Specification Overview of Z-Axis
■The movement amount of Z-Axis
drawing size is when the stroke is 0 mm, and the distance moved left and right based on this is the movement amount.
■Load capacity of Z-Axis
If it is used in excess of the rated load, the slide table may not move smoothly or may become stuck. Refer to the load capacity when installed horizontally and the "vertical" value when installed vertically,respectively.
Please note that the accuracy may be lower than the values indicated in the product catalog if the slide table is installed vertically or upside down.
■Straightness This
refers to the maximum offset to the ideal movement axis (the straight line connecting the start point and the end point, the red line in the figure below. The black line is the actual motion trajectory) when driving theslide table. Moves the full stroke.
Detection method: Place a dial indicator on the slide table, place the pointer on the reference block, move the slide table the full stroke, and then measure the maximum displacement, i.e. straightness.
How to use of Z-Axis
■How to install the X-axis sliding table
When installing the sliding table on the base, the method of moving the sliding table is basically adopted. See the image below.
Choose from horizontal, inverted, side horizontal or vertical side installation. Caution is required for other installations.
Load resistance and accuracy vary greatly depending on the mounting posture.
○: Same level of load resistance.
△: Approximately 1/3 of the horizontal load resistance is a rough guideline, and the vertical load resistance listed in the product catalog is recommended.
■Using the X-axis slide table vertically
When using the X-axis slide table vertically, be careful with the travel direction not in the same direction as gravity.
When using the micrometer handle type slide, the slide is returned by the tension spring. If a force exceeding the spring load is applied, the slide table may fall.

■Stage usage environment of Z-Axis
Usage environment: 10~50℃, 20~70%RH (non-condensing)
Recommended usage environment: 22±5℃, 20~70%RH (non-condensing)
■Guide mechanism of Z-Axis
Since a cross roller guide is used as the guide mechanism, inject lubricant in a timely manner according to the usage conditions to prevent the life of the cross roller guide from being reduced and deteriorated due to lubricantreduction.
■Clamping mechanism of Z-Axis
①The clamping mechanism of the slide table is fixed by the frictional force generated by the fastening screw, so if the external force exceeds the frictional force of the clamping mechanism, the slide table will move. The user must takeappropriate measures during use to prevent the table surface from moving.
②Holding force refers to the value of the force that prevents the slide table from moving in the clamped state. The maximum holding force varies depending on the tightening torque, so ensure sufficient safety factors when designing.
■A slide table with a micrometer knob mounted on the transport mechanism is generally called a standard type if it has a shape like the figure below. You can freely select by combining the installation space, installation posture, andoperation method. However, there are some models where the installation position of the micrometer knob cannot be changed due to the product structure.
■There may be cases where the upper and lower tables are deformed due to differences in the flatness of the installation surface. Deformation of the table surface causes backlash, loosening due to failure to obtain the specifiedpreload, and poor sliding due to excessive preload. Therefore, it is recommended to maintain the flatness of the installation surface at approximately 5 microns.

Usage Method
■Installation Method of X-Axis Positioning Stage
When mounting the positioning stage to the base, basically it is mounted by moving the positioning stage surface. Refer to the following diagram.
The above diagram is for demonstration purpose only. Refer to each catalog or 3D data for detailed shapes and specifications of the positioning stage.
■Mounting Posture
Horizontal, inverted, side-mounted horizontal or side-mounted vertical installation options are available. Other installation methods should be given more attention.
Load capacity and accuracy will change greatly depending on the mounting posture.
○：Same as horizontal load capacity.
△：About 1/3 of the horizontal load capacity is the approximate standard, if the catalog contains the vertical load capacity, it should be given priority.
■Vertical Use of X-Axis Positioning Stage
When using the X-axis positioning stage vertically, pay attention to the feed direction, which should not be in the same direction as gravity.
When using a micrometer knob type positioning stage, note that the positioning stage is reset by extension spring. If the force applied is greater than the spring load, the positioning stage surface may fall. For such occasions, alterations can be used as a solution.
Avoid applying loads that exceed the load carrying range in the vertical direction.

Precautions
■Operating temperature and environment
Recommended operating environment: 10～50℃, 20～70%RH (no condensation)
Accuracy assurance environment: 22±5℃, 20～70％RH (no condensation)
■Guiding mechanism
This positioning stage adopts crossed roller guide as the guiding mechanism. Please refill the lubricant at the right time according to the usage conditions to prevent the life of crossed roller guide from being shortened due to the decrease of lubricant and aging.
■Clamping mechanism
①The clamping mechanism of the positioning stage is fixed by the frictional force generated by the fastening screw, so when the applied external force exceeds the frictional force of the clamping mechanism section, it will cause the positioning stage to move. The user should take appropriate measures to avoid movement of the positioning stage surface during use. If clamping reinforcement is required, disc clamping or opposite clamping can be selected.
②The holding force is the value of the force that keeps the positioning stage surface from moving in the clamped condition. Since the maximum holding force varies with the tightening torque, please ensure a sufficiently large safety factor when designing.
■Feed mechanism
The shape of a positioning stage with a micrometer knob installed as shown in the figure below is generally called the standard type. Free selection is possible by combining the installation space, mounting posture, and operation method. However, due to the structure of the product, there are some models where the installation position of the micrometer knob cannot be changed. For details, refer to the [Alteration] at the bottom of each product page.
■Flatness of the mounting surface
The upper and lower positioning stage surface may be deformed due to the different flatness of its mounting surface. Deformation of the positioning stage surface may result in gaps, looseness due to failure to obtain the specified preload, or poor sliding due to excessive preload. Therefore, it is recommended that the flatness of the mounting surface be kept at about 5 microns.

Frequently asked question (FAQ)
- Question: What does a micrometer knob-type positioning stage with a travel distance of ±XX mean?
- Answer: The travel ±XXmm means how many millimeters can be moved in each direction, left and right or up and down, with the middle of the full travel of the micrometer knob as the base point.
- Question: What is the reset method of the micrometer knob type manual positioning stage? What should be paid attention to in use?
- Answer: The micrometer knob type manual positioning stage is reset by means of an extension spring. If the applied load is greater than the spring load, the positioning stage surface may not reset properly or the spring may be damaged directly, so take care when using it.
- Question: Can the positioning stage be mounted vertically? What should be paid attention to?
- Answer: Yes, it can. However, attention should be paid that the load capacity is about 1/3 of that for horizontal installation; and that the feed direction should not be the same as gravity direction, because if the applied force is greater than the spring load, the positioning stage surface may not be able to support the weight and may fall.
- Question: Can manual positioning stage products be used upside down?
- Answer: All except dovetail products. Dovetail products are strictly forbidden to be used upside down.
- Question: Is it possible to freely assemble the XY type positioning stage without the dimension or travel I want?
- Answer: Yes, it is.
