One Pass & Done
Log Rip-sawing Machines
What is LTPS?
LTPS (Log Through Pass Sawmill) is a family of saw-milling machines intended for processing small diameter logs into dimensional lumber (without slabs) in one pass. The machines combine few milling spindles for profiling and sawing spindle for rip-sawing of profiled work-piece. There are few LTPS models available:
LTPS-140: for small logs and dowels up to 7.75";
LTPS-150 (model: E, D, ME, XP) for logs up to 9";
LTPS-300 New Generation LTPS for logs up to 12";
What are Benefits of LTPS?
Logs are centered, profiled & rip-sawn in 1 pass;
LTPS -machines are many times more productive than band saw mills;
Better product yield than in other typed of sawmills;
Lesser foot print and personnel;
LTPS-machines are well balanced in terms of price/throughput, in other words for unit of $ the owner gets much efficient productivity;
LTPS-machines are robust and reliable, proven working in rough conditions since 2008;
LTPS-machines are flexible and can be re-set for different cut-profiles during 1-3 hours (about 100 different profiles where created by 2024);
LTPS-machine can allow a small business to step up onto new level of productivity;
These machines can be installed in a shop or in a field under an awning or in a shed;
What is productivity of LTPS?
One should expect 5-20 thousand BFM of milled products per work-shift.
Please, note: in general the productivity is a function of several componets:
the throughput capacity (the power of motors);
the diameter of logs;
the final cutting profile (how much wood fiber must be reduced);
infrastructure and logistics (in-feed/out-feed automation);
wood species & moisture content;
tooling sharpness;
For example, LTPS-150XP can mill logs with speed 19-50 ft/min (6-16 m/min). But milling 6" dia logs will produce less BFM than milling of 9" dia logs, though the feeding speed can be not much different.
Who may need LTPS?
LTPS -machines are efficient solution for small & medium size businesses:
saw-milling businesses utilizing big amount of small diameter raw stems;
Logging business who looks for effective ways to recover lumber from small diameter stems efficiently at a job site;
businesses utilizing beetle or fire killed stems;
Pallet board manufacturers;
What are cons of LTPS?
The price is higher than basic band saw-mill;
Log sorting is required;
Proper waste management is required;
Re-setup to a new profile may take 2-4 hours, depending on complexity of the target profile;
Motorizes automated Log-infeed & out-feed are required for higher throughput;
3-phase power is required (460V/60Hz or 380V/50Hz);
