Types of Lapping Plates
Cross-hatch

Our cross-hatch grooved plates are fully machined to suit individual machines, and are available in sets of upper and lower plates.
The sizes available are 800mm to 2200mm in diameter, at a thickness to meet the machine’s requirements.
silicon wafer, quartz wafer, mechanical parts, optical and ceramic components production.
In order to provide a thorough hardness, to enhance longevity, to improve wafer TTV and to minimise scratch rates, all plates are cast and heat treated.
Grooves are machined at pitches to our specifications or as per our customer’s requirements. All plates have an individual number. This is to provide product traceability and the continuous monitoring of performance.
Radial

Radial grooved plates are made from our martensite material in order to improve life expectancy.
They’re available in plates up to 1000 mm diameter and are supplied for silicon wafer, quartz wafer, mechanical parts, optical and ceramic components production.
Groove pitch is machined on a 4-axis computer controlled machining centre in a controlled environment, as per customer’s requirements.
