The best kept secret in linear motion and positioning

Precision positioning tables

The Mechatronics Series was developed through the integration of precision machining technology and electronics. Precision positioning tables (commonly known as PPT in the UK) incorporate a linear motion rolling guide and ball screw or linear motor between the bed and slide table.

A wide range of products are available in either the module type or super high-precision type. They play an important role in a variety of industries that require equipment with positioning mechanisms such as semiconductor manufacturing equipment, flat panel display manufacturing equipment, and other precision equipment needs. Having the precision positioning table in place helps reduce assemble time.

Ball screw driven units

TU Series is a compact and slim type positioning table, consisting of a U-shaped track rail and a slide table. The slide table, assembled inside the U-shaped track rail, is an integral part of a linear motion rolling guide mechanism, in which two rows of large diameter steel balls are arranged in four point contact with raceways. Owing to this design, stable high accuracy and high rigidity are obtained in operations even under fluctuating load varying in direction and magnitude, and complex load. Also, by adopting a U-shaped track rail, the rigidity of track rail under moment load and torsion is greatly improved.

TU Series includes six sizes with a track rail width of 25mm to 130mm. For each of them, slide table length can be selected. Also, ball screw types and leads, motor types, and sensor installations, etc, can be selected to obtain an optimum positioning table suitable for each application.

TE Series is a lightweight and compact positioning table using high-strength aluminium alloy for its main components, with a slide table assembled inside a

U-shaped bed. A precision ball screw is used for the feeding mechanism, enabling high-reliability and high-precision positioning. Lubrication part C-Lube is built into the linear motion rolling guide and ball screw, achieving long term maintenance free performance and reducing lubrication work. Various specifications such as ball screw lead, motor type and sensor mounting can be configured, enabling the optimum positioning table to be configured according to the application. It is ideal for a wide range of applications ranging from equipment that requires high positioning accuracy such as parts machining, assembly, inspection and conveying equipment through general conveying fields.

TC···E Series is optimal for use in high cleanliness environments for semiconductor and LCD manufacturing machines. The unique high-airtight structure seals the driving part and guiding parts of the slide table, and prevents dust generation around the table. IKO Cleanroom Precision Positioning Table TC···E achieves cleanliness class 3 by enhancing the airtightness inside the table.

TM Series is an extremely compact precision positioning table incorporating a precision ground ball screw with a thread diameter of 2mm, pitch down to 0.5mm, and an IKO Micro Linear Way L with a track rail width of 2mm, well-established in the field of ultra-small equipment.

Linear motion tables

LT Series are lightweight, direct drive positioning mechanisms with low sectional heights. An AC servomotor and miniature optical linear scale are integrated within a high-strength aluminium table and bed to achieve fast acceleration and highly responsive positioning.

A C-shaped magnet yoke set between two stator magnets, along with a high-density coil, enable up to 20G acceleration and deceleration, and a driving force of 150 to 900N for fast, precise motion. The three styles of the LT series are: compact (CE), long stroke (LD) and high thrust (H). Built-in C-Lube lubrication units guarantee long life and maintenance-free operation for five years or 20,000km.

Nano Linear Tables or NT table are ultra-compact positioning mechanisms featuring linear motors and high-resolution encoders for accurate and responsive motion, and high-carbon steel tables and beds for extra stability. High-performance neodymium magnets enable maximum thrust of 70N in a tiny package. Applications include semiconductor equipment, inspection instruments and assembly equipment that require clean environments. The four styles of NT are Standard models (NT…V),

High Accuracy models (NT…H), Pick and Place models (NT…XZ), and High Thrust Pick and Place models (NT…XZH). Built-in C-Lube lubrication units guarantee long life and maintenance-free operation for five years or 20,000 km.
