Every machinist knows the importance of chip control and just how easy it is to take for granted when it’s working well. When it isn’t, it can be a real headache until a solution is found. Luckily, there are many options to consider that could help alleviate chip-related issues: helix modifications, chip breakers, using coolant to remove chips, optimizing the geometry for chip load, and many more. Working with a cutting tool manufacturer allows customers to choose the option that works best for the job and materials at hand.
How does this play out?
EXAMPLE 1
Application: COMPANY A is a firearms manufacturer and needs a tool to create a thin-walled slot
Material: Steel
Tool type: Custom form keyseat cutter
Coating: None
MITGI mix:
- Forms on alternating teeth designed to optimize chip load and increase tool life
- Staggered geometry helps to reduce vibration, improve finish, and minimize production inconsistencies
- Dished on both sides to produce clearance and alleviate rubbing or binding
Add-on Request: COMPANY A would like to increase tool life thereby reducing overall project costs
MITGI recommendation: Add more teeth to the form. With more teeth to engage, the tool life will increase resulting in reduced tool quantities over the life of the job.
EXAMPLE 2
Application: COMPANY B specializes in hydraulic components; facing tight time constraints, COMPANY B is creating a tapered form and places high priority on part finish
Material: Aluminum
Tool type: Custom tapered reamer
Coating: None
MITGI mix:
- Ample core to optimize tool strength and rigidity
- Spiral flute with material specific helix to provide efficient chip removal
- Flute geometry and strong cutting edges designed to reduce chatter and improve finish
- Custom rake applied to help avoid the tool grabbing the part
- Geometry designed to alleviate tool pullout from holder
