Actuator Frame Bearing Blank Creation
- Cut blanks that are 1.165 inch x 1.165 inch x .50 inch.
- The final blank will be 1.125 inch x 1.125 inch x .50 inch.
- The size of this part must be precise, use methods and tools that will achieve a clean cut.
- Using the mill size the blanks:
- Place the blank in the vice on a 1 1/8 in spacer. Use a rubber mallet after clamping it down to make sure the piece is sitting evenly on the spacer.
- Use a 1 in endmill. Find the surface of the work by slowly raising the bed until the bottom of the endmill makes contact with the blank.
- The first cut will be 0.02 in below the surface of the work. Set this height on the bed as zero.
- The vice can hold 5 blanks at a time. Push them close together and use the rubber dead blow to fully seat them on the spacer.
- Use the left/right automatic feed and run the mill at high speed.
- Before un-clamping the vice, use a sharp de-burring tool to clean up the edges of the pieces and blow away any chips.
- Check that the dimensions of this cut part are now 1.165 x 1.145 x 0.5 in.
- Cut one side of all the blanks in this way. Then, raise the bed by 0.02 in and cut the opposite side of all the pieces.
- The dimensions should now be 1.165 x 1.125 x 0.5 in, with two parallel machined sides.
- Lower the bed back down to the zero mark and repeat the above steps with the other two sides.
- The final dimensions are 1.125 x 1.125 x 0.5 in.
- Place the pieces back in the vice to deburr the short edges.
