Ranking of the best grinding machines for 2020

In our review, you will find a description of the best grinding machines. We will provide recommendations on which company to buy a product, how to choose the right one, consider the best manufacturers, popular models, determine their characteristics, and orient by price.

How do machines work?

Grinding removes some of the material from the workpiece to shape, model it according to your needs. Processing takes place with an abrasive wheel consisting of quartz grains, silicon carbide, carborundum.

In fact, grinding is an operation that requires certain tolerances, a high class of accuracy, complex measurements (longitudinal or angular), compliance with geometric dimensions (concentricity, parallelism, perpendicularity). Also, grinding is intended for surface finishing, removal of roughness, scratches.

Machine types

There are many varieties of grinding equipment. Here we will consider what it happens, define the criteria necessary when choosing the functionality you need, we list tips that will pay attention to mistakes that may occur during the purchase, which is not unimportant for the effective implementation of any project conceived by you.

1. Surface grinding

Thanks to the simple design of such a machine, consisting of a longitudinal carriage, it is very easy to operate it. Depending on the position of the abrasive element, two types of product are distinguished:

• In devices with a vertical attachment of the grinding wheel on the spindle, the workpiece moves in a straight line, adjoins the abrasive tightly. These machines are typically used for rough surface machining, although some models can achieve high accuracy.
• The active element of the tangential apparatus rotates horizontally, works along the edge of the workpiece, moves in a circular, pendulum motion. Such machines are used, as a rule, for high-tech processing of bell-shaped, inclined, mating surfaces, grooves, for performing complex profiles, intra-end grinding works.

Such equipment can be used in conjunction with other, turning, milling. The workpieces are positioned using a magnetic clamping plate, manually or mechanically moved. The product is equipped with a pump for automatic recirculation and application of coolant to parts.

Scope of use:

• stamps;
• guides;
• plates;
• conventional or piston rings;
• Press forms;
• pins;
• profiles for tools.

Sizes of workpieces can vary from 40-80 cm to 6 meters. The machine can work with a high degree of reliability on metal, wood, it is possible to install brushing brushes.

2. Cylindrical grinding

These machines can work with workpieces of various shapes, however, the part must have a central axis of rotation: cylinder, cone, ellipse, cam or crankshaft. Let's select several subtypes of aggregates:

• On a two-drum machine, the part rotates synchronously with the abrasive.
• The size of the part processed by the internal sander is always less than the width of the wheel.
• Centerless grinders work with small-sized, cylindrical products, their area of ​​application, bolts or pins. The mechanism consists of two circles that rotate in the same direction, a part is placed between them, without a clamp (therefore the mechanism is called "centerless"), which rotates in the direction opposite to the abrasive. The drive wheel is tilted at a certain angle, from 1 to 5 degrees, depending on the hardness, the size of the material to be processed.

3. Universal

One of the nicest machines with excellent performance. On these machines, you can grind at home the outer, inner surfaces of camshafts, crankshafts, cylinders, cones, liners.

The longitudinal carriage, included in the design of the unit, provides translational movement of the workpiece, and the hydraulic mechanism gives the wheel the opposite rotation. The characteristic of the processed products determines the speed of the shaft using regulators.

4. Special

These machines are used for parts with complex mechanical geometries that cannot rotate by themselves. A vertical spindle (sometimes called planetary) is built into their design, in addition to rotation, it performs a circular movement.

The machines are used to process gears, their profiles, threads, rolling cylinders, frame guides, brake pads, splines, bearings, turbine blades, aircraft landing gear.

The grinding wheel has many different shapes, grain sizes, and meets international standards.

5.With CNC system

Technological progress has led to the emergence of numerically controlled products on the market, for example, grinding and calibration. Such machines are used both in large-scale production and in small enterprises, they will help to make your project successful, have a number of advantages over conventional ones:

• unification of workpieces processing (top, front, bottom) on one machine;
• full automation, minimal operator intervention;
• the dimensions of the unit allow grinding large parts;
• magnetic clamps;
• improved performance, accuracy;
• with the function of turning on servo motors for each axis, which allows you to effectively position the part;
• automatic wheel condition monitoring;
• the ability to program Cartesian coordinates;
• air cleaning system from shavings, dust.

After studying this review, you yourself will be able to rank the popularity of models. Decide which equipment is better to buy for efficient work.

Where can I buy

You can buy inexpensive, low-cost novelties in electrical equipment stores, managers will guide you at an average price, tell you how much a particular product costs, and provide step-by-step instructions on working on machines of this type. You can also order them online, in the online store, with a guarantee of fast delivery.
