Affordable, Versatile, In-House Regrinding Operations Aimed for Mold Shops

Walter Maschinenbau GmbH’s latest addition to its comprehensive machine lineup is the compact Helitronic G 200 tool grinding machine, a key solution for affordable, versatile in-house regrinding operations in a mold shop. In a floor space of less than 24.8 square feet, the Helitronic G 200 offers grinding and re-sharpening of rotationally symmetrical cutting tools ranging from 1 to 125 mm (0.039" to 4.92") in diameter with a grinding wheel up to 150mm (5.91"), ideal for moldmakers, who typically utilize a high volume and mix of cutting tools. The Helitronic G 200 can reportedly accommodate a maximum tool length of 235 mm (9.25") and a tool weight of up to 12 kg (26.45 lbs).

The ergonomic design integrates a swiveling multifunction touch panel with a 21.5" monitor, facilitating easy operation and accessibility to the working area. A low-vibration solid mineral cast bed and C-frame construction offers high damping capabilities and thermal stability, which Walter says results in maximum grinding precision. According to Walter, the linear X, Y and Z axes are built to high-quality standard, and the rotating A and C axes are equipped with torque motors to provide a long lifetime with minimum service effort.

The Helitronic G 200 uses the Helitronic Tool Studio grinding software from Walter, which is said to simplify programming, simulation and makes operating the machine a breeze, all important factors in ensuring more productivity for a mold shop.

The Top Loader loading system is directly integrated into the work envelope of the machine for easy access and therefore requires no additional floor space. Suitable for tools from 3 mm to 16 mm (0.118" to 0.63") in diameter, the maximum tool capacity of the loading system up 500 tools for tools with a 3 mm (0.118") diameter. The Top Loader uses Walter-standard robot pallets and automated electrical teaching.
