Significant Accounting Policies [Text Block]	Note 2 Principles of Consolidation The consolidated financial statements include the accounts of CVD Equipment Corporation and its wholly owned subsidiar ies. In December 1998, April 1999, five 411519R, 555 555 Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company ’s significant estimates are the accounting for certain items such as revenues on long-term contracts recognized on the percentage-of-completion method, depreciation and amortization, valuation of inventories at the lower of cost or market; allowance for doubtful accounts receivable; valuation allowances for deferred tax assets, impairment considerations of long-lived assets and stock-based compensation and costs associated with product warranties. Revenue Recognition. We earn revenue from the sale of custom equipment to customers around the world. A large portion of our revenue is derived from contracts relating to the design, development or manufacture of complex equipment to a buyer’s specification and is recognized in accordance with FASB ASC 605 35. of-completion accounting method and generally recognize revenue based on the relationship of total costs incurred to total projected costs. Profits expected to be realized on such contracts are based on total estimated sales for the contract compared to total estimated costs, including warranty costs, at completion of the contract. Direct costs which include materials, labor and overhead are charged to work-in-progress (including our contracts-in-progress) inventory or cost of sales. Indirect costs relating to long-term contracts, which include expenses such as general and administrative, are charged to expense as incurred and are not We have been engaged in the production and delivery of goods on a continual basis under contractual arrangements for many years. Historically, we have demonstrated an ability to accurately estimate total revenues and total expenses relating to our long-term contracts. However, there exist many inherent risks and uncertainties in estimating revenues, expenses and progress toward completion, particularly on larger or longer-term contracts. If we do not may may Adoption of New Revenue Standard In May 2014, No. 2014 09, 606 five December 15, 2016; August 2015, No. 2015 14 2014 09 one The Company has completed its assessment of the impact that the standard will have on revenue recognition. The Company has reviewed contracts for all material revenue streams and assessed potential impacts on the Company ’s consolidated financial statements, results of operations, disclosures, and internal controls over financial reporting. The Company currently recognizes a significant majority of its revenue over time. Management has determined that this will remain materially consistent upon adoption of the new standard and no first 2018 Inventories Inventories are valued at the lower of cost (determined on the first first net realizable value. Income Taxes On December 22, 2017, 1986, not 35% 21%; December 31, 2017. Deferred tax assets and liabilities are determined based on the estimated future tax effects of temporary differences between the financial statements and tax bases of assets and liabilities, as measured by using the future enacted tax rates. Deferred tax expense (benefit) is the result of changes in the deferred tax assets and liabilities. The Company records a valuation allowance against deferred tax assets when it is more likely than not not Investment tax credits are accounted for by the flow-through method , reducing income taxes currently payable and the provision for income taxes in the period the assets giving rise to such credits are placed in service.

In addition, the parent company files standalone tax returns in California, Delaware, Michigan, Minnesota, New Hampshire and Wisconsin. The Company is no 2014. Long Lived Assets and Intangibles Long-lived assets consist primarily of property, plant, and equipment. Intangibles consist of patents, copyrights and intellectual property, licensing agreements and certifications.

However, it is reasonably possible that this estimate may Earnings Per Share Basic earnings per common share is computed by dividing the net income by the weighted average number of shares of common stock outstanding during each period. When applicable, diluted earnings per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents, consisting of shares that might be adjusted upon exercise of common stock options and warrants. Potential common shares issued are calculated using the treasury stock method, which recognizes the use of proceeds that could be obtained upon the exercise of options and warrants in computing diluted earnings per share. It assumes that any proceeds would be used to purchase common stock at the average market price of the common stock during the period. Cash and Cash Equivalents The Company had cash and cash equivalents of $ 14.2 $21.7 December 31, 2017 2016. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. The Company places its cash equivalents with high credit-quality financial institutions and invests its excess cash primarily in money market instruments. The Company has established guidelines relative to credit ratings and maturities that seek to maintain stability and liquidity. The Company sells products and services to various companies across several industries in the ordinary course of business. The Company routinely assesses the financial strength of its customers and maintains al lowances for anticipated losses based upon historical experience. Fair value of Financial Instruments The carrying amounts of financial instruments including cash and cash equivalents, accounts receivable, net, accounts payable and accrued expenses, deferred revenue and customer deposits approximate fair value due to the relatively short-term maturity of these instruments. The carrying value of long-term debt approximates fair value based on prevailing borrowing rates currently available for loans with similar terms and maturities. Business Combination The Company has accounted for its acquisitions of the assets of both Tantaline A/S and Mesoscribe Technologies, Inc. using the acquisition method. The Company has allocated the purchase price to the assets acquired based on their estimated fair values at the acquisition dates. Acquisition-Related Contingent Consideration Acquisition-related contingent consideration represents an obligation of the Company to transfer additional assets or equity interests if specified future events occur or conditions are met. This contingency is accounted for at fair value either as a liability or equity depending on the terms of the acquisition agreement. The Company determines the estimated fair value of contingent consideration as of the acquisition date, and subsequently at the end of each reporting period. In doing so, the Company makes significant estimates and assumptions regarding future events or conditions being achieved under the subject contingent agreement as well as the appropriate discount rate to apply. Stock-Based Compensation The Company records stock-based compensation in accordance with the provisions set forth in ASC 718, using the modified prospective method. ASC 718 Shipping and Handling It is the Company ’s policy to include freight charges billed to customers in total revenue. The amount included in revenue was $42,000 $28,000 December 31, 2017 2016, Recently Adopt ed A ccounting Pronouncement In May 2014, No. 2014 09, 606 five December 15, 2016; August 2015, No. 2015 14 2014 09 one The Company has completed its assessment of the impact that the standard will have on revenue recognition.

Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company ’s significant estimates are the accounting for certain items such as revenues on long-term contracts recognized on the percentage-of-completion method, depreciation and amortization, valuation of inventories at the lower of cost or market; allowance for doubtful accounts receivable; valuation allowances for deferred tax assets, impairment considerations of long-lived assets and stock-based compensation and costs associated with product warranties.

Indirect costs relating to long-term contracts, which include expenses such as general and administrative, are charged to expense as incurred and are not We have been engaged in the production and delivery of goods on a continual basis under contractual arrangements for many years.

Earnings Per Share, Policy [Policy Text Block]	Earnings Per Share Basic earnings per common share is computed by dividing the net income by the weighted average number of shares of common stock outstanding during each period. When applicable, diluted earnings per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents, consisting of shares that might be adjusted upon exercise of common stock options and warrants. Potential common shares issued are calculated using the treasury stock method, which recognizes the use of proceeds that could be obtained upon the exercise of options and warrants in computing diluted earnings per share. It assumes that any proceeds would be used to purchase common stock at the average market price of the common stock during the period.

Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair value of Financial Instruments The carrying amounts of financial instruments including cash and cash equivalents, accounts receivable, net, accounts payable and accrued expenses, deferred revenue and customer deposits approximate fair value due to the relatively short-term maturity of these instruments.

The Company has allocated the purchase price to the assets acquired based on their estimated fair values at the acquisition dates. Acquisition-Related Contingent Consideration Acquisition-related contingent consideration represents an obligation of the Company to transfer additional assets or equity interests if specified future events occur or conditions are met. This contingency is accounted for at fair value either as a liability or equity depending on the terms of the acquisition agreement. The Company determines the estimated fair value of contingent consideration as of the acquisition date, and subsequently at the end of each reporting period. In doing so, the Company makes significant estimates and assumptions regarding future events or conditions being achieved under the subject contingent agreement as well as the appropriate discount rate to apply.
