Surface Grinding:
Surface grinding is a common grinding operation used to produce flat surfaces on the workpiece. In surface
grinding, the grinding wheel rotates parallel to the workpiece surface, removing material in small increments to
achieve the desired surface finish and dimensional accuracy. Surface grinding is often used to produce precision
flat surfaces, squareness, and parallelism on components such as tooling plates, dies, and molds.
Perform any necessary grinding to achieve the desired surface finish on critical surfaces of the tool.

Assembly:
Before assembly, each component of the blanking tool undergoes thorough inspection to ensure it meets the
required specifications and quality standards. This inspection involves visually examining the components for
any defects, irregularities, or damage that could affect the performance or functionality of the assembled tool.
Additionally, dimensional measurements may be taken to verify that the components are within the specified
tolerances.
Alignment and Fitting:
Proper alignment and fitting of the components are essential for ensuring the blanking tool functions correctly
and efficiently. This involves carefully aligning mating surfaces and features of the components to ensure they fit
together snugly and securely. Precision machining techniques such as lapping, honing, or grinding may be used
to achieve tight tolerances and smooth mating rfaces, facilitating proper assembly and reducing the risk of su
misalignment or premature wear.

SAFETY:
Personal Protective Equipment (PPE):

• Always wear appropriate personal protective equipment (PPE) when working with machinery and tools. This
includes safety glasses or goggles to protect your eyes from flying debris, ear protection to reduce the risk of
hearing damage from loud machinery, and gloves to protect your hands from sharp edges and hot surfaces.
Additionally, wear close-toed shoes with non-slip soles to prevent slips, trips, and falls.
Machine Safety Guards:
• Ensure that all machine safety guards and barriers are in place and functioning correctly before operating
any machinery. Machine guards help prevent accidental contact with moving parts and cutting tools, reducing
the risk of injury. Never remove or bypass machine guards unless necessary for maintenance or repair, and
always follow proper lockout/tagout procedures when servicing machinery.
