The TNL18 and the TNL18P are sliding headstock automatic lathes designed to be changed over quickly to produce precision parts with or without a guide bushing. The machine can produce long or short parts from bars as large as 20 mm in diameter. As many as three tools can engage the part simultaneously.
The machines are designed for medical component machining, delivering precision and surface finishing in a single operation. The tool capacity of the TNL18 can be increased to as many as 54 tool places through dual- and multi-holders. Features of the tool change system enable chip-to-chip time of 0.3 sec.
The lathes are designed to be changed over for use with and without a guide bushing for long or short parts. The Z-travel distance of the headstock ensures the positioning of the main spindle, either for turning with a guide bushing or without. In the standard design, the main spindle is equipped with a C axis and provided with either a direct drive with high dynamic response or a belt drive (TNL18P) and high torque in order to achieve large cutting volumes.
According to the company, simultaneous machining with multiple tools ensures high productivity levels by both machines. As many as three tools may be used simultaneously on two spindles.
