The Band saw blades are thinner than circular saw blades. A thinner saw blade means less wood is wasted when cutting. Whereas, a wider blade makes it easier to cut a deep straight line. Blade size also varies when it comes to the number of teeth per inch, the kinds of teeth and the thickness of the blade. The fewer teeth the faster but coarser the saw cut, more teeth create finer work and can also be used for cutting metal. A further benefit is the height under the guides which allows you to cut deeper than you would be able to with a circular saw. Multi-rips are designed to maximise production speed. So if you want to get the most out of your working day, this could be the one for you.
Up-acting machines typically apply hydraulic pressure from the centre of the lower beam which pushes the lower beam upwards into a fixed upper beam. Tonnage is applied to the centre of the lower beam in an upward fashion. The flex in the bend tends to be even from left to right. Hydraulics are used to push the lower beam up and gravity is used to return the lower beam down. A loss in power will result in the brake being in the open position. Since the lower beam does move during operation, feedback to the operator is given. Knowing the lower beam is moving can be a safety feature. Down-acting machines are preferred if staged bending is important. Staged bending is a valuable option that can significantly improve productivity while minimising setup time.
The jig saw, which is also known as a scroll saw, is used for making intricate and irregular cuts on small jobs. On thin wooden pieces, jig saw can cut in a curvilinear path. These woodworking machines are actually a type of band saw of much smaller size and specially adapted to irregular work. It consists of a base, frame, table, upper and lower chucks, guide assembly, and blade. Chucks hold the blade with its teeth pointing downward. The blade resembles a hand hacksaw blade in regard to its shape. The blade reciprocates vertically up and down and shapes the wood. The table of the jig saw can be tilted for angular work. The special feature of the saw is that it can be used to cut inside curves. A jig saw is specified by its blade-to-arm distance.
The defining characteristic of all machine presses is that they press a work-piece using high pressure to change its shape. While the exact mechanics vary depending on the type of machine press, most machine presses work by pressing a plate or die onto or against a work-piece. The work-piece can either be manually placed into the machine or a through-feed will automatically place the work-piece in the correct position. Once in position, using hydraulics pressure, the machine press pushes the plate or die against the surface of the work-piece, which causes the work-piece’s shape to deform into the shape required by the manufacturer.
The band is available in two models, vertical and horizontal. In the former, two wheels are arranged side by side and the table is mounted underneath. In the latter model, Frame illustrated in Fig. 10.55, the wheels are arranged one above the other in a vertical plane below the table and the band passes through the table. As in the case of the circular table, angular cuts are obtained by tilting the saw table. The size of the band saw is specified as the distance from the saw band to the inner side of the frame. The distance is roughly equal to the diameter of the wheels.
Brushing machines are used as a labour saving tool to clean wood before other work is carried out, such as, gluing wood panels. Cramps and presses are used to assemble the wooden pieces that make up window, door or other types of frames. Dust extraction when working with wood is very important for the health of your lungs. There are several solutions, either large machines that draw the dust away. Or small bags that fit directly to the machine which sucks the sawdust straight into it, helping to cut down the amount of dust in the air.
