3U SISAN

Joinery Workshop
A three-station automatic edge sander that takes narrow to mid-width components through calibration, intermediate, and finish sanding in a single pass. Built for joinery and cabinet shops where surface consistency and throughput matter.

Typically chosen by

  • Joinery and cabinet shops that need to progress components through calibration, intermediate, and finish sanding in a single pass
  • Workshops producing smaller moulded or flat components where consistent thickness and surface quality are critical to downstream assembly or finishing
  • Businesses looking to reduce manual hand-sanding time by bringing more of the process through a controlled machine cycle
Before you commit

See it run on your own material

Bring us a sample profile or board and we'll run it through the machine at our Newark showroom. You'll see the output quality firsthand and we can talk through how it fits your workflow - before any decisions are made.

Key specification considerations

Working Width
110 mm and above
The 110 mm minimum makes this machine well suited to narrower components such as door stiles, drawer fronts, and small cabinet parts — confirm maximum working width with IWM before specifying.
Working Thickness
5 mm to 42 mm
Sanding Stations
3 (1 belt roller + 2 brush roller units)
Three independently adjustable stations allow calibration, intermediate, and finish sanding in one pass, removing the need to run components through multiple machines or set-ups.
Total Installed Power
4.29 kW
Three-phase 380 V / 50 Hz supply required — confirm your workshop supply is suitable before ordering.
SpecificationValueNotes
Working Width (minimum)
110 mm
Maximum working width is not published in available data — talk to IWM to confirm the upper capacity before specifying against your widest components.
Working Thickness Range
5 mm to 42 mm
Number of Sanding Stations
3
Station Configuration
1 belt roller unit, 2 brush roller units
The combination of a belt roller and two brush rollers suits both flat and lightly profiled or textured surfaces — discuss your component profile with IWM if there is any surface relief.
Station Adjustment
Independent on each station
Oscillation
Independent oscillation motors on each station
Independent oscillation on each head reduces the risk of sanding marks and cross-grain scratching that can occur when all stations move in phase.
Conveyor Speed
Inverter controlled
Variable conveyor speed lets operators tune feed rate to material species and abrasive grit without mechanical change-parts.
Total Installed Power
4.29 kW
Electrical Supply
380 V, 50 Hz, three phase
Confirm three-phase supply availability at your distribution board before ordering — contact IWM if you need guidance on amperage requirements.
Machine Dimensions (L × W × H)
2240 × 800 × 1200 mm
Allow additional clearance beyond the machine footprint for infeed and outfeed of long components, and for extraction ducting connections.
Machine Weight
540 kg
At 540 kg, floor loading capacity should be checked, particularly on suspended or older workshop floors.

Is this the right
machine for you?

Choose the 3U SISAN if...

  • You need to calibrate, intermediate-sand, and finish components in a single pass without re-jigging between machines
  • Your work regularly involves narrower components — such as door stiles, drawer fronts, or cabinet parts — that require a consistent and repeatable surface quality
  • You are processing components at volumes where manual sanding is creating a bottleneck or inconsistency, but do not yet need a full wide-format machine
  • Your workshop produces both flat and lightly textured or brush-finished surfaces and needs a machine configuration that handles both

Consider an alternate model if...

  • You are primarily sanding wider panels or board material — the MORBIDO 1300 or LUNA 1000 PRO / LUNA 1300 PRO may be more appropriate depending on your volume and surface requirements
  • Your throughput requirements are lower and a two-station machine would suffice — the MOSTRO 1300 2U or MOSTRO 1300 2U S are worth discussing with IWM as a potentially simpler specification
  • You only need calibration sanding without a finish pass, in which case a single-head machine may represent better value for your workshop
  • Your working widths consistently exceed the capacity of this machine — talk to IWM about the LUNA 1300 PRO as a wider-capacity alternative
