Отличия лазера от фрезы очевидны — это скорость работы, ширина реза и механическое воздействие на деталь.
Лазерный комплекс осуществляет бесконтактную резку в отличие от контактной раскройки фрезерного станка, то есть, не существует механической связи между заготовкой и обрабатывающим инструментом. Во фрезерном оборудовании существуют механические нагрузки от работы фрезы. Нагрузка при фрезеровании происходит через «голову» и передается на всю механическую конструкцию (передачи, шестерни). Вес «головы» равен 5-6 кг. Более мощные двигатели, чем у лазерного комплекса двигают каретку, на которой расположена фреза.
Параметры скорости резки лазером быстрее в два-три раза, по сравнению с фрезерным комплексом. Возникает сложность быстрого разгона шестикилограммовой фрезы до скорости 100 мм/секунду. У лазерных комплексов таких проблем нет. Он работает на гораздо более высоких скоростях холостого хода, поскольку вся оптическая система лазерного комплекса весит не больше килограмма.
Ширина реза лазера составляет доли миллиметров, фреза от 3 и более мм. Интересный момент, если приобрести дорогой производственный фрезерный станок, который обеспечит точно такую же скорость и точность, как и лазер, то он будет стоить гораздо дороже всего лазерного комплекса.
Но при сравнении присутствует еще и психологический момент работы на оборудовании для резки материала. В данном случае фрезерный станок имеет преимущество. Фрезер — это механическая обработка, более доступна человеку с психологической точки зрения. Понятен процесс обработки, виден контакт фрезы с материалом. Лазер не ассоциируется с простыми вещами. Он существует как нечто сложное для понимания.
Преимущество трехмерной фрезы пред лазером заключается в следующем: лазерный луч имеет строго перпендикулярное направление, может резать лишь поверхности, которые расположены перпендикулярно по отношению к лучу. Фреза, в свою очередь, позволяет стачивать поверхность под углом, что важно при изготовлении форм для формовки и других специфических объемных моделей. Но раскроенный материал на фрезерном комплексе иногда требует дополнительной обработки края реза.
