Stanje: novo, Leto izdelave: 2026, obratovalne ure: 1 h, Funkcionalnost: popolnoma funkcionalen, številka stroja/vozila: 2026, We have a couple of questions for you: Why do you spend so much money every year outsourcing the sharpening of your drill bits, or frequently purchasing new solid carbide (HM/VHM) or high-speed steel (HSS) twist drills, instead of making a one-time investment in a professional drill bit grinding machine that will pay for itself in just a few years? In the long-term, you will save money, materials, and tied-up capital. You will also ease the workload for your employees and, not least, gain valuable time that you can use for other tasks! Drill bit grinding machines from BERGER are: precise – fast – simple – economical – value-retaining They help you boost productivity. These ergonomically designed, easy-to-operate, and precise drill bit grinders offer you, among other things, the following advantages: · Significant increase in tool life, thanks to an even distribution of cutting forces on both edges · Considerable reduction in feed force, due to precise and symmetrical web thinning · Improved diameter accuracy – the precise and optimized grinding produces holes that match the nominal drill diameter exactly · High positional accuracy – the sharp drill tip, with precise web thinning nearly to the center, prevents the bit from wandering at the initial contact with the workpiece, cutting instantly and accurately like an NC spotting drill · Regrinding, web thinning, and inspection – all in a single clamping operation · Achieve a perfect point geometry with web thinning in just one minute · Greatly reduced need for new drill tools, as you can now regrind and resharpen your existing bits in-house up to 40 times or more, whether they are HM/VHM or HSS · We manufacture the complete machine ourselves and use it daily in our own subcontracting production – so we know exactly what we’re talking about! · SWISS MADE quality that will serve you reliably for decades! Our three different professional drill point grinding machines are priced from EUR/CHF 3,600 to 14,950 (depending on model and configuration). Technical Data: · Point angle steplessly adjustable: 80° – 150° · Optional: point angle adjustable to 180° · Collet chuck for drill diameters: 1 – 6.5 mm · Collet chuck for drill diameters: 7 – 20 mm · Optional collet set for drill diameters: 20 – 30 mm · Cutting/lip relief angle steplessly adjustable: 0 – 40° · Web thinning device, adjustment depth steplessly adjustable · CBN double grinding wheel, fine/coarse, D 125 mm Kedpfx Aj R R R Seg Tsdr · Optional diamond grinding wheel (for carbide drills), D 125 mm · CBN grinding wheel for web thinning, D 50 mm x 4 mm · Motor power: 0.3 kW · Spindle speed: 2800 rpm · Electrical connection: 230 Volt, 50 Hz · Dimensions (L x W x H): approx. 50 x 50 x 50 cm · Weight: approx. 42 kg
