Use of wood milling cutter clamping

core drilling bits machining center collet suit most accepted ways folder, when used in the form of a cantilever. Milling process is sometimes possible to gradually extend from the wood milling cutting disc knife folder, so complete? Lost, so that the workpiece scrap the scene, its cause is generally between deposit is due within the toolholder shank outer diameter hole wood milling cutters film formation due to insufficient clamping force. Are generally coated with anti-rust oil when milling factory, if you use a non-water-soluble cutting oil when cutting the hole when the holder will be attached to a layer of mist film, sold the toolholder shank and are deposited on the film is, the holder is difficult to firmly grip the handle, the wood milling cutting wheel is working on outstanding loose? lost. So before being milling fixture, should first milling toolholder shank and the hole cleaned with cleaning fluid clean, dry and then carry out clamping.

The main purpose of wood mill cutter

Roughly divided into:

1. Flat wood milling cutter, rough milling to remove a lot of rough, a small area of the horizontal plane or contour finishing.

2. Ball milling, for surface finishing and semi-finishing; small ball small chamfer cutting disc can also irregular contour surface finishing steep-sided / straight wall.

3. Flat head with a chamfer wood milling cutter, do a lot of rough milling to remove the rough, but also the fine milling of fine smooth surface (as opposed to the steep surface) small chamfer.

4. Molding wood milling cutter, including chamfering, T-shaped wood milling cutter or knife called a drum type, tooth knife, within R knife.

5. Chamfering, chamfering shape and chamfer the same shape into a fillet and oblique chamfer milling wood cutting wheel.

6. T-type knife, can T-slot milling.

7. Tooth flap abrasive cutting wheels, milling a variety of tooth, such as gears.

8. Bark knife for rough milling of aluminum-copper alloy cutting design for fast processing.

The use of wood milling cutter in life

Shovel teeth molding wood cutting tct saw blade tooth back curve is generally circular curve made Archimedean spiral or circle with the wood milling cutter center offset, in order to ensure that the amount of change in a number of wood milling cutter teeth back after regrinding after a small angle . Archimedes spiral equation in polar coordinates is: R = C θ Where:? R-- radially; C-- constant; θ-- polar angle. Archimedes spiral tooth back angle at any point after the calculation according to the formula: Formula: R-- tooth back to any point in diameter; R '- tooth back at any point the first cutting disc derivative of the path; θ- - tooth back at any point of the polar angle. Be seen from the above equation, α changes with θ. Since the value of θ itself is large (close to 2π), and a smaller variation range (less than ε =), so the change amount α is small. According to calculations, in general, change α is not more than 1 ° 30 '. So, in fact, can not consider changes in the posterior horn. When using the arc center offset curve for tooth back curve, although the changed angle α to be bigger, but still meet the requirements of the wood end mill cutter. After milling angle α on the working drawings are usually the amount of K by shovel teeth for labels.
