Rounds a rough log, i.e. after the log passes this unit, it is rounded to various diameters (from 100 to 200 mm) calibrated along its length.
After the rounding the element obtains a center line that remains unchanged throughout the procedure. Thus the upper and lower cutter will be symmetric about the center line.
This unit processes the element from up and down to obtain a desired shape in accordance with the cutting chart.
This unit cuts the element into finished dimensional lumber depending on the cutting chart. When log structures are produced, this unit is disabled.
The installed lathe should be easily accessible and well-lighted. The lathe is installed on a foundation with the depth depending on the ground type but no less than 600 mm and attached to the foundation by six 16 mm anchor bolts. After the installation onto the foundation the lathe is leveled. The level is mounted onto the foundation. Maximum allowable horizontal deviation is 0,2 mm along 1000 mm. The foundation is then cemented and consolidated; then the anchor bolts are tightened.
The manufacturer provides a 1 year warranty for all equipment
All machines are equipped with cutting tools (excluding saws, as 668C can use saws of various manufacturers at the user’s discretion. Saw specifications are listed in the Equipment Certificate). An additional agreement for commissioning and start-up may be concluded.
This machine is designed for processing of round softwood and hardwood trunks of 3rd grade and above as per GOST 9463-72; GOST 9462-71.
The Customer forwards an order for additional equipment or spare parts required, upon its receipt the Seller determines manufacture and delivery time.
Machine manufacture time is within 1-1,5 months.
50% advance payment and 50% when the equipment is ready for shipment. 3% discount may be granted for 100% advance payment.
Using 0,72 utilization rate for calculation:
– Minimum: 830 running meters per shift;
– Average: 1 900 running meters per shift;
– Maximum: 2 765 running meters per shift.
Chips (after rounding, non-pulp – with bark),
Scrap (after smoothing),
Sawdust (after cutting).
Two types of sawdust disposal depending on production facilities are considered (not included into machine price):
– scraping conveyor (preferable);
– pneumatic conveying.
668C lathe is a feedthrough machine, so the maximum length of a log is of no importance, the only limitation is butt end diameter which should not be over 260 mm. Minimum log length is 1800 mm.
Lathe make | Rough knife | Finishing knife |
