VMC's with Linear Guideways

Chevalier is now offering a full range of VMCs with linear guideways: 2033VMC-L (33"x20"x20"), 2040VMC-L (40"x20"x20"), and 2552VMC-L (52"x25"x25"). The new models feature THK NR linear guideways on X & Y axis. The 2552VMC-L has 4 linear guideways on the cross travel while the 2033VMC-L and 2040VMC-L have 2 linear guideways. All models have rigid square ways on the Z axis. With this new design, Chevalier VMC's now offer faster feedrate during high speed machining: 1181ipm rapid travel on X & Y axis, 709ipm at Z axis and .04 to 300ipm cutting feedrate. The Z axis has a counterweight with dual bearings that helps it handle heavy loads efficiently while maintaining smooth movement and accuracy.

The spindle motor peaks at 8000rpm and has an extra-wide timing belt, which reduces noise, improves transmission power and eliminates slips. Standard equipment in the new models is a 15HP spindle motor for the 2033/2040VMC-L and 20HP for 2552VMC-L. Load capacities range from 1100lbs for the 2033VMC-L, 1320lbs for the 2040VMC-L and a hefty 2640lbs for the 2552VMC-L. As with the new big VMC models, the 2552VMC-L uses a floating type tool discharge system which puts the unclamping pressure on the spindle's main structure, not on bearings, dramatically prolonging spindle bearing life.

The tool changers on all models have a bi-directional access random tool selection for convenience and easy maintenance. Two tool changer types are offered: standard carousel type with 20 tools and optional arm type with 24 tools. The carousel type has a pneumatic direct changer, with each cylinder equipped with a cushioning device for accurate and stable motion. The arm type automatic tool changer with cam construction shortens tool change time. An automatic air blower keeps the spindle clean during tool change. The drive cards, motors and control are all FANUC and come with a 2-year warranty. The major machine components are made of heat-treated Meehanite cast iron. Enhancing the rigidity of the entire structure is the box type, ribbed design of the column and machine base.
