Cross cut saws are perfect when you need to cut across the grain. There are two choices, a blade above the table coming across the wood, or a blade underneath that comes up through the table. The cross saw with the blade underneath the table keeps the blade at a greater distance from the user so is considered safer. It can also be automated with an automatic feed system which allows you to safely cut multiple pieces in one go, which can be more efficient. Jigsaws are best for cutting tight curves, angles and intricate shapes. Blades for jigsaws are short and straight. They’re clamped at the top and bottom and cut in a reciprocating up and down motion.
Up-acting machines can limit staged bending because of the possibility of ram tilt, staged bending may not be a viable option on an up-acting machine. Because staged bending utilises multiple stations on one machine, if any of the stations on an up-acting machine are too far from the centre, ram tilt may result. Hydraulic presses come in many different forms and are used in many different industries. The basic structure to all presses is a heavy-duty main frame with hydraulic cylinders. The number of cylinders are dependent on the pressure requirement. They are operated by a hydraulic power pack. The presses can be manufactured with heated or cold platens and can have conveyors fitted to make the presses automated.
Sanding is the operation of finishing wooden items after they have been machined. Essentially, a sanding machine performs a sand papering job to produce a uniformly sanded surface. Three common types of sanding machines are : Belt sander; Spindle sander; Disc sander. It has an endless cloth backed abrasive belt which runs over two drums and is used for sanding and shaping flat surfaces. One of the drums is rotated by an electric motor and serves as the driver, while the other supports the belt and keeps it in proper tension. For sanding work by the abrasive belt, the the workpiece is supported by an adjustable table that may be tilted to any desired angle.
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 woodworking lathe is one of the most important machines used in a carpentry shop. This is employed primarily for turning jobs in making cylindrical parts. However, by suitably manipulating the tools, tapers, radii, and other irregular shapes can also be easily turned. It resembles the engine lathe most frequently used in the machine shop, and consists of a cast iron bed, a head stock, tail stock, tool rest, live and dead centers, and a speed control device (Fig. 10.54). The drive, in modern lathes, is individual motor driven ; and a cone pully on the head stock spindle is connected by a belt to a cone pully on the motor shaft.
Modern machinery often requires pneumatic pressure, be it for saws, sanders, impact wrenches, grinders, spray guns, washers, stapling, nailing or pneumatic tooling, the compressor has become a necessity. The compressor consists of: motorised pump; tank for storing the compressed air; on/off control; regulator. There’s also a metal frame on which all the parts are mounted, usually with a carrying handle and occasionally wheels. A drill press can be used to drill round holes, sanding, grooving and mortising with the addition of specialised attachments. See more details at https://www.v-holdmachinery.com/.
