164 1990 Fixed - Tornos Bechler User Manual Enc

The "Swiss" turning principle relies on the guide bushing—the heart of the machine. Adjusting the guide bushing clearance requires precise knowledge of the mechanical pre-load and lubrication systems. The user manual details the step-by-step procedures for dismantling and reassembling the headstock and guide bushing assembly, ensuring that concentricity and rigidity are maintained.

The 1990 edition of the user manual was a major revision. It included updates to the electrical schematics (new European safety standards) and improved diagnostic flowcharts for the ENC control panel. tornos bechler user manual enc 164 1990

For a machine operator or maintenance engineer, the shift from cam-operated machines to the CNC logic of the ENC 164 in the 1990s was significant. This is where the user manual becomes an indispensable resource. The "Swiss" turning principle relies on the guide

In the world of Swiss-type automatic lathes, few names command as much respect as . For decades, these machines have been the backbone of high-precision manufacturing, producing tiny, complex components for the watchmaking, medical, and aerospace industries. Among their celebrated lineup, the Tornos Bechler ENC 164 holds a unique place—a bridge between traditional cam-operated automatics and the burgeoning era of electronic numerical control (ENC). The 1990 edition of the user manual was a major revision

The ENC 164 is a mechanical beast with high-speed spindles. The manual specifies the exact type of hydraulic oil and spindle grease required. It also includes the "Lubrication Circuit Diagram," which shows the path of the oil distribution blocks. Neglecting this section often leads to seized spindles or worn guide bushings.

The 1990 user manual contains the specific G-code and M-code definitions used by the Tornos control system. While standard G-codes (G00, G01) are universal, Tornos machines often utilize proprietary cycles for synchronized main spindle and sub-spindle operations. Without the manual, a programmer cannot effectively coordinate the "pick-off" operations or manage the bar puller sequencing.
