3-axis vertical machining center offers high-performance, high-value small parts processing
FLORENCE, Ky, Oct. 8, 2013 – At DISCOVER 2013, Mazak showcased one of its newest small-footprint vertical machining centers, the VERTICAL CENTER UNIVERSAL (VCU) 400 with a Twin-Pallet Changer. The machine brings advanced technology and production volume to high-precision small parts machining for a variety of industries.
Ideal for basic workpiece geometries, the VCU 400 has a 3-axis table that provides effective part processing with quick simple setups. The twin-pallet changer allows the machine to increase spindle utilization and provide users with continuous uninterrupted production. For manufacturers that require 5-axis machining, the VCU 400 is available with a rotary/tilt table, called the VCU 400 5X.
Featuring a powerful, rigid CAT-40 taper 10,000-rpm spindle, the VCU 400 offers unbeatable metal removal capabilities in common materials, including steel, aluminum and cast iron. Other maximum spindle speeds are available, such as 12,000 rpm and 20,000 rpm in 40-taper as well as 42,000 rpm in E40 (HSK), so that users can effectively match spindle performance with their part machining requirements.
The spindle chiller on the VCU 400 maintains a constant spindle temperature to prevent heat build up and improve machining accuracy. Other benefits of the chiller include extended spindle life, increased machining capacity and reduced maintenance costs.
A 20-tool standard storage capacity on the VCU 400 ensures continuous machining operation, while an optional 30-tool magazine is available to further reduce set-up times and increase machining flexibility. To reduce non-cut times, the VCU 400 features a cam-driven automatic tool changer that quickly exchanges tools and gets the spindle back in the cut in the shortest times possible. Reliable tool monitoring on the machine maximizes production efficiency and lowers operating costs via early problem detection.
Axes travels of 19.88” (505 mm) in X, 15.74” (400 mm) in Y and 17.12” (435 mm) in Z allow the machine to produce part sizes up to 15.74” x 15.74” x 9.84” (400 mm x 400 mm x 250 mm). The machine’s three linear axes attain high-speed rapid traverse rates of 945 ipm (24 m/min).
The machine also features Mazak’s MX Hybrid Roller Guide System that enables it to deliver high levels of durability and reliability, resulting in long-term accuracy. The innovative way system increases vibration dampening, extends tool life, handles higher load capacities and eliminates tramp oil in the coolant by utilizing a greener grease-based lubrication system.
The VCU 400 is equipped with the Mazak SMART CNC control. With the user-friendly control, inexperienced operators can quickly and easily develop machining programs to help shorten machine set up times. In fact, programming time is 75 percent faster with the SMART CNC control when compared with machines using EIA/ISO systems, which is especially beneficial when machining a wide variety of less complex workpieces requiring simple turning, milling, drilling and tapping operations.
Based on a modular design concept, the VCU 400 and two other VERTICAL CENTER UNIVERSAL machines – the VCU 300 and VCU 500 – provide the ultimate in manufacturing flexibility via 13 different model configurations, including 3-axis and 5-axis versions, various X-axis travels and pallet changing capabilities.
According to company officials, only Mazak offers such a wide range of machine configurations within one design platform. Whether parts are simple or complex, produced in low, medium of high volumes, the VERTICAL CENTER UNIVERSAL Series has a machine that can offer the perfect balance of advanced technology, increased productivity and maximum value.
