Radial Drilling Machine types
Radial Drilling Machine
When it comes to mechanical machining, radial drilling machine is used for all functions such as drilling, counter boring, spot facing, lapping, screwing reaming, tapping and boring. Radial drilling machines work well with a variety of material such as cast iron, steel, plastic etc. Drilling machines hold a certain diameter of drill (called a chuck) rotates at a specified rpm (revolutions per minute) allowing the drill to start a hole.
Radial drills are of three types. With the plain radial drill, the drill spindle is always vertical, and may not swing over any point of the work. The spindle in the half-universal drill may be swung over any point of the work and it may swing in one plane at any angle to the vertical up to complete reversal of the direction of the drill. And the spindle in the full-universal drill can be swung in any plane at any angle to the vertical.
The specialty of radial drilling machine is that they are of robust construction and are designed for heavy duty drilling. The machines need to have all cast parts of fine close grained grey iron casting machined to close tolerance. They have to be subject to rigid inspection at all stages of assembly to ensure accuracy. Superior machines are known for their Grade 1 accuracy. Radial drilling machines having oil bath gearbox and hardened gears tend to have a very long life. The rotation and easy sliding of gears in bearings gives very high reliability. Gears are internally splined and shafts are externally splined.
The radial drilling machines can have 32 mm 125 mm drilling capacity; mt-4 spindle nose; head stock is bored on toss imported boring machine; double column grinded by wmw german-make cylindrical grinders; and has 2425 standard accuracy. The smt 40/1000 dc radial drilling machines are useful in almost every tool room as well as maintenance purpose.
Our radial drilling machines have heavy-duty high precision all-geared drill head with forged steel gears and toughened spindle.
Face milling and keyway milling operations is made easy thanks to the automatic vertical movement of arms as well as horizontal automatic movement of main spindle head. Accurate inclined drilling is made possible with arm lilting at 360 degrees.
A lot of time is expended due to the changing of the position of work on a machine. In a radial drill machine, the drill table is placed on a solid foundation for holding very heavy work. When a piece of work is secured on the drill table, the drill spindle may be placed over any part of the work without moving the latter.
