A Woodworking machine is a machine that is intended to process wood. These machines are usually powered by electric motors and are used extensively in woodworking. Sometimes grinding machines (used for grinding down to smaller pieces) are also considered a part of woodworking machinery. [1]
Rotating abrasive wheels on a bench grinder. 8 in (200 mm) wire brush mounted to bench grinder (tool rest in foreground). A bench grinder is a benchtop type of grinding machine used to drive abrasive wheels. A pedestal grinder is a similar or larger version of grinder that is mounted on a pedestal, which may be bolted to the floor or may sit on ...
The drawknife would further refine the leg shape. The finishing stage was turning the leg with the pole lathe (the pole lathe was made on site). Once the leg or stretchers were finished, being of "green" wood, they required seasoning. Chair legs would be stored in piles until the quota (usually a gross of legs and the requisite stretchers) was ...
Surface grinder, which has a head that is lowered to a work piece, which is moved back and forth under the grinding wheel on a table that typically has a controllable permanent magnet (magnetic chuck) for use with magnetic stock (especially ferrous stock) but can have a vacuum chuck or other fixture means. The most common surface grinders have ...
The tolerances that are normally achieved with surface grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. [4] The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, either electromagnetic or vacuum, and a reciprocating table.
At the other end of the size spectrum, machines with 2.4-to-3.0-metre-diameter (8 to 10 ft) plates are not uncommon, and systems with tables 9 m (30 ft) in diameter have been constructed. Referring to the second picture again, the lap is the large circular disk on the top of the machine. On top of the lap are two rings.
The practical drawbacks of a plywood or composite bench top are that they don't hold their corners and edges well, and they can't be resurfaced with a plane—something that is needed from time to time. Maple is the traditional wood. Others used include beech and oak. A potential source for bench top material is old bowling alley lanes. These ...
Structurally, the cabriole leg is weaker as the "S" shape is more accentuated or "bowed"; [9] in any case the cabriole leg must be fashioned out of a solid piece of wood, rather than laminate. [10] Some of the initial rough turning is sometimes carried out using a lathe , but eventually a bandsaw is required due to the complex arc formations of ...
