COFA‑X Cross‑Bore Deburring Tool

Ball Valves, Crankshafts, Engine Cylinder Blocks

HEULE COFA-X is a high-efficiency deburring tool engineered for complex working conditions such as cross-holes, deep holes and blind holes. Crafted with Swiss precision technology, it achieves precise removal of burrs on both inner and outer sides of cross-holes and chamfering in a single operation, eliminating the need for secondary processes. Its adaptive floating structure automatically compensates for hole position deviations, compatible with various difficult-to-machine materials and complex hole diameters, significantly boosting processing efficiency and consistency. Compared with traditional manual work, sandblasting and other methods, COFA-X improves deburring efficiency by over 80%, ensuring stable hole accuracy. It is widely used in automotive, hydraulic, aerospace and other industries, helping customers reduce costs, increase efficiency and achieve high-quality automated machining.

BSF Back Spotfacing Tool

Aero-engine casings, landing gear structural components, automotive engine cylinder blocks, transmission valve bodies

HEULE BSF is a high-performance back spotfacing tool developed by HEULE Precision Tools (Switzerland). The maximum back spotfacing diameter reaches 2.3 times the through-hole diameter, and the carbide blades deliver a service life above the industry average. It is reliable, cost-effective, and user-friendly. The BSF enables machining on the backside of holes without flipping the workpiece, and its special blade window design ensures process reliability. The tool is ready for immediate use without pre-setting, making it extremely easy to operate. It can be flexibly applied on various machine tools, and its modular system supports multiple actuation methods: coolant, air, and manual.

Shrink Fit Tool Holder

Aerospace superalloy blades, precision semiconductor chamber components, high-end molds, EV motor housings

German-engineered induction heating combined with in-house dynamic balancing measurement ensures superior concentricity and ultra-low vibration at speeds ≥25,000 rpm. Extends tool life by >30%, achieves surface finish ≤Ra0.1μm, eliminates chatter in high-speed machining. With continuous R&D investment, the next-generation shrink fit holder delivers improved clamping force and thermal cycle life – ideal for stable, high-efficiency finishing.

Shrink Fit Machine

Fast and uniform heating & cooling for all shrink fit tool holders, ideal for high-precision machining in aerospace, mold & die, and automotive parts production.

Intelligent shrinking technology from a single source! SCHÜSSLER offers you a complete solution for all types of shrink fit chucks. The heart of the inductive shrink fit technology is the patented induction coil. It is equipped with two separate windings, this allows them to be controlled independently of each other, resulting in an optimized heating temperature and heat distribution at the clamping area of the chuck leading to shorter cycle times and a longer tool life of your chucks.
