Smart CNC Lathe

ST-Series

ST Series is an integrated multiplex turning center that combines the processing capabilities of a turning center with those of a machining center via Y and C axis control. The versatile 12-station power turret allows it to completely manufacture parts with complex shapes in a single setup operation.

The launch of the ST Series is the pursuit of the maximum potential of flexibility, accuracy, reliability, and productivity.

Features

  • One-piece cast iron foundation is a true 30-degree slant bed casting, providing large mass in a small footprint. More mass means higher rigidity and better heat dissipation.

  • The patented slant bed design increases the X-axis travel to 220mm, Y-axis travel to 40mm and Z-axis to 350mm reducing the lathe size and stability.

  • Equipped with a CNC program-controlled hydraulic tailstock, a 12-station power turret, a power milling head can be installed at the upper or bottom position of the Y-axis (turret), high rigidity cutting, suitable for long-axis turning, milling, Processing of complex multi-process products such as drilling and tapping.

  • The main spindle is with C-axis function, high speed, high precision, and low vibration which can make the workpiece precise. Each spindle bearing assembly was tested for dynamic balance before installation to ensure high-speed running stability.

  • Equips with Taiwan ball screw rod rail and linear guideway to provide precision and low vibration tool carriage movement.

  • Equips with auto lubrication system to ensure transmission system smoothly and long-lived.

  • A robust hydraulic collet chuck can hold bars up to φ51mm and a single workpiece up to φ62mm.

  • SYNTEC CNC system co-works with quality electrical parts providing a rapid-operation and durable use.

Application

Competent to handle the turning process with brass, bronze, aluminum, steel, stainless steel, and rigid plastic with bars diameter up to Φ51 mm or single workpieces up to Φ300mm. High Rigidity casting iron body provides the possibility of higher hardness materials and better smoothness (smaller roughness). ST-52YT is equipped with a CNC program-controlled hydraulic tailstock, a 12-station power turret, a power milling head that can be installed at the upper or bottom position of the Y-axis (turret), high rigidity cutting, suitable for long-axis turning, milling, Processing of complex multi-process products such as drilling and tapping.

Case Study

Configuration: ST-52YT installs the 3-Jaw Hydraulic Chuck, Power turret.

Workpiece: Connection shaft, 45 steel.

Machining Process: Turning, Facing, Drilling, Milling.

Turning Duration: within 380 seconds of one-time processing
