New TRIMILL VU 3021 | Vertical Machining Centers (5-Axis or More)

Description

The VU Series features a TRIMILL trademark of rigidity and thermal stability with its box-in-box gantry design and UHPC (ultra high performance concrete) concrete side walls. The result is high accuracy and repeatability. 5-axis machining is achieved with a rotary table and main spindle tilt. For 6-axis machining, rotation of the main spindle head is available. Machining five sides in a single setup with the option to extend the X-axis 39.4”(1,000 mm) increments makes the VU Series a productive choice for large format machining.

TRIMILL PRINCIPLE: BOX-IN-BOX and UHPC

The box-in-box is a unique system of closed construction of the cross-beam and cross-slide with internally positioned and guided ram unit (axes Y an Z). UHPC is a high strength concrete with excellent properties for vibration damping and thermal stability of machines.

THE ADVANTAGES OF TRIMILL PRINCIPLE:
• Consistent milling results thanks to stable thermo-symmetrical
arrangement on linear guideways
• Always 4 guides of the cross and vertical support for the machine, preventing the occurrence of the so-called „banana eff ect“ which deforms/bends the vertical support of the machine
• Increased rigidity of the machine in the X axis by +60%, in the Y axis by +30% and in the Z axis by +90%

ADVANTAGES OF USING UHPC:
• The columns and longbeams of most TRIMILL machines are made of high-strength concrete (UHPC).
• Maximum vibration damping and extended tool life
• Low thermal conductivity and high heat capacity resulting in high thermal stability of the machines
• Compressive strength ≥ 150 Mpa => 6 times stronger than C20/25 concrete
• Production in our own concrete plant in TRIMILL, a.s.
