Long-term positioning accuracy of HONGGANG CNC lathes relies on rigid linear slideways and ground ball screws. Mechanical repair procedures involve precision hand scraping of rectangular guide tracks, Turcite-B low-friction lining renewal, gib adjustment and ball screw replacement.

Installing replacement ball screws includes mandatory bi-directional pre-tensioning to minimize thermal elongation during intensive operation, complemented by rigid thrust bearing mounting.

Commissioning Procedures, CNC Parameterization and Circular Interpolation

Commissioning of HONGGANG CNC machine tools covers rigid foundation mounting, anti-vibration leveling and electrical interface verification. Engineers configure axis drive loops, align electronic reference switches and optimize servomotor acceleration curves.

Final dynamic verification utilizes Renishaw circular ballbar diagnostics and laser interferometry to calibrate pitch error compensation and ensure full compliance with ISO standards.

Engineering Selection of High-Precision Components by Machine Nameplate

Precise identification of replacement assemblies for HONGGANG CNC equipment eliminates production interruptions. Engineers verify machine nameplate details, headstock serial stamps and Chongqing Honggang technical assembly schematics.

We support the selection of power chucks, clamping cylinders, feedback encoders and control relays with complete technical documentation and verified factory interchangeability.
