Engineering Machinery Manufacturing Solutions
Engineering Machinery Manufacturing Process
Raw Materials And Incoming Materials Inspection
- Verify alloy grade/casting‑forging quality, dimensions and heat‑treat state; sample chemistry and hardness.
- Optical spectrometer, universal testing machine, CMM, ultrasonic flaw detector, hardness tester.
Casting/Forging Prep And Roughing
- Remove risers/flash, shot‑blast, then rough‑turn/mill datums on links, pins, bushes and sprockets.
- Swing frame grinder, shot blaster, CNC lathe, milling machine, machining center.
Benchmarking And Critical Machining
- Establish reference faces and finish critical bores and interfaces with on‑machine probing compensation.
- Horizontal boring milling machine, jig borer, machining center, on‑machine probe, precision fixturing.
Spline/Keyway And Gear Profile Forming
- Form internal/external splines, keyways and sprocket tooth profiles to stock‑for‑grind.
- Broaching machines, milling machines, drilling machines, on-machine measuring heads, compensation systems.
Heat Treatment
- Carburizing/quenching/tempering or induction hardening and stress relieving after tempering.
- Carburizing furnace, quenching furnace, tempering furnace, induction hardener, stress relief furnace.
Precision Straightening
- Correct distortion on long pins/shafts and verify straightness online.
- High‑precision straightening machine, laser distance gauge, multi‑point straightening fixture.
Precision Grinding And Geometry Control
- Grind OD/ID/face and bearing seats to roundness/cylindricity/flatness requirements.
- Gear grinding machine, profile modification system, lead crowning system, gear measuring center.
Surface Engineering For Wear Zones
- Locally harden or clad wear areas (pin journals, bush ID/OD, sprocket teeth) and polish to spec.
- Induction/laser hardening machine, laser cladding or HVOF system, polishing/finishing machine.
Deburring And Cleaning
- Remove burrs by robot/high‑pressure/electrochemical deburring and achieve cleanliness via multi‑stage ultrasonic wash and drying.
- Robot deburring cell, high‑pressure deburring unit, electrochemical deburring unit, ultrasonic washer, vacuum dryer, cleanliness tester.
Assembly And Testing
- Assemble gearbox, set bearing preload/backlash, then run gear mesh, noise, and leak tests for 100% units.
- Assembly line/fixtures, gear meshing test bench, noise/vibration tester, leak test bench, torque/drag tester.
Final Inspection and Packaging
- Perform CMM inspection and visual check, laser mark ID/traceability, and apply anti‑rust packing for shipment.
- CMM, laser marking machine, barcode printer/scanner, vacuum/VCI packaging system.
Data Traceability And Quality Control
- Record process/inspection/assembly data via MES and SPC for full traceability and rapid containment.
- MES, data acquisition system, SPC software, QMS with barcode/RFID.
