F. A. Q.
Here you can find answers to frequently asked questions.
1. How much space is required to operate a circular sawmill?
For operating the angle sawmills, the space is determined by the design of the device, i.e. the width and customer of the cut length required, plus twice the length of the saw head for its start and finish. These dimensions must also include the dimensions of the handling area for the logging and timber removal and storage. See the foundation plans for the most frequently delivered sawmills.
2. What is the basis under the circular sawmill?
Under the saw, the reinforced surface must be formed by either a continuous concrete layer, sufficiently mature and solid enough to withstand the machine load with the loaded wood, or foundation concrete strips need to be created from the vendor's documentation. The maximum height unevenness of the base area over the entire length is 25 mm from the zero line. In the case of a reinforced concrete base, it is necessary to place steel net, respectively armouring min. 10 cm below and below.
3. What is the yield of raw material processing?
In the processing of logs produced by us on angle sawmills, it is possible to operatively change the size of the carved blanks and to maximize the value of wood raw material, whereby a relatively high yield of wood material is achieved even with respect to a larger cutting gap (e.g. against band saw blades) and is around 70% . Circular sawmills produce more sawdust than other sawmills but much less unusable side saw cuttings.
4. What type of wood can be cut at angle sawmills?
It is possible to cut all kinds of deciduous and coniferous woods of different hardness on the angle sawmills. It means that it is also possible to cut very soft woods such as e.g. poplar, as well as hardwoods such as beech, oak, acacia, mahogany, eucalyptus.
5. What kind of products can be produced on circular sawmills?
It is possible to produce all kinds of sawn timber from circular sawmills, starting with construction timber and ending with precise furniture cuts (radial timber, furniture fries).
6. How are individual machines loaded and unloaded during transports?
Individual machines are loaded and unloaded in disassembled condition, i.e. a sliding frame, which is usually divided into two to three parts, is loaded separately and the saw head is loaded separately. The parts of the frame are loaded by the forklift truck with the required lifting capacity in places where no functional parts of the frame are damaged. Loading and unloading is also possible by crane, using ropes, which are fixed in the designated areas, whereby a soft liner (pad) must be provided at the anchorage in order to avoid abrasion of the paint. A pad is not needed if the lifting belts are used instead of steel lifting ropes. The saw heads are lifted by crane by means of lifting lugs located on the saw head beam, or by forklifts by means of lifting devices designed for this purpose.
7. Are circular sawmills normally in stock?
Circular sawmills are not normally in stock, they are produced on the basis of a binding order and payment of an advance invoices; see the General terms and conditions. The saw head parts are pre-fabricated, so that the customer basically only refines the foundation frame assembly (clamps, lifting cylinders, tumblers, straight feeders, loaders, wood feeders, etc.).
8. What is the warranty?
Warranty conditions are governed by applicable law. The guarantee is linked to the number of hours worked in the year. Accordingly, the warranty lasts 12 months (or 24 to 30 months) from the installation of the equipment, but no more than 13 (25, 31) months after delivery of the equipment unless the installation has been made within 1 month of delivery. Parts that are consumables in the technological process are specified at the plant in Lille and are therefore not covered by the warranty.
9. Is the agreed production date binding?
The date of production is always determined according to the actual job load. There may be a case where the customer postpones the advance payment after the delivery date and the number of orders is changed in the meantime. In this case, if you do not pay the deposit by the specified deadline, please check the delivery date by phone.
10. Is it necessary to have extraction already when installing a sawmill?
Extraction is not required when the saw is started up; it is tested shortly after installation and time for routine operator training. However, permanent operation of the sawmill without suction is not permitted.
