The demands of complex rubber molds have spurred moldmaker Micro Moules Inc. to purchase four new machining centres and a high-end five axis machine over the last three years. Delivery of the five-axis Mikron machine from Switzerland was expected in November. (Mikron is represented in Quebec by Ferro Technique Ltd., Montreal.)
“About one-third of our business is focused on molds for rubber gaskets. These shapes are very complicated, and often required multiple set-ups for each mold. With the five-axis machine we hope to decrease set-ups to two,” explains Micro Moules engineer Alex Matug.
For high speed machining and large molds, Micro Moules purchased two Takumi V22A machines (table size 2200 mm x 800 mm) within the last year, and a Matsuura MC-1000 VF.
The company uses software from Depo (Oakville, Ont.) for post-processing of CAD data to output NURBS part programs for the CNC controls. Matug says this system is about four times faster than the previous set-up for generating toolpaths.
He notes that many components must work together to maximize the abilities of a high-speed machine. In Micro Moules’ case, one machine is capable of up to 400 inches per minute feed rate, but is restricted to 100 ipm by spindle speed and lack of appropriate cutting tools. As well, says Matug, “With high speed machining, the set-up sometimes takes longer than the machining.”
