How to make your own grinding machine: instructions, description and recommendations

Modern grinding machines are equipped with powerful motors and are able to perform a lot of tasks. In particular, they have the ability to process wooden objects of various shapes. Many modifications are used to strip rounded surfaces. Models with horizontal guides are often used for working with pointed ends.

For the processing of metal objects, powerful devices are required that have tight belts. It is rather difficult to make a belt grinder with your own hands. However, it should be borne in mind that there are various modifications that do not apply to complex devices.

Models for work on wood

You can make a simple grinding machine on wood with your own hands even without using an electric motor. In this case, it is more appropriate to consider the drum modifications. First of all, the bed is installed for the stability of the structure. Then the guides are fixed on it. They are necessary for fixing the workpiece. To the drum, attach the shaft with the flywheel. Due to this, it will be possible to rotate the structure. In this situation, the drum should be selected with a small diameter.

Devices for working on metal

In order to make a grinding machine for metal with their own hands, it is more expedient to select an electric motor with a power of at least 5 kW and a frequency of 55 Hz. Before starting work it is important to make all the measurements. In this case, much depends on the size of the metal blanks to be processed. After installing the frame, the guides are immediately fixed. In this situation, the beam is mounted on the frame.

To adjust the position of the block, a lever with a return spring is used. The driving shaft of the model should be at least 5.5 cm in diameter. The emery cloth should be selected broad. Flywheels are used to adjust the guides. If we consider tape modifications, then there will be additional rollers for the machine. They must be fastened over the bed.

Drum Modifications

Make a drum-grinding machine with your own hands can be manual or electronic type. If we consider the second option, we should first of all make a frame of steel sheets. Then the frame is laid on which the guides will be located. The next step is to start the electric motor. It must be located at the bottom of the frame.

Directly the mechanism of the tape position can be located in the side of the machine. This greatly expands the working area of the instrument. The housing can be used in this case plywood type. For greater stability of the machine you will need to install the feet. Carrier plate in the modification should be with a shield. After fixing it, it remains only to install the flywheel, which regulates the position of the guides.

Spindle models of machine tools

You can assemble the spindle grinding machine with your own hands only with the use of electric motors. Quite often, experts recommend selecting models for 5 kW. The main element of the machine is considered to be a spindle mechanism. It should be installed on a stand. Directly the guides are fixed in a horizontal position.

After fixing the unit, the longitudinal plate should be secured. On it will be stacked blanks. Screws are used to fix the stand. Rollers in the structure should be located on both sides of the spindle mechanism. The load-bearing plate in the structure must withstand heavy loads. To increase torque, shkify are used. In this case, the position of the guides is adjusted by means of flywheels.

Model with cam lock

To do with a cam lock the belt sanding machine with your own hands can be done quite quickly. Manual modifications are very rare. In this case, the engine should be selected with a power level of 5 kW and a frequency of at least 55 Hz. The grinding wheel should be installed on the working platform. Fixing it occurs on the frame. To adjust the position of the guides, flywheels are used as standard.

The tape in this case is selected a small size. To protect the motor, many experts recommend using a casing. For the purpose of fixing the workpiece, a powerful support is needed. Directly the lunette plays the role of the feeder. It should be fixed next to the drive shaft. The control units on the devices are installed differently. Many experts in this case advise to select high-quality CNC, which are able to regulate the engine speed.

Devices with a horizontal arrangement of guides

Gathering with your own hands a grinding machine with horizontal guides is a very difficult task. In this case, a wide frame is required. The unit must withstand heavy loads. The feet are used directly to fix the working platform. Guides in the model must be above the lower frame. The mechanism of the tape position is fixed near the electric motor. Also in these devices are often used gearboxes. In order to install the side plates, a welding machine is required.

Models with vertical guides

A self-polishing machine with vertical guides can be manufactured using a welding inverter. In this case, the tape should be fixed on the drum. The electric motor for the configuration itself is harvested with a power of about 7 kW and a frequency of 55 Hz. The beam of the model must be fixed firmly at the base of the machine.

The crochet for it is selected with a head. A small plate is required to stop the workpiece. Next to the guides, there should be a place for the roller mechanism. All this will allow you to easily change the position of the workpiece on the desktop.

Lathe machines

Mounted with their own hands the grinding machine with longitudinal lunette can be different. Electric motors are most often selected with low power. Flywheels in this case are fixed at the base of the bed. Bearings are used to adjust the pinion. The plate will be required for a machine with a steel stop. The bearing plate of the model is of a small thickness. The gearbox is most commonly used in the rack-and-pinion type. To adjust the position of the guides, you need a lever. Directly the lyunet is installed on the edge of the support beam. To fix it, you can use screws.

Modification with rolling bearings

With the help of rolling bearings, you can also make your own grinding machine with your own hands. The advantage of these configurations is their versatility. The workpieces in this case can be processed at different angles. Start the assembly of the machine with the installation of the frame. Steel plates are used for the working platform. It is more expedient to solder the guides horizontally.

Flywheels for them are installed last. The drive shaft in the structure must be under the frame. The mechanism of the belt position is installed near the electric motor. Fences are used for safe use of the machine. After fixing the flywheels, it remains only to secure the casing to protect the mechanism from dust.

Devices with sliding supports

With sliding supports, making the machine is quite simple. In this case, the guides can be installed in a horizontal position. The working platform of these configurations is mainly made of a small width. Direct support for the machines must be on the edge of the upper beam. However, the first thing to do is to make a frame for the instrument. For this, metal profiles are selected. Also it is possible to use pipes quite successfully. The upper beam is attached to the frame.

Electric motors are used with a power of about 7 kW and a frequency of 50 Hz. Angles are used to adjust the position of the crochet. The guides of the model must be fixed on the plate. Bearings of ball type are used for free rotation of bearings. The mechanism of the tape position is fixed near the electric motor. If we consider the classical model, then the drive shaft is installed under the guides. Thus, the maximum rotation of the spindle is achieved. To protect the operator during operation, fences are used. You can also install a pod on the edge of the working platform.

5 kW model

At 5 kW how to make a grinding machine with your own hands? They make such devices most often with a spindle mechanism. The upper beam of the models can be placed on the frame. Shkifs are most often used as a guide type. The belt positioning mechanism should be installed next to the motor. By the type of the upper blocks, modifications differ.
