Product Information CHD 270, CHF 270 and Automation Automated comprehensive machining of uncoated carbide circular saw blades

VOLLMER‘s automation concept: Greater flexibility, cost-efficiency, and precision. With this machining concept, VOLLMER sets the standard for the highly efficient, automated grinding of carbide-tipped circular saw blades in production and s ­ ervicing. VOLLMER‘s Automation Concept represents a modular system consisting of standalone CNC-controlled machining units designed to sharpen tooth g ­ eometries on the tooth top, face and sides, connected with an intelligent h ­ andling system. When combined, these units form a highly flexible work-flow set-up that can be customized to meet your...

CHD 270 – all-in-one tooth top and face machining A grinding machine with eight CNC-controlled axes and a measuring device, designed for the automated machining of carbide-tipped circular saw blades of various diameters and tooth top and face geometries. CHF 270 – all-in-one tooth side machining A grinding machine with seven CNC-controlled axes and a measuring device for two-side peripheral grinding. Designed for the automated machining of carbide-tipped circular saw blades of various diameters and tooth side geometries. Technical Data Intelligent loading system A handling system with four...

CHD 270 – all-in-one tooth top and face machining in a single pass. B A new step ahead in innovating a superior machine concept to ensure the highest grinding precision for uncoated carbide circular saw blades. Fully CNC controlled (with 8 CNC axes) including the feed, hook and clearance angle adjustment and automated measuring device. The machine design brings you high stability, requires little space and allows easy operation. The CHD 270 grinding s ­ ystem is fully self-enclosed and robust, built on a central block (mono-block design). This ensures the highest precision and smooth...

Highest flexibility for all tooth shapes. Designed for universal applications Its eight CNC-controlled axes combined with the VOLLMER PMC control enable the machine to be used for universal applications. A wide variety of different grinding programs are already pre-programmed, and the main program can be used anytime to add special tooth geometries. Examples of tooth shapes: Tooth face Vektor-Daten anfordern!!! Tooth face machining Vektor-Daten anfordern!!! Examples of tooth shapes: Tooth top Every tooth geometry, including various chamfer and bevel grinding angles, is ground in only a...

Precise and fast – tooth geometry grinding for the metal-working industry. The CHD 270 is designed to meet the ultimate precision requirements of saw blades used to cut metal in the metal industry. The machine is built to be robust, offers CNC-controlled axes, variable control options and convenient operation. Even complex tooth geometries can be ground completely in a single clamping, including chip breaker grooves, chamfers on the roughing and finishing teeth, Braunschweig tooth or chip guide notch. Hook angle of up to –35° and maximum bevel grinding angle of up to 60° guarantee the...

Intelligent control, easy and reliable operation. Product benefits: The feed pawl detects any missing teeth, thus preventing the grinding wheel from breaking. Saw blades with newly replaced teeth can also be machined in a single clamping. With the laterally mounted feed pawl and the accompanying saw blade holder, it is possible to machine cutting tool segments easily in a manual operation mode. Hollow face grinding. Machining the V-groove on the tooth top. The measuring probe integrated in the machine as a standard component measures all relevant parameters such as cutting width, blade...

Automated tooth side grinding on the CHF 270. Another step forward in developing the sophisticated machine concept to ensure ultimate precision in grinding carbide-tipped circular saw blades. Fully CNC controlled (with seven CNC axes) to ensure a ­ ll-in-one machining of tooth sides. A machine concept designed to meet the highest standard in grinding the tooth sides of carbide-tipped circular saw blades. With the CHF 270, you get a machining center with excellent features and qualities: either as a stand-alone unit or in combination with automatic loaders for saw blade production. Its seven...

All-in-one machining of all types of tooth shapes. Its seven CNC-controlled axes combined with the VOLLMER PMC control enable the machine to be used for universal applications. A wide variety of different grinding programs are already pre-programmed, and the main program can be used anytime to add special tooth geometries. All machining operations are performed in the highest quality under precise path control. VOLLMER‘s operation program for multipleface and rough framing forming can be used to program various faces, angles and oscillation machining operations on single or multiple teeth....

Technology for flexible machining. Product benefits: Each saw blade – whatever its d ­ iameter – is positioned automatically as it moves into the grinding position. The measuring probe then d ­ etermines the entire tooth g ­ eometry: hook angle, radial and tangential clearance angles, cutting width, blade thickness, lateral carbide projection and carbide length. It is this high degree of precision that ensures the accuracy of the subsequent grinding results. With the laterally mounted feed pawl and the a ­ ccompanying saw blade holder, it is possible to machine cutting tool segments easily...

Simple and easy operation. Input mask for tooth measuring. Input mask for tooth geometry. TechnICAL DatA VOLLMER‘s control technology makes it exceptionally simple and easy to operate this machine. Grinding programs, including special programs for convex tooth sides, have a ­ lready been pre-programmed in the factory and can be launched and canceled using menus on the control panel. A simple system of prompts, supported by on-screen graphics on the LCD color display, guides the operator through the program, giving him among other things important i ­nstructions how to quickly eliminate...
