High-accuracy contour measuring machine with exciting new features

Continuous top-bottom measurement function for easy measurement of upper and lower surface.  

Upper and lower surfaces can be measured continuously by using Mitutoyo’s double-sided conical stylus.

Continuous top-bottom measurement allows hassle-free one step calibration

This continuous measurement data can be used to facilitate analysis of features that were difficult to measure before, such as the effective diameter of an internal screw-thread.

The one-step calibration kit supplied with the CV-4500 Series has been upgraded to enable easy calibration of the double-ended conical stylus featuring a contact on both the top and the bottom. Precise work such as calibrating the Z1-axis gain, symmetry, and stylus radius can now be carried out in a single operation.

Variable measuring force function

The measuring force can be varied in 5 steps by using the software provided (FORMTRACEPAK), eliminating the need to adjust the measuring force by switching weights or through positional adjustment.

The CV-4500 Series can also maintain the specified measuring force even when tilted.

Best in class displacement accuracy

The CV-4500 Series features a built-in precision arc scale on the Z1 axis (detector) that allows the arc trajectory of the stylus tip to be read directly, minimizing the detector mechanism error and enabling precision, high-resolution measurement. On the X axis (driver) is a linear scale, allowing high-accuracy full-stroke measurement.

X axis (drive unit): 80mm/s (MAX)

Z2 axis (column): 30mm/s (MAX)

The total measurement time can be shortened by speeding up the traverse movements.

Accuracy

 Z1 axis (detector unit): ± (0.8 + | 2H | /100) μm

H = Measurement height from the horizontal position (mm)

X axis (drive unit): ± (0.8+0.01L) µm *1

L = drive length (mm)

Resolution

 Z1 axis (detector unit): 0.02µm

 X axis (drive unit): 0.05µm

Fast transverse improves measurement efficiency

X axis (drive unit): 80mm/s (MAX)

Z2 axis (column): 30mm/s (MAX)

The total measurement time can be shortened by speeding up the traverse movements.

New top-bottom continuous measurement and variable measuring force enable efficient, highly accurate measurement of a wide range of objects.

Detector with new arm design

Expands measurement range while reducing workpiece interference Mitutoyo’s newly designed detector arm lowers workpiece interference while expanding the measurement range in the Z1 axis (detector).

One-touch arm attachment (Patent pending in Japan). The arm mount uses a magnetic joint for quick and easy arm replacement. The mount also includes a safety mechanism.

All detector and drive unit cables are housed inside the main unit to eliminate any risk of abrasion and guarantee trouble free, high-speed operation.

Auto stop feature assures safety even during high-speed movement

The detector includes a safety mechanism (auto stop upon collision) to assure measurement safety even during high-speed movement. If the arm is removed or shifts during measurement, the safety mechanism is triggered and stops the machine.

Excellent operability

Remote-control unit enables safe, easy & fast measurement

The remote-control unit lets you move quickly from positioning to measurement. The unit also features an emergency stop switch and speed control knob for added safety while the machine is moving at high speeds.

Remarkable Ease of Operation

Incorporation of an ABS scale in the Z2 axis eliminates the need for wearisome origin point re-setting conventionally required for every step of repeated measurements over stepped or multiple sections

Simple positioning by fine feed mechanisms

Small holes and inclined planes can be efficiently measured using the inclined X-axis drive unit and fine-feed handles on the X and Z2 axes.

Simplified CNC function

With the support for a wide range of optional peripherals designed for use with the CNC Form Measuring Unit enables simplified CNC measurement.
