Maeda can complete the entire process in its own factory.
Made-to-order plating at 1/100 mm thinness. We are capable of an in-house, one-stop processing that includes precision machining, hard-chrome plating, polishing, and assembly. We are capable of processing high-quality products at low cost, quickly.
Hard chrome plating
Normal plating Chrome plating has superior wear resistance, lubricity, rust resistance, and corrosion resistance. It is applied on sliding surface hydraulic parts and used in dies and molds. The hardness of our electroplating is approximately 950 in Vickers’ hardness. Its high quality has earned praises. We are capable of plating rounded or squared objects on the inner or outer diameter, and partial plating. Thick plating Polishing and plating scratches and dents on, for instance, parts of devices that are being overhauled, implying that the part’s original size can be restored. We are capable of applying thick plating to products within demanding geometrical tolerances, dimensional tolerances, and surface roughnesses. Subsequent to the thick plating, we conduct in-house polishing and buffing to achieve the exact measurements required. Removal We can remove plating layers when a plated section needs to be processed again or new plating is required owing to the deterioration of the previous plate. At our company we mainly use polishing, hydrochloric acid exfoliation, and electrolytical exfoliation to remove plating. Generally, hydrochloric acid treatment is used for removal; however, electrolysis treatment can be used for relatively large pieces. Furthermore, we use cylindrical grinders to remove plating through polishing whenever possible.
Processing of round objects We have earned our customers’ trust and satisfaction through our expertise in the precision processing of hydraulic excitation devices, which we have acquired over several years of experience. Sizes we can process CNC lathe: total length 100–2200 mm and diameter 20–450 mm. General-purpose lathe: total length 50–4000 mm and diameter 15–800 mm. Materials we can process Carbon steel (SS400 and S45C) Cast iron (FC and FCD) Alloy steel (SCM and SNCM) Tool steel (SK, SKS, and SKD) Other metals/nonmetal (aluminum, copper, and titanium) Processing examples Piston, cylinder cover, and precision axis Processing of squared objects We can achieve high-precision processing with gate type/horizontal machining centers and general-purpose machines (milling machines and radial drill machines). Sizes we can process Gate type table: 2000 × 1000 and height 800 Horizontal type 1 table: 400 × 400, height 400, and 2 pallets Horizontal type 2 table: 1600 × 1800 Materials we can process Carbon steel (SS400 and S45C) Cast iron (FC and FCD) Alloy steel (SCM and SNCM) Tool steel (SK, SKS, and SKD) Other metals/nonmetal (aluminum, copper, and titanium)
Plane polishing We achieve finished surfaces with highly precise surface roughness and measurements using a plane grinder. We also perform special processing using jigs. As we use magnetic chucks, we are capable of processing magnetic materials. Sizes we can process Table: 400 × 600, height 450 Materials we can process Carbon steel (SS400 and S45C) Alloy steel (SCM and SNCM) Tool steel (SK, SKS, and SKD) Other metals/nonmetal (aluminum, copper, and titanium) Cylindrical polishing We also perform processing before and after chrome plating. Prior to the plating, we make the surface suitable, and after the plating, we perform processing to achieve the required measurements and treat the plated surface. We are also capable of achieving clean surfaces without changing the size through plating after scratch removal polishing. Sizes we can process Cylindrical polisher 1: Total length 1050 mm, Diameter 300 mm, Weight 80 kg Cylindrical polisher 2: Total length 2500 mm, Diameter 330 mm, Weight 500 kg Cylindrical polisher 3: Total length 2500 mm, Diameter 400 mm, Weight 500 kg Materials we can process Carbon steel (SS400 and S45C) Alloy steel (SCM and SNCM) Tool steel (SK, SKS, and SKD) Buff polishing We are capable of mirror polishing that gives the material a glossy surface. We perform this step after the chrome plating. The benefits include glossy and clean surfaces, improvements in lubricity and the removal of micro burrs. We perform surface finishing after plating of noncylindrical, uneven, or complex shapes with manual buffing. Sizes we can process Buff polisher: Total length 4000 mm, Diameter 600 mm Materials we can process Carbon steel (SS400 and S45C) Alloy steel (SCM and SNCM) Tool steel (SK, SKS, and SKD)
Special hydraulic cylinders and hydraulic systems
Special cylinders With our many achievements and abundant experiences, we can produce hydraulic cylinders for any purpose, including servo cylinders, presses, iron and steel making machines, and industrial machinery. (Currently, we do not produce vehicular cylinders.) Hydraulic devices We can support everything from design to production of hydraulic units that are suited to your machine facility and hydraulic devices such as on-site piping. Repair/overhauling of hydraulic cylinders Our company mainly conducts the design of hydraulic cylinder/labor-saving equipment, and we offer precision machine processing, hard chrome plating, assembly, and performance testing, in addition to our proposals for hydraulic cylinder repairs/durability improvements.
