770MX Machine Specifications

Performance Expectations

Each machine ships with a Certificate of Inspection, which details quality assurance measurements performed by members of our quality assurance team prior to shipping.

Cutting Performance

This machine is capable of cutting a wide variety of materials (for information, see Intended Use) at or near their recommended feeds and speeds. Make sure that your workpiece is held as rigidly as possible and use the most rigid tooling available for roughing cuts. Verify that the programmed operations do not exceed the available spindle power.

Spindle Speed Range 

Two speed ranges are available: 

• Low 175 rpm to 3250 rpm

• High 525 rpm to 10,000 rpm

• Spindle Power Rating 1.5 hp (1.1 kW)

• Maximum Feed Rate 

  • X- and Y-Axis 300 IPM (7.6 m/min)

  • Z-Axis 230 IPM (5.8 m/min)

Resolution and Accuracy

Accuracy is heavily influenced by the techniques that the machinist uses. A skilled machinist can deliver accuracy that exceeds the specified accuracy from the manufacturer; an inexperienced machinist may have difficulty delivering the specified accuracy. We can't predict operator accuracy, but the specified accuracy is an important reference point.

Resolution 0.0001"

NOTE: The resolution of motion is the minimum discrete positional move.

• Ball Screw Positional Accuracy ≤ 0.0006 in./ft

• Positional Accuracy ≤ 0.0013 in./ft

NOTE: The positional accuracy includes additional contributing factors (like compressibility of bearings, ball screw windup, and friction).
