L32
A best-selling machine with a legacy at Cincom, the L32, has seen the launch of 4 new models with a modular design. Ranging from a 7-axis machine with excellent cost performance to a high-end machine equipped with B axis and back tool post Y axis, you can select the machine according to the functions you require.A wide range of modular tooling ensures that the new L32 is both versatile and flexible to meet your production demands into the future.
Cincom’s Time-tested L Series Adopts Modular Design
LFV function is now available on all axes

Function modules that can be combined without restrictions
The LFV function available as an option for effective machining of difficult-to-cut material (optional)
LFV (low-frequency vibration cutting) is a technology for performing machining whilst oscillating the X and Z servo axes in the cutting direction in synchronisation with the rotation of the spindle. It reduces all problems caused by swarf entangling with the component or tool, and is effective for small-diameter deep hole machining and the machining of difficult to chip materials.
With a modular design, the L32 has a lineup of four Types – VIII, IX, X and XII – which can be combined with selected variations: rotary tools on a gang tool post, an opposite tool post, or a back tool post.
The guide bush can be fitted and removed in a quick and simple operation. When machining long thin workpieces, the machine is used as a guide bush type. When producing less than two and half times diameter components, it can be used in guide bushless mode. The benefits are shorter bar remnants and ability to use bar stock with variable diameter tolerance.
There is an option to increase to 38 mm diameter spindle capacity. The maximum machining length per chucking is the same as the standard specifications at 320 mm.
A workpiece conveyor is equipped as standard to facilitate the efficient unloading of high volume parts production.

Equipped with high-speed NCThe machine is equipped with the latest NC model to drastically reduce the start-up and screen switching time compared to conventional machines with advanced functions.
Display of code listThe function displays the list of G and M codes including explanations to aid programming.
On-machine program check functionUsing manual handle feed, operations can be run in the forward or reverse directions, and you can temporarily stop program operation, edit the program, and then restart operation.
Eco screenThe current power consumption is shown on the screen, along with the cumulative power consumption, and the power regeneration (generation) status.
Display of easily understood illustrationsIllustrations appropriate for each item are displayed. You can see what they mean at a glance (the screen shown above displays the machining data).
Eco screen (example graph display)The machine’s power consumption can also be shown in the form of an easy-to-understand graph.
Multiple tool post overlapping functionIndependent opposite and gang tool posts are provided. In front machining, idle time has been completely eliminated by using a unique control method. The next tool post to be used starts preparation for machining without waiting for the other one to complete its retraction operation.
Direct spindle indexing functionThis substantially reduces spindle indexing time. When indexing the spindle, this function allows the spindle to be decelerated and stopped at the required index position by specifying this position with a C-axis command while the spindle is rotating. This eliminates the idle time up until rotation stops, and improves working efficiency.
