روش های مکانیکی ارزیابی غیر مخرب

درجه بندی مکانیکی بوسیله ماشین های درجه بندی انجام می شود و به چوب آلات درجه بندی در این روش machine graded lumber نیز می گویند.

در واقع ماشین های موجود مدول الاستیسیته خمشی را با استفاده از تست خمش غلطکی اندازه گیری می کنند.در این روش ابتدا یک خیز (تغییر مکان) از پیش تعیین شده رو به پایین و سپس رو به بالا در چوب آلات ایجاد شده و نیروی متناظر ایجاد کننده خیز مذکور اندازه گیری و ثبت می شود

روش دیگر درجه بندی چوب آلات با ماشین با استفاده از اندازه گیری دانسیته برای تخمین اندازه و تعداد گره ها می باشد که از اشعه X برای تعیین دانسیته استفاده می شود

ماشین های درجه بندی کننده دو نوع هستند

1-      ماشین های با ظرفیت بالا high capacity lumber tester (HCLT)

1-      ماشین های پیوسته continues lumber tester (CLT)

High Capacity Lumber Tester Model 7200 HCLT
