Making A Mirror Grinding Tool By Allen Malsburry The average person would never think, I can make my own telescope. Most amateur astronomers believe, I can buy a better telescope than I can build. Neither is actually correct. For many decades now, amateur astronomers have been building their own telescopes. ...
Mirror-o-Matic was designed to be a very low cost astronomical mirror grinding, polishing and figuring machine. Its attributes are 1. It can be built for somewhere between $200 and $400. 2. It is constructed of hardware store items and it needs no machined parts. 3. It is constructed primarily of 3/4 inch plywood and has few close tolerances. 4.
Grinding Motion Move mirror back and forth over tool grinding compound After number of strokes rotate mirror, tool in opposite direction Change position of stroke alternatively Eventually move fully around the mirror Grit removes material from both But tool edges wear down, while mirror center carved out
Mirror -o-Matic 4 U se of existing parts. In this conversion manual, I have deleted the pages for the entire powerhead a s-sembly, the eccentric drive, the eccentric push rod and the swivel assembly. These parts are almost identical to the smaller or iginal Mirror -o-Matic parts and will work as in the bigger machine.

Grinding Machine for Large Telescope Mirrors I designed and built a grinding machine for mirrors up to 42 inches 1.1m in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work.
Mirror-O-Matic grinding machine. When I decided in 2009 after a ten-year break to get into mirror making again, it quickly became clear to me that I would need to construct machine, as hand grinding big mirrors is not something very beneficial for the hands of a musician.
machine, or polishing machine. During grinding high speeds are required, whereas lapping and polishing applications are generally completed at low speeds. The Model 920 also incorporates workstations, which allow for the use of precise Lapping and Polishing Fixtures. Each workstation has its own speed control, allowing the user to precisely
Grinding On the picture below the machine is fine grinding an 8 inch mirror with an 71% tool (143 mm diameter) and 9 micron aluminium oxyde. The bent lines on the mirror are the effect of the tool turning - with respect to the mirror - faster at the central part of the mirror as compared to the edge zones.
Aug 19, 2019 Gordon Waite is probably one of the better mirror makers using this machine and have incorporated some of his ideas into my plan. I like the fixed-post plan vs others with eccentric drives, because it gets the heavy grinding done in an automated manner, but still give you the chance to hand-figure.
Other roles are played by the grinding fluid including keeping the machine cool, keeping the body of the workpiece cool and flushing away the grinding debris. This latter role is particularly important in high removal rate grinding and in mirror finish grinding.
An apparatus and a method for mirror surface grinding which enables high quality, stable ELID grinding and a grinding wheel for electrolytic dressing. The apparatus comprises a grinding wheel 3 having a contact surface 2 for contacting a workpiece 1, an electrode 4 facing the surface 2, nozzles 5 for supplying conductive fluid between the grinding wheel 3 and the electrode 4,
An automatic grinding and polishing machine is shown in Fig. 4.1. Automatic grinding methodsteps are 1. Symmetrically load three to six mounted specimens into the specimen holder of an automatic grinding-polishing machine, with the at sur-face of the ceramic section downward. Most manufacturers provide a
Grinding Ex. 1-1 You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
Aug 16, 2015 This study proposes a high-precision compensation system using an on-machine noncontact measuring system to improve the manufacturing accuracy and efficiency of large-diameter aspheric mirrors by reducing profile errors arising from tool setting errors and machine positioning errors. By measuring a standard hemisphere, the assembly tilt angle of the

May 18, 2019 Grinding force has a direct influence on grinding wheel wear, grinding temperature, the surface quality of the work piece and the design of machine tool component. Also, the cutting force is proportional to the specific energy in grinding and this influences the performance and surface integrity of the work piece.
The I.A.U. named asteroid 17823 Bartels discovered 1998 by J.M.Roe in recognition for my contributions to amateur astronomy. Making is the Key to Knowing. A telescope mirror is arguably the most accurate surface made by human or machine. Amazingly you can grind a mirror by hand and make a telescope with simple hand tools.
Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 P180-P280 is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
In the mold manufacturing process, smooth processing and mirror processing after shape processing are called surface grinding and polishing of parts, which is an important process to improve the quality of the mold. Mastering a reasonable polishing method can improve mold quality and service life, thereby improving product quality.
These machines are frequently equipped with coolant attachments to ensure cool cutting and to help wash abraded particles from the belt or disc. Care should be taken to prevent overheating of the specimen during the rough grinding stage. Abrasive belts or discs for wet grinding usually employ Silicon Carbide as the cutting media.

(Nanogrinder, Grinding Machines Nuernberg, Inc., Erlangen, Germany). During grinding, deionized (purified) water is being used to cool the grinding wheel and the wafer surface. Surface grinding can be used for grinding wire-sawn wafers, to replace or partially replace lapping. It can
Oct 31, 2008 edging machine that can grind the outer diameter and put bevels on both sides in one run. Although less common, bevels can also be added after centration, either using a stone grinding wheel or convex or concave bevel tools.
Hello viewers, so today we are going to study the Definition, Working, Types, and Operations of the grinding machine.And at the end of the article, I will give you a PDF downloadable link so that you can download the PDF of the grinding machine as well.. In the manufacturing process grinding operation is also an important operation to make a finished product, so lets start the
Much is also unchanged - mirror grinding techniques are very similar to those written up by Porter and Ingalls in the 20s and 30s. Many amateur astronomers still choose to fabricate their own instruments, for the pride of accomplishment, the gaining of
LPC 300 Mirror Big sister of the LPC 160 Mirror machine, our orbital polisher LPC 300 Mirror allows to polish and buff straight or bent tubes with round, oval, irregular section made of stainless steel, iron, aluminum, brass as well as other metals, with all diameters ranging from 5 to 114 mm.
Polishing the exhaust port is similar to the intake port, however, we want a much more mirror-like fi nish. Exhaust gases, containing carbon, build-up on exhaust port walls, restricting air fl ow. Th e mirror-like fi nish will help prevent future carbon build-up.

gear are all we need to construct this grinding machine. The wooden platform on the turntable is faced true, to permit a well-centered reflecting surface to be obtained. The main task of producing a perfect spherical concave surface should be solved by the use of a grinding tool swinging over the mirror blank like a pendulum.
The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, shown is the vertical milling machine. A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.
