 |
| Characteristic |
●Composed of moving rails with 2 V-groove surfaces harden finish, ground precisely,and roller bearings which are connective and take turns moving in 90 degrees to meet requirement of high parallism and high flatness.In structure, V-groove and crossed roller acquire movement in high accuracy and capacity by linear transmission to act a high precision movement and load capacity performance.
|
●Slide way and body is in one unit, and Gothic arc-groove ground precisely to meet requirement of high parallism and high flatness.Gothic arc-groove formed by dual arc-grooves individually on upper and lower rails of body. Ball moving in single groove is structured by 2 point-contact, and total 4 contact point in dual arc-groove to form strong rail construction. In case of rails of SUS-STAGE is to set ball assembly in arc-groove to save traditional adjustment and revision time. In addition, without adjustment screw would save accuracy problem and maintenance time caused by loosen screw, and cheaper as well.

●Dovetail plane - pinion and rack (Main material：Brass or Aluminum alloy) SFT supply proper models suitable for equipped to various modules such as small, rough-vibrate, large size for installation. Driven-adjustment mode is rack and pinion. Apply to higher working frequency, requirement of faster movement and large stroke.
●Screw-driven plan (main meterial : brass) Prepared by easy-carry standard and slide mode is screw shaft mode. Apply to lower frequency, fine tuning environment.

- Mini-Stage is applied for high precision or mid and heavy loading of various production machinery , testing device , precise positioning and quantitative movement .
- There're many types of mini-stages with single axis (X-axis) ; dual axes (XY-axis ) ; Z-axis ; θ-axis , ρ-axis ...can be collocated as needed .
- Customer's requirements of precise fine tuning ; quantitative movement and able to proceed mass feed of fine tuning.
- Coordinated customer's precise machinery or instrument and fixed in suitable position.
- Feeding mode diversification such as coarse moving handle / micrometer head ; feed screw , rank and pinion with scale and able to manage movement rate.
- The sets of mini stages , XY-axis , XYZ-axis , XZ-axis , and multi-axis modules are able to effectively reduce assembling process because of adjusting their vertical angle before shipping.
- SFT product series are all composed of part in high accuracy , please avoid environment of extreme high temperature , extreme low temperature , huge temperature variation , exposed to sun light , high humidity , high dust , high vibration , high shock and easy-dewed...etc .
- To maintain motion accuracy and usage life of products in all series , please check allowable capacity of the product before operation . Don't overload out of rated capacity .
- Besides allowable capacity limit , please avoid taking gravity of loaded object over the edge of the stage .
- All kinds of rolling mechanisms set in the product need proper clean and lubricated maintenance in the period of operating , depending on situations of operation , and use appropriate lubricant .
- All kinds of rolling mechanisms set in the product are adjusted and leveled by engineers before shipment , please do not try any adjustment if not trained or authorized .
- Please use right lock unit , tools and wrench torque while processing products in positioning security and connecting security .
- For accessories of SFT product series or related information , SFT sales could offer best consultation .
