Steve Randerson, Production Manager at Boxtrees Precision Engineering Ltd, Halifax, UK was able to enhance overall productivity with a touch probe and non-contact laser tool setting system from Renishaw.
By employing a Renishaw OMP400 high accuracy touch probe and NC4 non-contact laser tool setting system on a Mazak Integrex 200-IV ST, Boxtrees was able to radically reduce non-productive setting in their CNC machining systems while improving component accuracy and consistency of cycle times.
Additional benefits to the company included better production scheduling and reduced need for post-machining inspection.
Boxtrees makes all the machined parts for a large range of educational machine tools supplied by sister company Boxford, along with other sub-contract work.
Mr Randerson explains that a detailed analysis conducted five years ago of their machining operations revealed that 40% of machine time was used in setting jobs.
Renishaw’s touch probes and non-contact laser tool setting system got them to their goal of 0%, helping the company cut costs by improving their operation.
Mr Randerson says that the majority of work happens in very small batches including single parts, but does not impact the productivity in any way.
The Mazak Integrex was fitted with the Renishaw systems when supplied and has been operating at Boxtrees for 11 months. This is one of three CNC machine tools in active use at the machine shop.
Mr Randerson has also created machining programs for over 200 different components, which can be machined in many different materials including mild steel, cast iron or aluminium.
Every one of these programs relies on Renishaw part setting and tool breakage detection macro routines to control the process, making the most of the flexibility offered by the Mazak multi-axis mill-turn machine.
Renishaw Oceania is the Australian operation of the Renishaw group.
