The first fixed-head lathe in Citizen Machinery UK’s Miyano range to feature the company’s patented LFV (low frequency vibration) chip-breaking software in a FANUC control system is the new, 42 mm bar capacity ANX-42SYY. It features 10 CNC axes including a ±35 mm Y axis on both the upper and lower turrets in addition to X- and Z-axis movements, enabling the production of complex components to tight geometrical tolerances.

LFV involves synchronising the rotation of the spindles with high-frequency oscillating motions of the tools in the X and Z axes to break what would normally be stringy swarf into manageable chips that can be disposed of easily. During turning and drilling, swarf is prevented from entangling around the component and tool, which would otherwise risk damage to both, and prove time-consuming to remove. Machine stoppage for swarf clearance is unrequired, even when machining materials such as stainless steel and plastics.

In addition to LFV software, which is programmable via G-codes in the part program, the 15” (380 mm) XGA touch panel FANUC 31i control features a new Citizen HMI and incorporates the company’s multi-axis technology. This configuration allows three-axis simultaneous cycles, double Y-axis cutting and superimposed machining whereby three tools can be in cut at the same time thanks to X-axis movement of the sub spindle. The technology also helps to share operations between the two spindles more evenly, which helps increase production efficiency and throughput.

The 6.2-tonne machine occupies only 2650 x 1630 mm of floor space. Both main and sub spindle have a bar capacity of 42 mm diameter and are powered by 11 kW/6000 rpm built-in motors.
