Internal diameter (ID) grinding. This precision machining process is essential for achieving accurate dimensions and surface finishes on the inside of your cylindrical or conical workpieces. Whether you’re working with aerospace components, bearings, assemblies, or other intricate parts, ID grinding plays a crucial role.

• Internal grinding is the primary process used to precisely finish internal surfaces or bores.
• It involves removing material from the inside of a cylindrical or conical workpiece to achieve the desired dimensions, positioning, and surface quality.
• The internal features being ground can range from simple cylindrical surfaces to more complex profiles required for applications like fuel delivery, compressed air passages, and high-pressure hydraulic systems.
• Aerospace, defense, and commercial assemblies that require rotating components to fit precisely and spin at high speeds with little to no vibration require the close tolerances that ID grinding can achieve.

• ID grinding ensures tight tolerance control and precision.
• The workpiece is held in a chuck or fixture and rotated while the grinding wheel moves in and out of the ID to remove material.
• Typical tolerances achieved include:
  *Inside part diameters: From 0.275″ to 12″ (7 to 304.8 mm)
  *Outside part diameters: Up to 13.7″ (347.98 mm)
  *Parts heights: Up to 24″ (609.6 mm)
  *Roundness: 0.000025″ (0.0006 mm)
  *Close tolerance ± .000050″ (0.0013 mm)

ID grinding is used for various aerospace parts, including:

• Bearings, bushings, and races
• Aerospace components
• Compressor wheels
• Mounting Flanges
• Hydraulic Housings
• Seals
• Nozzles

• Rigorous quality control standards are maintained throughout the grinding process.
• Dimensional measurements, surface finish, and other tests ensure compliance with required specifications.
• Inspection documentations is included with each shipment
