STP618

Stringent Quality Control to Supertec Specifications:

• Work table flatness: 0.00012″
• Parallelism of longitudinal movement: 0.0001″/18″
• Parallelism of cross movement: 0.000080″/6″
• Run-out of wheel taper: 0.000060″

Precision Cartridge Spindle for High Accuracy
High rigidity spindle with four preloaded class 7(P4) bearings and run-out of spindle taper less than 0.000060″ T.I.R. provides quiet, vibration free operation for better workpiece accuracy and surface finish. The cartridge type spindle is interchangeable for easy maintenance and field replacement. Spindle bearings are grease sealed for life.

Poweful 3HP Low Vibration Spindle Motor
3 HP V3 grade spindle motor assembly is dynamically balanced for low vibration and powerful
output to achieve precision work standards and better grinding capability.

Smooth Ball Ways
The ball way table travels on hardened and ground guideways to ensure smooth, easy movement of table for better quality surface finish and longer way life.

Hand Scraped Double V Base and Saddle Ways
Cross way surfaces are hand scraped and Turcite coated for absolute flatness and high wear resistance. Thus, It assures a smoother saddle movement for higher accuracy and longer life.

Rugged Construction
All castings are heat tempered and stress relieved twice during the manufacturing process to assure stability of the machine structure and resist deflection under load.
Massive one-piece cast column is heavily ribbed for rigidity. Hardened & ground tool steel column ways with cast spindle slide is precision fit for smooth gravity downfeed.

Auto Lubrication System w/Waste Reservoir
The lubrication system continuously floods the saddle, the column ways, and the leadscrews with non-recirculated filtered lube oil for better performance and less maintenance.

Table Reversal Mechanism
The table reversal is hydraulically powered and actuated by non-contact proximity switches. Table speed and stroke are infinitely variable and can be easily adjusted for ease of operation and higher grinding efficiency. (except 618M)

0.000050″ Micro Downfeed and Crossfeed

Optional down feed and cross feed micrometer attachments are calibrated to 0.000050″. Finer
adjustment by engaging worm gear allows higher grinding tolerance with ease. (standard on CII/CXII)

Mitsubishi PLC control uses a menu-driven LCD touch screen technology for simple operation. (CII and CXII Models only)
