Knowledge of woodworking machinery and Woodworking cutter for wooden furniture
Guide: If a worker wants to do his job well, he must first sharpen his tools. Next, I will focus on the knowledge of relevant household equipment. As the saying goes, “If a worker wants to do his job well, he must first sharpen his tools.” Furniture production cannot be separated from woodworking machinery and woodworking tools. This article will make an inventory of some common woodworking equipment and introduce their functions, methods and precautions.
01 Woodworking planer
There are many types of planers. According to the different process uses and structures, planers are: flat planer, press planer, four side planer, polishing machine, etc. The flat plane is used to precisely plane the datum plane of the workpiece blank, and can also process the surface adjacent to the datum plane as an auxiliary datum plane. It can be divided into manual feed, mechanical feed, single axis and double axis. The press planer is used to make the opposite surface of the planed datum plane smooth and parallel to the datum plane. The thickness and width of the workpiece can be fixed by the press planer, all of which are mechanically fed. Four side planer is used to process four faces of the workpiece at the same time in one feed. Because of the mechanical feed and multi cutter shaft processing, it has high efficiency. The polishing machine is processed by pure planing, which is used for the final polishing of the part surface. The processing principle is similar to manual planing.
02 Woodworking edge banding machine
One of the woodworking machines belongs to solid wood machinery. As the name implies, the edge banding machine is used for edge banding. Straight edge banding machine is generally used, of course, there are special edge banding equipment. The fully automatic woodworking edge banding machine can complete many processes such as pre milling, gluing, cutting, front and rear end trimming, up and down trimming (rough trimming), up and down fine trimming, up and down scraping, polishing, etc. The edge banding machine is applicable to straight edge banding and trimming of medium density fiberboard, blockboard, solid wood board, particleboard, high polymer door panel, plywood, etc. It can be used once with double-sided adhesive edge banding, cutting edge banding, adhesive pressing, head trimming, chamfering, rough trimming, fine trimming, scraping and polishing, etc. The edge banding is fine, smooth, with good feel, and the sealing line is straight and smooth.
03 Woodworking cold press
Cold press is used to press furniture panels, wooden doors, all kinds of boards and furniture for leveling and shaping, which can make the bonding between boards more firm, with strong pressure and no rebound. The working forms of woodworking cold press can be roughly divided into screw type and hydraulic type. Generally, the performance of hydraulic cold press is good in all aspects. Because the hydraulic cold press has low working noise and fast lifting speed. However, if the hydraulic system is rough, oil leakage will occur. A good quality hydraulic system can better solve the problem of oil seal.

Woodworking milling machine The milling machine is a universal equipment, which can complete the processing of various processes, but it is mainly used for the processing of the curve, straight line and formed surface of the part contour. In addition, the milling machine can also be used for tenoning, profiling and other operations, and sometimes it is also used for plane processing such as sawing. It is one of the indispensable equipment in furniture and wood products processing. According to the number of spindles, the milling machines include single axis milling, double axis milling and multi axis milling. The single axis vertical milling machine is the most commonly used type of milling machine at present, which can be divided into upper axis type and lower axis type, and most of them adopt manual feeding. Simply put, single end milling is only used to mill linear shapes, while double end milling is used to mill arc shapes. If your material is concave, you can use the right knife to mill the right half and the left half, so as to prevent the wood from flying. If your material is convex, it is half of the left side of the right side and half of the right side of the left side. When it comes to milling machines, milling cutters must be mentioned. Milling cutter is a kind of cutter with the most kinds and the most extensive application in wood cutting. It is widely used in furniture manufacturing, wood floor production and other wood products production. Because milling cutters are used in many wood parts processing, there are many types of milling cutters. According to the different clamping methods of the milling cutter on the machine tool spindle, the milling cutter can be divided into a suit milling cutter and a shank milling cutter; One end of the shank milling cutter is provided with a blade, and the other end is a tail shank, which has cylindrical, conical and threaded shapes. Here we introduce the shank milling cutter. The shank milling cutter is mostly installed on the upper shaft end mill and portable router. The shank diameter is 6, 12, 16, 1/4 ″, 1/2 ″ and other specifications, the cutter head diameter is 3~26, and the blade is generally integral (or integral welded). Assembling milling cutter refers to the milling cutter formed by clamping the cutting blade or cutter teeth on the cutter body with mechanical clamping method.
05 Woodworking carving machine
It is mainly used for wood processing, crystal, copper, aluminum, etc. Make it more beautiful. There are many kinds of woodworking carving machines and many brands, leading to uneven prices. The style is customized according to customer needs. It can be used in wood industry, advertising signs, furniture manufacturing, toy and gift manufacturing, decoration industry, PCB manufacturing, etc.
06 CNC woodworking machine tool
CNC machine tools refer to wood processing machine tools controlled by digital signals, which are referred to as CNC machine tools. If the CNC machine tool has comprehensive processing functions (milling, drilling, planing, etc.), it is called a machining center. CNC machine tool is a perfect combination of modern computer technology and traditional machining. It can realize real-time, parallel, networked, digital design and manufacturing, as well as three-dimensional production of products. It can be said that it is the development direction of modern furniture and wood processing machinery. According to their different processing technologies, there are CNC milling machines, CNC drilling machines, multi-function CNC machine tools (machining centers); According to the number of spindles, there are single axis, two axis, four axis, six axis, etc; According to their different shapes and structures, they are portal type, gantry type, cantilever type, C-type, etc.
07 Curve saw
The curve saw belongs to reciprocating motion. There are two types of portable curve saws: vertical and horizontal. They are mainly used for sawing the circular arc of the workpiece curve. The base plate of the vertical curve saw can be adjusted 90 °~45 ° arbitrarily with the saw blade. When sawing straight edges, the base plate is perpendicular to the saw blade, and when sawing beveled edges, the base plate is adjusted to the required angle. During operation, hold the handle with both hands and slowly push the cutting along the line. The horizontal curve saw has no base plate, and the blade is parallel to the motor shaft. During operation, the right hand holds the handle and the left hand holds the body to cut along the line.
08 Woodworking sander
Grinding is one of the processes widely used in the production of furniture and wood products. It is the use of abrasives to finely process the machined surface of parts or components. Grinding is commonly used in: workpiece size and thickness grinding; Workpiece surface finishing grinding; Brushing processing of final decoration surface, etc. In most cases, grinding is the last step in the machining process of furniture and wood products.
The types of sanding grinding are as follows: at present, the most commonly used sanding equipment is the wide belt sander, which can be divided into single belt, double belt and multi belt sanders according to the number of sanders; According to the processing position, it can be divided into upper grinding, lower grinding and double-sided grinding sander; According to the grinding direction, it can be divided into longitudinal grinding type and vertical and horizontal grinding type; It can be divided into two types according to sanding mode: contact type and pressing plate type. According to the feeding mode, it can be divided into two types: caterpillar feeding and roller feeding. Crawler feeding: mainly used for sanding plywood, blockboard and window frame. Roller feeding: mainly used for sanding of medium density fiberboard and particle board.
