Precision Manufacturing
Our credentials
Taylor Hobson is world renowned as a manufacturer of precision measuring instruments. Used for final inspection in research and production, our equipment performs at nanometric levels of resolution and accuracy.
Our machines
We invest in only the highest precision machine tools produced by leading manufacturers around the world. We then work extensively with the manufacturer to enhance the performance of the machine to better satisfy our unique requirements.
Our people
Taylor Hobson engineers have developed manufacturing skills and processes that push the very limits of precision. They have an intimate understanding of how the design, performance and production.

Surface grinding
Levels of surface grinding precision that for Taylor Hobson are relatively straightforward to attain are often considered specialist by the majority of industry. General straightness in the 2µm range can be achieved on a routine basis with little need for technical support.
Surface grinding capacity and capability:
| Model | Chuck Capacity (length x width) |
Maximum under wheel |
Accuracy |
| ELB SF CNC | 1500mm x 800mm | 800mm | 5µm over chuck area |
| ELB 15 CNC | 1200mm x 350mm | 400mm | 0.25µm over 1000mm |
| ELB 10 NC | 800mm x 450mm | 400mm | 0.5 µm over 600mm |

Cylindrical grinding
High precision cylindrical grinding represents Taylor Hobson’s strongest manufacturing process expertise. We produce the reference datums for our measuring instruments with a combination of geometry, dimension and surface finish control that is amongst the very best in the world.
Cylindrical grinding capacity and capability:
| Model | Length between centers |
Maximum diameter | Maxium weight (centers) |
Straightness accuracy |

Complex machining
Complex machining is critical to many components used in Taylor Hobson’s metrology instruments.
Extremely high dimensional and geometrical tolerances must be machined on a “one hit” basis to ensure that the end structure is highly stable with a high grade cosmetic appearance.
Over the years we have developed the processes, tooling and skills that allow us to routinely achieve these extraordinary results. Our capability was expanded with the acquisition of a Mori Seiki MT2000S Machining Centre. It provides for high precison machining of components in 5 axes.

| Bar capacity spindle 1 | 63mm diameter |
| Bar capacity spindle 2 | 63mm diameter |
| Distance between spindles | 1,000mm |
| Accuracy | 10um |

Diamond turning
Our experience with high precision diamond turning has contributed to a direct improvement in our product specification. The diamond turned air bearing spindles used in Taylor Hobson roundness measuring instruments typically out-perform the 0.02µm radial limit of error specification.

Graticule laboratory
The Taylor Hobson graticule laboratory has the capability to manufacture glass and metal gratings and a range of other components based on deposition and etching technology. We use these components in our own measuring instruments and also undertake sub-contract manufacture for a number of prestigious companies.
Flat lapping
A full range of lapping equipment is available for ferrous and non-ferrous materials. Assessment of flatness by monochromatic light source as well as other techniques is available. Required services for cleaning are also in place.
Precision assembly
Precision assembly is a key Taylor Hobson strength. Our experience in electro-optical-mechanical assembly is instrumental to our success in the metrology industry. The nature of our business dictates that our assembly staff be flexible, highly skilled and able to cope with complex tasks involving multi-stage testing and sign-off.
Diamond turning machines epitomise the melding of technology and craftsmanship at Taylor Hobson. Our expertise at precision assembly provides the Ultraform 250 with performance more likely found in measuring instruments than machine tools.
