Linear Translation Stage Technology Guide

The function of a linear translation stage is to constrain motion along an ideal straight line. Any undesired motion in constrained directions will contribute to deviation from the ideal trajectory and/or final position.

Contributors to deviations include load forces and issues in designing and constructing a perfect linear translation stage in a world where perfect machining and ideal materials do not currently exist. For detailed information on precision positioning please see Manual Positioning Basics, or see Motion Basics and Standards if you are interested in automated motion control.

Features: High precision micrometer screw linear translation platform lightweight material, resistant to cold flow or creep, with good stiffness-to-weight ratio. It has a relatively high coefficient of thermal expansion, but it also has a high thermal conductivity, making it a good choice in applications where there will be thermal gradients or where rapid adjustment to temperature changes is required.

Aluminum is fast-machining, cost-effective, and widely used in stage structures. Aluminum does not rust, and corrosion is generally not a problem in a typical user’s environment, even when the surface is unprotected. It has an excellent finish when anodized.

Anodized aluminum provides excellent corrosion resistance and a good finish. Black is the color most often used. Anodizing hardens the surface, improving scratch and wear resistance. Aluminum may also be painted, with excellent results.

Steel

Features: Steel has a high modulus of elasticity, giving it very good stiffness (nearly three times that of aluminum) and good material stability. It also has about half the thermal expansion of aluminum, making it an excellent choice for stability in typical user environments where there are uniform changes in temperature. Stainless Steel is well suited to high vacuum applications.

Limitations: Machining of High precision micrometer screw linear translation platform steel is much slower than aluminum, making steel components considerably more expensive. Corrosion of steel is a serious problem, but stainless steel alloys minimize the corrosion problems of other steels.

Coatings: Steel parts are generally plated or painted. Platings are often chrome, nickel, rhodium, or cadmium. A black oxide finish is often used on screws and mounting hardware to prevent rust. Stainless steel alloys avoid the rust problems of other steels. They are very clean materials that do not require special surface protection. A glass-bead blasted surface will have a dull finish so that it does not specularly reflect.

Brass

Features: Brass is a heavy material, denser than steel, and fast machining. The main use of brass is for wear reduction; it is often used as a dissimilar metal to avoid self-welding effects with steel or stainless steel lead-screws or shafts. Brass is used in some high precision applications requiring high resistance to creep and can be diamond turned for extremely smooth surfaces.

Limitations: Compared to aluminum and steel, brass has a less desirable stiffness-to-weight ratio. Moreover, although the thermal expansion of brass is similar to that of aluminum, its thermal conductivity is nearly a factor of two worse.

Coatings: For optical use, brass is usually dyed black. In other cases, it may be plated with chrome or nickel for surface durability.
