GP-S3 Side Sanding Machine

Compact Edge Sanding Machine for Straight and Profiled Board Edges, from 2.5 to 50mm Thick

The GP-S3 Side Sanding Machine is QUICKMO’s compact edge sander, engineered to sand the straight and profiled edges of panels, boards and furniture components — white-body edges, primer edges, chamfered edges and angled edges — in a continuous chain-fed process. Manufactured by Qingdao Kuaimo Technology Co., Ltd. in Qingdao, China, the GP-S3 is built around a modular head configuration, a -45° to +90° adjustable sanding frame, and PLC touchscreen control that automatically adjusts to panel thickness.

The Edge Sanding Problem

Panel and furniture production rarely needs just flat surfaces sanded. The edges — straight edges, chamfered edges, routed profiles, angled edges — also need sanding before finishing. In most shops, edge sanding is done by hand: operators take a sanding block or random-orbit tool to each edge, one panel at a time. It is slow, labor-intensive, and the quality depends entirely on the operator.

The GP-S3 automates this. Panels are fed through the machine on a chain conveyor, and sanding heads process the edges continuously — straight edges, angled edges, profiled edges — at production speed.

Modular Head Configuration

The GP-S3 is built around a modular head system. The operator can arrange and combine different milling and sanding heads along the machine to match the required process:

• Different sanding heads for different grit stages.
• Optional milling heads for edge profiling before sanding.
• Spring-loaded pressure rollers hold the workpiece securely without marking the surface.

This means one machine can be configured for rough edge sanding, fine edge sanding, or a combination — depending on the customer’s product range.

-45° to +90° Adjustable Sanding Frame

One of the GP-S3’s key features is its adjustable sanding frame:

• The sanding head can be tilted from -45° to +90°, allowing it to sand edges at an angle.
• This is what makes the machine suitable for angled edge sanding, chamfered edges and beveled edges — not just straight 90° edges.
• The adjustable head means the same machine handles square edges, beveled edges and angled edges, simply by tilting the sanding frame.

Feed Compensation for Consistent Finish

Each sanding head is fitted with a feed compensation device. This means the head maintains consistent contact pressure along the edge, even if the panel varies slightly in thickness or width. The result is a clean, uniform, scratch-free edge — no over-sanding in spots, no under-sanding in others.

VFD Speed for White-Body and Primer Sanding

The sanding belt speed is variable-frequency controlled, so the operator can match the abrasive speed to the work:

• Slower belt speed for gentle sanding on primer edges, where the goal is to de-nib and smooth without cutting through the paint film.
• Faster belt speed for white-body (raw wood) edge sanding, where more aggressive abrasion is needed.

This makes the GP-S3 useful both before painting (white-body edge preparation) and between coats (primer edge de-nibbing).

Chain Feed, Spring-Loaded Pressure

The GP-S3 uses a chain conveyor with cylindrical guide rails:

• Chain feed provides positive, consistent workpiece movement through the sanding heads.
• Stepless variable speed lets the operator set feed rate for the material.
• 56 mm seamless wide belt pressure rollers hold the workpiece down firmly.
• Spring-loaded pressure means the rollers accommodate thickness variation without crushing or marking the panel surface.

PLC Touchscreen Control, Automatic Thickness Adjustment

The GP-S3 is controlled through a touchscreen HMI running a PLC program:

• Each working group has independent VFD speed control.
• The sanding frame modules advance and retract under program control — no manual adjustment needed.
• Automatic thickness adjustment means the operator enters the panel thickness, and the machine sets the sanding head height accordingly.

This reduces setup time between product runs and makes the machine easy for operators to learn.

Key Specifications

The 120 mm minimum workpiece length means the machine can process small components that larger edge sanders cannot accept.

What the GP-S3 Handles

The GP-S3 is engineered for:

• Straight edges on panels, boards and furniture components.
• Chamfered and beveled edges, using the adjustable sanding frame.
• White-body edge sanding before painting.
• Primer edge sanding between coats.
• Small components as short as 120 mm, which hand sanding struggles to process consistently.

Who Is the GP-S3 For?

The GP-S3 is the right choice when:

• You need to sand straight, angled or profiled edges on panels and furniture parts.
• You want to automate edge sanding that is currently done by hand.
• You process small components as short as 120 mm.
• You need both white-body and primer edge sanding in one machine.
• You want PLC touchscreen control with automatic thickness adjustment.

Shops needing wide-panel flat-surface sanding should look at our 1300R-RP; shops needing contour and profile sanding on shaped parts should look at the GP1300 flexible series. For edge sanding on small to medium panels, the GP-S3 is the compact purpose-built tool.
