Performance and Cutting Ability

The following table summarizes the cutting performance envelope of the PCNC 440 mill:

Spindle Speed Range 300-10,000 RPM
Spindle Power Rating 3/4 hp (600 W)
Feed Rate Range

0-135 IPM (X, Y)

0-110 IPM (Z)

The PCNC 440 is capable of cutting any material that can be cut with a rotating cutter at or near its recommended feeds and speeds. As with any machine tool, care should be exercised so that programmed cuts do not exceed the maximum available spindle horsepower. Small diameter cutters may perform better with use of a companion spindle or RPM multiplier.

Resolution, Accuracy, and Repeatability

The following table summarizes resolution, accuracy, and repeatability of the PCNC 440 as delivered.

Resolution of Motion (minimum discrete positional move) 0.0001”
Positional Accuracy ≤ 0.0016” per 10”

SAFETY

  • Always wear approved safety glasses or face shield while operating the equipment.
  • Before operating equipment, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair.
  • Non-slip footwear or anti-skid floor strips are recommended.
  • Closed toe shoes are required when working in a shop area.
  • Do not wear gloves while operating the equipment.
  • Make all machine adjustments or maintenance with the machine unplugged from the power source.
  • The automation inherent in a CNC machine presents added risk not present in a manual machine.
  • Understand CNC machines are automatically controlled and may start at any time.
  • Do not leave machine unattended during operation.
  • Always power off machine when not in use.
  • Never operate with unbalanced tooling or spindle fixtures.
  • Remove all tools (wrenches, chuck keys, etc.) from spindle and machine surface before starting operations; loose items can become dangerous projectiles.
  • Use adequate work clamping; loose workpieces can become dangerous projectiles.
  • Protect your hands. Stop machine spindle and ensure machine motion has stopped before:

- Reaching into any part of the machine motion envelope

- Changing tools, parts or adjusting the workpiece

- Changing belt/pulley position

- Clearing away chips, oil or coolant; always use a chip scraper or brush

- Making an adjustment to part, fixture, coolant nozzle or when taking measurements

- Removing protective shields or safeguards; never reach around a guard

  • Keep work area clear of clutter as machine motion can occur when keys are accidently pressed or objects fall on keyboard, resulting in unexpected motion.
  • Position clamping attachments clear of tool path. Be aware of workpiece cutoffs that could be cut free during operations and become dangerous projectiles.
  • Always use proper feeds/speeds, as well as depth/width of cut to prevent tool breakage.
  • Check for damaged tools/workpieces and cease operations if detected; replace before re-starting operations as these can become dangerous projectiles. Never use longer or larger tools than necessary.
  • Chips and dust from certain materials (e.g., magnesium) can be flammable. Fine dust from normally non-flammable materials may be flammable or even explosive.
  • Chips, dust, and vapors from certain materials can be toxic. Always check the Materials Safety Data Sheet (MSDS) for each material.
