The document provides detailed dimension tables for various standard and wide sizes of the MINISCALE PLUS, including system height, width, rail width, and attachment hole spacing. Load capacities are specified with static and dynamic values, along with permissible torques for both lateral and longitudinal directions.
The MINISCALE PLUS is an optical, incremental measuring system comprising a dimensional scale on the guide rail, an optical sensor on the carriage, a flexible sensor print, and an interface module. The system uses a flexible flat cable for dynamic loads, allowing flexible positioning of the interface module.
Specifications and Components:
The MINISCALE PLUS system includes a sensor, interface module, and guideway with a dimensional scale. The sensor detects optical signals from the scale, which are then converted into electrical signals by the interface module. The system actively controls LED illumination to counteract aging and impurities.
Interface Module:
The interface module processes raw signals into standard output signals, available in analog or digital formats. Key components include a ZIF connector, green and red LEDs for status indication, and a compensation key for digital interfaces. Various structural types are available, including options with or without housing and different connectors.
Signal Processing:
Analog signals are differential, with sine and cosine signals shifted by 90° and correlated with the scale markings. Digital signals are differentially interpolated, achieving a resolution of 100 nm. The reference pulse marks a precise position on the scale.
Incremental and Reference Tracks:
The incremental track runs the length of the guideway, with customizable position and length. Reference tracks are added for precise positioning, with standard and special versions available. Reference marks must be synchronized with the dimensional scale.
Interface Module Pin Connections:
Pin connections are detailed for both analog and digital signals, with specific configurations for D-Sub 9 and Micro Match connectors.
Extensions:
An extension kit with a flexible flat cable (FFC) is available for situations where the interface module cannot be mounted directly at the sensor. The FFC cable offers benefits such as reduced system mass and dynamic load capability.
Lubrication:
Lubrication is crucial and should be defined during the design phase. Factors to consider include operating conditions, external influences, and compatibility. Guideways should be kept free of cutting oils or water-soluble coolants.
MINISLIDE Product Overview
Product Characteristics:
The MINISLIDE range includes sizes 4 to 15, with travel distances from 6 to 102 mm. The MS range features a Gothic arc profile for high load capacity and compact form, while the MSQ range offers high speed and acceleration capabilities.
MSQ Product Characteristics:
The MSQ range includes rail widths of 7 to 15 mm, with integrated cage control to prevent cage creep. The design allows for speeds up to 3 m/s and acceleration up to 300 m/s². The robust cage control system ensures high process reliability.
Maximum Rigidity and Load Capacities:
MINISLIDE MSQ products have four tracks with a circular arc profile, arranged to ensure large inner spacings and evenly distributed force from all directions.
MINISLIDE products are designed with zero backlash and high rigidity due to the high number of rolling elements. The MSQ model features a circular arc profile that provides the highest rigidity with minimal deformation. The MS model offers a maximum acceleration of 50 m/s² and a speed of 1 m/s, while the MSQ model can achieve 300 m/s² and 3 m/s. Both models operate within a temperature range of -40°C to +80°C, with the MSQ extending up to +150°C. They are suitable for vacuum environments and cleanrooms up to ISO class 6.
The guideways, carriages, and ball bearings are made from stainless, through-hardened steel. The MS model uses POM for the cage, while the MSQ uses PEEK for both the cage and pinion. The end pieces of the MSQ are also made from PEEK.
The running accuracy and parallelism of supporting surfaces are critical, with specific tolerances based on system length. For example, a system length of 10-30 mm has a straightness tolerance of 3 μm. The total height tolerance and push force are influenced by preload and lubrication.
MINISLIDE products are manufactured to ensure smooth operation with a coefficient of friction of 0.003 under normal conditions.
Detailed tables provide dimensions, load capacities, and permissible torques for various sizes of MS and MSQ models. For instance, the MSQ 9 model has a static load capacity of up to 3341 N and a dynamic load capacity of 1252 N.
Lubrication is a critical design element, with initial lubrication using Klübersynth GE 46-1200. Subsequent lubrication can be done with oil or grease, depending on the application. Custom lubricants are available for specific conditions such as vacuum or cleanroom environments.
Options include defined push force and customer-specific lubrication. Guideways can be cleaned and vacuum-packed for vacuum applications, with packaging suitable for ISO 6 or ISO 7 cleanroom classes.
The performance of MINI-X guideways is optimized when mounted on a rigid structure with high geometric accuracy. Surface inaccuracies can negatively impact accuracy, running behavior, push force, and service life. High surface contact ratio is essential to prevent assembly relaxation, achieved through high surface quality. For high-precision applications, a maximum Ra value of 0.4 is recommended, while standard applications can have a maximum Ra value of 1.6.
Adhering to specified height and corner radii ensures proper force absorption and clearance for carriages. Tables provide maximum values for various rail sizes to ensure correct contact with mounting surfaces.
Permissible deviations for lateral (E1) and longitudinal (E2) alignments are calculated using preload factors and spacing dimensions. Examples illustrate calculations for specific types and preload classes. Flatness and parallelism tolerances are specified to maintain running accuracy and service life.
Alignment methods vary based on accuracy needs, with options ranging from manual alignment to using reference surfaces and lateral clamping for higher accuracy. Installation methods consider load, accuracy, time, and location specifics. Reference surfaces simplify installation and improve accuracy.
Tools required include oil stone, lubricant, torque wrench, and fastening screws. Reference surfaces must be cleaned and lightly oiled. Initial lubrication involves applying suitable oil or grease to guideways and carriages, with specific quantities recommended for different carriage types.
Initial lubrication is necessary as components are delivered unlubricated. Oil or grease lubrication methods are detailed, with relubrication intervals dependent on various factors. Proper lubrication ensures smooth operation and longevity.
Ensure all components are at room temperature before installation. Fastening screws should be tightened with a torque wrench, alternating sides to maintain balance. Protective measures are recommended during carriage transfer to prevent contamination and misalignment.
- Tightening Torques for Fastening Screws: Recommended torque values are provided for oiled screws with a friction coefficient of 0.12. For lubricated screws with a friction coefficient of 0.07, torque values should be halved. A table lists torque values for screws of strength class 12.9 and A2-70 according to DIN 912.
Load Carrying Capacity and Service Life
- Principles: Load capacities are based on DIN 636. Static load capacity C0 is set to prevent deformation affecting bearing operation. Dynamic load capacity C ensures a nominal service life of 100 km. Service life calculations should consider all acting forces and moments.
- Service Life Calculation: Formulas are provided for calculating nominal service life in meters and hours, considering factors like effective load carrying capacity and dynamic equivalent load.
Handling, Storage, and Transport
- Delivered Condition: Guideway components are delivered in protective packaging. MINIRAIL guideways are unlubricated by default, while MINISCALE PLUS and MINISLIDE products are pre-lubricated.
- Handling and Storage: Products should be stored in original packaging, protected from moisture, and handled with care to prevent damage. Temperature guidelines are provided for different products.
