12 best grinding machines

In everyday life and professional activities, we constantly use a different tool that needs sharpening. From the knife to the cutter, it’s more pleasant for everyone to work if the edges are smooth and sharp. Therefore, our experts have prepared a rating of the best grinding machines for straightening the cutting part of both conventional and specific tools. The material was compiled on the basis of numerous reviews and after a thorough comparison of the characteristics of the goods, which will help to choose proven equipment for various needs.

How to choose a grinding machine

Before starting to study the ranking it is worth considering how to choose a grinding machine in order to understand what some characteristics in the description indicate. Here are the main criteria to pay attention to:

1. Power. For household machines enough 150-250 watts. This is enough to sharpen a knife and garden tools. For professional use make machines with power up to 600 watts. From this indicator depends on the ability of the engine to withstand loads from clamping the parts to be sharpened and not to overheat at the same time.
2. The number of revolutions. Thin steel grind at low speed, otherwise it will overheat and release. Thick objects are sharpened at high speeds from 2000 rpm. In the case of carbide elements, a high rotation speed of up to 15,000 rpm is needed.
3. Landing diameter. Varies from 12 to 32 mm. The larger the shaft, the larger the circles allowed to install. Mounting a large circle on a small shaft is not allowed.
4. The diameter of the circle and width. These values ​​affect the size of the equipment being sharpened. Small parts (knives, chisels, chisels) sharpen on small and thin circles. Large objects (axes, scythes, choppers) need wide and large abrasive products. This will provide better edge smoothness and performance.
5. Security and convenience features. Sharpening machines are equipped with various devices for better performance and safety. For example, it can be a stand for an emphasis, and in some models also with a variable angle. Protective transparent screen covering the operator's eyes from the departure of small particles. Directional lights to better see the quality of sharpening. Tray for cooling and flushing tooling.

Understanding the main selection criteria, we turn to the consideration of the best grinding models from the rating, divided into categories according to the purpose of the equipment.

The best universal grinding machines

Universal machines are designed so that they can conveniently sharpen both small objects and large parts. These are the best apparatuses for everyday life, installation in a garage or in a small enterprise where wood or metal processing is carried out.

ELITECH ST 600C

Rating: 4.9

Well assembled apparatus with a metal body. Inside there is a 600 W motor, which will easily cope with tight clamping of parts and will not slip at the same time. A common shaft passes through the engine, on the edges of which two circles are set: on the left with small granules, and on the right with large ones. Both sandpaper has a diameter of 200 mm and a width of 2.5 cm. Abrasive elements are closed in a durable casing, and the master's eyes protect plexiglas screens with an adjustable position. The manufacturer did not forget about the backlight lamp on a flexible leg, which is easy to send to any point. The start button is rubberized and does not harm when pressed with wet hands.

In our opinion, the universal machine should be in the rating due to especially strong stops having reinforcement from the bottom. These are not simple plates, but thick slats that can withstand heavy loads. Their height is adjustable, and on the left there is even a recess for reliable positioning of the drills. According to the reviews it can be seen that the powerful grinding unit does not vibrate on the table, so the use is quite comfortable.

ZUBR ZTSHM-200-450

Rating: 4.8

A modern universal grinding machine with a compact body and two circles with a diameter of 200 mm. The rotation provides a 450 W motor and accelerates revolutions up to 2950 per minute. Equipped with a machine LED lamp on a flexible leg, folding glass screens and thin supports with a variable distance to the emery. For fixed fastening there are two holes in the bottom of the case. A model is packaged in a package with a Bison seal confirming originality.

In the reviews of the owners it is clear that the machine is characterized by increased stability and does not “run” on the table in a loose form. To do this, it has wide legs, stops that prevent the movement of equipment from vibration. This model is of the best rating for workplaces where it is often necessary to rearrange equipment for clearing a place or remove it for storage. With subsequent use of the model will not have to attach to the table.

VORTEX TC-400

Rating: 4.7

Simple domestic model with air-cooled motor. The grinding unit consumes 400 W and develops the speed of 2950 rev / min. The device works with large circles of 200 mm in diameter and 2.0 cm in width, but is endowed with a specific landing shaft with a size of 16 mm, so buyers respond that finding a snap under it will be more difficult. The budget impact on everything - except for the backlight, the device has nothing. None: stops, bath, protective screens. But the lamp bracket is long and flexible, which allows you to bring it to any side and see the workflow well.

Our experts recommend this model from the rating as the best for the garage. On rough sandpaper, you can quickly tinker with an ax, a cleaver and a chisel, and sharpen knives, drills and garden tools with small ones. The cost of the machine is two times lower than similar products from other manufacturers, which will not create problems for the family budget.

Wert GM 0315

Rating: 4.7

Sharpening machine with two small stones with a diameter of 150 mm and a width of 16 mm. They are put on a shaft with a fit of 1.27 cm. A 250 W motor starts up rotation, but the speed is at the level of professional equipment and is 2950 rpm. The start key is protected from water ingress and there are two stops with a variable distance. Protective shields with an expanding form that better blocks the path of flying particles. In the reviews, the owners note the absence of stone beats.

The sharpening model is listed as the cheapest in the category. But the affordable price affects the size, so the equipment is not suitable for sharpening large tools and accessories. Since buying it only for dressing knives in the kitchen is not profitable, our experts recommend that argon welders who constantly need to sharpen the tungsten needles of non-consumable electrodes pay attention to it. A circle with a fine abrasive provides a perfect cone that promotes neat seams. On a rough stone, it will be possible to process the seam itself on a pipe or a small plate.

The best machines for sharpening drills and knives

Sharpening knives and drills on an ordinary sharpener requires skill and skill. The blade of the kitchen equipment can simply be grinded or burned, and the drill bits will remain blunt due to the wrong angle. Therefore, manufacturers produce machines with already prepared slots, where you just need to insert a snap, and the machine will do the rest. Here is the ranking of the best grinding models of this type.

Diold MZS-0.2

Rating: 4.9

Electric machine powered by a single-phase network 220 V, consuming 200 watts per hour of work. Despite its compact dimensions and low power, it develops a rotational speed of up to 5,500 rpm, which makes it possible to effectively sharpen carbide steel on drills. In order to fasten the snap-in, a convenient chuck is provided, as well as a centering system to ensure uniform passage of the edges. A nest with a horizontal entrance provides access to the stone for sharpening, and placing the cartridge in the vertical hatch will remove burrs.

Proven sharpening system, sold for several years and tested by users. According to reviews it is clear that the machine is reliable and productive, but you can buy circles on it not everywhere. Therefore, for large amounts of work is not suitable. But our experts recommend to pay attention to it to those who need to sharpen drills with a diameter of 13 mm. Not every model is able to accommodate such a snap, but this one is designed to work with such dimensions, for which it won a place in the rating.

Sturm BG6010S

Rating: 4.8

Sharpening unit with engine power of 100 W, developing 6700 revolutions per minute. The unit has a compact size of 30x7.5x11 cm and weighs only 1.8 kg. The manufacturer interestingly implemented an attachment fastening system. The model has three units for holding drills, knives with scissors and chisels. At the heart of the design is one stone, and the blocks are joined to this part of the body alternately. In order not to lose unused parts, mounting is provided on the sidewalls. On the module intended for chisels and thick axes, there is a degree switch that provides sharpening at different angles. Users speak of it as a quiet machine without vibration.

Experts put the machine in the top ranking thanks to a secure retention system for a large tool. When sharpening chisels or chisels, a snap is fixed by a magnet that prevents the object from being pulled out of hands.

Patriot BG 100

Rating: 4.7

American brand assembled in China. Endowed with a capacity of 96 W and accelerates a circle with a diameter of 56 mm to a speed of 1350 rpm. 180 grit of stone provides accurate edge grinding and sharpness. Rubber cable is resistant to negative temperatures and retains its flexibility for a long time. The machine is made of plastic, which reduced the cost and weight. By analogy with other brands, it has three rearranged blocks for fixing various items. The module for chisels and chisels has a screw for adjusting the position of the inclination, but without designation of degrees, so the device should be adjusted to the eye. In the reviews, the owners note that this is an exclusively domestic model, because the circle will quickly be erased from frequent use.

Experts recommend a multifunctional grinding machine from our rating for sharpening manicure accessories. Since the manicurist's tool often gets blunt, this machine, weighing only 1 kg, will always help to have a sharp cutting edge, and the stone will last a long time thanks to working with short blades.

The best chain sharpening machines

Sharpening machines for working with saw chains will be useful to those who regularly use chainsaws or their electric and battery counterparts. The sharp chain will provide high performance and save fuel or save the electric motor from overheating.

CHAMPION C2001

Rating: 4.9

Professional grinder with a power of 230 W, delivering 3000 rpm. It is equipped with a stone 14.5x2.2 cm, mounted on a straight shaft from the electric motor. The drive is located on a metal bracket with a drop-down top. On the horizontal metal frame there is a vice slot for clamping the chain. Rotating emery is covered with a transparent casing for proper visibility and safety. Users in the reviews draw attention to a convenient scale, on which it is easy to adjust the degree of stone impact on the teeth of the chain.

The equipment was included in the rating due to good equipment and high performance. It is worth paying attention to the teams of lumberjacks who need to sharpen chains in large quantities.

Vihr SZC-200

Rating: 4.8

Domestic product with a power of 200 W and a rotation speed of 6000 rpm. Equipped with a circle with a diameter of 100 mm with a thickness of 3.2 mm. There are three adjustment screws for clamping the chain and adjusting the angle of the motor unit. Perforation for heat sink is provided on the back of the compartment. Although there are some gaps in the design, according to the reviews of the owners, they can be easily eliminated and the equipment can be adjusted to work correctly.

The machine is listed as one of the cheapest in the category, compared with peers. We recommend this machine for those who need to independently harvest a large amount of firewood for heating, and therefore the chain on the chainsaw regularly needs to be edited. Due to the low cost of the product will quickly pay off.

CHAMPION C2000

Rating: 4.7

The sharpening device for saw chains with a simple design and weighing only 2 kg. The rotation is provided by an electric motor of 85 W, spinning sandpaper up to the speed of 4500 rpm. The thickness of the stone 4.5 mm allows you to sharpen even professional chains with a large pitch. According to reviews, it is noticed that the machine works very quietly, and its clamp reliably holds the inserted chain. But users do not have enough light, so you have to take care of this separately. Even the model does not have a full-fledged handle, but only a small ledge - the pressure, in fact, is carried out behind the headband of the engine.

The experts decided to add this grinding machine to the rating as another affordable option for people who often use a chainsaw at the cottage. The machine will allow you to comfortably sharpen the chain, and not spend half a day on using the file. It is especially good with it to change the sharpening angle from 30 degrees to 10, which most owners noted.

The best machines for sharpening saw blades

Owners of power-saw benches, circulars and other equipment with cutting steel discs regularly need teeth straightening, for which purpose grinding machines of a special design are used.

Enkor Korvet 472

Rating: 4.9

Goods from the Russian brand with a powerful 370 W motor and a belt drive. Asynchronous motor rotates a stone with a thickness of 2 mm and a diameter of 100 mm at a speed of 3500 rpm. The machine is placed on a solid basis and weighs 40 kg, so when working, it does not rattle and does not travel. The scale on the turning part helps to adjust the desired angle for sharpening. The reviews noted that the machine is not heated and is suitable for operation all day.

Experts put the machine in the rating as the most convenient. The disk is securely fixed on the bracket, which moves along two guides. The gap here is minimal, which provides high precision sharpening. When moving from one tooth to another disk is blocked from reverse rotation, so as not to spoil the cutting edge by random movement. We advise this grinding unit for a large wood sawing shop, where the operator will be comfortable with the work for a long time.

Kalibr Master EZS-110DM

Rating: 4.8

Russian-Chinese grinding device for disks with a rotational speed of 5300 rev / min. At the same time, the machine consumes only 110 W, since a rectifier is provided inside, and the device continues to operate at a constant current. The small dimensions and weight of 5 kg are due to an extraordinary design with a rotary guide, on the axis of which the disk is placed. The stone is securely hidden in a plastic casing. The user's eyes are closed with a transparent screen through which it is convenient to monitor the process. Owners recommend in reviews to train first on a damaged disk to learn how to accurately set the angle of adjustment, because here it is very difficult.

The model is listed in the rating, because it is five times cheaper than analogs.But since there are backlashes in the design, it is optimal to use it for sharpening disks for sawing rough wood. This will help to easily restore tool sharpness and accelerated work.
