How to make your own grinding machine: instruction, description and recommendations
Modern grinding machines are equippedpowerful engines and 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 sharpened ends.
For the processing of metal objects are requiredPowerful devices 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 a tree
Make a simple wood grinderyou can even use your own 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 the grinding machinemetal by their own hands, it is more expedient to select an electric motor with a power of not less than 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 fixed at once. In this situation, the beam is mounted on the frame.
To adjust the position of the block,lever with a return spring. The driving shaft of the model should be at least 5.5 cm in diameter. 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.
Make a drum-grinding machine yourhands can be manual or electronic type. If we consider the second option, we should first of all make a frame of steel sheets. Next, the frame is placed on which the guides will be located. The next step is to start the electric motor. He must be located at the bottom of the frame.
Directly the mechanism of the tape position canbe in the side of the machine. Due to this, the working area of the instrument is significantly expanded. Casing in this case can be used plywood type. For greater stability of the machine you will need to install the legs. 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
Assemble the spindle grinder with your ownhands can only be using 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. The guides are fixed in a horizontal position.
After fixing the unit, the longitudinalplate. 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 make with a cam-shaped lunette a ribbonThe grinding machine with your own hands can be pretty fast. 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 by a smallsize. To protect the motor, many experts recommend using a casing. To fix the workpiece, you need a powerful support. Directly the lunette plays the role of the feeder. It should be fixed next to the leading shaft. The control units on the devices are installed differently. Many experts in this case are advised to select high-quality CNC, which are able to regulate the engine speed.
Devices with a horizontal arrangement of the guides
To assemble with your own hands a grinding machine withThe horizontal guides are a very difficult task. In this case, a wide frame is required. The unit must withstand heavy loads. Straight legs are used 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, gearboxes are often used. In order to install the side plates, a welding machine is required.
Models with vertical guides
To make your own grinding machine withvertical guides can be used by 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.
Shkif for her 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.
Mount your own grinding machine withlongitudinal rest may be different. Electric motors are most often selected with low power. Flywheels in this case are fixed at the bottom of the frame. 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 used for 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 lunette 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-contact bearings can also be madeown grinding machine. The advantage of these configurations is their versatility. The blanks in this case can be processed at different angles. Start the assembly of the machine with the installation of the bed. Steel plates are used for the working platform. It is more expedient to solder the guides horizontally.
Flywheels for them are installed in the lastqueue. 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 make the machine quitejust. 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 7kW and frequency at 50 Hz. Corner positions are used to adjust the position of the pin. The guides of the model must be fixed on the plate. For free rotation of bearings, ball type bearings are used. 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 the grinding machine yourhands? 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.
