45. Uncomplicated start in a new technology or reasonable production extension Arguments pro:  lower manufacturing costs (see example cost accounting)  lower initial investment  cost effectiveness even in one production shift  output peaks can be worked off in-house, thus no need for outsourcing, no logistic delivery problems  installation of a more effective system for rise in output for meeting new material processing requirements  comprehensive service from one source, servicing machines of several manufacturers. We are your partner for service, modernization and resale!

46. Arguments con:  higher energy costs for older lasers and machines and higher maintenance costs  no guarantees like with new systems  parameters differ from initial performance  machines are not state-of-the-art But, Laser System Deal offers, if desired, machine overhaul and maintenance, and also production warranty for 2000 hrs. or 6 months!

47. We do everything necessary to make your cutting system reliable. Have confidence in us, a business partner whose Service Technicians have installed more than 150 machines! We can improve your laser processing results by:  replacing mechanical parts and optice  reworking of all the NC-axes  cleaning and painting  running acceptance tests You will produce higher quality after the Laser System Deal service!

48. Qualification brings efficiency, efficiency brings profit Why training?  economic, laser specific PC-programming  saving on material and cutting time  application optimization  maintenance and problem finding by your own personnel  the operator masters the machine after being trained by us Your operator identifies himself with the job and works on his own! www.laserdeal.com

49. Conclusions n Laser technology has matured and shows continuous rapid growth n Proven tool for modern industrial sheet metal fabrication n Precision and quality n Beneficial side-effects reduce costs Laser technology for higher profit
