"List of suitable tools for grinding" common sense of tool grinding
drill bit
Applicable scenarios:
Mold curved surface, aerospace complex structural parts processing
drill bit
Applicable scenarios:
Mold curved surface, aerospace complex structural parts processing
Technical Highlights:
(1). Do not change the diameter: only repair the R angle profile (accuracy ± 0.005mm) to avoid reprogramming.
(2). Side edge taboo: It is forbidden to directly trim the side edge, otherwise the processing parameters need to be adjusted.
(3) .3D scanning the original tool profile → 5-axis grinder repair R angle → edge passivation treatment (anti-chipping edge)
reamer
Applicable scenarios:
Heavy duty threading (e.g. valve body, flange)
reamer
Applicable scenarios:
Heavy duty threading (e.g. valve body, flange)
Technical Highlights:
(1). Priority is given to grinding large-diameter taps (M12 and above): more economical.
(2). Tooth chipping limit: more than 3 threaded teeth in a row need to be scrapped.
(3). Laser cladding repair tooth shape → 2. Cryogenic treatment (improves toughness)
milling cutter
Applicable scenarios:
Batch hole processing (e.g. automotive parts, pump and valve workpieces)
milling cutter
Applicable scenarios:
Batch hole processing (e.g. automotive parts, pump and valve workpieces)
Technical Highlights:
(1). Pre-machining/general precision holes: can be re-sharpened 15-20 times (realized by re-grinding the main cutting edge)
(2). High-precision holes (IT8 level or above): it is recommended to repair and grind no more than 5 times (need to be repaired with coating)
Threaded cutters
Applicable scenarios:
Precision hole finishing (IT level 7 or higher)
Threaded cutters
Applicable scenarios:
Precision hole finishing (IT level 7 or higher)
Technical Highlights:
(1). Number of grinding: 2-5 times (depending on the initial wear)
(2). Diameter detection: direct scrapping with an excess of 0.02mm or more.
(3). Calibration of the guide part: straightness ≤ 0.01mm.
(4). Edge repair: retain the original geometric angle and do not coat to ensure dimensional stability.
