To migrate from prototyping and one-off work to higher-volume jobs, Elmira, New York-based IDM needed more capability than its manual machines and older CNCs could provide. With the ability to complete parts in one setup and perform work that previously required multiple machines, the Hardinge SR-MSY multi-axis turning center was key to the shop’s competitiveness.
A new approach to management propels expansion into Swiss-type and multitasking machining work.
Just classroom training machines? No way! Visiting machine tool builder EMCO Maier in Austria, its home country, showed MMS Editor Mark Albert that the company is an important producer of advanced turn-mill machines and CNC precision lathes for both production houses and job shops.
In February 2007, I wrote a column called “Trial Machining on a Sliding Headstock Turning Center” that addressed the complexity of running a good first workpiece on a sliding headstock lathe.
Although this tooling was engineered for turn, face, profile, OD and ID groove, bore and cutoff applications, it is used in 95 percent of the company's threading functions in which large OD square threads are required.
C&R Manufacturing specializes in creating precision turned parts using CNC lathes with live tooling. Combined with the use of bar feeders, automatic gaging and robotic part handling, this enables the shop to generate intricate workpieces sans human intervention.
A job shop might have an amount of money tied up in tooling equal to a significant share of its investment in CNC machines. Here is how one shop owner thinks about tool management.
This shop uses a bar-fed turn-mill with a B-axis milling spindle and custom workholding strategies to more competitively machine components complete for low-margin medical devices.
Even when CNCs are equipped with automatic post-process gaging systems, there are always a few important adjustments that must be done manually. Don’t take operators understanding these adjustments for granted.
