MCC Lathes Improve Productivity, Operating Convenience
MCC’s M532 VIII and L12X have added capabilities to improve productivity.
Marubeni Citizen-Cincom’s (MCC) Citizen’s M532 VIII and the L12X are Swiss-style lathes with added functionalities for operating convenience and improved productivity, according to the company. The M532 VIII is a Citizen Cincom M series turret-style Swiss turning center with a 32 mm capacity machine that has the capability to increase to 38 mm. Its standard 12 cutting axes includes a B axis for angular drilling and contour milling, while the 10-station turret with half index capability provides 20 positions. The Cincom L212X features the all-axis simultaneous Cincom system M70 Control (Mitsubishi Meldas 70LPC-VU), as well as a 15,000-rpm main spindle. The machine has a Y2 axis on the back spindle which expands the range of usable tools. The maximum spindle speed has been increased to 12,000 rpm to shorten acceleration/deceleration times. The company says that both machines employ a user-friendly editing function which utilizes multiline, multi-axes programming along with superimposed and synchronized control to simplify setup.
CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
This article discusses the use of high-speed spindles in Swiss machining applications. Sufficient rotational speed is necessary to take advantage of tooling materials in small diameter cutters.
Hard turning isn’t hard to do. However, it does require an understanding of the process dynamics and a systematic approach to the tooling involved. This article looks at how proper preparation will deliver consistent, predictable hard-turning results.
