METHOD OF WORK (BD Swindon)
Tapping new holes in the side of platens on Netstal Machine
Machine Id :-
(for crane read overhead crane or gantry)
- The platen area of the machine should be clear of any obstruction i.e. conveyors, chutes, boxes, hoses etc.
and the area should be clean and safe for our engineers to work.
- Adjacent machines may need to be covered to prevent contamination.
- Smoke detectors above the machine may need to be temporarily disabled. (Note :- If purging fumes do not set
off the sensor, then any fumes from the cutting process are unlikely to set it off)
Method of work for Drilling & Tapping
- Initial contact is established with client, and any induction completed.
- The mobile equipment i.e. power pack, working storage bench, trolley, drilling rig are off loaded at goods
- The equipment is transferred into the air lock.
- Our engineers park up and enter through reception, then through the gowning area.
- The equipment is recovered from the air lock and moved to the machine.
- Once in position connections are made from the power pack to the clients 16 Amp 3Ph+N+E electrical and air
- The platen is opened / closed to a pre-determined distance by the clients engineers.
- The drilling rig is lifted by our engineers (with the clients crane, if required) into its first position on
- Jacks / clamps are used to lock the drilling rig in place.
- The hole is drilled to the required diameter and depth.
- During the drilling operation it may be necessary to re-sharpen cutting tools, this can be done using our rig
equipment or the clients equipment but must be carried out by our engineers.
- The hole is chamfered and then tapped.
- The template is attached to the platen using the 1st hole as a reference.
- The metal swarf that is generated by the operation of drilling / tapping is contained as best as possible.
- The drilling rig is unclamped and repositioned for the next hole by our engineers using the clients crane if
- After all the holes required in the template are finished, the template is removed.
- The holes are degreased and lubricated if required.
- The drilling rig is lifted out of the machine by our engineers using the clients crane if required.
- After the work has been completed the machine is left clean and tidy of the metal swarf that was generated.
The swarf remains the property of the client.
- Inspection and approval by the customer.
- The equipment is moved into the air lock
- Our engineers exit through the gowning area.
- The equipment is recovered from the air lock and taken to goods in, where it is loaded into the van
- After signing out, our engineers leave the site.
Waiting time due to circumstances beyond our control is chargeable at £90.00 per hour.
Should there be any cancellation or postponement of work when the engineers have arrived on site, there will
be a charge of £900.00 per day plus any expenses incurred.
