GTMA FEATURED COMPANY
Renishaw is a global company with core skills in measurement, motion control, spectroscopy and precision machining. Renishaw generated turnover of £288.8 million and now has over 50 locations in 30 countries, with more than 2,500 employees worldwide.
For machine tool users, probes for CNC machine tools allow automated tool setting, workpiece set-up, in-cycle gauging and part inspection on CNC milling machines, machining centres, CNC lathes and mill-turn machines.
Products available include laser tool setters, contact tool setters, tool breakage detectors, touch probes and high accuracy inspection probes. To check the performance of a CNC machine tool, the Renishaw QC20-W ballbar provides a simple, rapid check of a machine’s positioning performance to recognised international standards.
Our innovative sensors for co-ordinate measuring machines (CMMs) are an industry standard, from basic touch-trigger probes and manual probe heads, through to automated stylus changers, automated probe changers, motorised indexing probe heads, and revolutionary five-axis measurement systems. A full range of probe styli/probe tips is also available.
In motion control Renishaw’s laser encoders, optical linear encoders, optical angle encoders, optical rotary encoders, magnetic rotary encoders, magnetic chip encoders and magnetic linear encoders are used for position feedback applications in industries as diverse as electronics, motor sports, bomb disposal, semi-conductors, food manufacturing and print production. Latest developments include a true absolute, fine-pitch optical encoder system.
To assess, monitor and improve the static and dynamic performance of position-critical motion systems, including CMMs, CNC machine tools, PCB drilling and pick-and-place machinery, our laser interferometer and environmental compensation system offers a linear measurement accuracy of ±0.5 ppm, readings of up to 50 kHz and a linear measurement speed of up to 4 m/s, with a linear resolution of 1nm.
Renishaw has also launched a new gauging product line. The first product is Equator™, a radical new alternative to traditional dedicated gauging, filling a gap in the market never before addressed. The patented low-cost design, unique in construction and method of operation, is capable of high-speed comparative gauging for inspection of high-volume manufactured parts.
Through the acquisition of MTT Technologies, Renishaw now designs, develops and manufactures additive manufacturing and rapid prototyping systems, including selective laser melting, metal casting, and vacuum casting machines and processes.
Renishaw has also entered the advanced materials market, where its subsidiary company Renishaw Advanced Materials Ltd employs three core technologies around which it develops its products: manufacturing advanced Diamond-like Carbon (DLC) coatings, Shape Memory Alloy (SMA) products, and materials demonstrating the Piezo effect.
Renishaw are also a recognised leader in Raman spectroscopy, where our optical spectroscopy products exploit the Raman effect in a non-contact, non-destructive manner, to identify and characterise the chemistry and structure of materials. A diverse range of analytical applications include pharmaceutical, carbon and diamond, material science, gemmology and mineralogy, forensic science, nanotechnology, biomedical and semiconductors. Products include Raman microscopes, compact Raman spectrometers for process monitoring, Raman analysers for scanning electron microscopes, cooled CCD detectors and lasers for spectroscopy.
In the world of dentistry, we are the world’s leading supplier of in-lab dental CAD/CAM systems. Our products include a high-accuracy 3D contact dental scanner, powerful CAD design software, and a unique dental milling system. Dental laboratories can manufacture high quality zirconia frameworks or copings either in-lab, or by using our central manufacturing centre, where we also offer cobalt chrome frameworks.
With an increasing focus on the healthcare sector, we now offer medical devices, surgical robots and planning software for use in stereotactic neurosurgery, for procedures including Deep Brain Stimulation (DBS), Motor Cortex Stimulation (MCS), Stereo Electro-Encephalography (SEEG), neuro-endoscopy, radio-surgery, biopsy, and Transcranial Magnetic Stimulation (TMS).
We have also entered the field of medical diagnostics, with the creation of Renishaw Diagnostics Ltd, which aims to become the premier provider of automated multiplex diagnostic and clinical research systems for fast, reliable and simplified disease detection.
