Brown & Sharpe Single Spindle screw machine. Model #2 Square Base, four-slide machine. 1 1 ⁄ 2 cap or 1 3 ⁄ 4 Air Feed.. Screw machines, being the class of automatic lathes for small- to medium-sized parts, are used in the high-volume manufacture of a vast variety of turned components.
Sometimes, when vibration problems are too much of a financial prejudice, experts can be called upon to prescribe, after measurement and calculation, spindle speeds or tool modifications. Compared to the industrial stakes, commercial solutions are rare. To analyse the problems and to propose solutions, only few experts propose their services.
Fay automatic lathe [1] The Fay automatic lathe was an automatic lathe tailored to cutting workpieces that were mounted on centers (tools with pointed ends to accurately position a center-drilled workpiece about an axis, either directly or by using a mandrel ).
A precise description of what a machine tool is and does in an instant moment is given by a 12 component vector relating the linear and rotational degrees of freedom of the single work piece and the single tool contacting that work piece in any machine arbitrarily and in order to visualize this vector it makes sense to arrange it in four rows ...
A vertical lathe is a lathe where the axis of rotation is oriented vertically, unlike most conventional lathes which are oriented horizontally. Many of them are frontal lathes , meaning they do not have the option of mounting a tailstock , but vertical lathes can also be implemented as parallel lathes .
The introduction of CNC-controlled lathes has provided a practical, everyday solution via automated CSS Machining Process Monitoring and Control. By means of the machine's software and variable speed electric motors, the lathe can increase the RPM of the spindle as the cutter gets closer to the center of the part.
A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles.
