Stationary circular saw: for cutting Assistant

Stationary circular saw is used for sawing workpieces made of wood, metal or plastic. Such a device is irreplaceable in the garden, in a home studio, in the carpentry shop. The tool is represented in a wide variety of species: devices having a similar design, different functionalities. The correct choice of saw blade will depend on the effectiveness and durability of its work.

Stationary Circular Saw: Tool device

Stationary circular plate belongs to a class of carpentry equipment. It consists of a body equipped with one or two handles. It is on the basis of a frame having a rigid structure. The working surface is made of cast iron or steel. In some models it is aluminum.

The working surface can be cast or fabricated. The first embodiment is characteristic of a powerful machine-conveyers. Such a tool is more stable and has a large weight, whereby the need of reliable arrangement of the concrete base for its placement. In small machines table circular saw can be prefabricated, which provides mobility settings.

Important! For the convenience of cutting out the material on the working surface of the guide lines are plotted.

On the surface of the groove is provided, which serves for the free rotation of the saw blade. In some models, it can be tilted, which is possible thanks to the calibration of the leading soleplate. This allows cuts in a wide range (fixed) angle. In the inoperative position the disc is closed by a special casing.

Behind the saw blade located riving knife whereby sawn wood workpiece is not reunited again that may occur under the action of elasticity of wood fibers.

Under the worktop is a motor shaft of which a pulley by the torque transmitted to raspilochny saw blade. It also uses a belt drive. However, there are models in which the torque is transmitted to the propeller means. The pulley serves as a support for the saw blade, which quickly begins to rotate around its axis, carrying the cut material.

Important!Stationary saws carries the cut material only in a straight line, without the possibility of shape cutting.

The working surface can be equipped with expandable element, through which you can increase the area of ​​the machine. stationary saws is operated by buttons that are recessed into the control panel. This prevents accidental activation of the unit. Some models are equipped with a safety switch.

Strengths and weaknesses of electric circular saw,

Electric circular saw has distinct advantages over other tool embodiments. The device operates at high speeds, thereby large disk rotational speed and performance of cutting quality.

The unit is designed so that its operation is safe. Raspilochny disc circular saw for wood with a special protective cover is closed, thereby avoiding the likelihood of injury from the sharp teeth of the blade unit in the rest position.

Due to the stationary frame, made of durable material, provided the stability of the equipment. In addition, reduced tool vibration during operation, which contributes significantly to the quality and accuracy of the material processing. Despite the overall size and large-scale installations, circular saw operates with a low noise level, which contributes to comfortable operation of the device. In addition, it creates the ability to perform fine-tuning tool.

In the circular saw with a table length of the workpiece can be processed more than 1 m. Such a tool is also characterized by a wide range of process materials. The saw can handle the wood, particleboard, fiberboard, plywood, plastic and even with products made from soft alloys. use the appropriate drive is required for the latter type of material.

Important! Most stationary models are equipped with a dust collector.

The main disadvantage of stationary circular saw is the high cost of the tool, which is due to the quality of the assembly and the creation of conditions for the safe it use.

Varieties of circular saws according to the structure

Circular saws for tree different design performance, which is reflected in an instrument of mobility and sizes of workpieces.

To carry out a large amount of repetitive work using circular stationary structure. The tool is located on a separate frame which has impressive dimensions. Such an arrangement requires a separate space for installation arrangement with a reliable foundation. Stationary saws have a high capacity motor, which allows to process large workpiece.

Depending on the degree of mobility of stationary circular saws can be heavy or light weight. In the first case, the tool is equipped with a molded base, whereby the structure has a high weight. Such saws allow for propyl depth of 14 cm. Lightweight devices are equipped with supports to open or removable supports, which can be accomplished through transport or movement of the device.

Some models can be placed on the table. For this, they have a low stand, which contributes to stability of the structure. Such a saw can perform propyl and 5 cm depth.

There is a third type of device, which is represented by a hybrid disc circular saw. It has a frame molded of smaller size (compared to heavy saws). Such a tool operates with less noise and enables the product to treat in width to 75 cm. This is the most justified choice for the mini-workshop.

Characteristic features of manual and table saws

The second tool is a kind of circular table saw mini. It has smaller dimensions than the previous version. This type of device mobility differs, the ability to process the workpiece width up to 60 cm. The depth of such cutting tool is 4-7 cm. The disadvantage of this tool is an increased level of vibration during operation, which adversely affects the quality of cutting.

Circular mini machine is a hand tool, which is characterized by mobility and the ability to handle the workpiece in different planes. This saw is characterized by low power and requires periodic rest. Hand tool has a limited range of services.

In addition, the device characterized by low level of security, which is manifested in proximity to the working surface of the hands, incomplete protection of the saw blade, the need to observe not only for the cutting process, but also the position of the motor to reduce the likelihood of misalignment of the cut and return tool.

More expensive equipment of this type is a manual circular saw, with a fixed installation. The housing unit is massive, but safe. The tool has a special platform, through which the saw is mounted on the machine.

Tool types depending on the depth of cut and workpiece material

Depending on the intensity of use of circular saws are classified into subtypes. The tool can be domestic and professional. First Embodiment devices performs an extended range of papers, but it can function continuously not more than 15 minutes, after which it is necessary to provide a break in the tool at such same period.

Household devices are divided into small, medium and large machines. The circular saw performs the first type cut depth 4-4.6 cm, the second - 5-5.5 cm, the third - 6.5-7 cm.

Professional saws can operate continuously throughout the working day. They are able to process the material of different hardness and of any size. The depth of the cut performed by such a tool is 6,5-14 cm.

Depending on the performance of the treated surface of the work and material distinguish stationary circular saw blades for wood, metal tools and submersible device type. Saws carried wood sawing wooden elements at different angles.

Circular saw for metal is a versatile tool that has high capacity and is adapted to work with different cutting discs. These may be variants of standard abrasive articles and increased strength. Such a universal tool can handle the pipes, profiles, sheets of metal blanks made of wood, plywood and plastic.

Plunge circular saw is a mobile saw blade. The cutting edge of the tool is lowered into the center of the workpiece, starting from this cut, perform the through-holes.

Important! With the ability to adjust the cutting depth with high accuracy, it is possible not only to carry out through the cut, but also to perform straight or curly trough grooves and crevices.

How to choose a circular saw: The basic parameters of the instrument

Before you use the circular saw should examine its technical parameters, which play an important role in the effective operation of the device. The first is the power tool. It is directly connected with the saw blade diameter. The higher it is, the stronger must be the machine.

The more powerful the engine, the greater the force is transmitted to the area of ​​attachment to the drive shaft. Powerful devices are characterized by a stable operation, they are capable of withstanding the high frequency of rotation of the disk, which allows to handle denser materials. Stationary saws can have a capacity of 800 watts.

Useful advice! The higher the score, the overall and massive tool when working with who will need some experience.

The next important criterion to be considered when choosing a circular saw, a rotational speed of the disc. The larger it is, the easier it is to work with the tool. High speed drive facilitates the handling of dense materials, promotes a cleaner line of cut reduces the likelihood of jamming of the blank disc.

Note, however, that high speed contributes to the temperature at the point of the cut, so when cutting the laminate or plastic blanks can be fused edges. To work with such materials suitable tool in which you can adjust the amount of disk rotation speed.

Scope, structure assembly steps. Circular saw from grinders and circular saws. Selecting elements and independent manufacturing devices.

Disc diameter directly affects the depth of the cut. The product 160-mm depth of cut performs 4.5-5.5 cm, 190 mm - 6-6.5 cm, 230 mm - 8-8.5 cm. Both parameters affect the choice of thickness of the workpiece, which tool can handle. The higher the diameter of the disc, the more powerful engine is required for the saw. It should also be borne in mind that the saw can cut at an angle of 90 or 45 degrees. For the latest version of the depth of the cut will be less.

If the device can adjust the cutting angle, focusing on the quality of the base plate disposed thereon calibration and fasteners. Changing the position of the disc to be performed easily, thus it is necessary to ensure high reliability of fixation, no backlash.

Accessories for circular saws its additional features

When selecting a circular saw it is important to pay attention to the protection, which is equipped with a tool.

To replace the blade need to lock the spindle. This can be done manually by means of two keys. A more convenient alternative is the use of a special button, which is available in some models.

For the safety of the use of circular saws must be equipped with protection against accidental launch. Necessary function that facilitates convenient and efficient operation of the device is soft-start option, allowing the disk to rotate at low speed, accelerating gradually. It also increases the period of operation of the electric motor, prevents the formation of large inrush current at startup.

As the numerous reviews, circular saw, having the possibility of maintaining a constant engine speed, provides the smooth cutting inhomogeneous material. The apparatus does not decrease the traction in the event of contact with the disk over the solid portion of the preform.

Important!The presence function of maintaining the speed of the engine requires the use of a specific reserve of power.

Function necessary for normal operation of the tool is durable protection device overloading, through which the saw is automatically switched off in case of overheating the device or a sharp jump voltage.

After stopping the engine there is a high inertia disc rotating at idle, which lasts 1-2 minutes, which is sufficient for applying injury. To exclude such a possibility exists electrodynamic brake option. However, even the existence of such a function is unable to instantly stop the motor, the inertia of which will create a kickback. Effective for this use slip clutch.

Useful advice! For professional use is better to buy a universal stationary circular saw with a jointer.

How to choose the right drive for circular saws

Saw blade for a circular saw is primarily determined by the peculiarities of the tool. This takes into account the size and diameter of the planting member.

Useful advice! A quality drive for the saw is marked on the surface of the article, which specifies the diameter, landing, the number of teeth, cutting width, type of material being processed, speed and direction of rotation element.

Purpose of the saw blade determines the number of teeth. The product with a small number of them will provide a high rate of cut, thus completing a dirty propyl. To create a clean cut during sawing workpieces of solid materials in wood saw blade for circular saws must have a large number of teeth.

For cutting solid wood and decorative plywood sheets should choose products that have 50-60 incisors. For cutting wood along the grain enough disk 15-25 teeth. For the dissolution of the board, you can use the product with 10 cutters. Versatile option that is suitable for most purposes, a disc with 40 teeth. Plastic and non-ferrous metals should be processed article having a cutting edge 60.

Equally important is the tooth configuration. Straight elements is quick and clean propyl. For different direction of the cut, you can use a disc with alternately beveled cutters. For cutting plastic, non-ferrous metal plates and better purchase products with flat trapezoidal teeth which prevent splitting of the upper layer material.

For workpieces of different hardness may be used with the combined disc cutters, which combines elements of a different shape sharpening. They facilitate the preparation of clear cutting edge at high speed. Cutting the laminate best solution is to choose a disk with alternating concave and triangular teeth. If the workpiece comprises a cement admixture or nails, use an element with flat teeth equipped bevels with wide backs.

Quality on the disc has a smooth surface with visible light on divergent circles, which is the result of grinding. On the product can be disposed radial slots, which reduces vibration and noise.

Specifications of the circular saw guide

To perform correct and accurate machining a workpiece using an additional device for a circular saw as a bus. Due to such guide provides an efficient, easy, and safe operation of the device. With the tire can be carried out the longitudinal and transverse cuts, adjust the parameters of the workpiece, producing multiple trimming elements.

Tires for circular saws come in single- and double-sided, symmetrical and asymmetrical. There are also non-standard models, by means of which the workpiece can be processed nonstandard configuration complicated. Based on the method of use, the guide can be divided into two types: universal and specialized. The first option is suitable for all kinds of drink, and the other solves a number of problems on a particular professional equipment. These guides can work only with circulating saws.
