Heavy Machinery

Heavy MachineryIndustrial Parts Manufacturer

Robust CNC machined components for construction, mining, and agricultural equipment with exceptional durability.

CNC Machining Capabilities:

  • Our heavy machinery CNC machining delivers components engineered to withstand extreme operating conditions in construction, mining, and agricultural applications.
  • Our heavy-duty CNC machines handle workpieces up to 3000kg with dimensional tolerances of ISO 2768-mK and surface finish ranges from Ra 1.6μm to 6.3μm depending on application requirements.
  • For hydraulic components, we maintain cylindricity tolerances of 0.02mm and surface finishes of Ra 0.8μm on critical sealing surfaces.
  • We routinely process abrasion-resistant steels (400HB, 500HB grades), high-strength alloys (4140/4340), and specialized cast iron grades (GGG40, GGG50, GGG70) with hardness verification to ASTM E18 standards.
  • Our heat treatment capabilities include through-hardening and induction hardening with case depths of 0.5-3mm and hardness control of ±2 HRC.
  • For wear-critical components, we offer specialized surface treatments including hard chrome plating (50-100μm thickness) and thermal spray coatings to achieve surface hardness up to 68 HRC for extended component life in abrasive environments.
