DOWN MILLING [6 records]

Record 1 2015-04-23

English

Subject field(s)
  • Milling (Machine-Tooling)
  • Machine-Tooling (Metallurgy)
CONT

Knee-and-column-type milling machines. Knee-and-column type machines, in the horizontal version, have the spindle mounted in the column at a fixed height, and have the capability of positioning three sliding motions. Vertical motion is obtained by sliding the knee member up and down on the central stationary column.

OBS

The terms "knee-and-column (-type) machine", "column and knee (type) machine" and "column-and-knee-type machine" are often used for this concept when the context demonstrates that they refer to milling machines. Otherwise, the other terms are used.

Key term(s)
  • knee and column miller
  • knee and column type miller
  • knee type miller

French

Domaine(s)
  • Fraisage (Usinage)
  • Usinage (Métallurgie)
CONT

Fraiseuse à console mobile. Elle est encore actuellement la plus répandue parmi les petites machines; la table de travail est à mouvements croisés et se déplace horizontalement sur la face supérieure d'une console qui est fixée à la face avant du montant (du bâti) par des glissières verticales.

CONT

From the milling separator, the grain passes to a gravity separator. This machine separates materials that may be similar in shape and size but that differ in specific gravity, such as wheat and small stones. Uncleaned wheat is "floated" on a metal screen which is oscillating rapidly. The grain moves down the sloping screen to the outlet while the stones are propelled toward the head of the screen by the oscillating movement, and collected separately. Although only a very small percentage of stones may be present, their removal is important since they cause extensive damage to processing machinery. Also, if they are ground along with the wheat, the undesirable fine mineral matter will end up in the flour.

CONT

Du séparateur de mouture, le grain passe au séparateur-aspirateur qui en élimine les matières inertes dont la forme et les dimensions peuvent être celles du blé, mais qui sont d'un poids spécifique différent, comme le blé maigre et les petites pierres. Le blé non trié «plane» sur un tamis métallique qui est animé d'un mouvement d'oscillation rapide. Tandis que le grain suit l'inclinaison du tamis, les pierres sont projetées vers la tête de celui-ci par le mouvement oscillant et elles sont recueillies séparément. Bien qu'il n'y ait que très peu de ces pierres, leur suppression est importante en raison des dommages importants qu'elles causeraient aux machines de meunerie. De plus, si elles étaient moulues avec le grain, les poussières minérales indésirables se mélangeraient à la farine.

English

Subject field(s)
  • Milling (Machine-Tooling)
OBS

Milling machines are made in a great variety of models of various sizes and power capacities, and may be classed broadly as either standard or special. Standard machines may be further classified, according to structure, as knee-type or bed-type.

OBS

Knee-and-column-type milling machines... : Machines with a vertically mounted spindle generally have a fourth sliding motion which is up and down in the same direction as the knee.

English

Subject field(s)
  • Milling (Machine-Tooling)
CONT

This device, when engaged, eliminates the backlash(play) between the nut and the table leadscrew permitting the operation of climb(down) milling... Two independent nuts are mounted on the lead screw. These nuts engage a common crown gear which in turn meshes with a rack. Axial movement of the rack is controlled by the backlash eliminator engaging knob located on the front of the saddle. By turning the knob "in", the nuts are forced to move along the leadscrew in opposite directions, removing all backlash.
