These internal grinding machines offer excellent versatility, high levels of quality, batch size flexibility, easy workpiece presetting, and effective complex component processing.
Internal grinding is an abrasive form of machining that uses a rough grinding wheel to cut through a variety of hard materials. This machine is a great option for grinding the internal diameter of a workpiece.
All of our Internal Grinders have heavy aged cast iron construction precisely machined and scraped by hand. Expect many years of problem-free operations and high accuracy due to the Hydro-Static lubrication system on the table.
With excellent versatility and high-quality standards, the IGR 250 and 600 provide small batch production of workpieces in manual or semi-automatic modes. You can even craft a single workpiece.
On machine-setup, the workpiece presetting is configured and then you're set to produce. Produce quickly and precisely, even when dealing with complex components, and take advantage of more sophisticated functions with machine upgrades.
If your production is seeking high precision grinding, the CNC IGU 400 is the machine you're looking for. With up to 4 grinding spindles on the rotating turret, this CNC motor-controlled machine and software interpolation 2-axis allow various ray adjustments, customized to your production requirements. Also, tap into roller linear guides (for maximum rigidity), a granite base (low thermal expansion), an incremental linear encoder (dampens vibrations), and axis movement via the high precision re-circulating ball screw.
