685C rounding chipper edger

685C rounding chipper edger is designed for production of rounded logs with a long groove for blockhousing from 180-280 mm diameters, shaped beams and edge-surfaced lumber from 180-240 mm diameters. The machine can be used at bottom timber landings of harvesting companies, forest farming facilities, etc. It can function in a closed unheated space at ambient temperature of -16°to +30°С.

You can see the lathe in action by downloading a video presentation or watching it online (see below).

685C lathe main units

Оцилиндровочный узел

Rounding unit

Rounds a rough log, i.e. after the log passes this unit, it is rounded to various diameters (from 180 to 280 mm) calibrated along its length.

Rounding and cutting units

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.

Фрезерный узел

Cutting unit

This unit processes the element from up and down to obtain a desired shape in accordance with the cutting chart.

Пильный узел

Sawing unit

This unit cuts the element into finished dimensional lumber depending on the cutting chart. When log structures are produced, this unit is disabled.

Additional information on 685C lathe

1. Warranty
The manufacturer provides a 1 year warranty for all equipment

2. Tools, commissioning and start-up
All machines are equipped with cutting tools. An additional agreement for commissioning and start-up may be concluded.

3. Materials processed
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.

4. Machine manufacture time
Machine manufacture time is within 1-1,5 months.

5. Payment terms
50% advance payment and 50% when the equipment is ready for shipment. 3% discount may be granted for 100% advance payment.

6. Waste
Chips (after rounding, non-pulp - with bark),
Scrap (after smoothing),

7. Sawdust disposal
Two types of sawdust disposal depending on production facilities are considered (not included into machine price):
- scraping conveyor (preferable);
- pneumatic conveying.

8. Dimensions of materials processed
685C 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 380 mm. Minimum log length is 3000 mm.

9. Saw specifications
Saws for linear sawing with carbide plates as per GOST 6769-79 are to be used on this device. Register diameter 50mm. Outer diameter for side cutting of logs of 210-280 mm in diameter no less than 560 mm and no less than 500 mm for logs of 180..200 mm in diameter. Number of teeth for a 560 mm saw is 28, blade thickness 3,6 mm, plate width 5,2 mm. Rake angle 25-30. Machine operation depends on proper saw maintenance and usage. Saws must be forged and well-sharpened. Maximum tooth blunting radius 50 μm. Saw blunting is manifested by white bloom on its surface. No more than 2 saws are allowed for log rounding. Up to 5 saws are allowed for cutting of 150 mm high beam. Key groove 14x4 mm. Compensatory notches - 6. 28-30 teeth.

Assembly and installation

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 20 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.
