FOR TOOL BLANK PREPARATION AND WEAR PARTS
PEELSERIES: PEEL & PLUNGE GRINDER
International Tool Machine’s (ITM) Universal OD Grinder was developed for grinding cylindrical or tapered parts with multiple steps or profiles. To hold the tightest tolerances the parts are clamped between high precision centers, which allow grinding along the complete part length without the necessity of reclamping. The centers can be mounted to spindles that rotate the parts with speeds up to 5,000 rpm. This arrangement eliminates the usage of driving dogs, because the taper of the centers delivers enough driving force, especially when both sides of the part are driven. However, various driving options are available if the force of the centers alone is not sufficient for certain applications.
The machine is equipped with an oversized direct driven motorspindle that enables running grinding wheels with up to 20,000 sfm. The spindle is designed to accommodate wheel flanges that hold up to two wheels, which allows combining traditional plunge grinding and oscillating with modern high performance peel grinding. With this approach it is possible to complete various parts in one clamping, which would require multiple set-ups on conventional machines.
The Peel Grinder is capable of tool grinding materials such as High Speed Steel (HSS) and Carbide. Customers prefer the advantages of producing their own blanks in high production batches with high precision accuracy. Thus, they avoid the cost of purchasing expensive blanks.
For tool loading and unloading, ITM offers a cassette loading system. Up to 300 pieces can be pre-loaded in cassettes for long periods of unattended operation.
PEEL GRINDING – High Precision OD Cylindrical Grinding
Peel grinding resembles turning. A narrow 14″ wheel is rotated at up to 30,000 sfm and manipulated along the part using two-axis interpolation to create the desired part shape. Material can be removed at .040″ per pass at 3.5 ipm in carbide and 11 ipm in HSS! New part shapes are easily programmed using menu driven software.
