Rotary blade cut-off machine Qcut 350 A

for composite materialsfor PCBsample

Introduction
The Qcut 350 A is an automatic wet abrasive cut-off machine for samples up to Ø 135 mm. Its Low Contact Cutting (LCC) mode enables gentle, controlled cutting of specimens with varying geometries, sizes and materials. Typical applications include metallography, materialography, mineralogy, composite material preparation (CFC/PMC/MMC) and cutting of electronic components such as PCBs. The enlarged cutting chamber and stainless-steel worktable permit comfortable and flexible handling. Software features such as automatic touch detection, Multi-Position-Process (MPP) and parallel adjustment of the wheel guard during vertical cuts increase reproducibility and throughput.

Product advantages

• Automatic horizontal traverse
• Automatic vertical traverse
• Electronic control of cutting force
• Electronic control of distance
• Electronic cutting force limiter
• Program memory for repeatable processes
• Wide range of clamping tools and systems available
• Right-side opening for long parts

Electronic performance control
The feed rate is reduced automatically when the preset maximum power is reached to protect the drive and cutting components from overload.

Precision cross-feed
The optional automatic cross-feed with series-cut function enables precise parallel cuts. The cross-feed is operated via electronic control and can serve as a feed axis for pot wheel operation.

Pulsed cutting
Variable pulsed cutting mode provides advantages when processing heavy sections or difficult-to-cut materials by reducing thermal and mechanical stress.

Multi-Position-Process (MPP)
MPP allows positioning of multiple specimens on the table and cutting them in one automated sequence. The teach-in function makes setting several cutting positions straightforward and repeatable.

Automatic touch detection
After starting an automated cycle the specimen approaches in rapid traverse and the wheel contacts the sample to initiate cutting with preset parameters, ensuring safe and efficient start of cut.

New dimensions
The enlarged cutting chamber and worktable combined with parallel setting of the wheel guard increase cutting capacity and travel for all axes. The side door and additional opening for long parts provide improved access and handling versatility.

Electronic control
Automatic traverse cutting parameters can be stored and recalled in the electronic control. The display shows manual traverse position and allows altering feed rate, travel and cutting force during automatic cycles.
