Speed Considerations for Ballscrews. There are two different speed factors to consider when it comes to sizing ball screws; characteristic speed and critical speed. The characteristic speed depends on the limitation of the bearing system, and what speed it can withstand. This is an industry standard for a variety of bearings, indicating speed ...

The side milling is the production of a flat vertical surface on the side of a work piece by using a sidemilling cutter. The depth of cut is adjusted by rotating the vertical feed screw of the table. Straddle Milling. When two or more parallel vertical surfaces are machined at a single cut, the operation is called straddle milling.

Precision machining is a subtractive process where custom software, engineered tools, and process steps are utilized on raw material such as plastic, ceramic, metal, or composites to create desired finefeatured products. Precision machining is often controlled by computer aided design (CAD) and computer aided manufacturing (CAM) programs.

Thermal drift at tool centre point (TCP) is caused mainly due to positional errors in feed drive system of machine tool. The important sources of these errors are frictional heat generated at contact areas such as ball screwnut, bearing races and balls. In addition to this, heat losses of motor also contribute resulting in thermoelastic deformation in feed drive system. The objective of the ...

A lead screw is a kind of mechanical linear actuator that converts rotational motion into linear motion. Its operation relies on the sliding of the screw shaft and the nut threads with no ball bearings between them. The screw shaft and the nut are directly moving against each other on a large contact area, so higher energy losses due to ...

Regular preventive maintenance (PM) of the ball screw system can ensure reliable, troublefree operation. The screw must be wiped off to remove debris and old lubricant residue and then replenished with new lubricant. The frequency for ball screw maintenance is determined by the duty cycle and environment in which the ball screw operates.

Form milling is the operation of producing irregular contours by using form cutters. The irregular shape may be convex, concave, or of any other shape. After machining, the formed surface is inspected by a template gauge. The cutting rate for form milling is 20% to 30% less than that of plain milling.
