Shopping for sanders

With so many options, the trick is matching the machine to the task

It’s just about unanimous – woodworkers would prefer not to sand. That’s because it’s a dirty, temperamental task that can ruin parts and entire projects in a heartbeat. It creates more waste than any other aspect of working wood and keeping ahead of the dust is both expensive and noisy. The airborne fines are toxic because of their microscopic size, and they’re often contaminated with man-made additives such as adhesives, resins, plastic and fillers.

But the trade-off is dramatic. There are few things as satisfying as applying a stain or clearcoat to a well-sanded project, and then watching the grain and color jump off the surface.

Woodworkers don’t just sand flat boards, so a variety of machines reflects the diversity of needs. There are wide belt sanders for panels, brush sanders for textures and moldings, profile sanders, edge sanders and buffers. Then there’s equipment for CNCs, aggregates and robots. If the surface isn’t right, the whole project looks wrong. So, it’s important to match the machine to the task.

South Bend also presents a 37” wide belt sander, model SB1096, with a 15-hp, 3-phase main motor and digital controls for the table elevation and conveyor speed. The operator can dial in exact settings from a minimum of 1/8″ thick work to large tables and slabs. The belt moves side to side automatically (it’s variable from 5/16” to 5/8”) to get the best sanding results, and also to prolong the belt life. There’s an Amp/load meter to monitor the machine’s performance, a built-in regulator/water separator, and an emergency stop panel and disc brake for safety. There are keypad controls for the table elevation, with a digital readout.

GDP GUHDO ( has developed a new CNC Sanding Unit named the CNC-Ag, which is designed for use on CNC routers and machining centers such as Weeke, Homag, SCM, Biesse, HolzHer and others. Made in Germany, this unit is ideal for sanding flat panels such as cabinet doors and furniture tops. It simply mounts to a standard tool holder (16mm shank), or, if the machine has an HSK interface then the shop can order it on a 16mm HSK heat shrink holder, which is the preferred clamping system for optimum performance. GDP will mount the sanding unit to the tool holder at no charge. The unit has a floating distance of 3.2 mm and a Velcro backed 150 mm (5.9”) diameter sanding plate. It’s equipped with three different springs for presetting pressure (resistance). GDP says that until now, the only viable option for sanding parts on a CNC machine was an investment in a floating head aggregate. With the new CNC Sanding Unit, it is within reach of many smaller shops. The company is based in Mariette, Ga.

Smaller professional woodshops have an opportunity to enter the world of robotics with a new sander from OnRobot ( The all-electric random orbital sander is an out-of-the-box tool that’s easy to use with all major collaborative and lightweight industrial robots. Included is a plug-and-play sanding tool, a variety of standard sanding and polishing pads, easy-to-use programming software, an optional force/torque sensor and a Grit Changer that changes grits without any operator intervention. The sander supports flat, curved and uneven part geometries, and adding a force/torque sensor lets it adapt to surface variations or part misalignment.

Triton’s new oscillating spindle/belt sander, the Tspst450, was introduced a few months ago and has just been added to the catalog (Woodworker’s Supply). The benchtop machine has dual action rotating and oscillating movement, and the tabletop tilts as far as 45 degrees for chamfering and edge work. It takes sanding sleeves from 1/2″ to 2″ diameter that are 4-1/2″ tall and the belt is 4” × 24”.

Stanza Machinery in Charlotte, N.C has added the Galaxy Double Rotation sander to its catalog. Each of the sanding heads rotates on the Z axis as it spins on the X axis, so all of the parts are sanded equally from all angels and directions. Each of four sanding units rotates around its own axis while the main carousel is also turning. The Galaxy comes standard with a 7.5 kw vacuum table motor, which holds parts securely while they go through the machine. The rotation, carousel and conveyor speeds are all variable, and the machine is equipped with an easy-to-use PLC and vacuum suction belt.
