Heesemann "MFA Impression" Widebelt Sander (2020)

Since 1933, Heesemann has been building superior quality sanders built to withstand the highest production needs.  Heesemann sanding machines are proudly designed and built to the highest standards in Bad Oeyenhausen, Germany. It is not only the superior quality, but the continuous innovation and forward thinking which has set Heesemann apart as the worldwide leader in sanding technology. Heesemann has continued to make technology breakthroughs in the sanding industry which have defined sanding as we know it, including the likes of the first profile sander, the pressure segment belt (chevron belt), the cross-belt sanding unit, and the magnetic segmented pad system CSD®.  With over 120 patents registered and counting, you can be assured that you are getting the best.

Heavy Duty Conveyor Drive with Dual Side Tracking

• Frequency controlled variable speed drive system for variable conveyor speed
• Heavy duty gearbox drives for withstanding heavy sanding applications
• Robust conveyor bed, robotically welded with internal webbing for highest performance
• Large diameter, precision machined and balanced drive rollers for optimal tracking
• Dual side belt tracking for handling heavy loads, high speeds or continuous operation

Single Piece Profiled Transport Belt

High Performance Vacuum Hold Down

Equipped with a high-performance vacuum hold down system for safe movement of workpieces shorter than 500 mm (19.7") in feed direction.  Heesemann’ s unique frame design integrates rigid vacuum plenums for maximum vacuum hold down force over the entire surface of the conveyor bed.  The plenum design eliminates hoses that are traditionally found on vacuum hold down systems. 

Vacuum table design is fabricated to evacuate dust and prevent clogging in order to maximize vacuum suction – producing the strongest vacuum hold down in the industry.  Heesemann vacuum beds also include integrated clean out ports for easy access and cleaning if required after years of heavy usage.

Variable Vacuum Control

Variable vacuum control utilizes a frequency drive to adjust vacuum suction via machine control based upon workpiece parameters or sanding requirements

Belt Manager Software

Software tracks belt usage (left to right) according to how parts are fed into machine and also tracks sq. meters sanded per head.  Each head can have a value entered to notify the operator when the value (in sq. meters) has been met, indicating when to change abrasives.  Values can be freely set according to grit, application, or operation and can be used to quantitatively determine when to change abrasive belts.  This feature helps maximize belt life and sanding consistency.

CSD® - Segmented Pad System

Heesemann’s patented CSD® electro-magnetic segmented pad system delivers the most sensitive sanding system available on the market.  With an interlocking design for consistent sanding of irregular shaped work-pieces, and dynamic control, you can precisely control how the workpiece is sanded, from edges, to cutouts, to frames, you can always maintain crisp edges and prevent burning through sensitive materials such as veneer or sealer.  Heesemann's CSD segmented pad system also includes:

• 100% dynamic control via stepless magnetic segments – pressure is applied smoothly based on surface area being sanded and independent of compressed air source
• Maintenance-free magnetic coils for consistent, maintenance free sanding
• A sealed enclosure keeps dust and other particles out of pressure beam
• Precise surface pressure control allows for a consistent finish
• Precise edge pressure control so the work-piece is sanded consistently and evenly
• Edge pressure controls are independent from work-piece surface pressure
• Pressures that are stored and controlled in IPC for completely customizable and repeatable sanding results
• Multi-track control of edge pressures
• Three (3) rollers per segment
• Non-mechanical, magnetic switches activate the segmented pads eliminating moving parts
• Thickness compensation; 2 mm within and 2 mm between work-pieces (+/- 1mm) without any pressure variation
• Adjustable sanding start/stop that can be administered from the controller
• Interlocking phenolic segments for absolute consistent sanding results

Segmented Rotary Air Jet Cleaning

Rotating compressed air nozzles for blasting workpiece surface.  Nozzles are a non-contact cleaning system which cleans both flat and profiled surfaces without touching the workpiece.
