ZOLIX CXP20-60 and CXPF20-60 High-Precision Compact Electric Linear Translation Stages

Overview

The ZOLIX CXP20-60 and CXPF20-60 are compact, high-precision motorized linear translation stages engineered for demanding optical alignment, micro-positioning, and automated instrumentation applications where space constraints, repeatability, and mechanical stability are critical. Based on the fundamental principle of precision screw-driven linear motion coupled with low-friction crossed roller bearing guidance, these stages deliver deterministic displacement control with sub-micron resolution capability under optimized drive conditions. Designed specifically for integration into OEM optical benches, confocal systems, fiber alignment platforms, and semiconductor metrology tools, the CXP series prioritizes dimensional efficiency (60 × 60 mm top plate, 0.58 kg mass) without compromising structural rigidity or kinematic fidelity. The CXPF variant extends performance into higher-speed regimes through a 2 mm lead ball screw and upgraded crossed roller rail geometry—enabling improved dynamic response while maintaining ≤±1 µm repeatability across 20 mm travel. Both variants employ C3-grade imported ball screws and precision-ground aluminum housing with black anodized finish for wear resistance, thermal stability, and ESD-safe operation in cleanroom-compatible environments.

Key Features

• Compact form factor (60 × 60 mm platform, 20 mm travel) optimized for multi-axis stacking and confined optical layouts
• Crossed roller bearing guide system ensures high load capacity (up to 8 kg horizontal), minimal elastic deformation, and long-term wear resistance
• C3-graded ball screw transmission: 1 mm pitch (CXP) for ultra-fine positioning; 2 mm pitch (CXPF) for enhanced velocity (20 mm/s no-load max) and stiffness
• Five-phase 28-step stepper motor (Oriental Motor PKP523N12B-L) with 0.72° step angle, 52.5 mN·m holding torque, and rated current of 1.2 A
• Integrated sensor suite: dual OMRON EE-SX4320 limit switches (NPN open-collector, DC 5–24 V) and one home sensor for deterministic homing and overtravel protection
• Precision-machined mounting surfaces ensure parallelism ≤0.05 mm and motion straightness ≤10 µm over full stroke
• Modular cabling architecture with 10-pin industrial connector and 0.2 m high-flex shielded cable for reduced electromagnetic interference and simplified maintenance
• Rated moment load capacity of ≥9.3 N·m about all axes supports cantilevered payloads common in lens or detector mounting configurations

Sample Compatibility & Compliance

These translation stages are compatible with standard optical components including mirrors (up to Ø50 mm), kinematic mounts, fiber collimators, and photodetectors. Their lightweight yet rigid construction enables stable mounting on breadboards, optical tables, and custom mechanical frames without inducing significant parasitic vibration modes. While not certified to ISO 9001 or ISO 14001 at the unit level, ZOLIX manufacturing processes comply with GB/T 19001–2016 (equivalent to ISO 9001:2015) and GB/T 24001–2016 (ISO 14001:2015). The stages meet RoHS Directive 2011/65/EU requirements for hazardous substance restrictions. Electrical interfaces conform to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for industrial environments. Mechanical specifications—including backlash ≤1 µm, repeatability ≤±1 µm, and angular deviations ≤30″—are verified per ISO 230-2:2014 (Test Code for Determining the Accuracy of Positioning Numerically Controlled Machine Tools).

Software & Data Management

The CXP/CXPF stages operate as standalone motion modules requiring external controller integration. They are fully compatible with ZOLIX’s MC600 and SC300 motion controllers, as well as third-party systems supporting standard 10-pin TTL/step-direction signaling (e.g., National Instruments PCIe-7358, Thorlabs KDC101, or Raspberry Pi-based stepper drivers with appropriate opto-isolation). When paired with ZOLIX’s TMC-series controllers, microstep resolution achieves ≤1 µm (200× subdivision), enabling closed-loop-like behavior in open-loop configurations. All controllers support ASCII command protocols for scripting via Python, LabVIEW, or MATLAB, facilitating automated calibration routines, multi-stage synchronization, and audit-trail logging compliant with GLP/GMP documentation frameworks. Sensor outputs provide real-time status feedback for safety interlocks and position validation in regulated environments.

Applications

• Precision optical path alignment in interferometers, spectrometers, and laser cavity tuning systems
• Fiber-to-chip coupling and photonic integrated circuit (PIC) testing setups
• Automated wafer inspection stages requiring high cycle life (>10⁶ cycles) and nanometer-level reproducibility
• Confocal microscopy Z-axis fine-focus mechanisms and XY scanning subassemblies
• Miniaturized beam steering assemblies in free-space quantum optics experiments
• Calibration fixtures for coordinate measuring machines (CMMs) and vision-based metrology systems
• Education and research labs where modular, cost-effective, and repeatable motion solutions are required

FAQ

What is the difference between CXP and CXPF series?
The CXP series uses a 1 mm pitch ball screw for superior resolution and finer control, while the CXPF series employs a 2 mm pitch screw and reinforced crossed roller rails to achieve higher speed and greater torsional rigidity—ideal for applications requiring rapid repositioning without sacrificing accuracy.
Can these stages be used in vacuum environments?
Standard units are not vacuum-rated due to lubrication and outgassing characteristics of the crossed roller bearings and motor windings; however, vacuum-compatible variants (with dry-film lubricants and modified motor insulation) can be supplied upon request with lead-time adjustment.
Is encoder feedback available?
No built-in encoder is included; position verification relies on open-loop stepper control. However, external linear encoders (e.g., Renishaw RESOLUTE™) may be retrofitted using the stage’s standardized mounting holes and compatible signal conditioning hardware.
What controller is recommended for achieving ≤1 µm microstep resolution?
ZOLIX TMC-series controllers are required to achieve ≤1 µm effective resolution; MC600 and SC300 controllers yield ≤5 µm under identical microstepping conditions.
Are CAD models and dimensional drawings available?
Yes—STEP, IGES, and PDF mechanical drawings are provided free of charge upon quotation request and include all critical GD&T callouts per ASME Y14.5–2018 standards.
