UPT-250M is a cutting-type milling-sawing machine designed for longitudinal sawing of low-grade wood with a diameter from 80 mm to 280 mm into high-quality edged sawn timber. The cross-sections of the finished product can vary from 60 mm to 160 mm  in width (given by the distance between the side cutters) and from 10 mm to 160 mm (200 mm  optional) in height (defined by the number and distance between horizontal discs), while the length of the workpiece can be from one to six meters. On the UPT-250M machine, two mills are involved in sawing the logs, which remove the side surfaces of the log, and two blocks of horizontal discs that follow, which make sawing the planks prepared after the cutters. At the exit of the machine turns out ready horizontal stack of boards and two slabs. 


The presence of side mills in the sawing scheme ensures the operation of horizontal discs on a clean surface, thereby greatly prolonging the life of the saw blades. The mechanism of displacement-extension of the side mills is equipped with an electric drive, due to which the operator can quickly change the width of the chopping block during operation of the machine, and the value will be displayed on the electronic board of the control panel. The visual contours of the future block are projected directly onto the log with powerful linear lasers that help to correctly position the workpiece on the receiving table.

Thanks to a number of original technical solutions used in UFT-250M, we managed to surpass similar types of pass-through type in technical characteristics, namely:

• Reduce energy consumption to 75 kW without loss of performance
• Reduce the thickness of the cut to 3 mm, due to which increased the percentage yield of suitable lumber
• Possibility of processing logs with a high degree of taper and curvature
• Get rid of the accompanying thin slab and the so-called "noodles" and "splinter"
• Due to the operational change of the distance between the side mills, there is no need to pre-sort the wood

Main advantages and differences:

Processing of low-grade wood with a diameter of 80 mm to 280 mm and a length of 1 m to 6 m in one pass

Maximum removal of side mills up to 80 mm.

The mechanism for moving and extending the side cutters, which is responsible for the operative change of the width of the boards or beams, is equipped with an electronic ruler with 4 programmable buttons for any size from 60 mm to 160 mm. Change the current size by pressing just one button.

The UPT-250M machine is equipped with powerful linear lasers that project the contours of the future plank onto the workpiece.

.  Standard features include: It’s a system of automatic sequential start-up of all engines and drives It’s a smooth adjustment of feed rate It’s an automatic feed rate limiting system when main engine is overloaded It’s to load indicator of main engines Adjustment of the maximum power consumption of the machine It’s heating of the electronic part

UT-250M swing housings provide optimal protection of working personnel from sawdust and to open access to the internal structure of the machine

The built-in housings and suction system ensures timely removal of chips and sawdust from the working area.

The receiving table is equipped with manual tilters of the log, with which the workpiece can be lifted above the table and rotated.
