What work can be done with a hand mill?
With the router it is possible to mill the grooves, various recesses, grooves in the details of wood. These recesses may extend beyond the edge of the part, that is, be open. You can mill closed recesses. They can be placed across or along the layers of the tree. Such grooves and notches serve to perform constructive functions. They are in most cases included in the design of detachable or one-piece connections of elements.
Edge milling is carried out using a hand mill. It is used when making eaves, platbands and other profile elements. Edge milling is used in the manufacture of furniture and the creation of various decorative parts made of wood.
Perform milling complex contours with machined edges. At the same time make exquisite works of art of wood. In such works, templates are used with which you can copy complex forms that are repeated many times in many elements.
Using a router, create curved contours. So do the holes and grooves for locks, sheds and other structures.
The main cutting element of the device is the cutter. It consists of a cylindrical shank and a working element having a cutting edge.Back to table of contents
What are the cutters?
For processing of soft wood using cutters of tool steel. For hard rocks, cutting elements made of hard alloys are used.
In order for the workpiece to acquire any shape, it is necessary to ensure the correct position of the cutting element relative to the part in all three planes.
In order to ensure the correct position of the cutter in a vertical position, an immersion mechanism is used, by means of which the device moves with the cutter along vertical guides. The immersion mechanism stops the cutter in the right place vertically.
The correct position of the cutting element in the horizontal plane is achieved in different ways. Guide bearings can be used that fasten to the torch. Also use a guide sleeve, which is fixed to the support surface of the manual router.
When a milling cutter with a guide bearing is in operation, this bearing moves along the edge of the workpiece or template. This leaves the necessary distance between the workpiece and the cutter. Cutting elements that process the edges of the workpieces and include a guide bearing in their design are called edge ones. They are used to process the edges of parts.
Edging mills can be profiled. They give the edge of the blank a shaped profile that performs decorative functions. Cone is used to cut the edge at an angle of 45 °.
With the help of a disk cutter in the parts, a horizontal groove is made, which may have a certain width and depth. With the help of a faltsev cut quarters. Baking is used to create decorative edges of the elements.
Groove cutters that do not have guide bearings are used for machining parts anywhere. When working, it is necessary to use special tools that ensure the correct position of the cutter in the horizontal direction.
Rectangular grooving cutting elements are used most often. With their help, perform grooves for detachable or non-detachable connection parts.
A fillet cutting element performs semicircular notches or grooves for decorative purposes. The V-shaped milling cutter performs deep grooves with vertical edges. The L-shaped cutter is used in the manufacture of furniture to create spike joints.Back to table of contents
How to secure the cutter in the chuck of the bit?
It is possible to establish a mill in the engine which was taken from a bed. You can perform work in the engine, located in the frame.
Types of cutters.
The installation of the cutter is performed as follows:
- Manual cutters lay to the side.
- Fix the spindle with a wrench.
- Tighten the collet clamping nut.
- In the clamping collet set the shank of the cutter.
- Wrench clamping nut with a wrench.
When working as a manual mill on a tree, it is necessary to set the depth of milling. When setting the desired depth, when the cutter reaches this level, the limiter will rest against the stepped stop and its further deepening will be impossible.
The rotation speed of the cutter is usually high, over 10,000 rpm. The faster the speed of rotation of the cutter, the better the cut is obtained. But too high speeds of rotation can lead to charring of the surface or damage to the mechanism. Therefore, the rotation speed is set depending on the diameter of the cutter and the strength of the wood. So, for a mill with a diameter of 10 mm, its rotation speed should be 20,000 rpm. The harder the wood, the less should be the number of revolutions.
If the router worked for a long time at low revs, then it should be turned off for a few minutes in order for the engine to cool down.
The direction of movement of the cutter on the tree is the opposite or passing. With oncoming movement, the edge of the cutter moves in one direction with the movement of the device. With a simultaneous movement of the edge moves in the direction opposite to the movement of the device. The correct and most secure is counter milling on wood.Back to table of contents
How do milling?
Milling machine with a copier for making balusters with their own hands.
Materials and tools:
- manual frezer;
- wood harvesting;
- flat base;
- guide bearing;
- power supply;
- protective overalls;
Milling is performed with the help of devices that ensure the correct position of the router. Before starting work, you must perform the following operations:
- Set the required number of revolutions of the engine.
- Establish the necessary depth of milling by means of the immersion limiter.
- Fix guide bearing in order to establish the desired trajectory of the cutter on the tree.
- Set the slice thickness to no more than 3 mm.
To work with a manual wood milling machine, you need to install the device on a workpiece that is going to be processed or on any flat surface.
After that, the guide bearing is pressed against the guide edge. Then turn on the engine. Begin the dive cutter, and then begins a stable movement of the router along the line defined by the guide bearing.Back to table of contents
Little table for a manual mill.
During the work as a manual frezer it is necessary to observe the following security measures:
- The device is installed when the electrical cord is unplugged from the outlet.
- During the work you need to firmly hold the tool in your hands, to prevent the device from falling.
- The workpiece must be secured firmly.
- 4. When processing wood, care must be taken to avoid a kickback, that is, a position where the cutter hits the wood. As a result, the cutter can jump out of the hands or the device will fail. A person may be injured.
- To avoid a kickback, it is necessary to firmly hold the router in the hands, firmly press it against the workpiece and smoothly move the device. The thickness of the cut wood should be no more than 3 mm.
- When performing milling must wear protective overalls.
- Work must be carried out in a respirator to protect the respiratory organs from wood dust.
At observance of all the rules for the implementation of milling work and safety, work on milling wood with a manual mill will be carried out qualitatively and competently.
