HIGH SPEED HORIZONTAL RESAWS

High speed machines designed for integration in canter lines or installation behind moulders for horizontal splitting

Stenner’s MHS series of horizontal resaws offers a versatile solution for high-speed precision resawing of timber including hardwood.

Systems are tailored to customers’ requirements for applications such as canter lines or installation behind a moulder to double output by allowing thicker material to be machined and then split. For exterior mouldings such as weatherboard, the sawn finish to the rear (unseen) face of the profile increases preservative retention.

Combining accurate thin kerf blade technology, tilt option for cutting bevel angles and efficient power consumption, the MHS range offers productivity, versatility and economy, maximising the yield from the raw material.

The speed of the track feed is steplessly variable and synchronised with the overhead feed system, which provides excellent control on differing thicknesses of material.

Robust construction gives the stability needed for accurate high-speed cutting, and together with modern control systems, easy maintenance, high operational safety and strong after-sales support ensures solid performance over a long service life.

Stenner’s MHS range has proved popular worldwide, with more than 700 saw units installed in diverse applications.

Key performance data

Available in four models – MHS 9 (pulley diameter 915mm), MHS 10 (1050mm), MHS 12 (1220mm) and MHS 137 (1370mm).

Timber width (as standard) – 305mm.

Variable feed speeds – from 7.5-30m/min to 25-120m/min.

Sawguides

Low friction pressure sawguides of either a disposable or remachinable design provide the excellent blade stability required for accurate cutting. Remachinable sawguides are fitted as standard on the MHS 137.

Sawblade & Pulley cleaning

These machines are fitted with a solenoid-controlled drip feed cleaning system to lubricate the felt pads. In tandem with scrapers fitted to the pulleys, the felt pads ensure the cleanliness of both the pulleys and the sawblade.

Saw straining

Strain is applied to the sawblade by a pneumatic cylinder, which applies force via a linkage when the lever is operated. For safety purposes a low pressure switch is incorporated, which automatically removes power to the main drive motor power (so the machine stops running) if pressure drops to an unsatisfactory level.

Available options include:

  • Remachinable sawguides (std on MHS 137)
  • Stenner spray lubrication system (automatically and effectively lubricates the top and bottom pulleys as well as the sawblade)
  • Tilting heads up to 12°
  • Remote control desk
  • Electric rise and fall of saw unit (MHS 9) or multi-axis positioning system with keypad entry
  • Frequency control of sawblade speed
  • Ammeters to measure load on main motor
  • Sawblade deviation detector
