Brass removed by drilling - computer numerical controlled (market for)

The activity generating the emissions is market for brass removed by drilling, computer numerical controlled. The reference product is brass removed by drilling, computer numerical controlled. This is delivering the service of brass removed by drilling, computer numerical controlled. Drilling uses a rotating cutting tool (the drill bit) to remove material from the work piece and it predominately uses the front end for cutting. It is applied for shapes like circular cavity or holes. The process is conventional, meaning that it is controlled manually and needs constant supervision. The process is computer numerical controlled, meaning that it operates autonomously once programmed. This dataset represents the drilling of 1 kg of brass. The service includes materials input, production infrastructure, machinery and electricity consumption. Maintenance and tool (bit) replacements are not included. Degreasing is not included and has to be added if necessary. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary market activity.
