Frequent problems on CNC grinding machines. CNC grinding machines are complex systems for carrying out sophisticated machining tasks. The number of components involved and the countless configuration options inevitably lead to an equally high number of potential errors, which may crop up individually or in combination. Some of these problems are outlined in the following. The actual range

Electrical Control Monitoring System (ECMS) Following the rigorous duties these machines perform, staff take them offline for up to eight hours daily for cleaning, inspection, and repair. Mechanical failures are inevitable for primary, secondary, and tertiary crushers and given the severity of impact that components absorb, it is not uncommon for small, undetected problems to rapidly
The primary value of thermographic inspections of electrical systems is locating problems so that they can be diagnosed and repaired. "How hot is it?" is usually of far less importance. Once the problem is located, thermography and other test methods, as well as experience and common sense, are used to diagnose the nature of the problem. The following list contains just a few of the
Process parameters (electrical and nonelectrical) have significant effects on MRR. Higher MRR can be achieved at high discharge voltage, peak current, pulse duration, and duty cycle. However, other desirable process performances such as TWR, surface finish, and dimensional accuracy are also important aspects and taken into account in micro-EDM. (4.2) Material removal rate (MRR) = Weight

Electrical Equipment In Poor Condition: An 18-year-old worker at a construction site was electrocuted when he touched a light fixture while descending from a scaffold for his afternoon break. The source of the electricity was apparently a short in a receptacle, but examination revealed that the electrical equipment used by the contractor was in such poor condition that it was impossible to
Planing machines and moulders are used for longitudinal processing of products in solid wood, panels such as MDF, plastics or similar materials and are, therefore, generally the centerpiece of production facilities. This is where maximum value creation is applied to the work piece and quality and reliability are essential. Two aspects that WEINIG, as a world market leader, embodies like no

Deburring does not count as a core process in machining. On the contrary, it has up to now been considered a necessary evil. Again and again this has led to the machining processes being optimally coordinated, whilst the cost-effectiveness of the system as a whole suffered, owing to the fact that deburring was not taken into consideration as being part of the process chain right from the word go.

Machines can be portable, simple manual machines, or fully automatic with gauging depending on the application. Modern advances in abrasives have made it possible to remove much larger amount of material than was previously possible. This has displaced grinding in many applications where through machining is possible. External hones perform the same function on shafts. Process mechanics
