Fischer Harvel LLC Machining Shapes Bulletin HPB-111 for additional information pertaining to materials physical properties machining recommendations and other technical data. The machining characteristics of different plastics vary somewhat.The recommendations given are general and may require modification to obtain the best results.The data furnished herein is provided as a courtesy and is based on past experience limited testing and other information believed to be reliable.This information may be considered as a basis for recommendation only and not as a guarantee for its accuracy suitability for particular applications or the results to be obtained there from. Materials should be machined and tested under actual use conditions to determine suitability for a particular purpose. Recommended Machining Practices Residual stresses are inherent in all extruded profiles due to the nature of the extrusion process. The amount of inherent stress will affect the products long term stability toughness and machineability. Certain machining practices regardless of the material being machined can generate excessive stress. When induced stresses caused by the effects of machining are added to the existing residual stress product failure can result. Georg Fischer Harvel LLC has addressed this phenomena by refining its extrusion processes to reduce and continually monitor internal stress levels present within extruded bar to ensure consistent machine stock. The following machining recommendations will help minimize the amount of stress being induced during the machining process. 1. Heat Generation should be kept to a minimum during all machining processes. a. Actual testing should be conducted to determine the maximum speed a particular tool can be used without generating excessive heat. b. Cutting solutions of water soapy water a suitable lubricant or cool air jet should be considered for cooling during the machining process. CAUTION Certain oils and lubricants typically used f

or machining of metallics contain stresscracking agents that are not compatible with PVC or CPVC materials. Contact the lubricant manufacturer for compatibility prior to use. 2. Turning and Boring - High-speed steel and carbide tools are typically used for most plastics. A common practice is to follow the feed and speed rates that are typically used for machining brass. Speed rates for high speed steel tools commonly vary between 250-500 ft.min. rates for carbide tools can vary from 500 to 1500 ft.min. Tools used should have less clearance and more rake than those used for steel or other metals. 3. Drilling - Carbide tipped bits are recommended for high volume production. Extra clearance at the back edges of the flutes is desirable to reduce heat generation caused by friction. Drill speeds can be as high as 12000 to 15000 Rpms with carbide tipped bits. Bit points should have an included angle of 55 to 60 for thin sections and 90 for thicker sections with a clearance angle of 15. Lubrication or an air jet should be provided for to avoid excessive heating and aid in chip removal. Commercial high speed steel drills specifically designed for use with plastics are available which have large flutes for easy chip removal. 4. Tapping and Threading - A high speed steel nitride chromium plated tap with a rake from 0 to -5 is recommended for tapping small holes. Tapping speeds usually vary from 40 to 55 ft.min. The size of the hole should allow for approx. 34 of the standard thread depth. When cutting a 60 thread such as ANSI B1.2.1 the tool used should be ground to cut on one side only and fed in at an angle of 30 by setting the compound rest at this angle. 2012 Georg Fischer Harvel LLC 300 Kuebler Road Easton PA 18040 610-252-7355 Fax 610-253-4436 Product Specifications O.D.
