Auto Mass-Production CNC Mill Tongtai TMV-920A: Dual-Spindle for Multi-Material Parts

Unlike general-purpose CNC machining tools, the TMV-920A is engineered to address core challenges in automotive batch production: multi-material processing, long-cycle stability, and seamless automation integration—key gaps that single-function vertical CNC machines often fail to cover.

● Multi-Material Adaptability for Auto Parts: Automotive production requires machining both light aluminum (e.g., engine covers) and heavy steel (e.g., chassis brackets). The TMV-920A’s BT-40 spindle (8000–15000 rpm) handles high-speed aluminum cutting with 18.5 kW motor power, while the optional BT-50 spindle (3500–6000 rpm) delivers heavy cutting torque for steel—eliminating the need to switch between two machines, a common bottleneck in auto lines.

● Batch Precision via Vibration Control: In mass production, even minor vibration can cause dimensional deviations across 1000+ parts. The TMV-920A’s special structure absorbs vibration during continuous operation, paired with large ball screws that reduce motion backlash. This ensures every auto component (from brake calipers to transmission gears) meets tolerance standards, avoiding rework that eats into production efficiency.

● Worktable Design for Auto Part Sizes: The 1000×530 mm worktable (1000 kg max load) fits common automotive medium-sized parts, while X/Y/Z travels of 920/530/530 mm accommodate deep machining (e.g., oil passages in engine blocks). Compared to compact milling centers with smaller worktables, it avoids splitting large parts into multiple setups—cutting per-part processing time by 20%+.

● Automation Tuning for Line Integration: Auto mass production relies on 24/7 unmanned operation. The TMV-920A supports customized upgrades (like 30-tool magazines) to match automated conveyor systems, and its 30/30/24 m/min rapid traverse aligns with production line 节拍 (cycle time) requirements. Unlike manual-load vertical milling machines, it minimizes human intervention, reducing error rates in high-volume runs.

● Cost Savings from Dual Spindles: Instead of investing in separate high-speed and heavy-cutting machines, auto factories use one TMV-920A to handle diverse parts—lowering equipment procurement costs by 30% and saving workshop space.

● Consistency Across Batches: Vibration absorption and stable motion ensure 99.5% of parts meet specs in 10,000-unit batches, a critical metric for auto OEMs (original equipment manufacturers) that require uniform quality.

● Flexibility for Model Changes: When auto brands switch part designs (e.g., updating engine components), the TMV-920A’s customizable spindle and tooling setup adapts quickly—avoiding the long retooling time of specialized CNC turning centers.

● Engine systems: Machining cylinder heads (BT-40 for aluminum finishing) and crankshaft brackets (BT-50 for steel cutting).

● Chassis systems: Processing suspension arms and steering knuckles, leveraging high rigidity to avoid deformation during heavy cuts.

● Transmission systems: Drilling and tapping gear housings, using vibration control to ensure thread accuracy for component assembly.
