he high-performance S32cnc external cylindrical grinder is a new addition to the Studer line of United Grinding Technologies Inc.The S32cnc is described as having “chameleon-like” properties in that it addresses a diversity of applications and can be tailored to match today’s fluctuating production demands.
This is possible due to a number of unique capabilities: an x-axis which may be arranged for angular infeeding (wheel at 30º) or infeed grinding on the left or right (wheel at 0º). This permits the machine to process very basic, straightforward workpieces or highly complex pieces. In a standard configuration, with the grinding wheel on the right and a between-centers distance of 400 mm, the S32cnc is well suited for grinding small- to average-size cylindrical workpieces. An optional C-axis permits ultraprecise form grinding routines for tooling and thread grinding. Hydrostatic guideways on the x-axis permit extremely rapid traverse rates with minimal axis lag.
Arranged for high-speed grinding (with cutting speeds in excess of 125 m/sec) the S32cnc takes on difficult-to-machine materials, such as zirconium ceramics or tungsten carbide.
Hardinge Demonstrates Economical
VDI Tool Presetter at IMTS 2002 Show
Hardinge Inc. demonstrated a manual VDI tool presetterat the recent IMTS in Chicago. The system can reduce machine downtime during job set-up on horizontal and vertical turning lathes. Machine operators can measure tool position height and length outside of a machine during cycling, thereby minimizing downtime during set-up.
This manual unit is presented as an economical solution to VDI tool presetting at every cell. The small (12 x 18 in.) footprint makes this a portable unit that could be shared by operators or individual units for every cell.
The system includes a 12-in. manual height gage, centerline block, 12 x 18–in. granite surface plate, and a choice of a VDI 30 or VDI 40 toolholder block. Individual components are also available for use with existing equipment.
