For Graphite and Hard-Milling Applications

New machine offers high precision and superior surface finish and tool life

Makino’s newest vertical machining center is ideal for operations wanting high precision, high-speed milling of both graphite and steel. The E33 offers a rapid traverse and cutting feedrate on all axes of 1,574 IPM and maintains low vibration characteristics, while also creating superior surface finishes. Extended tool life and advanced controls add to the machine’s overall ease of use and unattended operation time.

Built with automation in mind, the E33 comes standard with SGI.4 for reduced cycle times and a Pro.5 controller. The machine comes standard with an HSK 40,000 RPM spindle, with Makino’s patented core-cooled spindle. It comes standard with a 30-tool automatic tool changer, with an optional 60-tool changer.

Features and Advantages
The E33 has an X-axis of 650 mm (25.6 in.), and Y- and Z-axes of 450 mm (17.7 in.). The standard work table is 850 mm x 500 mm (35.5 in. x 19.7 in.) and work load capacity is 500 kg (1,102 lbs.). Standard positioning accuracy of +/-0.003 mm (±0.000118 in.) with optional positioning accuracy with scale feedback of +/-0.0015 mm (+/-0.000059 in.) enables highly accurate cutting.

The E33 offers standard repeatability of +- 0.002 mm (±0.000078 in.) and optional repeatability with scale feedback of ±0.001 mm (±0.000039). And while it weighs in at a rugged 16,090 pounds (7,300 kg) for solid rigidity and stability, it comes in a compact size ideal for any shop. It has a width of 89.9 inches (2,284 mm), a height of 119.6 inches (3,038 mm) and a length of 99.4 inches (2,525 mm). The dust collection system brings the length to 136.4 inches (3,465 mm).

The high performance Pro.5 control offers a user-friendly graphical user interface (GUI) that is easily configurable, and Makino’s proprietary Data Center serves as a repository and interface for networking and seamless communications. SGI.4 ULTRA, the latest generation of Makino’s patented, high-accuracy 3-D software is ideal for complex surfaces because of its minimum machining time.

Clean Machining
The E33 features a fully enclosed chip and splash shield that completely seals the workzone and prevents dust and chips from escaping. A center chip trough uses a scrapper-type chip conveyor and a fully integrated dust collection system keeps the machining zone clean.

No one will do more to lower machining costs than Makino, a global provider of advanced machining technology and application support for the metalcutting and die/mold industries. Makino manufacturing and service centers are located in the United States, Japan, Germany, Singapore, Italy, France, Korea, Taiwan, Turkey, China, Mexico, Brazil, and India, and are supported by a worldwide distributor network.
