682C rounding profiler

682C rounding profiler is designed for processing of round softwood trunks into rounded logs. It rounds logs and cuts long grooves in the surface. 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.

The price of 682C lathe includes one outfit for log structures of 180-280 mm in diameter.

A log can be cut into precise structures of a good surface quality just in a single run. The log undergoes three processing operations: rounding and smoothing.

682C 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 300 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.

Cutting unit

Cutting unitл

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


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 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.

Additional information on 682C lathe

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

2. Assembly and maintenance
All machines are equipped with cutting tools (excluding saws, as 682C 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.

3. Moisture of raw materials
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. Spare parts
The Customer forwards an order for additional equipment or spare parts required, upon its receipt the Seller determines manufacture and delivery time.

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

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

7. 682C approximate capacity
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.

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

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

10. Dimensions of materials processed
682C 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.

The lathe is equipped with the following tools:

Lathe make Number of knives in a set
Rough knife Finishing knife
682C (rounding) 2 2
682C (smoothing) 4 4
