The integrated coolant pump is essential for HM tools that quickly overheat during sharpening without cooling. At 270 kg and three-phase 400V, it is a stationary workshop machine for workshops with high consumption of various tools.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Bernardo UGM 300 for\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eProfile\u003c\/th\u003e\n\u003cth\u003eCompatibility\u003c\/th\u003e\n\u003cth\u003eReason\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHobbyist\u003c\/td\u003e\n\u003ctd\u003eNot suitable\u003c\/td\u003e\n\u003ctd\u003eProfessional machine weighing 270 kg with three-phase 400V.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMechanical workshop \/ tool service\u003c\/td\u003e\n\u003ctd\u003eIdeal\u003c\/td\u003e\n\u003ctd\u003eUniversal sharpening of milling cutters, circular saw blades, and special tools in a single machine with precise indexing head and integrated coolant.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndustrial production\u003c\/td\u003e\n\u003ctd\u003eAdequate\u003c\/td\u003e\n\u003ctd\u003eFor high volumes of identical tools, consider specialized automatic CNC grinders.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e workshops without three-phase 400V; hobby use; those who sharpen only one type of tool (dedicated DG, SBS, HMS grinders are more economical and simpler).\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax. tool diameter\u003c\/td\u003e\n\u003ctd\u003eØ 380 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax. grinding length\u003c\/td\u003e\n\u003ctd\u003e300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircular saw blades (range)\u003c\/td\u003e\n\u003ctd\u003eØ 90 – 630 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndexing head\u003c\/td\u003e\n\u003ctd\u003e24 positions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiamond grinding wheel (Ø × thk. \/ bore)\u003c\/td\u003e\n\u003ctd\u003e125 × 10 \/ 8 × 32 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpindle head height adjustment\u003c\/td\u003e\n\u003ctd\u003e225 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRadial relief angle\u003c\/td\u003e\n\u003ctd\u003e+50° … −50°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpindle head tilt\u003c\/td\u003e\n\u003ctd\u003e50° left \/ 50° right\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSide relief angle\u003c\/td\u003e\n\u003ctd\u003e−20° … +20°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLongitudinal table travel\u003c\/td\u003e\n\u003ctd\u003e300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCross table travel\u003c\/td\u003e\n\u003ctd\u003e130 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHandwheel reading\u003c\/td\u003e\n\u003ctd\u003e0.05 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrinding wheel spindle speed\u003c\/td\u003e\n\u003ctd\u003e3,500 rpm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrinding wheel motor power\u003c\/td\u003e\n\u003ctd\u003e370 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoolant pump power\u003c\/td\u003e\n\u003ctd\u003e40 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e400V – three-phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (L × W × H)\u003c\/td\u003e\n\u003ctd\u003e1,050 × 830 × 1,450 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eapprox. 270 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompliance and safety\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMarking\u003c\/td\u003e\n\u003ctd\u003eCE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDirective\u003c\/td\u003e\n\u003ctd\u003eMachinery 2006\/42\/CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eLogistics\u003c\/h3\u003e\u003cp\u003eBernardo shipping: 5–9 working days (7 days for Southern Italy).

The 24-position indexing head ensures precise positioning of each tooth for all multi-point tools.

The 24 positions cover tools with 2, 3, 4, 6, 8, 12, and 24 teeth (any divisor of 24). For tools with a different number of teeth (e.g., 5, 7, 9), an additional indexing head is required.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the coolant pump essential for HM tools?\u003c\/summary\u003e\n\u003cp\u003eYes. Tungsten carbide (HM) tools are sensitive to heat during sharpening: insufficient cooling causes micro-cracks in the carbide that drastically reduce tool life.
