STP618 Series Surface Grinders

Machine Information

Affordable and easy to operate, the Supertec 618 Series of surface grinders are design and built for accuracy, durability and smooth performance. Available in 5 different models, these machines offer many features and solutions to increase your productivity

STP-618M: Hand Feed Surface Grinder
STP-1A618: Hydraulic Table Travel Grinder
STP-2A618: Hydraulic Table and Cross Feed Grinder
STP-618CII: Hydraulic Table, Cross and Down Feed Grinder
STP-618CXII: Hydraulic Table, Cross and Down Feed Grinder, and Slicer.

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.

Powerful 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)
