Used CMMs For Sale

All About CMMs

Coordinate measuring machines (CMMs) are versatile, high-precision inspection tools used across various industries where accuracy is critical (e.g., automotive, aerospace, medical devices, manufacturing).

CMM Measurements

CMM equipment can measure a wide range of dimensions and features with high accuracy, powered by a blend of hardware and software.

• Length: Measures the length of objects, including straight lines and curved surfaces.
• Width: Measures the width of objects, including flat surfaces and round objects.
• Height: Measures the height of objects, including flat and curved surfaces.
• Diameter: Measures the diameter of round objects, including cones, cylinders, and spheres.
• Depth: Measures the depth of objects, including holes and recesses.
• Angles: Measures the angles between surfaces, including acute and obtuse angles.
• Position: Measures the position of features relative to a reference point or coordinate system.
• Surface: Measures the shape and profile of surfaces, including curvatures and roughness.

CMM Machine Types

The main types of CMM equipment include:

• Bridge CMMs: These CMMs have a bridge-like structure that spans the measuring area. The probe is attached to a moving carriage that travels along the bridge to measure the part.
• Gantry CMMs: Similar to bridge CMMs, the bridge on Gantry CMMs is supported by vertical columns that move on a fixed base, allowing for a larger measuring volume and higher accuracy.
• Portable CMMs: Smaller and more lightweight, portable CMMs can be moved around the part being measured, making them useful for measuring parts that are too large or too difficult to move to stationary CMM equipment.
• Horizontal Arm CMMs: With a horizontal arm that extends over the part being measured, these are useful for measuring large, heaving parts that are difficult to move.
• Optical CMMs: Using optical sensors such as laser or vision systems, optical CMMs can measure parts without touching them which is ideal for delicate or complex parts.
• 3D Scanning CMMs: These use a probe with a 3D scanner to capture a point cloud of the part being measured. The point cloud can then be used to create a 3D model of the part.
• White Light CMMs: Using white light projection systems to measure parts, white light CMM equipment is ideal for measuring parts with complex geometries and fine details.

Advantages of CMMs

The used CMMs for sale here offer a wide range of powerful advantages:

• High Precision: CMM machines provide precise measurements and can measure dimensions to a precision of a few micrometers.
• Repeatable Measurements: The same part can be measured multiple times with consistent results, which is important for quality control and ensures consistency.
• Speed: Multiple points on a part can be measured simultaneously, allowing faster processing.
• Large Measuring Range: Measures parts of various sizes and shapes, making CMM equipment a versatile tool in the manufacturing and design process.
• Data Collection & Analysis: Can collect large amounts of data quickly and accurately, allowing for faster statistical analysis.
• Non-Contact Measurement: Some coordinate measuring machines use non-contact measurement techniques, such as laser scanning, which is ideal for measuring delicate or soft parts without damaging them.

Quality Control With CMMs

Overall, CMMs are an essential tool in the manufacturing industry’s quality control process because they offer an accurate method of measuring the dimensions and features of manufactured parts. This is critical for ensuring that the parts meet the design specifications and the required tolerances.

Quality control is essential to ensure that the final product meets the customer’s requirements and expectations. CMM equipment achieves this by providing fast and accurate measurement data for each manufactured part.

By using CMM machines for quality control, manufacturers can identify any deviations from the design specifications and make the necessary adjustments to maintain product quality.

The used CMMs for sale here also offer the ability to measure a wide range of geometries, including complex shapes and contours which is essential for manufacturers that produce parts with intricate features like medical devices or aerospace components.

Moreover, CMMs offer a non-destructive and non-contact method of measurement, which is extremely useful for measuring delicate or fragile parts that cannot be measured with traditional measurement tools.
