SSF 420

Mössner band saw SSF 420

The most compact Mössner band saw.

Ideal machine in operability and when only little space is available. Even the “smallest” Mössner is a very low-vibration and powerful machine due to its heavy grey cast iron construction. Saw blade dimensions from 6 to 13 mm are possible.

Different voltages can be realised depending on the recipient country.

jaw guides with inserts
Bracket jaw guides bottom and top including carbide-tipped guide inserts for bracket jaw guides

Inserts for jaw guides
Carbide-tipped guide inserts for jaw guides

Roller guides
Roller guides inducing guide rollers used for curing speeds starting at 250 m/min.

Guide rollers
1 set = 2 pieces with rim, 2 pieces without rim

Guide dimensions depending on the saw band used

Emergency push-button

Additional foot switch on the lower part of the machine for emergency stop.

Magnetic brake upper wheel

Automatic braking of the upper wheel by magnetic brake, in case of loss of tension or saw blade breakage.

When applying the magnetic brake upper wheel for a SSF 420, a Manual saw band tensioning device with hydraulic indicator is also required.

Straight cutting device
(not available with feed table)

The straight cutting device is placed on the worktable with 4 pins. The feed is manual. By means of a mitre-adjustable feed angle and an adjustable cross-cut fence, cuts can be made at an angle of up to 45° and in lengths of up to 230 mm. The cutting depth can also be limited with another adjustable stop.

Technical data:

  • Size: 400 x 400 mm
  • Feed way: 240 mm

Parallel ledger

Parallel ledder consisting of:

  • Scaled guide bar
  • Guide cone with clamping
  • Stopper lineal
  • Maximum adjustment range of ledger:

Type SSF 420
up to 290mm

Type SSF 520/SSF 630/SSF 1600
up to 390mm

Type SSF 801
up to 550mm

Workpiece holder

Workpiece holder for safe and exact guiding of the workpiece.

Cutting support device
The cutting support device is used to cut thin sheets with thickness up to approx. 6 mm. The small contact surface prevents the sheet from vibrating and thus reduces the risk of saw blade teeth breaking.

Alignment with laser

For exact positioning a laser beam projects a laser beam on the surface of the workpiece. This beam points out the cutting channel.

Used laser: Helium-neon-laser with a prefixed lineoptic, not dangerous for the eye (corneal reflex).

LED lamp

LED lamp for lighting of the working area.

Feed tables

  • Feed table with 4 T-grooves
  • Feed way depending on machine type
  • Work table inclinable, to the right side approx. 8° and to the left side approx. 14°
  • Instead of usual table execution

Available versions:

  • Manual feed table with locking mechanism (not available for type SSF 801)
  • Manual feed table with lead screw
  • Electric feed table with servo motor and ball screw

If an electric feed table is selected, the SSF 420 band saw machine is supplied incl. manual band tensioning device with hydraulic display. From size SSF 520 onwards, this device is serially included in the band saw.

Feed way / Table sizes:

  • SSF 420
    Feed way approx. 230 mm, table size approx. 600 x 700 mm
  • SSF 520, SSF 630, SSF 1600
