Technical Drawing

Technical Requirements
- Unspecified dimensional tolerances: ±0.05.
- Parallelism between opposing planes: ≤0.03.
- Perpendicularity of each plane to the central axis: ≤0.03.
- Coaxiality of internal and external cylindrical surfaces and the internal taper: ≤Φ0.03.
- R* denotes the grinding-wheel corner radius and is a reference value.
- No pores, spots, inclusions, cracks, damage, uneven surface color or other appearance defects are permitted.
- Surface roughness for all surfaces: 1.6.
- Φ89.17 and Φ84.72 refer to theoretical sharp-point dimensions before filleting.
