Enables the creation of sharp corners and deep cavities that traditional milling cannot access. |
Fabrication Guidelines for Steel
Estratégia de Tratamento Térmico:
Steel is often machined in an annealed (soft) state, then heat-treated for hardness, and finally ground or hard-turned to finish size. This workflow balances machining speed with part durability.
Controle de Cavacos:
Low carbon steels (like 1018) can be “gummy” and produce long, stringy chips. We use chip-breaking tool geometries and high-pressure coolant to break chips into manageable sizes, preventing bird-nesting.
Surface Protection:
Unlike Aluminum or Stainless, standard steel rusts easily. Parts must be oiled immediately after machining or plated (Zinc, Nickel, Black Oxide) to prevent corrosion during shipping and storage.
Tool Coatings:
We utilize TiCN or AlTiN coated tools to withstand the high heat generated when machining alloy steels, allowing for faster speeds and longer tool life.
