1 DEEP HOLE DRILLING SYSTEMS SOLID CARBIDE TOOLS Grinding fixtures ZS/ PS for regrinding single flute gundrills dia. 0.5 mm

Grinding fixture ZS Grinding fixtures PS The botek grinding fixture ZS is designed for low volume production re-sharpening of single flute gundrills.

The gundrill is inserted in the clamping unit and a vee-shaped jaw holds the gundrill securely in the flute.

2 Grinding fixture ZS Grinding fixtures PS The botek grinding fixture ZS is designed for low volume production re-sharpening of single flute gundrills. The fixture may be installed on a botek grinding machine MS-01, or a standard ol grinding machine. The desired angles are set on the grinding fixture using graduated scales. The gundrill is inserted in the clamping unit and a vee-shaped jaw holds the gundrill securely in the flute. The botek grinding fixture PS was developed for re-sharpening single flute gundrills within a diameter range mm. The fixture may be installed on a botek grinding machine MS-01 or a standard ol grinding machine. By changing the grinding stations, our standard nose grinds SA-0009, SA-0002 and SA-0227 can be produced. The angles of the cutting edges are fixed, depending on which grinding stations are chosen. Single flute gundrills are clamped in a ol holder for re-sharpening. Each ol holder is suitable for one gundrill driver diameter of 10, 12 or 12.7 mm. The ol holder is inserted in each grinding station and pressed against the adjustable sp and passed across a rotating diamond wheel. The relief angles are achieved by moving the grinding station a second position. Gundrills are clamped in the ol holder using a pre-setting fixture with microscope. A different ol holder bushing may be ordered for each gundrill diameter. Tool holders are available in specific gundrill diameter ranges and driver types. Please refer the following page for further details. Grinding Fixture ZS When choosing a grinding fixture, please consider the required flute lengths and gundrill diameter range be sharpened.

4 Cup wheel Standard nose grinds for botek single flute drills Cup wheel For re-sharpening single flute gundrills within a diameter range 0,5 2,0 mm a cup wheel is most suitable. The gait of the wheel is chosen keep an excellent grinding quality and sufficient sck removal without overheating the ol. Order No: Standard nose grinds for botek single flute drills The nose grind geometry affects the following: chip formation, drilling lerance, centerline deviation (drift) and ol life. Over the years, botek has successfully tested a number of different nose grinds for drilling various materials. botek s experience has formed the foundation for the development of our standard nose grind geometries. This meets the requirements of most drilling applications. Deep-hole drilling of especially long chipping materials and difficult machine materials usually call for special nose grind geometries, and in some cases, made order chip breakers. Regrinding instructions can be provided case case. If there is no other information given, botek single flute drills will be reground as per nose grind SA-0001, SA-0002, SA-0003 and SA-0009 as shown below. Double grinding wheel The double grinding wheel is ideal for re-sharpening single flute gundrills up 45 mm diameter. The coarse grit of the outer wheel is for roughing the ol with high sck removal and minimum heating of the ol. The fine grit of the inner grinding wheel provides optimum surface finish with light sck removal. Order No: SA-0009 (No. 0001/1) Drill-Ø mm SA-0001 (No. 0001) Drill-Ø mm 6 Remark: We recommend re-sharpening gundrill diameters greater than 32 mm on larger machines.
