ASIATOOLS TH-series duplex milling machines serve four-sided milling in mold base uses. They balance detail, cutting strength, and value. Models such as the TH-1300NC shine in processing big workpieces in one go. This cuts down on cycle periods. It also boosts detail for four-sided cutting jobs.
To select the right duplex milling machine for four-sided operations, consider these points.
1. Workpiece Size and Handling
Four-sided milling usually requires a wide workspace. The machine ought to offer plenty of travel along the X, Y, and Z axes. This accommodates mold bases in various dimensions. For instance, the ASIATOOLS TH-1300NC model supports workpiece dimensions reaching 1300×800×600 mm. Therefore, it suits substantial mold bases effectively.
2. Automatic Tool Changing
For effective four-side milling, automatic tool exchange features prove essential. They minimize downtime between swaps. Moreover, they enhance the machine's overall utilization.
3. Cutting Capacity
The equipment needs to address both rough and finish cutting requirements. This applies directly to mold base production. In that process, initial roughing precedes the final finishing. Units like the ASIATOOLS TH-430NC and TH-600NC feature multiple cutting capabilities. As such, they provide flexibility for four-sided work.
4. Simultaneous Control
For four-sided milling, the machine must oversee both heads separately. Meanwhile, it performs different tasks concurrently. This approach shortens cycle lengths and raises throughput. Verify that the CNC system supports multi-axis functions.
