Automatic Detection of Hole Machining Anomalies! What Is the Revolutionary Customization of the CITIZEN CNC Automatic Lathe CincomL12?
In this blog, we will introduce METROL's high-precision MT touch switch [P10DB-A], which can be optionally mounted on CITIZEN CNC automatic lathe CincomL12.

Automatically detects drilling abnormalities
- Automatically detects post-machining drilling abnormalities and, in the case of a defect, stops operation automatically. Prevents mass production of defective products.
- Reduces 100% manual inspection process.
- Minimizes defective products and thus minimizes costs (materials, machining time).
Automatically detects drilling defects in 2 steps
STEP.1 Checks whether drilling is taking place normally
[Abnormal] Insufficient drilling ▶︎ Detection rod breaks
STEP.2 High-precision Touch Switch confirms detection rod status
▶︎Machining continues with no problem
[Abnormal] Detection rod does not contact touch switch
▶︎ Machining stops automatically! Machining defects prevented in advance
Touch switches and detection rods can be customized by the manufacturer (retrofitting is possible).

Sliding Headstock Type Automatic CNC Lathe
Cincom L12X
Citizen's newest development, the L12X with Y2 axis for even higher functionality
Y2 axis Type X to the back spindle strengthens back machining. This increases the degree of freedom for process allocation, and increases the maximum number of tools that can be installed to 38.
- The wide variety of tooling layouts available, such as "adjustable angle end-face spindle" that allows for slanted hole drilling, enable you to perform various kinds of machining.
- Additionally, adoption of a built-in motor for the back spindle drive enables a maximum speed of 12,000 min-1.
- Citizen Machinery's patented swarf control technology, LFV. Three vibration mode (mode1, mode2, mode3) are currently available.
