🔍 Introduction: High Precision Production Suitable for Heavy Industry
İş makinaları – özellikle ekskavatör, loader, dozer, greyder ve vinç gibi ekipmanlar – zorlu saha koşullarında çalışır. Bu makinelerde kullanılan her bir parçanın; yüksek yük altında mukavemet göstermesi, aşınmaya dirençli olması ve montaj sonrası %100 uyum sağlaması gerekir. Bu koşulları karşılamak, yalnızca special machining according to technical drawing is possible.
Dogamakina, global companies in this field; CNC machining of pins, bushings, flanges, rollers and special mechanical parts offers. Our productions from prototype to serial production covers all stages until the end.
We offer high tolerance production in the field of construction machinery parts manufacturing and meet your demands for construction machinery parts manufacturing according to the technical drawing.

🔩 Materials Used & Processing Techniques
Dogamakina uses the following materials in parts that require high strength:
Material | Feature | Application |
---|---|---|
42CrMo4 | 1100 N/mm² strength after heat treatment | Pin, flange |
C45 | General purpose medium carbon steel | Body parts |
GGG40-60 | Ductile iron, vibration resistant | Reels |
20nicrmo2-2 | High lubricity, high abrasion resistance | Pins and Bushings |
16MnCr5 | Alloy steel suitable for surface hardening | Bearing housings |
🔥 Heat Treatment Applications: Surface Hardness up to 65 HRC
Dogamakina, in order to increase the strength of construction machinery parts Heat treatment solutions up to 65 HRC offers. Particularly high wear resistance is required such as pins, bushings and gears The heat treatment process plays a critical role in the performance of parts.
Applied Heat Treatment Types:
Induction Hardening
→ With localised hardening, only the contact surface of the part is hardened.
→ Application: bucket pin, pivot pin, shaftCarburising (Carburizing)
→ By impregnating the steel surface with carbon, high hardness is obtained on the surface and toughness is obtained inside.
→ Application: flange adapters, gear shaftsNitration (Nitriding)
→ Wear and corrosion resistance of the surface is increased.
→ Application: internal bearing surfaces, bushings
Dimensional Stability After Heat Treatment
Precision tolerances are achieved again with CNC grinding and finishing after the process.
All hardening processes, hardness measurement reports (HRC, HRB, HBV values).
Examples of Materials Suitable for Heat Treatment:
42CrMo4 → 58-65 HRC after induction + grinding
16MnCr5 → 60-63 HRC after carburising
C45 → 50-55 HRC after tempering
Process steps:
CNC lathe + milling
Internal/external grinding
Threading (Metric & Inch)
Hardness control
Modelling with reverse engineering
