5. 材料与切削 (MATERIALS & CUTTING) 17-4 PH (AISI 630) is a martensitic precipitation-hardening stainless steel delivering ultra-high yield strength (up to 1170 MPa) paired with excellent corrosion resistance comparable to 304.
5. 材料与切削 (MATERIALS & CUTTING) Inconel 718 is a precipitation-hardenable nickel-chromium superalloy that maintains exceptional yield, tensile, and creep-rupture strength at extreme operating temperatures up to 700°C (1300°F).
5. 材料与切削 (MATERIALS & CUTTING) C110 (Electrolytic Tough Pitch Copper) offers 100% IACS electrical conductivity and ultra-high thermal dissipation, making it essential for semiconductor heatsinks, power busbars, and EDM electrodes.
5. 材料与切削 (MATERIALS & CUTTING) PEEK-CF30 is an ultra-high performance thermoplastic reinforced with 30% short carbon fibers, providing metal-grade flexural stiffness, low thermal expansion, and extreme wear resistance.
5. 材料与切削 (MATERIALS & CUTTING) Acrylic (Polymethyl Methacrylate / Plexiglass) offers crystal-clear 92% light transmittance, exceptional UV weatherability, and high surface hardness for optical lenses and light guides.
4. 数控与编程 (CNC & G-CODES) M08 turns on the primary flood coolant pump, while M09 turns off all coolant systems. Proper coolant management prevents thermal tool failure, flushes chips, and protects surface finishes.
4. 数控与编程 (CNC & G-CODES) G83 is a canned cycle for deep-hole drilling that repeatedly feeds into the material by an incremental peck depth (Q) and retracts completely to the initial plane (R) to evacuate chips and deliver coolant.
4. 数控与编程 (CNC & G-CODES) G43 activates positive tool length offset compensation, instructing the CNC controller to offset the Z-axis position based on the physical length of the active tool stored in the tool table.
4. 数控与编程 (CNC & G-CODES) G02 (clockwise) and G03 (counter-clockwise) are modal CNC G-codes that command cutting tools to follow circular and helical arcs along defined coordinate planes.
