In the competitive landscape of metal fabrication, the quality of a part’s finish is often what separates a premium supplier from the rest of the pack. While many shops focus on the power of their lasers or the tonnage of their press brakes, the most successful operations understand that deburring, edge rounding, and surface conditioning are where the true value is added.
Revolution Machine Tools (RMT) has partnered with Jonsen, a global leader in sanding and finishing technology, to bring a comprehensive lineup of finishing equipment to the North American market. Jonsen machines are engineered to replace inconsistent manual labor with automated precision, offering distinct advantages over traditional finishing methods.
The Jonsen Finishing Lineup: Precision for Every Application
RMT’s selection of Jonsen equipment covers the entire spectrum of finishing needs, from small-batch manual assistance to high-volume, fully automated production lines.
- Deburring and Edge Rounding (Dry Operation). The Jonsen SGP series (such as the SGP1000) and the SGB series are the workhorses of the deburring world. These machines are specifically designed to handle parts coming off laser, plasma, or waterjet cutters. Unlike simple wide-belt sanders that only hit the “peaks” of a burr, Jonsen’s multi-head configurations utilize planetary abrasive barrels. These barrels rotate in counter-opposing directions, ensuring that every edge—internal and external—is rounded uniformly without thinning the material.
- Wet Operation Systems: Surface Quality and Cooling. For materials like titanium, aluminum, or stainless steel where heat can cause warping or discoloration, Jonsen offers wet systems like the SG630-WJS. These machines use a recirculating coolant system that acts as a lubricant and temperature regulator. This results in a “hairline” or “No. 4” finish that is more delicate and visually consistent than dry sanding. Furthermore, the wet operation captures dust in a sludge, significantly improving shop air quality and safety.
- Specialized Fine Blanking and Small Parts. The Jonsen SD300-JS+D is a specialized solution for small, high-precision parts. Fine blanking and punching often leave micro-burrs that are difficult to reach. This machine utilizes a vacuum table to hold small parts securely, allowing for high-speed deburring that would be impossible—and dangerous—with manual tools.
Technical Superiority Over Competitors
While several brands offer wide-belt sanders, Jonsen machines available through RMT stand out due to several key engineering choices:
- Multi-Station Versatility. Most competitors offer “one-size-fits-all” heads. Jonsen machines are built with a modular station philosophy. You can combine a wide abrasive belt (for heavy slag removal) with a planetary brush station (for edge rounding) and a final finishing belt in a single pass. This “one-and-done” processing reduces material handling by up to 70%.
- Precision Feed Systems. Jonsen uses high-precision vacuum or magnetic conveyor beds. This allows for the processing of very small parts—some as small as a postage stamp—without them being thrown by the abrasive force. Many cheaper brands lack the suction power or magnetic strength to keep small workpieces stable, leading to part damage or machine downtime.
- Reduced Consumable Costs. A major hidden cost in finishing is the price of abrasive belts and brushes. Jonsen machines are designed with oscillating heads that use the entire width of the abrasive material, preventing “grooving” in the center of the belt. This extends consumable life by approximately 25-30% compared to fixed-head competitors.
Consistency and Safety on Your Shop Floor
Perhaps the greatest advantage of Jonsen equipment is the elimination of the “Grinding Room Bottleneck.” Manual grinding is physically taxing, dirty, and prone to human error. A part deburred by hand at 8:00 AM will look different than one finished at 4:30 PM.
- Uniformity. Jonsen machines deliver the exact same radius and finish on every part, 24/7. This consistency is vital for industries like medical device manufacturing and aerospace, where tolerances are non-negotiable.
- Safety. By automating the process, RMT helps shops move workers away from the hazards of flying sparks, metal dust inhalation, and repetitive motion injuries (RSI).
