Renishaw, the world's leading manufacturer of measurement products, has introduced a new range of gratings for linear axis position feedback – the new gratings have extremely tight mounting tolerances and operate at speeds up to 24 m/s. QUANTiCTM grating series can be output directly from the readhead Digital signals, no need to use extra large external interfaces. This breakthrough innovation was first applied to Renishaw's advanced VIONiCTM gratings.

For OEM machine manufacturers, it is important to match the customer's delivery time, so if the installation and commissioning time of the internal components of the machine (such as grating) can be shortened, it will help to ensure that the product is delivered on schedule, thus improving the operating profit. QUANTiC grating This is taken into account in the design: it has the most relaxed installation tolerances and excellent anti-fouling properties of Renishaw's history, and is available as an advanced diagnostic tool for remote calibration and fault diagnosis (Advanced Diagnostic Tool, ADT) ).
QUANTiC readhead on the scale
The QUANTiC encoder system is equipped with a 40 μm pitch scale; with Renishaw's unique optical filter system design, QUANTiC allows for tighter mounting tolerances and higher operating speeds. For example, the readhead mounting clearance and the torsion tolerance are currently respectively Up to ±0.2 mm and ±0.90. Optional scales include rail-mounted (FASTRACKTM) RTLC40 scales and self-adhesive RTLC40-S scales: both ensure that the scale is independent of the mounting substrate and independent Expansion or contraction, which simplifies the error compensation process.
The QUANTiC encoder system has a variety of advanced design features, so it is extremely dust and dirt resistant. The QUANTiC readhead integrates Renishaw's proven optical filtering system to average the readings of multiple scale cycles, effectively filtering Aperiodic features caused by dirt, etc. The accuracy of the measurement signal can be further enhanced by a series of electronic signal processing algorithms such as automatic gain control (AGC), automatic offset control (AOC) and automatic balance control (ABC). With the new detector design, the QUANTiC encoder also features a third layer of signal filtering, which helps to better eliminate the frequency of non-harmonic signals due to scale contamination. All these signal conditioning functions are combined. It ensures that QUANTiC achieves extremely low electronic subdivision error (SDE) and minimizes signal fluctuations due to contamination.
QUANTiC readhead
The Advanced Diagnostic Tool (ADT) consists of ADTi-100 hardware and ADT View software, making the raster installation and calibration process extremely simple and easy. Features and benefits include: remote monitoring; signal strength audiovisual indication, limit switches and readhead tilt Indication; DRO output, Lissajous output, and the ability to save data in a variety of common file formats.
QUANTiC gratings help to increase the productivity of large-scale production lines, enabling OEM customers to save time and cost. The QUANTiC grating series has been CE certified and manufactured by Renishaw in strict accordance with the ISO 9001:2008 certified quality control system. Like all Renishaw grating products, QUANTiC is supported by a global team to provide truly fast global service.
