About this part
What it is and why it is made that way
This is the core of our machining work: the bushings, blocks, brackets and housings that other assemblies are built around. Every bore and every mounting face is machined rather than cast or bought, so the part fits the assembly it is designed for. Small parts are machined in one setup to keep the relationship between the bore and the face.
- Bore and mounting faces machined in the same setup
- Turned and milled on CNC equipment, 3-axis through 5-axis
- H7 / H8 bores and parallel faces to drawing
- Full inspection report issued per batch
