400 TECHNICAL INFORMATION Guide: Linear Ball Clamp Feed:Micrometer Head (Resolution 0.01mm) 2What is a Stage? Stages are mechanical unit products composed of Guides, Feed mechanisms, and Clamps. Since they can easily adjust object positions for inspections, machining, and assembly fixtures. A single unit would be used as an X-Axis, and two units can be combined as an XY-Axis stage. Use a Z-Axis for height adjustments. 2Linear Guidance Structures Dovetail Slide Cross Roller Linear Ball Structure Sliding male/female trapezoid grooves facilitate the guiding. Caged cylindrical rollers are alternately crossed, and placed between two grooved rails. The rolling motion of the rollers facilitates the guiding. Steel balls are aligned in gothic arch grooves machined on the body of stage. The rolling motion of the rollers facilitates the guiding.

Applied loads exceeding the friction of the clamp mechanical forces can displace the stages. Please devise proper countermeasures to prevent the stage surfaces from being displaced in actual applications. MISUMI offers the following clamp reinforcement measures. t Selecting the Reinforced Clamp Type Stages (Slit Type Clamp) t Changing the clamp type when available as "Alterations" (Opposed Clamp, Disc Clamp) 2About Clamp Mechanism Standard Clamp Disc Clamp Opposed Clamp Slit Clamp Lever Clamp Stage Surface Clamp Screw Clamp Plate Disc Clamp Screw Bolt & Nut Features Clamp plate is pressed against the side of the stage by a clamp screw. It is the most economical and standard holding method. The stage is immobilized by clamping a disc applying no load on the stage surface. The advantage is that position displacement can be prevented. The carriage is braced by a bolt from the other side of the micrometer head. The bolt is secured with a nut for vibration resistance and strong holding capacity. The feed knob shaft is clamped directly. Compared to the conventional model, larger retaining force can be obtained. Drift can be prevented by using it in combination with conventional standard clamp. The final tightening action of the clamp screw is managed with a lever for easy operation. 2About Feed Mechanisms Rack & Pinion Feed Screw Feed Screw Micrometer Head Coarse/Fine Micrometer Head Digital Micrometer Head Guide Mechanism Dovetail Slide Cross Roller / Linear Ball Slide Travel per Rotation 17~20mm 0.5~10mm 0.5~1mm 0.5mm 0.025~0.5mm 0.5mm Features t Suitable for rapid feeding. t Not suitable for accurate positioning. t Suitable for fine feeding and slightly fast feeding. t Screw lead selectable t Suitable for fine feeding. t More economical compared to Micrometer Head t Not scaled and incapable of numerical adjustments. t Suitable for precise positioning by 0.01mm. t Enables finer adjustment compared to standard Micrometer Head. t 0.5μm Graduation t With digital display, output t 1μm Graduation Positioning Stages Overview
