Marubeni Citizen-Cincom, Inc. is proud to introduce the new R07 Swiss-type turning center specializing in the fast and efficient machining of small diameter parts up 07 mm diameter.

The R-series CINCOM products were developed by Citizen for high-speed, high-precision machining of tiny precision parts. The new CINCOM R07 is compact like the current and popular R04 but has a maximum machining diameter of 07 mm. The R series machines specialize in machining small-diameter parts thus offering a wider range of high precision work pieces for specialized parts

The new R07 offers a compact rotary guide bushing unit developed exclusively for high-speed, high-precision machining. With this new rotary guide bushing the R07 can perform metal cutting at high speeds of up to 12,000 RPM. The sub-spindle delivers 10,000 RPM. The R04 with its stationary guide bushing has a maximum spindle speed of 16,000 RPM, with10,000 RPM on the back spindle as well.

The R series machines use linear motors to drive the slide and tool posts. This system achieves fast part processes with quick response and quiet operation as well as eliminating thermal distortion. A scale feedback control system is also used with all axes, which offers the perfect machine configuration for machining small, high-precision parts.

Even while the super-high-speed built-in spindle motor is running at a high speed, the chuck can be opened or closed without first decreasing the speed. This feature reduces non-cutting idle time, which would result from acceleration and deceleration of the spindle. Use of two independent tool posts on the machine increases operation efficiency eliminating idle time due to a tool exchange.

Complementing the R series machines is the optional ALPS Automatic Bar Loader. This special bar loader is specifically designed to grasp and feed small wire-like bars into the machine.

The R series CINCOMs are also offered with an optional vacuum type part removal system and carousel work piece separator specially designed for small-diameter (Tiny) part removal. This system can greatly improve productivity.

Rotary tools are now part the gang tool post. This allows small-diameter parts requiring complex machining such as polygon turning and end face drilling be machined easily.

The R series CINCOMs with their use of a built-in spindle and linear motor, reduce the size of the machine footprint saving valuable floor space by 40% compared to that of the B-12. This small compact size considerably increases the manufacturing production area of the plant.

Marubeni Citizen-Cincom was founded in 1984 to market and service Citizen’s CINCOM (CItizen Numerically COntrolled Machines) family of Swiss-type turning centers. This venture represents the amalgamation of two of Japan’s largest and most highly regarded companies, Marubeni Corp. and Citizen Watch Company.

Since its inception, MCC has successfully made CINCOM machines the most widely accepted Swiss-type turning centers in the world. These machines are used extensively to manufacture an array of products, including medical instruments, electronics, fiber optics, automobiles, business machines, aerospace, defense, firearms, tools, valves, fasteners, and many others.

In the US, MCC is headquartered in Allendale, NJ, and maintains sales-service offices in both California and Illinois. These three offices are responsible for supporting a nationwide network of 26 distributors located throughout the United States.
