T33008 7-7/8" x 39-3/8" 2-Axis Lathe DRO

Everything you need for a custom digital readout for your lathe.

The T33008 7-7/8" x 39-3/8" 2-Axis Lathe DRO bundles all of the components you could want to add to your lathe.

The highly-reliable and accurate readout features several powerful functions including:

  • PCD Pitch circle diameter function
  • LHOLE Line hole positioning function
  • INCL Inclined machining function
  • SDM 199 subatum memory function
  • Radius function
  • SHRINK Shrinkage calculation function

The aluminum case of the readout is totally sealed to protect the circuitry against dust, fumes, and evaporated coolant. A polyester film offers excellent chemical resistance to most commonly used industry solvents. The components are soldered by computerized soldering machines to achieve high-quality connections. This ensures a lower power consumption and improves reliability.

This kit includes 7-7/8" and 39-3/8" linear optical scales. Their plastic seals offer superior oil resistance, durability, and high elastic recovery properties. The slide carrier uses five P5-grade bearings to achieve smooth and accurate movement.

There are plenty of combinations to choose from.

Like all Grizzly digital readouts, the T33008 comes with a 1-year warranty which covers parts and assures the kit is free from factory defects.

The Grizzly Customer Service and Technical Support Teams are U.S.-based. Parts for the DRO may be available online and shipped from the Grizzly parts warehouse in Springfield, MO.
