Machine Alignment System

Hamar Laser Instrumentso make it easier to measure and control machine tool geometry, eliminate twist or bend in ways, and analyze line of motion, the L-719 machine leveling package provides a completely flat plane of light, target, and readout to make flatness and levelness comparisons.

Computers, interfaces, and special software upgrades are available for this package. The computer upgrade turns machine alignment into a step-by-step procedure.

In this system, one laser turret operates in scanning mode. Within the laser, the projected beam is bent 90° by a pentaprism; the beam comes out from an aperture in the turret side. As the turret rotates, the laser beam is swept 360° to create an extremely flat plane of light. The system has an integral precision leveling base with bubble level vials, which provides visual leveling accuracy of 20 arc-seconds per 2 mm division, as well as micrometer adjustments for pitch and roll. If equipped with at least one target, the system can measure machine flatness and levelness in one operation.

The lasers are mounted either on a machine or stable base so the plane of light created by the laser is parallel to a line or plane of reference, a set of points, straight edge, or flat surface. Lasers also can be tilted and mounted at a 90° angle to produce a vertical scan plane.
