Kemet composite lapping plates are manufactured from a homogeneous mixture of synthetic resins, metal particles and other materials. The plates are ideal for today's advanced lapping technology, especially when used with Kemet Liquid Diamond.

Standard Kemet Lapping Plates are normally supplied mounted on a cast iron backing plate for maximum stability. They are recommended for general and heavy-duty work where high precision flatness and surface finish are required.

Features

• Holds diamond particles firmly, ensuring both efficient stock removal and repetitive component surface finish.
• Ductile qualities cushion the diamond particles, preventing damage to the workpiece.
• Produced in varying hardness values so that even the softest material can, without impregnation, be safely lapped with diamond particles.
• Dissipates heat and prevents laminar flow of lapped surfaces
• Easy control for optimum flatness
• Lapping/polishing plates available to fit all makes of lapping machines with plate diameters up to 3000mm
• Supplied with a cast iron backing plate for maximum stability.

Kemet Iron Lapping Plates

The most commonly used lapping plate. For general purpose stock removal and lapping applications. Excellent for stock removal and pre-polishing operations

Kemet XP Lapping Plates

Gives improved flat polished surfaces on many materials. Mirror surfaces can often be produced on harder materials.

Kemet Copper Lapping Plates

Used to lap softer materials where fine lapping and polishing are the primary requirements.

Kemet Tin Lapping Plates

One of the softest Kemet lapping plates used for mirror polishing with fine grades of Kemet Liquid Diamond.

Kemet Ceramic Lapping Plates

One of the hardest Kemet Lapping Plates. Used for special applications often where a cleaner lapping process is required.

We offer a relapping service for Kemet plates that are worn out of flatness.

Kemet FP Plates

A replacement for the Kemet Lead/Tin Plate, the Kemet FP Plate gives good stock removal, whilst producing high quality surface finish and flatness with Kemet Diamond Slurry.

Kemet Lift Off Disc System

Kemet Lapping Plates are also available as Lift Off Discs, for machines up to 610mm (24") diameter.   Discs are supplied mounted on an aluminium backing plate, which locates on to an aluminium drive plate by means of three pegs. Lift Off Discs can be easily changed and are recommended for light duty work where general flatness and precision finish are required.

Grooving

Kemet Lapping Plates can be supplied grooved to suit specific applications.

Kemet Annular Grooved Plates

These plates are designed for precision shoulder lapping of a wide range of parts, such as fuel pump gear faces and pressure relief valve caps. Groove width and depth of plates need to be specified when ordering.

Kemet Portable Hand Lapping Kits

Hand lapping uses the same principles as machine lapping with respect to abrasive grade / plate selection / plate flatness, but with the following exceptions

• Lapping plate is kept stationary
• Components are moved by hand in a figure of 8 action
• Diamond compounds or liquid diamond can be used

Leaking pumps, valves and seals cause many problems, leading to wastage, poor performance, unnecessary costs, even health hazards. Kemet Portable Lapping Kits enable refurbishment to be carried out on site, reducing expensive downtime. Components manufactured from ceramics, tungsten carbide, stellite, brass, steel, silicon carbide, ni-resist etc, can be lapped and/or polished by hand in minutes rather than hours. The kits are also ideal for low volume production, where it is not economical to purchase a lapping or polishing machine.

Kits available:

• Type L Kit for lapping
• Type P Kit for polishing
• 3 Lap Kit for lapping and polishing

Cast Iron Lapping Plates

We offer a wide range of cast iron lapping plates to suit most lapping machines. Available in 15", 24", 36" serratted or solid. Other sizes available on request.

Hand Lapping Plates

Cast iron Hand Lapping Plates, are suitable for laboratory, toolroom or maintenance workshops and can be used for lapping parts to extreme flatness.

Available serrated with a square cross-hatched pattern or solid (unserrated) and in 6", 12" and 18" diameters.

Soft metal alloy polishing plates are used with diamond abrasives to produced polished surfaces on components. Available in 6", 12" and 18" diameters.
