Sliding Headstock Type CNC Automatic Lathe Switch between guide bushing and non-guide bushing type
Acclaimed for its excellent cost to performance ratio, the A20 has The performance of the machine has been improved too. The high evolved as a 5-axis machine for ø20 mm applications with the ad- speed 10,000 rpm spindle enables optimized machining operations vantage that it can be used with or without a guide bushing. Use on smaller diameter bar material. The machining length per chucking as a regular guide bushing automatic lathe when machining long, is now extended to 200 mm enabling the number of re-chuckings slender workpieces or without a guide bushing for shorter parts and therefore cycle times to be reduced when machining long with minimal bar end remnants. The guide bushing can be quickly workpieces. As an option, bar material of up to ø25 mm can also and easily mounted and removed. be machined extending the range of workpieces.
