Q:How do you choose the tolerance of reaming when reaming?
Suggest you see. The worker's Manual of cutting! The cutter head is on.
Q:Hole diameter requirements 30, 0-4 wire, what specifications of the reamer?
Hello. It's fine to use a high precision reamer. 980312522QQ Germany BECK shell reamer can meet this requirement. Our reamer is the size after reaming.
Q:The reamer H7 and H8 are of high accuracy
The H7 of the reamer is higher than the reamer H8, and the accuracy of the reamer is D4, H7, H8, H9 and so on;Their difference: the deviation is different; the structure of the reamer is mostly composed of the work part and the handle part. The main part of the work is cutting and calibration functions, the calibration Department has inverted taper diameter. The shank is used for clamping by the clamp and has a straight handle and a taper handle.A rotary tool with one or more cutter teeth used to remove thin metal on the surface of a machined hole; a rotary finishing tool having a straight or spiral blade; used for reaming or trimming. A rotary finishing tool having a straight edge or a spiral edge; used for broaching or trimming holes. The cutting accuracy is usually higher than that of the drill because of the small amount of cutting. Can be operated manually or installed on a drilling machine.
Q:Please enlighten brother snow reamer 150125110 motorcycle valve is not universal and how the hinge valve
Motorcycle valve reamer is a set of the above several cars can be common.Reaming the valve is the best way to find a local repair car or motorcycle master, which is not clear here.Generally use 75 degrees, then 15 degrees and 45 degrees of reamer, and finally the effect after reaming, and then use several tools to trim. Use 45 degrees to the right contact width of reamer, reamer can take 15 degrees contact hinge low 75 degree knife to contact surface to improve the contact surface, preferably 1 mm or so, if it is too wide for 15 degrees and 75 degrees of cutting narrow. After reaming, grind the valve and check the seal.
Q:What's the difference between a bore cutter and a reamer?
In general, a reamer is fixed size tool, cutter is adjustable size tool.
Q:Use and do not use the threaded hole reamer reamer, what do you mean, how to choose the aperture
Thread hole processing technology is generally drilling, and then tapping. Refers to the bottom hole diameter. For example, M10*1.5 ordinary coarse thread screw, the bottom diameter is Phi 8.37 internal thread processing, to the processing of a hole, the hole diameter than the nominal diameter of the small number of threads, the hole is threaded hole. The common thread bottom hole diameter can search the Internet access to "form" the threaded hole diameter, different hole size tolerance zone is slightly different.The empirical formula: ordinary screw diameter =d- (1 ~ 1.1) P type, D - P - pitch diameter of screw. If the thread M10, pitch 1.5mm, calculated by the empirical formula, the bottom diameter of =10- (1 ~ 1.1) * 1.5=8.35 ~ 8.5, 8.4 bits to drill on the line. Processing of general internal thread diameter underport metric - thread path is what. Refers to the bottom hole diameter
Q:Difference between milling cutter and reamer
The reamer has a certain taper, but the pattern of the reamer is vertical ~ the knife end is relatively flat,The pattern of the milling cutter is spiral, with a sharp blade in the cross section
Q:When reaming the piston pin hole and connecting rod copper sleeve, how much is the pin allowance?
Repair the car when the hinged piston pin hole and the connecting rod copper sleeve hole is generally used manual reaming holes, more than the amount of not more than 0.2mm, margin will put the heating hole reaming Reaming with best ream, plant oil, reaming allowance of not less than 0.05mm, the low margin is not hinge hole light. The roughness is not standard, affect the service life, the conditions can also toggle, low speed, feed to slow, do not reverse or scrape pores, also use vegetable oil to stop hinge, hinge reamer can lift it up and out. Reaming allowance 0.05mm-0.2mm.
Q:What are the causes of internal bore runout in lathe reaming?
Workpiece runout error is too large
Q:In the lathe, with a floating reamer machining material for cast iron, diameter of 55mm hole, leaving margin 0.1mm, lathe speed is appropriate!!
Reaming is actually the lower the speed, the better, but to balance with efficiency. So, according to the actual choice of 30-120
