Acra Machinery, Inc. provides CNC and manual machine tools to the metal working industry along with the Acra logo signifying quality- value and service. The Acra brand is distributed world wide by Frejoth International Ltd. and in North America by Acra Machinery, Inc.
A Tilting Wheel Head For Easy Clearance Setting:
• The Wheel Head is designed so that it can tilted easily to ±15 degrees. It can also be swiveled 360 degrees on the horizontal plane. Both of these features, make it very easy to set rake and relief angles, and make for a very wide angle of grinding.
• The Spindle assembly is designed so that the spindle shaft is supported by two pairs of angular ball bearings, one pair at each end of the spindle support. The bearings are properly pre-loaded by tightening the nuts. Incorporated in the design also is compensation for expansion by heat. The grinding wheel spindle is grease lubricated for life and no additional lubrication is required.
Universal Work Head:
• The Work Head is positioned on the table as desired by the operator and can be swiveled accurately at any angle both horizontally and vertically. It means it can be swiveled optionally. Set to obtain the most suitable angle for a specific grinding job. It has a taper hole in each end of the spindle, one M. T. No. 5 (or B & S No. 12), the other ASA No. 50.
Accurate, Versatile Table:
• Table Swivels 120 DEGREES: The table is equipped with a graduated scale and swivels ±60 degrees.
• This ±60 degrees swiveling combined with the 360 degrees swiveling of the wheel head extends M-40 versatility when grinding large(long) cutters and tools.
Anti-Friction Slide Way Bearings Used:
• For precise smooth table slide, the table ways have been hardened and ground and anti-friction slide way bearings are used. The table is controlled by the winding motion of cable on to a take up reel, which insures back-lash free operation. Because of this construction of table, operation is light and smooth. So that it does not fatigue the operator.
Finger Tip Control:
• It is necessary that the table be easily controlled from fine to rapid feed range to handle various grinding requirements. The M-40 has table feed knobs on the right- and left-hand side of the table. Also, there is a crank handle on the right-hand side for fine table control. The table feed mechanisms are so designed to be controllable by fingertip action that it permits integral response of grinding conditions to operator hand.
Tailstock:
• The Tailstock can be easily positioned at any place on the table. It is combined with the Work Head or other Tailstock to hold the work piece. Design is such that the Tailstock can be aliened easily and positively by pushing both to one side of the table slot by thumb screws. The right Tailstock has a retractable center for easy work piece mounting and dismounting.
Centralized Lubrication:
• For cutter grinding operation, precise tool grinder’s movement is of primary importance, and it must be at all times maintained. This means a complete lubrication system is necessary. The M-40 is equipped with the centralized system which lubricates all the required points, shown at the right. This system is not only saving you time for daily lubrication, but also keeps the machine in its best condition to extend its life.
