Technique To Make Professional Woodworking Safe

Flush Fix  

It is difficult and risky to flush mill the edges of panel components on a spindle moulder. But fear not! The solution to the problem is FLUSHFIX, a work piece support for the flush milling of edges. Brought to you by Aigner, Germany, Flushfix can be easily mounted, upright or flat, without tools to the mounting rails, integral fence or the mounting plates. It can then be adjusted to the work piece breadth. It ensures exact flush milling of the edges of all kind and provides full use of the cutting breadth of the tool.

As the work piece slides on the rail smoothly, the milling is done precisely. Moreover, the trimming tool can be adjusted to the exact level of the rail. For flush milling the edges of a broad flat work piece with Flushfix and Centrex, the pieces are pressed firmly to the rail by the Centrex pressure shoe. Flush milling the edges of a broad upright work piece keeps the work piece pressed firmly against the rail by pressure modules and occupies less floor area. In all the cases the surface is hardened by anodic treatment.

Rim Edger

In the panel processing factory milling or levelling the protruding laminate veneers of the work piece is done. Normally, a little over size laminate/veneer material is processed over the work piece with surface material protruding a few rim from all the sides. To solve the problem Aigner has designed a rim edger which can be mounted on any spindle moulder. It can be quickly mounted at the desired height to the integral fence and its continuous fine adjustments are brought about by the integral fence. It is checked that both the edges are in line. Then the tool and the fence are set perfectly so that the trimming is edge to edge. In case of flush edging of protruding rims of a thin work piece with the Rim Edger and Centrex, the work piece is processed firmly by the vertical pressure shoe. This assures a faster and smoother trimming of the surface material. The Rim Edger can also be used for thicker work pieces by using tools which are a few mm more than the thickness of the work piece. In case of the Rim Edger too, the surface is hardened by anodic treatment.

Both the machines are manufactured with German precision& engineering thereby assuring long life and repetitive accuracy.

Band Sawing

In India one can find band saws with manual trolleys and 2 to 3 mm Kerf. The feed speed of such saws is uneven as it is manual/pushed feed and the resultant surface of the saw planks is quite rough and needs about 2 mm to uniformly plain the entire surface. This leads to the loss of quite a good amount of timber at every stage. However, it is possible to save 50% wastage if proper care is taken regarding:

• Selection of equipment

• Thin Kerf blades

• Uniform feed speed

• Accurate positioning for thickness and elimination of over sizing of timber

• Proper sharpening of the blades and its maintenance

The equipment should be properly engineered and the machine should work vibrations free and should consume optimum electric power. Also the machine should have accurate carriage so as to assure least tolerance and the carriage should be hardened & stress relieved to guarantee long life performance. Besides, reducing the Kerf of the saw blade there can be drastic recovery of lumber. Such technology assures 70 to 80% recovery in lumber. Therefore, by ensuring the accuracy of the Kerf and the feed speed smoother surface of the saw timbers can be achieved and thereby resulting in lesser material removal for planning. Also proper care should be taken while sharpening the blades and setting the Kerf process.

Hence, with proper care and precaution one can achieve the optimum efficiency of band sawing and improve timber yield and reduce the wastage of precious timber and natural resource.
 

Planers & Moulders

Planers and moulders can enhance product quality of plantation timber. A planer is used for surface planing (i.e. the surface of the sawn timber is normally planed in a simple planer with a single cutter head) or thickness planing, where the thickness of the work piece is reduced to standard dimension. Four side planing is an extension of single side surface planing where the planing machine is equipped with four cutter heads to permit surface planing of all four sides of the work piece during a single pass through the machine.

On the other hand, moulding of timber is defined as the process of producing a profile (it can be of various designs and uniform along the complete length of the timber) along the length. The simplest form of moulding machine is the single vertical moulder or the spindle shaper. Straight moulding, rebating, grooving, bevelling and chamfering, edge moulding, tenoning, shaping etc. can be carried out using a single spindle moulder. The multiple spindle moulder comes with four, five, six or more cutter heads facilitating simultaneous moulding and planing of the timber section or work piece at a single pass through the machine. Mouldings, beadings, picture frames, staircase railings, flooring, panelling, door and window frame sections etc. can be made on the multi spindle moulders and timber can also be machined through the multi spindle moulder.
