Mold processing enterprises generally face a dilemma: the hardness of mold steel is high, and deep cutting is required during the roughing stage, which requires extremely high rigidity of the machine tool; The precision machining stage requires micrometer level dimensional accuracy and excellent surface smoothness. Some equipment on the market experiences significant body vibration during heavy cutting, and the precision of precision machining does not meet the standard. Therefore, companies can only purchase two separate machines, rough machining and precision machining, which require a large investment in equipment and require the workpiece to be transported back and forth, thereby extending the overall delivery cycle. At the same time, the mold industry has multiple varieties, small batches, and frequent production changes, which also puts high demands on the flexibility of machine tools.
To balance strong roughing and precision machining at the same time, the rigidity of the machine tool bed is the foundation. Harman Precision TL2000 heavy-duty series and high-precision standard series can cover the entire process of mold processing. The TL2000 heavy-duty series adopts a large cross-section integral casting bed body, matched with an A2-8 high torque spindle, and a hydraulic power turret that can withstand large cutting depths and feed rates, efficiently completing the rough cutting operation of mold steel. The high-precision standard series is equipped with an intelligent thermal compensation system, which achieves a stable precision of ± 2 μ m in precision machining, ensuring the form and position tolerances and surface quality of mold inserts, punches, and cores.
The entire series of equipment can be equipped with optional power turret and Y-axis turning and milling composite functions. Rotary mold parts can be machined, milled flat, and slotted in one clamping, reducing fixture investment and shortening processing cycles. FEM finite element optimization of bed structure, effective absorption of vibration during heavy cutting, and avoidance of vibration pattern defects.
The mold factory frequently changes production and has a large workload for process debugging. The Harman Precision Technology team can conduct selection evaluations for mold parts and provide processing technology recommendations. From incoming inspection of components to full chain quality control of the entire machine, ensuring long-term stability of the equipment. Combined with preventive inspections and original spare parts supply, we help mold manufacturers reduce equipment downtime due to malfunctions, shorten mold delivery cycles, and improve part yield rates.
