Double surface planer provider by v-holdmachinery.com: 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. See additional information on 2 sided planer.
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.
A typical hydraulic down-acting press uses a pair of hydraulic cylinders, one on each end, to generate the tonnage required for the down stroke of the machine. Traditionally, these machines have a C or O frame profile design. With both types, when facing the front of the machine the hydraulic cylinders are located on the left and right hand side of the upper beam. Since the upper beam is being pushed down and up with hydraulic power, the upper beam will fall during a power outage and could create an unsafe environment. Down acting presses are commonly blocked at night to take pressure off of the hydraulic system. The lower beam does not move during bending so the operator will not get feedback that the brake is engaged.
A mortise is a square slot cut in the direction of depth for the purpose of making a mortise and tenon joint in a wooden piece. The mortising woodworking machines are used for cutting mortise and tenon joints which are very laborious and time consuming operations. There are three types of mortisers, namely (1) hollow chisel mortiser (2) chain mortiser and (3) oscillating bit mortiser. The hollow chisel mortiser, the most commonly used woodworking machines, consists of a revolving spindle carrying an auger bit at the bottom end. The auger bit rotates at a high speed inside a hollow chisel of square section. When the chisel is forced into the wood, the bit bores a square hole by the sharp end of the chisel, the auger bit and chisel thus work together and perform boring of a square hole. The depth of the mortise is regulated by means of an adjustable depth stop. The spindle is rotated by an electric motor, and tool-feed is obtained by pressing foot-lever.
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.
A drill press is simply a fixed in place version of a hand drill, it’s great for precise work. With an adjustable table beneath the chuck with a hole in its centre, a spinning drill bit can pass cleanly through a work-piece. Drill presses come as either freestanding floor models or for worktops. The drill press is powered by an electric motor, driving it via a system of pulleys or gears. The drill bit is locked into the chuck, then driven down using a hand powered lever system, and a spring pushes it back up when pressure on the lever is released. A number of adjustments including a moveable table depth, a depth gauge to set the distance the spindle travels and pulley adjustments to change speeds increases the tools functionality.

The woodworking machines are the machine designed to work with wood. These machines, which are typically powered by electric motors, are widely used in woodworking. Grinding machines (used for grinding down to smaller pieces) are sometimes included in the definition of woodworking machinery. Modern carpentry shop, in addition to the hand tools described earlier, requires the use of some power-driven machines, particularly where largescale production is to be obtained. The size and capacity of the machines used depend on the size of the general run of the work to be done. Machines chosen for carpentry shop must be well built, and their accuracy should be dependable. They should be well guarded to protect the worker from the hazards of operation.
