C1020L2 Cylindrical Grinding Machines

Built with American Pride
A fine example of American craftsmanship, our C1020L2 and Scepter Cylindrical Grinders are built 100% in the U.S.A. and designed to provide an uncomplicated grinding system at an economical price. Both models feature annealed cast-iron construction throughout the entire machine, including the base, wheelhead, saddle and table. This quality construction provides the C1020 & Scepter with a lifetime of stability and accuracy. The special saddle infeed construction and table features a pre-loaded anti-friction way system, for extreme accuracy of movement.

C1020L2
The C1020L2 features servo-driven movement for easy operation. The Leematic 2000 control is standard on this model and provides microprocessor-based operation of table traverse and wheel infeed travel. The Leematic 2000 control is menu-driven for simple operation. Both axes are ballscrew driven, via servo motors with full closed-loop feedback for accuracy. Built-in programs include TRAVERSE, STEP, SHOULDER and PLUNGE grinding cycles, in addition to full in-cycle WHEEL DRESSING with fully automatic wheel dress compensation.
Menu-prompts allow the operator to "fill in the blank" with acceptable parameters. Up to 23 programs can be stored and recalled.

Within a single program, each routine can be repeated up to 999 times, and the entire cycle of all routines can also be repeated up to 999 times for complex part grinding with only one setup. Additional features of the Leematic 2000 control include totally integrated circuitry, self-diagnostics, a back-lit LCD screen, and soft touch keypad with a contaminant-impervious membrane. Rapid traverse, rough and fine increments, sparkout passes, and compensation for lead screw error and backlash are also included.
Optional internal grinding applications include straight I.D. and shoulder and step cycles. Optional software programs, including taper correction/grinding and angle dressing, are also available. Radius grinding/dressing requires the use of the CNC control. Push-button cylindrical grinding made simple Both models feature a user-friendly control that requires a minimum of operator training before operation. The Leematic 2000 control features menu-prompting to "walk" you through the program parameters. Both models use servo drives for accurate, closed-loop positioning of both axes.

Customized to your application
The multifunctional grinders are capable of both O.D. and optional I.D. grinding. Plunge, traverse, shoulder, taper and radius grinding applications, or combinations of cycles are available (some cycles require optional software or use of the CNC model). Cycles for dressing and wheel form generation are also available. Workpieces can be held by chucking or between centers, which makes the machine ideal for tool room or production environments. Multi-diameter grinding capabilities reduce the need for multiple set-ups and improves overall productivity. Automatic infeed allows presetting for rapid approach, feedrates, change points and final sparkout. These features result in improved speed, accuracy and efficiency of the grinding process.
