Single-spindle CNC turning center introduces Y-axis and milling capabilities

June 10, 2024
Murata Machinery USA celebrates 50 years with a machine for high-mix, low-volume production environments

Murata Machinery USA (Muratec) launched its MSR60, single-spindle computer numerical control (CNC) turning center with Y-axis milling capabilities for multitasking machining. Murata’s standard Fanuc 31i control features Manual Guide i, which simplifies programming and automation setup for rapid numerical control (NC) program creation. This year also marks the 50th anniversary for Muratec.

The 8,000 rpm live tool spindle motor on the MSR60 drives high-speed precision applications with a compact footprint and integrated gantry loader automation. Because it integrates milling and turning, Muratec says this machine is ideal for high-mix, low-volume production environments. The MSR60 introduces Y-axis and milling capabilities on a single-spindle machine (Figure 1).

The MSR60 is a CNC turning center with front-facing 6-in/8-in chucks equipped with a Y-axis. It has a single 10-station turret, an X-axis stroke of 240 mm, a Y-axis stroke of ±60 mm, a Z-axis stroke of 200 mm and a maximum spindle speed of 6,000 revolutions per minute.

The MSR60’s width is 1,555 mm, and its depth is 2,350 mm, half the size of the MWR120, but it has twice the range of motion or stroke typical for a turning machine its size.

“The MSR60 enhances Muratec’s overall single-spindle lineup, combining powerful processing capabilities within a compact design tailored for job shops just starting their automation journey,” said Jeff Kalmbach, general manager, machine tools division, Murata Machinery USA. “With the introduction of milling and Y-axis functionalities previously unavailable on a single spindle turning machine, the MSR60 enables extreme multitasking, creating complex shapes from raw materials to finished products without the need for changeovers. This innovation addresses the industry’s near-constant labor shortage and eliminates the necessity for secondary operations, streamlining production and boosting efficiency.” 

Other key features of Muratec’s MSR60 single spindle CNC turning center include rapid shutter-to-shutter time on the spindle, reduced spindle acceleration-deceleration and a minimized turret index time. The MSR60’s optional gantry loader can handle a range of workpiece varieties, enabling unattended cell and system activity. It is also available with a dual gantry loader for a faster, more efficient run time.

Muratec’s machinery interconnectivity allows each machine to function both independently and in tandem to provide versatility. The MSR60 single-spindle machine and the MWR120 twin-spindle machine are designed to operate independently or seamlessly together for prolonged periods.

The MSR60 can also be integrated with another twin-spindle machine, enhancing its adaptability. For instance, if a customer requires three spindles for optimal cycle time, they could use two general turning machines for the initial spindles and an MSR60 for the third spindle that requires a Y-axis.
