Semi-Automatic VMM Machine: QualiVMM Semi 300 Series

Overview: QualiVMM Semi 300 VMM Machine

Qualitest configured the QualiVMM Semi 300 Series to provide dependable, non-contact part verification for modern quality control departments. The equipment integrates a solid granite base, a 505 × 350 mm marble staging table, and a motorized Z-axis with automated focusing. This setup conducts standard 2D and 2.5D optical checks with a resolution of 0.5 μm, assisting technical personnel in preventing eye-strain discrepancies and manual adjustment errors across continuous shifts.

Across active manufacturing schedules, this vision measuring machine holds an accuracy rating of 3 + L/200 μm along its 300 × 200 mm horizontal measurement stage. Thanks to polished travel rods with quick-action clamp mechanisms and software paths ready for contact touch probes, the system helps inspection teams gather repeatable dimensional data without slowing down production flow.

Compliance & Standards

Every unit follows internationally acknowledged metrology verification guidelines to confirm optical measurement accuracy across global supply networks:

• ISO 10360-7: Defines acceptance and periodic verification procedures for coordinate measuring machines fitted with video and optical imaging sensors.
• ISO 14253-1: Supplies standardized decision criteria to determine whether inspected physical dimensions fully conform or fail to conform with technical drawings.
• ISO 14978: Details universal definitions and operational expectations for geometrical product specification (GPS) inspection instruments.
• ASME B89.4.1: Sets evaluation protocols for measuring machine performance, serving as a recognized operational benchmark for facilities worldwide.

Key Features

• Motorized Z-Axis with Automated Focusing: Uses dedicated servo drive motors paired with high-precision linear guides to bring surfaces into focus automatically, preventing operator vision variance from distorting Z-axis measurements.
• Granite Foundation and Upright Column: Built using solid granite components that stay dimensionally stable through room-temperature shifts, giving technicians an unyielding reference base.
• High-Definition Optical Subsystem: Combines a 1/3-inch color digital sensor (1.3 megapixels) with a 6.5× zoom assembly, producing 26× to 172× on-screen display magnification for clean feature detection with minimal optical curvature.
• Programmable 8-Zone Lighting Grid: Incorporates a 4-ring, 8-zone cold-light LED surface illuminator and a parallel contour light, helping you dial in contrast on reflective stampings or dark molded plastic edges.
• Quick-Positioning Worktable System: Features polished guide rods and locking levers across the 300 × 200 mm glass stage, allowing quick part changeovers while maintaining 2 μm measurement repeatability.
• Flexible Sensor Upgrades: Offers a path from purely optical setups to contact touch triggers and 3D iMeasuring software packages when parts require depth and coordinate point gathering.

Product Applications & Operating Environments

The QualiVMM Semi 300 Series handles precision quality auditing across a diverse variety of components:

• Machined Parts: Verifies profiles, slot locations, internal radii, chamfers, and center-to-center distances without physical fixture deflection.
• Sheet Metal Stampings and Laser Profiles: Delivers quick edge recognition on flat components, relying on multi-zone surface and backlight arrays to separate actual part edges from surface glare.
• Molded Rubber and Plastic Pieces: Captures exterior dimensions, internal ribs, and fragile openings without exerting physical touch that could bend softer raw materials.
• Electronics and Micro-Hardware: Inspects lead frames, terminal pins, headers, and precision assemblies using high optical zoom settings.
• Coordinate Touch Probing: Transitions into contact inspection for recessed cavities and 3D geometries when optical line-of-sight is insufficient.

Facility Operating Conditions

To preserve stated accuracy limits (E1x,y = 3 + L/200 μm and E1z = 5 + L/200 μm), install the machine within an indoor, climate-controlled testing lab meeting these parameters:

• Temperature: 20°C ± 2°C (temperature drift under 1°C per hour)
• Relative Humidity: 30% to 80% RH
• Floor Vibration: Less than 0.02 g at frequencies of 15 Hz or below
• Electrical Feed: Compatible with AC 220V (50Hz) or AC 110V (60Hz) connections
