Measurements

Our laser alignment systems are designed for checking and correcting the alignment of all kinds of different applications. Typically for each application there are 4 main alignment parameters need to be checked: flatness, straightness, squareness and parallelism. Our lasers can do them all with ease, but they can also be used to measure concentricity (alignment) of bores and co-linearity of rotary axes, as well as, the angularity of linear axes, such as: pitch, roll and yaw, which are needed from time to time in machine tool axis alignments.

Concentricity

Two bores are said to be concentric if the position of the center point of each bore is nearly the…

Flatness & Leveling

A surface or axis travel is said to be flat to a tolerance if all the points on that surface…

Parallelism – Linear Axes or Surfaces

Two surfaces or axes are said to be parallel to each other if the angle between the axis lines (usually…

Parallelism – Rotary Axes

A rotary axis is said to be parallel to a linear axis if its rotation plane has zero angle relative…

Pitch of a Linear Axis

As a linear axis travels along the Y axis, the pitch angle of the axis is a measure of how…

Roll of a Linear Axis

As a linear axis travels along the Y axis, the roll angle of the axis is a measure of how…

Spindle Tramming

In machine tool alignment, tramming a spindle refers to a process where the axis of rotation (AOR) is aligned perpendicular to…

Squareness – Rotary Axes

Similar to spindle tramming, a rotary axis is said to be square to a linear axis if the angle between…

Squareness – Linear Axes or Surfaces

Two surfaces, or linear axes, are said to be square (or perpendicular) to each other if the angle (usually the…

Straightness

Similar to flatness, a surface or axis travel is said to be straight to a tolerance if all the points…

Yaw of a Linear Axis

As a linear axis travels along the Y axis, the yaw angle of the axis is a measure of how…
