Hello, friends. We are Giantway, a sanding machine manufacturer and sanding solution supplier. Today, I would like to give you an overview of our planer sander.
The planer sander is specially designed for cutting and sanding operations. It is ideal for heavy calibration of glued panels, solid wood panels, or bamboo panels where more than 2 mm of material needs to be removed, while still achieving finishing sanding up to grit 180 in a single pass.
This planer sander is configured with three working units. The first working unit is a helical planer head, equipped with 248 sets and a total of 477 knives. This planer head is mainly used for cutting and can remove 1–2 mm of material in one pass.
Before the planer head, the press system includes one line of anti kick-back fingers, double press rollers, and segmented press shoes. The segmented press shoes provide even pressure across the entire panel width. After the planer head, a solid press shoe and an additional press roller are installed to firmly control the workpiece. Thanks to this design, there is no sniping or dipping on the leading or trailing edges of the panels.
The second working unit is a steel calibrating roller with a diameter of 240 mm, complete with an oscillating system, safety system, and dust collection system. The steel roller is mainly used for rough sanding, and grit 80 abrasive belts are commonly assembled on this unit.
The steel roller is equipped with an eccentric shaft, allowing the operator to adjust the roller position easily through a worm gearbox, ensuring simple and stable operation.
The third working unit is a combination head, outfitted with a rubber roller and a sanding pad. The rubber roller has a diameter of 210 mm and a hardness of Shore 55. The sanding pad beam features a dovetail design, making it easy to pull out or push in. The operator can adjust the sanding pad position up or down by turning the hand wheel.
The tension roller has a diameter of 176 mm, and the tension cylinder size is 90 × 50 mm. This heavy-duty design ensures stable belt tension and smooth belt oscillation. Belt oscillation is controlled by Banner sensors made in the USA, which work reliably even in dusty environments.
At the outfeed side of the machine, the feeding motor is combined with a helical gear reducer. The motor is a variable-frequency motor, and its output torque is not affected by feeding speed, ensuring continuous and stable power output for high sanding precision.
The machine is equipped with a brushing unit to clean the panels after sanding. An additional press roller is installed under the brushing cover to ensure smooth outfeeding.
The feed table is welded from steel plates and steel tubes with a thickness of 16 mm. The surface is finely machined on a CNC machining center to achieve a mirror-like finish. Combined with the rubber conveyor belt, this structure allows workpieces to pass through the machine with high precision and stability.
At the front of the machine is the control panel. The start and stop buttons are equipped with indicator lights to show the operating status of the machine for safety awareness. The thickness controller is made by the Taiwan brand TECK, offering accurate measurement, stable quality, and long service life.
An emergency stop button is also installed to stop the machine immediately in case of emergency.
