CNC Parts Machining For Automotive Industry
Complete Processing Capabilities & Equipment
Our factory is equipped with industry-leading CNC machine tools, capable of handling various CNC parts machining requirements for the automotive industry.
● 5-axis CNC milling centers: For complex 3D geometries, undercuts and multi-sided machining in a single setup
● Swiss-type CNC lathes: For high-precision small parts with diameters from 0.2mm to 32mm
● Horizontal machining centers: For high-volume production of structural components and housings
● CNC grinding machines: For ultra-precision surface finishes and tight tolerance cylindrical parts
● Wire and sinker EDM: For hard materials and intricate features that cannot be machined with conventional tools
● Secondary operations: Deburring, threading, knurling, laser marking and assembly services
FRIMA’s total monthly production capacity reaches 2.5 million pieces, with dedicated production lines for prototype, pilot and mass production orders to ensure no scheduling conflicts.
