Chamfering Machines

LG-500, LG-800

The DAMA LG Series is designed to meet the high demands of the optical industry on facet quality and dimensional accuracy of straight or prismatic bodies.

Based on the prism carriage principle, the LG Series incorporates a new design to easily adjust bevel irregularity. Appropriate extensions and adaptations make this model particularly suitable for machining glass or ceramic parts, and being portable, the machine can be placed wherever it is needed.

Thanks to a short set-up time and changeover possibilities within minutes, the LG Series is equally suitable for individual pieces and series production.


Features & Benefits

  • Sturdy housing assures quiet running
  • Adjustable speed of grinding spindle
  • Adjustable feed rate to suit material quality
  • Prism carriage on rollers over ball bearing guide assures NO SCRATCHING - Major advantage for previously polished surfaces!
  • Dual functionality: Pump, coolant tank, strainer, inlet & return hoses can be used as a separate unit for other purposes.
  • Tilting retaining prism provides optimal access to smoothing wheel & cooling system
  • Facet height preset by microscrew /readjustable at any time
  • Bevel size determines how fast or slow prism carriage moves over smoothing wheel
  • Coolant system keeps diamond wheel & work surface cool, & keeps diamond tool clean & free-cutting

Rounding Machines

RMD 100, RMD 200, RMD 500

Our series of RMD ROUNDING MACHINES guarantee efficient and precise production of rounds and cylinders from square or polygonal blanks.
These ergonomically-designed machines are fully automatic and operator-friendly with easily programmable controls for individual work sequences. While the diamond tool works horizontally to the rotating glass cylinder, where applicable a conical version is available by lateral adjustment of the workpieces.

RMD Rounding Machines are assembled on welded base frames assuring stability. The machines' work areas are completely protected by a tilting hood, (hinged door with window on the RMD 500). Special seals prevent the ingress of wheel swarf and splashing water in guides and drive elements. Electrical equipment and feedback control RMD 500 for rotation and feed are well protected, yet easily accessible. The machines comply with CE standards.

Spherical Generator

G-150: 6” Diameter Capacity, G-300: 12” Diameter Capacity

The G-series vertical curve generators are designed and built to meet requirements for greater accuracy in generating spherical and plano surfaces. Designed to grind blanks to 12 inches (300 mm) in diameter, the G-series incorporates years of practical shop-operations experience to decrease set up time and increase production efficiency.

Pellet Grinder

100, 250, 500, 4”, 10” 20” Capacity

These high speed grinders are used in the intermediate steps between generation and final polish to refine characteristics of generated surfaces. Our bonded-diamond lapping methods enable production of consistent, more uniform radii and stock removal while maintaining high production rates. Designed with an air-open cylinder to raise and lower the over-arm pin and apply working pressures during production cycles, these grinders produce significant savings in factory floor space and labor.

Bench Polishing & Grinding Model Makers

MM-300: 12” Capacity

Used principally in the making of test glasses, correcting lens surfaces and prism angles, salvaging lenses, beveling, and reshaping diamond pellet laps. This grinding and polishing bench provides the hand worker with a smooth, controlled, slow-speed treadledrive, as well as the convenience of motorized operation. Manual or motor driven.

Hand Roughing Bench Hand Polishing & Grinding

RGB - 300, 500 & 700, 12”, 20” & 36” Capacity

This series of hand roughing benches meets the requirements for the versatile hand grinding and polishing, tool corrections, prototype and small quantity production. Designed to grind and polish concave, convex and plano surfaces, the RGB hand series features a sturdy, quickly adjustable manual overarm for stoke length.
