Focusing on the core needs of the automotive industry, HTC40Q is mainly applied to the mass machining of automotive shaft components. The core processed workpieces include key shaft parts in the automotive transmission system, steering system and braking system, specifically including: automotive half shafts, gear shafts, motor mandrels, turbocharger shafts, valve tappets, etc. These parts are the core components of automotive power transmission and steering control, which directly determine the stability and safety of automotive driving, and put forward extremely high requirements for machining precision, efficiency and batch consistency.

• Strict Precision Requirements: Automotive shaft parts need to strictly control coaxiality, circular runout and dimensional tolerance, with errors controlled within 0.01mm and surface roughness reaching Ra1.6 and above. Otherwise, it will lead to assembly jamming, accelerated wear and affect the service life of the automobile
• Large Batch Demand: Automotive components are large-scale mass-produced products. A single production line needs to process hundreds or even thousands of shaft parts per day, requiring fast tool change, short auxiliary time, 24-hour continuous and stable operation of the equipment to avoid shutdown losses
• High Difficulty in Material Machining: Most shaft parts are made of high-quality alloy steel, carbon steel and other materials. Some parts need heavy cutting, which puts high requirements on equipment rigidity and spindle torque, and problems such as vibration and deformation are prone to occur, affecting machining quality
• Demand for Multi-Variety Adaptability: There are various types of automobiles and complex specifications of shaft parts, requiring the equipment to have the ability of quick changeover and flexible adaptation, reducing tooling replacement time and production cost
