Precision Finishing of Automotive Part Bores

Some of our most successful single-pass applications include:

• Brake Cylinders
• Anti-Lock Brakes
• Power Steering Components
• Transmission Gears
• VCT Housing, Rotor and Rotor Sub-Assemblies

The Engis Precision Honing Process Development Lab offers to prototype the process and finish your components so that you can evaluate the benefits of the Engis system first hand.  

Furthermore, Engis Electrogrip® grinding wheels are utilized in a variety of grinding applications including finishing gear profiles and other precision transmission components.

For lapping and polishing of your critical automotive parts, we engineer a complete system that elevates both precision and performance at a reduced cost per piece.

Challenge: 

• Inconsistent bore geometry
• High down-time
• High perishable tool cost
  
  

Engis Advantage:

• Improved quality: Cpk >2
• Improved bore roundness to better than 5um for the crank
  bore and 3um for pin bore
• Improved "Bend and Twist"
• Production Rate: 300 parts per hour
• Total perishable tooling cost for finishing both bores is
  roughly $0.03.
• Quick change-over between part types
• Pin and crank bores finished together in the same machine
