Double-Sided Lapping
Double-Sided Machining is the most desirable choice when processing
is required on both sides of a part, or when there is a need for precise
thickness, parallelism or flatness on both sides of the part.
Listed below are some typical applications.
Precision Computer Components
Gage Blocks
Precision Spacers
Slitter Knives and Spacers
Thin, Brittle Materials
Bimetal Pump Swash / Wear Plates
Cutting Inserts
Precision Piston Rings
Automotive Sensing Devices
Hydraulic Gear Pump Components
Single-Sided Lapping
Single-Sided high speed lapping allows a competitive alternative
to grinding with better finished part quality.
Listed below are listed some typical applications that are ideally suited to
lapping.
First surface referencing for subsequent operations
Small, thin or "hard to hold" pieces
Fuel injector components
Any sealing face/surface
Gear and rotary pumps
Slitter knives and spacers
Valve plates and bodies
Ceramic, glass, powdered metal, Metal injection molding, carbide, titanium,
molybdenum, stainless steel, Inconel and other hard to machine materials.
Hard coat anodized surfaces
Extrusion, CNC and screw machine "cut off" sizing
Precision Fine-Grinding
Precision Grinding
Flat Honing
Precision Fine-Grinding (also called flat honing) is a relatively new
process, having been introduced in the late 1980's. This process achieves a
superior surface finish when compared to conventional grinding, but also
provides faster stock removal than traditional lapping processes. This type
of finishing is best suited to products requiring a high stock-removal rate,
but where traditional grinding would provide too rough a surface finish, or
where precise tolerances are required. Listed below are typical applications
for precision fine-grinding.
Metal Injection Molded parts
Powdered Metal (Sintered) parts
Seals
Valve Components
Carbides and Cutting Inserts
Precision Piston Rings
Automotive sensing devices
Hydraulic Gear Pump Components
Polishing
Polishing is the most desirable choice when a superior surface finish is
required. Surface finishes can be achieved that are superior to any other
method. Listed below are some typical applications for polishing.
Precision Computer Components
Silicon Wafers
Optical Components
Static and Dynamic Sealing Components
